This testing was extremely well done and well explained - great work! This makes me feel way more comfortable choosing a cooler that’ll be best for my build
Finally, someone trustful who actually tested gaming scenarios temps. Everyone is just rushing towards synthetic benchmark to hit the headroom of the CPU for their audience, but little did they know, most of their audience are gamers and are looking into gaming performance benchmark. Glad we got people at Hardware Canucks, who think outside the box. Who knew the 7000 series were running below 70c for gaming? Not me, well until now.
i agree but with a caveat. Unlike most people I'm not using my 7900x for gaming I actually am using it for heavy multi-core workloads of video encoding. So I'm actually happy that reviewers are focusing on just full all-core load performance. I am definitely seeing these high temps in the 90s with my 7900x, even with a 360 AIO and all fans and pump at 100%. The cpu is doing exactly what AMD "designed" it to do, although as you can guess I don't think they actually want it to hit 95C I think they just came up a really good excuse as to why the temps are so high. I actually was using a 280 AIO and hitting 95C so I bought a 360 AIO and it's only helped temps drop maybe two degrees. I'm thinking of maybe going into the BIOS and setting the max temp to 85C instead of 95C.
This video helped clarify alot, thanks! I was worried that my high temps (48-68c idle and 70-80c at load) were related to that whole exploding chip fiasco.
@@zakkeith1508 True, it depends on the size of the room and the air flow, however my 3080 and 9900k kick out a ridiculous amount of heat and cooling your room starts to become just as much of a problem as cooling your computer
What I'm waiting is to see the X3D version eventually, how the heat and clocks will be managed this time around. Should be interesting especially since they plan to release more models.
@@reptilespantoso for most people, they game. and CPUs aren't running 215 watts in gaming, probably between 70 -120. if you really care about your power bill and power consumption you should be more concerned about your gpu
Hi, thank you for the full explanation and greatly appreciated it. I tested the 7950x, yes it does stays 95 degrees but and clock frequency does depend on the cooler’s capabilities. But if you tweak in PBO2 by lowering the PPT by 1/2 which is 115w instead of 230w you can still hit the 5ghz mark with boost but with a lower temperature. I do agree with you if allow to, best is by getting the best cooler pc builders can get. Am running off a 420 aio which benefits the clock frequency and boost.
AMD handled really poorly their explanation about how their chips run. Intel chips have been running at 100°C if unchecked for years and no one bats an eye, AMD could've explained it a lot more better, also undervolting it with PBO2 makes it run way less hot without losing any performance. In my eyes this is a masterclass about how to fail at communicating with your consumer base.
Excellent charts, been looking at these for really heavy workloads so these kind of performance-loss to temperature charts really helps as a rough gauge. Thanks for doing this testing.
Thank you for going into the gaming bit. So many people think that when their cpu says 100 in game on an osd that it means the cpu is maxed out in every way. They also associate 100 usage to highest temp. This will go a long way to correct this issue with some.
This was very interesting. I recently bought a 7700X and the Wraith Prism fan ramping up and down due to temp spiking was driving me nuts. I had an old Deeopcool Gammax 400 that I put a Noctua fan on as a temporary solution...temps and frequencies are about the same as as the Prism but much quieter. During typical gaming sessions the 7700X hovers around ~70C with the Gammax 400.
I changed the cooler for the same reason, noise level. I even keep fan speed max 400RPM for all fans. Its fine for hardware to run hot and most of the cases there is no performance penalty.
Very informative video, where many/most scenarios are covered and explained. But after reading comments, there's still a lot confusion about HEAT. I've watched many Ryzen 7000 video "studies" talking about 95°C, where people keep asking about heat, but the only answer we get is "no worry, 95C is now 65C" -which (to me) sound like avoiding to answer & explain actual question. Saying (here in comments) "Just because something runs hot, doesn't mean it outputs more heat" isn't really helpful (even it's true!) -it needs an explanation. Not to mention stupid comments like "Gamers have proven with this launch that they REALLY don't get physics." What many wish, is the clear answer to the question: will now more heat come out of PC? And if yes, by how much? Measuring unit for amount of heat is Joule and measuring unit for power is Watt. How these two relate? The answer is: 1W=1J/second. We can see, that amount of heat only depends on power (equation doesn't contain temperature). That is, temperature has nothing to do with amount of heat. First thing that comes to mind is "wait... but 95°C is hotter than 65°C.. and so it must create more heat.". No, it doesn't! Here's an example which hopefully explain this: Let's assume we have a CPU (with some "normal" cooler), which has temperature of 95°C when powered by 100W. Now we only change the cooler with a better one and CPU temperature drops to 80°C. Does that mean, we generate less heat now? Of course not. Amount of heat can't just vanish by changing the cooler. By changing the cooler we only reduced CPU temperature -because better cooler dissipates (the same amount of heat) more efficient. Again, amount of heat only depends on input power. And this also explains the following claim: at given power, the amount of heat dissipated out of PC case remains the same, regardless of CPU temperature and what cooler is being used. In short: if one CPU has 95°C and another has 80°C, and both consume 100W, then both PC's will increase the room temperature by exactly the same amount (because both dissipate the same amount of heat). The only way to reduce (or increase) amount of heat, is by changing power. Thank you for reading
I have a noctua air cooler with three 140mm fans mounted in the top of my case blowing down on it and while I see temp spikes to 95C under heavy load, it immediately cools to under 50C the moment load is removed. Throttling until you hit your thermal cap is AMD's way of squeezing as much performance out of these things as possible.
as a gamer i run a 7600x and the ak620… 4k and 120fps and i’ve never tripped north of 60c or so. my cpu fans stay nice and quiet. all core work yes, the am5 chips are fuente. but for every day computing or gaming, you’ll be fine. great video, it helped me make my purchase.
To keep my 7950x under control, I set a maximum thermal limit of 85 C and set the PBO curve optimizer to undervolt by 10 mA on all cores (I didn't test going any lower, but I could potentially save more power/heat that way). I'm getting the same scores in cinebench as stock, but it never gets over 85 C. It keeps the fans from lifting off like a jet too.
yeah, the problem is not really the 95c temp of the CPU it's more the speed of the fans of the cooler which are causing issues. too loud. the fan curves are design to keep our CPU at a lower temp, new fan curves are required now. but yeah, CO can do a great job. we'll have to check the next bios updates, certainly some enhancement coming
@@willgart1 the IHS is twice as thick as last series, that's the problem. They should of made the chip so a simple IHS design would cover all the SMD hardware instead of what they did.
@@willgart1 I plan to just manually set my max fan speed to around 40%. In gaming it should never hit it. in rendering I will lose a few 100 mhz but my system stays quiet. So yeah, new fan curves ftw.
So basically I've been worrying about my 7700X hitting 95 degree with an 240mm AIO for nothing, thanks for the video! Makes me feel less stressed when I see the temps, haha!
@@simpledev6066 I'm just using the stock fan right now but I think I might get a liquid cooler just a squeeze a little bit more performance out of it. The only issue I have is I just wonder about the longevity of the CPU but I would imagine AMD did take that into consideration when they were building the processor in the first place.
@@ProfligateGhost I think they said that everything is fine and its designed to be this way, right now Im using my pc for about 10 hours and my min temps were 53 and max 82 hard multi tasking but I usually get 50-65
I've also figured out that one of the reasons why it was running hot was because my motherboard had precision boost overdrive on by default. I disabled it and now my temps are definitely about 60 maybe 70 when I'm gaming. And I haven't really noticed the performance hit at all. So that might help too
Hmmm. 7600X: Cyberpunk, 1080p, Ray Tray Ultra, after 15 minutes driving in downtown I get 87 degrees, with a giant ass Air Cooler, any of you in the similar boat?
I wish you had tested it with the power limitat set tl 105W or 65W. I've seen reviews saying there wasn't that big of a performance impact and thermals were a LOT tamer.
But why sacrifice performance? Its meant to be ran at 95. You cohld say fan noise i guess, or you could just tuen the fans down ans let the CPU just stay at 95c at lower freq.
@@conradical5941 7950x sometimes is 40+% better (almost to much considering 13% ipc uplift). Everyone was happy with how much better 5950x was then 3950x. So conclusion you can still have 25-35% improve, however without a penalty in heat, longevidity of cpu (95°C is not good for cpu period, my current one is 8 years old and will keep lasting cause of it's 65°C game workign temp.) The power consumption ALSO is gigantically much to high for 3-5% improvement (0% in gaming). Conclusion, 105 wat eco mode makes a ton of sense on the 7950x. You remove the 95°C spike temp in all but rendering, you remove the doubling of power usage, and you still retain a massive advantage over 5000 series, and you have am5 wich allows further upgrade.
@@des0lation_ Maybe you are right, maybe not, i don't wanna take the risk. Also the fact that the temps seem 'locked in the chip', not getting out (all sort of tests confirmed this, the bad head spreader locks the temps in), i really dont like. Secondly a 40-65°C gaming cpu (I5 3570k), already give some heat on the super hot days (38°C in schadows last year in belgium, new record). I dont want my pc to give heat. For me already going to 80-85° (wich is basically giving some leeway to amd, while i already love and prefer 65°) is the max for me. Going instantly to a perma 95° during heavy task, NO THANKS! You may like and trust it, i dont. Have you pur your hand in 45°C water? then try in 60 degree, or on metal that hot, or on stones in super hot day? It feels incredible destructive, for metal i trust it handles it, for transistor by transistor specific design, with some soldering? Nah. no way, maybe in early stages, but not later. Also amd could not have tested them for more then 2 years (24/7), i used this pc 8.5 years! And guess what, my new cpu will be higher end then ever, to make sure that it... wil last 8+ years. And guess what the longer the cpu must last, the lesser risks i can take, especially out of warranty, no thanks to 95°.
@@Matti6950"95°C is not good for cpu" "my current one is 8 years old and will keep lasting cause of it's 65°C" And this proves your point how exactly?

My Ryzen 9 7900X is around the 73 degrees when in play Battlefield 2042 on Ultra settings in 4K multiplayer. I use a Corsair H150i Elite XT LCD. 3 x 120mm fans...With a CPU stress test benchmark the CPU don't went higher then 91 degrees.
I was gonna upgrade my i7-3770K to a new Ryzen 7800X complete build, but have since decided to abandon this idea and instead buy a mini PC, which greatly lowers the overall cost.. Specifically I'm looking at the 6900HX with the RDNA2 integrated GPU, the GTR6 by Beelink coming out next month. For my needs this is the perfect desktop PC upgrade.
I like that the ak400 and ak620 are the ones representing the budget and high-end air cooling in these charts. These two coolers are absolute gem from deepcool and blows the majority of other air coolers out of the water in terms of price-to-perf in the current market. (I'm kinda biased coz I'm using the ak400 myself, such a nice cooler)
Absolutely excellent review. Just what I wanted to know. I'm still going to use a custom loop 120 in my DIY custom case, as it enables me to place the radiator in a separate open-air chamber outside the CPU Chamber. So the extracted heat will go nowhere near the motherboard. Similarly the GPU will be in its own open-air chamber. So both the CPU Cooler and GPU will draw fresh cold air and expell hot air back into the room. I had been hesitating between a 240 radiator and a 120 radiator plus 3 x 3.5" hot-swap drive bays for 2.5" SSDs. Now I know. So many thanks. BTW my whole case will fit in my briefcase.
thank god! I was worried that the thermal paste or the air cooler was bad or something (ID cooling 224 XTS), I am rocking a 7600 non X and the temperatures pass the 80°C while gaming (2-6 hours at day) so this is a relieve! This is all stock fan speed and fan curve including case fans and gpu fan curve so if I can tweak this and also see if I can undervolt the cpu so I can reduce the temps and make it stay at least 75°C or less. Note that the Case is a Matrexx 50 all tempered glass with 4 fans preinstalled (bad choice for temps, there is a same model of the case with mesh in the front panel so in case you are wanting to buy this same one, I would recommend going mesh in the front panel). Edit: I had a FX8350 in the past and boy that thing went 90°C with stock cooler and with a shitty case from the early 2000s, I remember to this day the fan going 7000rpm and it felt like a plane taking off inside my house. So I had a little PTSD while monitoring the temps on this one.
is it normal for my 7900X to run at 76C at idle with the browser open? I keep reading on reddit that most people at idle are 50C or below. Only on the first day i had it idling at 50 and now its never below 75C .. mostly 75-82
Man, this video is a gem, thank you!!! I ordered a AK620 today before been able to watch this video (to most likely go with a R5 7600X), but after watching this video Im starting to think its a bit overkill - for gaming only. A smaller cooler would probably be easy to install and be more compatible with motherboard and RAM.... Now I do not know what to do... should I go with the AK400 or Arctic Freezer 34 esports duo or similar options?
@@oscargranath93 The cooler is very good, but yeah in my particular case I had trouble because my RAM is very tall. Im waiting for free time to be able to do the change in my current system, Ryzen 5 3600. I think removing the front fan will be the easiest solution and Im guessing will still bring very good temps when loaded. I will also see if I can add the front fan to the back lol, perhaps it will help there. Once Im able to upgrade to a Ryzen 5 7600 (non-X) I will get smaller DDR5 RAM sticks so I can put the front cooler back. (Saldy where I live stock are very bad and prices have gone through the rooft).
This is awesome! I just got a deep cool ls520 because I have the MSI k240 and the temps seemed off, but after looking at all the videos the temps seem fine. Now I'm just looking into which seemed likes better quality product and the possible longevity of the coolers.
Got introduced to this problem with the 5800X, after extensive reading and finding the quote from the AMD engineer themselves that it was designed to do this, I admitted defeated and became content with the 90c it was hitting. I was able to get a NH-D15 and it made max under 80c now, AMD are just doubling down on this mindset with 7000. It's just trying to boost as much as it can and any tweaks are at the cost of performance, so it all comes down to what you value more, temps or performance.
Yeah I've got a bad sample 5950X, combined with a board that seems to run it hotter still. I managed to compare it to someone else's in a smaller case with a smaller cooler, and it was 20C cooler at stock. PBO was even better without even needing core optimizer on theirs.
Laptops are cooling limited. On a desktop people can and will install coolers that can cool it. And the thick IHS is very bad, people will be risking the CPU and void the warranty for sure to deal with it. Specially if people actually want to overclock it and aim for the best performance.
@@DJCryonic I would wager AMD could invent a new metal alloy or use one that is already known to cut down the thickness and raise the thermal conductivity. That's one area I would do some research on to see if it's possible and profitable, if I was in charge. I have a feeling they are looking into it.
@@dakoderii4221 The products will probably not change. What is most likely - people will just be fixing it on their own. Delidding or lapping the CPU is not new. While delidding is risky, lapping is not and requires just some work but it voids the warranty and makes it hard to sell the CPU. But I would for example, of course considering the mounting bracket - maybe that one needs to go too.
@@HardwareCanucks That does not matter tho. On a desktop people expect peak performance from such hardware, specially the 7950x - and this is where more thermal headroom means more performance. PBO can go way higher if the CPU is actually cold enough. There is no reason to hit the thermal wall on a desktop ever if the case is big enough for a good cooler.
Yep, I get nowhere near 95 in everyday use or gaming so never was a worry in my book. The only time I see high temps is with the artificial stress tests.
A great explanation Mike 😇👍 about how the processor works and for most people, gamers, you don’t need a super high cooler for max per 😱🤯🤩👍. I’ve been commenting for over 10yrs now that mobile tech will be the future of pc going into the future, and it appears that Ryzen 7000 CPUs are doing that as you explained. I feel the future of tech is going be truely amazing 🤩
The thing about these 7000 CPUs is that with such an inefficient way of delivering heat out of the CPU dies, whether it's gaming or production, the bigger question is whether these CPUs are able to sustain these performance long-term without seeing significant degradation. It is more or less common sense that the hotter CPUs are, the faster they tend to lose its performance over time. You have to keep in mind that these CPUs are pushing to the limits of the silicon with little headroom, so from a purely logical perspective they are less viable for sustainability when compared to Intel's 12th gen (or possibly 13th gen) non-K, or even AMD's own previous generation. Really makes me think AMD tried to stretch this one more than they could swallow.
Exactly what I meant in my comment. The max silicon can handle is the 5700G which is not coincidence the last processor which came with an AMD cooler included. That has 8 cores and goes to about 4.65 Mhz frequency. Thats about the top air cooling can handle. These AM5 CPU's will fail after a few years of use most likely since the same materials are used as for the 100 Celsius max temp AM4 system.
I have to assume that AMD is going to change these parameters with their upcoming Zen 4 notebook lines. 95 C is too hot IMO. Yes, I am only running a Comet Lake i7, but it never goes above 85 C, and most times it runs far cooler, like 70 C in gaming. That is also because I put better thermal paste and have some undervolting going. 95 C would also make a laptop way too warm for comfort. I really like where AMD is going with their CPU's, and the whole X3D line. And their financials show they are doing decently. But is this really a good idea, in the long run, to have immediate spikes up to 95 C? I guess logic tells me that this will limit the life of the chip, which sucks. And "heat soak" is a BAD thing, whether we are talking electronics or modern vehicles with forced induction engines. It kills performance. I am interested to see where AMD goes with Zen 5 and if they tweak this idea of running things so hot.
this is true for Intel Alderlake as well. You can keep almost all of your performance for realistic workloads with cheaper cooler. Nobody runs Cinebench MT 24/7.
I've tried like 30 games now but maybe you can suggest some? Even Civ during end time cycles / AI keeps cool since the load is so short on such a high end CPU.
@@HardwareCanucks to answer that question, I'm currently running the 7700x with the noctua nh-u12a cooler. While playing escape from tarkov, it seems to actually hit the 95c mark. I haven't tested any other games yet but it still bothers me that it hits those high temps
Hardware Canucks is doing very well on the Ryzen 7000 reviews and solutions. You guys seem not to be fully NDA mouth shut to talk about concerns where the consumers should look at. Bravo!
Ok so I’m a little confused. I have the Ryzen 5 7600x and a deepcool LT720. And any time I download a game or put any stress on the cpu it almost instantly shoots up to around 90 degrees Celsius. And even in some games it will shoot up to that point. But I’m curious if that’s normal or can I turn down the clock speed in bios and feel more relaxed.
i really wanna see a person who runs fans on 100% :D ill be not surprised if EK or other brands start releasing backplate(mean behind the motherboard) water cooling to absorb heat.
It would be nice to also see the measured TDP with these charts: how much more power and voltage can be fed to the CPU under better coolers. I guess that's ultimately what determines the clock speeds that can be reached? And on that note, if higher temperatures need more voltage (and power) for the same stability, would be interesting to see how these CPUs could be tuned to perform on lower target temperatures. Though on the other hand, the higher the temperature delta, the better the heat transfer is, and that again means more power and voltage for the higher clocks...
I honestly don’t know what you are talking about. My 7600X with an air cooler (upHere P5K) and temps around 40s idle, not over 70 full load. I have not done anything except enable the XMP or (DOC).
I just got a Ryzen 5 7600 and it runs 50-60 C when idle/web browsing and 80-90 C when playing Helldivers 2. I tried to reapply thermal paste, lower CPU voltage, increase fan speed, still the same. I'm feel a little better after watching this video.
7000 series performance improvement is great but my 5950x can maintain all cores workload at under 68-70 in renderings and under 73 at gaming with 130W.
@@Azmodaeus49 Might as well do two useful things with that energy rather than just one. I mine crypto when it is cold. Why pay for heat and not get paid a little back? Or if you're gaming, you can reduce the thermostat since you're already producing some heat. Spring/Summertime and this system falls apart. Fall and it's back in business.
Hook both up to that thermal electric cooler(2,400 watts) that LTT made. What's that total with the 7950x and 4090? About 3,000+ watts? That'll heat a small home! 🤔😮
This is the video I've been looking for a long time. Like a did a week worth of research on whether I should pick AIO or Air cooler once I get a 7950x3D. Now I can be confident that a good Air Cooler like the D15 can perform on par with other good liquid coolers.
Well, I've just installed my 7950x with a Dark Rock Pro 4 aircooler earlier today, and at idle it sits around 45-50 degrees celcius.. Right after I placed my order, I looked around a bit, tempering my anticipation, and was slightly concerned that almost all of the builds I saw being done with that CPU used beefy AIOs, and people talked as if air coolers are impossible to even think of using with it because "oh noo it'll throttle!!1one".. But it works just fine. Sure when I load the CPU as heavily as I can, it hits the 95 degrees, and there is a drop of about 85hz (maybe I was a little lucky in the silicon lottery), but that's synthetic load testing.. 20 minute hammer test, which doesn't at all resemble the heaviest stuff i'm doing myself, which is at most around 5 minutes of heavy loads here and there maybe up to 10 minutes, and that doesn't even bring it to the throttle point, at most it hits around 80-85 before my actual work loads are done, and usually I'll start those and walk away to do some dishes or something, so by the time i'm back to review, it's back down to the 45-50 degree idle temp again, ready for another run. I'm well satisfied with the 7950x on air so far. That got to be a bit of a longer comment than I intended.. anyway.. TLDR: big beefy air coolers work just fine all the way up to the 7950x, provided your workloads aren't long you won't even get to the point where you could feasibly 'notice' throttling :P (My heavier workloads are mainly some occasional molecular/atomic simulations, lighter workloads being BLASTing some DNA/RNA sequences - I suspect video editors especially might want to plan cooling solutions for longer workload runs)
Honestly, I got an AIO but it was only so I could mount it on the top (as exhaust). I know it's probably not helping my CPU performance much, but what it does do is it takes all the heat from the CPU and sends it directly out the top of the case, so it doesn't heat up anything else in the system. Which is still probably a very marginal benefit, but it's something.
My 7600 idles at around 70C and gaming stays at 95-96C with the stock cooler. At first i was worried until i did more research. I knew they ran hot but not that hot. I knew 100c was bad. I'm undervolting it tomorrow and I'm getting an AIO in about 2 months. I want to get one with a temperature readout on it. The last one I ordered, I saw a great deal, I'd been drinking, and ordered one with only intel mounts without noticing. Yes, I could have ordered mounts for it, but I'd rather just get one that I know the mounts are going to work with because it came with them.
As an owner of a Ryzen 9 9950x and using an Arctic Liquid Freezer II 360 AIO, I can safely say that this chip runs HOT even at idle...You're talking 50-63 degrees almost constantly as an average. Then when in games (depending on the game) it can average anywhere between 75-83-ish degrees. Then in 3D rendering it lingers around 89-93 degrees. I thought at first that maybe I simply misplaced the CPU AIO pump a little, but no...they're just REALLY hot chips compared to Intel. Also, I use MX-6 thermal paste (spread method) and run my chip at stock 200W.
Fantastic video. I've never been a fan of AIOs so I brought my Dark Rock Pro 4 forward from my 3900x build to my new 7950x. The very minor loss in performance on extremely heavy workloads is fine by me. The only other thing I wanted to see that this video did not cover is how long it takes to return to a baseline temperature after being on a max load for a sufficiently extended period of time.
The last few minutes were gold. Real world benchmark is the GOAT. All that stress test thrown everywhere from HUB to GNexus made people feel like they were going to be burning their house with these cpus on an air cooler. My AS500 Plus is going to rock this bad boy.
Very good test. Looks like I'm gonna get a 360 AIO and upgrade the fans to the Phanteks T30 to keep my Blender renders in check. However you left out one question: What about undervolting? Does it reduce temps?
Yes it can help but 95C may be hit anyways just at higher speeds, you also do have the option on most boards to override the 95C temperature target. For example you can set your board to a target of 85C, which will result in a small performance loss obviously, but for extreme sustained workloads may be worth it in terms of performance per watt as well. My personal plan due to working in a sound sensitive environment (music studio) is to manually cap the fans at around 40%, and set the temp target to 85C. In theory the PBO should take care of the rest and find the frequency that works to achieve that fan speed and temp balance. tl;dr you pick the temperature and the chip will ramp up until it hits that temperature. CPU cooler decides raw peak performance rather than the temps as the temps will be the ramp target.
Most fan curves are based on temperature. Doesn't this mean that most computers are going to be running their fans at max regardless of the current workload on the CPU?
I figured the CPU would be running at about 60-70C while gaming and nice to see i'm not too far off. I hate when all the reviews mentioned about thermals and all they did was test underload with cinebench. I then saw pauls hardware review where he took different coolers and found that the cpu didn't care. He then showed using PBO and applying the most aggresive setting, it lowered voltage, temps and raised the clock a bit more. When i get my 7000 series, the first thing i'm going to do is voltage tune it or use PBO
What I do not get is why do you need to run PBO to get the best out of the CPU? AMD shouldhave optimised the CPU out of the box to run at it's most effecient. Yes for a certain group overclocking and undervolting is a big thing but boy are these CPU's running a bit hot...
The temp difference between AM4 and AM5 surprised me. I thought the pc would shut down at high temps. This video has calmed my nerves. All is normal. I have a 360 AIO on a 7900x3d.
I need an air cooler for my Ryzen 7 5800x. for AAA games. and from this video I will guide you which ones could be used... if it does not reach 90 degrees and the pc freezes, it does not turn off automatically as they say.
Great video, and I know it's a little old. Just got my first rzyen CPU. I wonder if there is really an advantage to undervolt the CPU for max'ing performance?
I hope the 8000 series doesn't accommodate for older coolers with artificial Z-height in the IHS. That and adjusting the values in the curve optimizer should give the respin lower temps with more boost headroom.
Need only takes 2 clicks in the bios to make it cool and fast. Curve optimizer -30 or as much as your processor will allow and lock the temperature at 75 degrees.
lets assume amd made these to run at 95c, what about rest of the motherboard and components on it, theres ram, theres nvme drives, even vrms and everything close enough together to be affected by something heated up to a boiling point. everything runs quite warmer bcos of this. somethings gotta give.
@@HardwareCanucks it being unable to push that heat efectively to the cooler means it is that hot in that socket and all surounding area. It may not produce more heat but is unable to transfer heat away wich ands being the same
So the Optimum operating temperature is 82 deg c ? Would it hurt the shelf life of AIO or cause water leakage, to have close to boiling water, example 95 deg c water, fluid flowing about in the rubber or plastic tubing and pump head ?

Finally, someone trustful who actually tested gaming scenarios temps. Everyone is just rushing towards synthetic benchmark to hit the headroom of the CPU for their audience, but little did they know, most of their audience are gamers and are looking into gaming performance benchmark. Glad we got people at Hardware Canucks, who think outside the box. Who knew the 7000 series were running below 70c for gaming? Not me, well until now.
Exactly.
i agree but with a caveat. Unlike most people I'm not using my 7900x for gaming I actually am using it for heavy multi-core workloads of video encoding. So I'm actually happy that reviewers are focusing on just full all-core load performance. I am definitely seeing these high temps in the 90s with my 7900x, even with a 360 AIO and all fans and pump at 100%. The cpu is doing exactly what AMD "designed" it to do, although as you can guess I don't think they actually want it to hit 95C I think they just came up a really good excuse as to why the temps are so high. I actually was using a 280 AIO and hitting 95C so I bought a 360 AIO and it's only helped temps drop maybe two degrees. I'm thinking of maybe going into the BIOS and setting the max temp to 85C instead of 95C.
This review I found much more informative and realistic than artificial stress testing. Cheers.
This video helped clarify alot, thanks! I was worried that my high temps (48-68c idle and 70-80c at load) were related to that whole exploding chip fiasco.
So Ryzen 7000 has made liquid cooling redundant, that is ironically cool.
Yes but no, more cooling = more performance at high temps. If your room gets too hot then it becomes redundant.
Kinda it’s more what cooler you use determines your cpu power/ghz
@@schwalmy8227 your room isn't going to simply get more hot because of your computer. Thermal dynamics doesn't work that way
@@zakkeith1508 True, it depends on the size of the room and the air flow, however my 3080 and 9900k kick out a ridiculous amount of heat and cooling your room starts to become just as much of a problem as cooling your computer
@ÃTrollÄššÑigga Then next big thing will be chimney heat pipes attached to PC case, other end connected to room exhaust fan 😁😁
What I'm waiting is to see the X3D version eventually, how the heat and clocks will be managed this time around. Should be interesting especially since they plan to release more models.
@Andy Ruse This is my hope too. I'm excited by the idea that they still hit 95C but can push way faster 😄
@Andy Ruse x3d versions have the same die height so ihs will be the same
It's idiotic to run these CPUs stock. You need to run these undervolted, or at least in ECO mode. That's how you manage power consumption and heat.
@@reptilespantoso for most people, they game. and CPUs aren't running 215 watts in gaming, probably between 70 -120. if you really care about your power bill and power consumption you should be more concerned about your gpu

Mike's cooler videos are imo the absolute best content Hardware Canucks makes. It really revitalised the channel.
Oh thanks! - Mike
Hi, thank you for the full explanation and greatly appreciated it. I tested the 7950x, yes it does stays 95 degrees but and clock frequency does depend on the cooler’s capabilities. But if you tweak in PBO2 by lowering the PPT by 1/2 which is 115w instead of 230w you can still hit the 5ghz mark with boost but with a lower temperature. I do agree with you if allow to, best is by getting the best cooler pc builders can get. Am running off a 420 aio which benefits the clock frequency and boost.
AMD handled really poorly their explanation about how their chips run. Intel chips have been running at 100°C if unchecked for years and no one bats an eye, AMD could've explained it a lot more better, also undervolting it with PBO2 makes it run way less hot without losing any performance. In my eyes this is a masterclass about how to fail at communicating with your consumer base.
Excellent charts, been looking at these for really heavy workloads so these kind of performance-loss to temperature charts really helps as a rough gauge. Thanks for doing this testing.
Thanks for the credit. It took a while to figure out how to display the results. Glad to hear it worked out. :)
Thank you for going into the gaming bit. So many people think that when their cpu says 100 in game on an osd that it means the cpu is maxed out in every way. They also associate 100 usage to highest temp. This will go a long way to correct this issue with some.
This was very interesting. I recently bought a 7700X and the Wraith Prism fan ramping up and down due to temp spiking was driving me nuts. I had an old Deeopcool Gammax 400 that I put a Noctua fan on as a temporary solution...temps and frequencies are about the same as as the Prism but much quieter. During typical gaming sessions the 7700X hovers around ~70C with the Gammax 400.
I changed the cooler for the same reason, noise level. I even keep fan speed max 400RPM for all fans. Its fine for hardware to run hot and most of the cases there is no performance penalty.
Very informative video, where many/most scenarios are covered and explained. But after reading comments, there's still a lot confusion about HEAT. I've watched many Ryzen 7000 video "studies" talking about 95°C, where people keep asking about heat, but the only answer we get is "no worry, 95C is now 65C" -which (to me) sound like avoiding to answer & explain actual question. Saying (here in comments) "Just because something runs hot, doesn't mean it outputs more heat" isn't really helpful (even it's true!) -it needs an explanation. Not to mention stupid comments like "Gamers have proven with this launch that they REALLY don't get physics." What many wish, is the clear answer to the question: will now more heat come out of PC? And if yes, by how much?
Measuring unit for amount of heat is Joule and measuring unit for power is Watt. How these two relate? The answer is: 1W=1J/second. We can see, that amount of heat only depends on power (equation doesn't contain temperature). That is, temperature has nothing to do with amount of heat. First thing that comes to mind is "wait... but 95°C is hotter than 65°C.. and so it must create more heat.". No, it doesn't! Here's an example which hopefully explain this:
Let's assume we have a CPU (with some "normal" cooler), which has temperature of 95°C when powered by 100W. Now we only change the cooler with a better one and CPU temperature drops to 80°C. Does that mean, we generate less heat now? Of course not. Amount of heat can't just vanish by changing the cooler. By changing the cooler we only reduced CPU temperature -because better cooler dissipates (the same amount of heat) more efficient. Again, amount of heat only depends on input power. And this also explains the following claim: at given power, the amount of heat dissipated out of PC case remains the same, regardless of CPU temperature and what cooler is being used.
In short: if one CPU has 95°C and another has 80°C, and both consume 100W, then both PC's will increase the room temperature by exactly the same amount (because both dissipate the same amount of heat). The only way to reduce (or increase) amount of heat, is by changing power.
Thank you for reading
I have a noctua air cooler with three 140mm fans mounted in the top of my case blowing down on it and while I see temp spikes to 95C under heavy load, it immediately cools to under 50C the moment load is removed. Throttling until you hit your thermal cap is AMD's way of squeezing as much performance out of these things as possible.
yet when it reaches over 95 degrees, i get a warning on my pc that the cpu is over heating. At what degree do we know its ACTUALLY overheating ?
a lot of people dont understand there is a difference in heat output from a cpu
between 95c 50watts and 95c at 100 watts
I'm seeing that in some comments. Just because something runs hot, doesn't mean it outputs more heat.
Gamers have proven with this launch that they REALLY don't get physics.
the great things about these CPU's is that you can under volt them lower the over all temps and get BETTER performance.
as a gamer i run a 7600x and the ak620… 4k and 120fps and i’ve never tripped north of 60c or so. my cpu fans stay nice and quiet. all core work yes, the am5 chips are fuente. but for every day computing or gaming, you’ll be fine. great video, it helped me make my purchase.
To keep my 7950x under control, I set a maximum thermal limit of 85 C and set the PBO curve optimizer to undervolt by 10 mA on all cores (I didn't test going any lower, but I could potentially save more power/heat that way). I'm getting the same scores in cinebench as stock, but it never gets over 85 C. It keeps the fans from lifting off like a jet too.
yeah, the problem is not really the 95c temp of the CPU
it's more the speed of the fans of the cooler which are causing issues. too loud.
the fan curves are design to keep our CPU at a lower temp, new fan curves are required now.
but yeah, CO can do a great job.
we'll have to check the next bios updates, certainly some enhancement coming
Can always manually set fans or make a custom curve
@@willgart1 the IHS is twice as thick as last series, that's the problem. They should of made the chip so a simple IHS design would cover all the SMD hardware instead of what they did.

@@simpledev6066 I'm just using the stock fan right now but I think I might get a liquid cooler just a squeeze a little bit more performance out of it.

@@ProfligateGhost I think they said that everything is fine and its designed to be this way, right now Im using my pc for about 10 hours and my min temps were 53 and max 82 hard multi tasking but I usually get 50-65
Yeah, I was downloading Microsoft Flight Simulator last night, and was worried that it was at a constant 75 degrees C
I've also figured out that one of the reasons why it was running hot was because my motherboard had precision boost overdrive on by default. I disabled it and now my temps are definitely about 60 maybe 70 when I'm gaming. And I haven't really noticed the performance hit at all. So that might help too
They did say the maximum possible temperature is 115c, though they set the Tjmax to 95c. So I guess 95c is the new 80c (for 100c max temp)
These illustrations are top notch and make the issue very clear, great video thank you guys for the hard work
Hmmm. 7600X: Cyberpunk, 1080p, Ray Tray Ultra, after 15 minutes driving in downtown I get 87 degrees, with a giant ass Air Cooler, any of you in the similar boat?
very nice to see that budget coolers are viable for ryzen 7000 series
they are viable because nothing can pull down the temps, so its a win by surrender lmao
Yes it does, it gets hot enough where I live. But the 7950X's 105W eco mode is where it's at.
I wish you had tested it with the power limitat set tl 105W or 65W. I've seen reviews saying there wasn't that big of a performance impact and thermals were a LOT tamer.
But why sacrifice performance? Its meant to be ran at 95. You cohld say fan noise i guess, or you could just tuen the fans down ans let the CPU just stay at 95c at lower freq.
@@conradical5941 7950x sometimes is 40+% better (almost to much considering 13% ipc uplift). Everyone was happy with how much better 5950x was then 3950x. So conclusion you can still have 25-35% improve, however without a penalty in heat, longevidity of cpu (95°C is not good for cpu period, my current one is 8 years old and will keep lasting cause of it's 65°C game workign temp.) The power consumption ALSO is gigantically much to high for 3-5% improvement (0% in gaming). Conclusion, 105 wat eco mode makes a ton of sense on the 7950x. You remove the 95°C spike temp in all but rendering, you remove the doubling of power usage, and you still retain a massive advantage over 5000 series, and you have am5 wich allows further upgrade.
@@des0lation_ Maybe you are right, maybe not, i don't wanna take the risk. Also the fact that the temps seem 'locked in the chip', not getting out (all sort of tests confirmed this, the bad head spreader locks the temps in), i really dont like.

Also amd could not have tested them for more then 2 years (24/7), i used this pc 8.5 years! And guess what, my new cpu will be higher end then ever, to make sure that it... wil last 8+ years.

Best (most informative/useful) damn 7000 series content I’ve seen yet
I like that the ak400 and ak620 are the ones representing the budget and high-end air cooling in these charts. These two coolers are absolute gem from deepcool and blows the majority of other air coolers out of the water in terms of price-to-perf in the current market.
(I'm kinda biased coz I'm using the ak400 myself, such a nice cooler)
Absolutely excellent review. Just what I wanted to know. I'm still going to use a custom loop 120 in my DIY custom case, as it enables me to place the radiator in a separate open-air chamber outside the CPU Chamber. So the extracted heat will go nowhere near the motherboard. Similarly the GPU will be in its own open-air chamber. So both the CPU Cooler and GPU will draw fresh cold air and expell hot air back into the room. I had been hesitating between a 240 radiator and a 120 radiator plus 3 x 3.5" hot-swap drive bays for 2.5" SSDs. Now I know. So many thanks. BTW my whole case will fit in my briefcase.
just because it's "by design" doesn't necessarily mean it's ideal. i can't imagine the lifespan of the ryzen 7000 lasting long because of it.
thank god! I was worried that the thermal paste or the air cooler was bad or something (ID cooling 224 XTS), I am rocking a 7600 non X and the temperatures pass the 80°C while gaming (2-6 hours at day) so this is a relieve! This is all stock fan speed and fan curve including case fans and gpu fan curve so if I can tweak this and also see if I can undervolt the cpu so I can reduce the temps and make it stay at least 75°C or less. Note that the Case is a Matrexx 50 all tempered glass with 4 fans preinstalled (bad choice for temps, there is a same model of the case with mesh in the front panel so in case you are wanting to buy this same one, I would recommend going mesh in the front panel).
Edit: I had a FX8350 in the past and boy that thing went 90°C with stock cooler and with a shitty case from the early 2000s, I remember to this day the fan going 7000rpm and it felt like a plane taking off inside my house. So I had a little PTSD while monitoring the temps on this one.
Great video! Thank you for all your effort. Is nice to know that the heat is manageable. Now it only the motherboard and memory prices would go down.
And the CPU prices.
This was very informative.. Thank you. Just bought a Ryzen 5 7600x and the budget cooler. Guess I should consider upgrading. :)
Great video explaining the weird temperatures I get from my 7600x. Thank you so much!
What was the boost behaviour like on the 7600x in game? Did it hold 5.4ghz steady on the AK620?
It's hard to say "steady" since every game load is different.
is it normal for my 7900X to run at 76C at idle with the browser open? I keep reading on reddit that most people at idle are 50C or below. Only on the first day i had it idling at 50 and now its never below 75C .. mostly 75-82
It's normal. My CPU did the same and I have a 360mm XPG water cooler
This review changed my mind about the 7000 series. Now I wonder how the mobile processors will perform.
Man, this video is a gem, thank you!!!
I ordered a AK620 today before been able to watch this video (to most likely go with a R5 7600X), but after watching this video Im starting to think its a bit overkill - for gaming only.
A smaller cooler would probably be easy to install and be more compatible with motherboard and RAM.... Now I do not know what to do... should I go with the AK400 or Arctic Freezer 34 esports duo or similar options?
The AK620 is perfect, especially if you run into an odd scenario where a game loads the CPU a bit more.
How did it go? Are you happy with your decision?
@@oscargranath93 The cooler is very good, but yeah in my particular case I had trouble because my RAM is very tall. Im waiting for free time to be able to do the change in my current system, Ryzen 5 3600.

I will also see if I can add the front fan to the back lol, perhaps it will help there.

I was able to get a NH-D15 and it made max under 80c now, AMD are just doubling down on this mindset with 7000.
It's just trying to boost as much as it can and any tweaks are at the cost of performance, so it all comes down to what you value more, temps or performance.
Yeah I've got a bad sample 5950X, combined with a board that seems to run it hotter still. I managed to compare it to someone else's in a smaller case with a smaller cooler, and it was 20C cooler at stock. PBO was even better without even needing core optimizer on theirs.

The "too hot" argument is just lack of understanding of thermodynamics and people who don't own laptops.
Laptops are cooling limited. On a desktop people can and will install coolers that can cool it. And the thick IHS is very bad, people will be risking the CPU and void the warranty for sure to deal with it. Specially if people actually want to overclock it and aim for the best performance.
@@DJCryonic I would wager AMD could invent a new metal alloy or use one that is already known to cut down the thickness and raise the thermal conductivity.

@@dakoderii4221 The products will probably not change. What is most likely - people will just be fixing it on their own. Delidding or lapping the CPU is not new. While delidding is risky, lapping is not and requires just some work but it voids the warranty and makes it hard to sell the CPU. But I would for example, of course considering the mounting bracket - maybe that one needs to go too.

@@HardwareCanucks That does not matter tho. On a desktop people expect peak performance from such hardware, specially the 7950x - and this is where more thermal headroom means more performance. PBO can go way higher if the CPU is actually cold enough. There is no reason to hit the thermal wall on a desktop ever if the case is big enough for a good cooler.
Yep, I get nowhere near 95 in everyday use or gaming so never was a worry in my book. The only time I see high temps is with the artificial stress tests.
A great explanation Mike 😇👍 about how the processor works and for most people, gamers, you don’t need a super high cooler for max per 😱🤯🤩👍. I’ve been commenting for over 10yrs now that mobile tech will be the future of pc going into the future, and it appears that Ryzen 7000 CPUs are doing that as you explained. I feel the future of tech is going be truely amazing 🤩
Basically, your CPU performance wasn't just based on your CPU alone but the cooler too.
Just wait for the delid kits 20+ c reduction in temps we will again see new IHS hopefully thinner. Can't wait for derba8er delid and direct die frame.
So buy an additional load of kiddie designed expensive crap to fix an overheating, overpriced processor. Er, OK.
Great info here thank you!
Would be interested to see these with Noctua’s new cooler and de8aur’s dilidding tool.
The thing about these 7000 CPUs is that with such an inefficient way of delivering heat out of the CPU dies, whether it's gaming or production, the bigger question is whether these CPUs are able to sustain these performance long-term without seeing significant degradation. It is more or less common sense that the hotter CPUs are, the faster they tend to lose its performance over time. You have to keep in mind that these CPUs are pushing to the limits of the silicon with little headroom, so from a purely logical perspective they are less viable for sustainability when compared to Intel's 12th gen (or possibly 13th gen) non-K, or even AMD's own previous generation. Really makes me think AMD tried to stretch this one more than they could swallow.
Exactly what I meant in my comment. The max silicon can handle is the 5700G which is not coincidence the last processor which came with an AMD cooler included. That has 8 cores and goes to about 4.65 Mhz frequency. Thats about the top air cooling can handle. These AM5 CPU's will fail after a few years of use most likely since the same materials are used as for the 100 Celsius max temp AM4 system.
I have to assume that AMD is going to change these parameters with their upcoming Zen 4 notebook lines. 95 C is too hot IMO. Yes, I am only running a Comet Lake i7, but it never goes above 85 C, and most times it runs far cooler, like 70 C in gaming. That is also because I put better thermal paste and have some undervolting going. 95 C would also make a laptop way too warm for comfort.
I really like where AMD is going with their CPU's, and the whole X3D line. And their financials show they are doing decently. But is this really a good idea, in the long run, to have immediate spikes up to 95 C? I guess logic tells me that this will limit the life of the chip, which sucks. And "heat soak" is a BAD thing, whether we are talking electronics or modern vehicles with forced induction engines. It kills performance. I am interested to see where AMD goes with Zen 5 and if they tweak this idea of running things so hot.
this is true for Intel Alderlake as well. You can keep almost all of your performance for realistic workloads with cheaper cooler. Nobody runs Cinebench MT 24/7.
Would be very interesting to see the temperatures of Ryzen 7000 series on games extremely CPU dependant.
I've tried like 30 games now but maybe you can suggest some? Even Civ during end time cycles / AI keeps cool since the load is so short on such a high end CPU.
That data is out there. They run fairly cool, because it's mostly single core workload. Get the 6 core 7600x. More cores is nonsense.
@@HardwareCanucks to answer that question, I'm currently running the 7700x with the noctua nh-u12a cooler. While playing escape from tarkov, it seems to actually hit the 95c mark. I haven't tested any other games yet but it still bothers me that it hits those high temps

Ok so I’m a little confused. I have the Ryzen 5 7600x and a deepcool LT720. And any time I download a game or put any stress on the cpu it almost instantly shoots up to around 90 degrees Celsius. And even in some games it will shoot up to that point. But I’m curious if that’s normal or can I turn down the clock speed in bios and feel more relaxed.
i really wanna see a person who runs fans on 100% :D
ill be not surprised if EK or other brands start releasing backplate(mean behind the motherboard) water cooling to absorb heat.
Really well explained. Here I was, going worried crazy over the 95 degrees occasional max temps.
It would be nice to also see the measured TDP with these charts: how much more power and voltage can be fed to the CPU under better coolers. I guess that's ultimately what determines the clock speeds that can be reached? And on that note, if higher temperatures need more voltage (and power) for the same stability, would be interesting to see how these CPUs could be tuned to perform on lower target temperatures. Though on the other hand, the higher the temperature delta, the better the heat transfer is, and that again means more power and voltage for the higher clocks...
I honestly don’t know what you are talking about. My 7600X with an air cooler (upHere P5K) and temps around 40s idle, not over 70 full load. I have not done anything except enable the XMP or (DOC).
I just got a Ryzen 5 7600 and it runs 50-60 C when idle/web browsing and 80-90 C when playing Helldivers 2. I tried to reapply thermal paste, lower CPU voltage, increase fan speed, still the same. I'm feel a little better after watching this video.
7000 series performance improvement is great but my 5950x can maintain all cores workload at under 68-70 in renderings and under 73 at gaming with 130W.

@@Azmodaeus49 Might as well do two useful things with that energy rather than just one. I mine crypto when it is cold. Why pay for heat and not get paid a little back? Or if you're gaming, you can reduce the thermostat since you're already producing some heat. Spring/Summertime and this system falls apart. Fall and it's back in business.
Hook both up to that thermal electric cooler(2,400 watts) that LTT made. What's that total with the 7950x and 4090? About 3,000+ watts? That'll heat a small home! 🤔😮
This is the video I've been looking for a long time. Like a did a week worth of research on whether I should pick AIO or Air cooler once I get a 7950x3D. Now I can be confident that a good Air Cooler like the D15 can perform on par with other good liquid coolers.
Well, I've just installed my 7950x with a Dark Rock Pro 4 aircooler earlier today, and at idle it sits around 45-50 degrees celcius.. Right after I placed my order, I looked around a bit, tempering my anticipation, and was slightly concerned that almost all of the builds I saw being done with that CPU used beefy AIOs, and people talked as if air coolers are impossible to even think of using with it because "oh noo it'll throttle!!1one"..
But it works just fine. Sure when I load the CPU as heavily as I can, it hits the 95 degrees, and there is a drop of about 85hz (maybe I was a little lucky in the silicon lottery), but that's synthetic load testing.. 20 minute hammer test, which doesn't at all resemble the heaviest stuff i'm doing myself, which is at most around 5 minutes of heavy loads here and there maybe up to 10 minutes, and that doesn't even bring it to the throttle point, at most it hits around 80-85 before my actual work loads are done, and usually I'll start those and walk away to do some dishes or something, so by the time i'm back to review, it's back down to the 45-50 degree idle temp again, ready for another run. I'm well satisfied with the 7950x on air so far.
That got to be a bit of a longer comment than I intended.. anyway..
TLDR: big beefy air coolers work just fine all the way up to the 7950x, provided your workloads aren't long you won't even get to the point where you could feasibly 'notice' throttling :P
(My heavier workloads are mainly some occasional molecular/atomic simulations, lighter workloads being BLASTing some DNA/RNA sequences - I suspect video editors especially might want to plan cooling solutions for longer workload runs)
Honestly, I got an AIO but it was only so I could mount it on the top (as exhaust). I know it's probably not helping my CPU performance much, but what it does do is it takes all the heat from the CPU and sends it directly out the top of the case, so it doesn't heat up anything else in the system. Which is still probably a very marginal benefit, but it's something.
Man, I Love your Speakers!! What Brand/Make are they??
Great subject and it was so well explained. Thanks for the video.
What about air cooling and eco mode 105w? For those who dislike watwr cooling.
Great video. Shows the comparison between the cooling solutions and puts it into perspective. Good stuff!
Beautiful methodology, data visualization, and presentation
My 7600 idles at around 70C and gaming stays at 95-96C with the stock cooler. At first i was worried until i did more research. I knew they ran hot but not that hot. I knew 100c was bad. I'm undervolting it tomorrow and I'm getting an AIO in about 2 months. I want to get one with a temperature readout on it. The last one I ordered, I saw a great deal, I'd been drinking, and ordered one with only intel mounts without noticing. Yes, I could have ordered mounts for it, but I'd rather just get one that I know the mounts are going to work with because it came with them.
No, no need to undervolt it if ur already getting an aio bruh
My 7800x3d is chillin at 65-70 with an air cooler under max load. mid 40s in idle
Finally a based video reviewer who doesn’t suck the shit out of intel CPUS
As an owner of a Ryzen 9 9950x and using an Arctic Liquid Freezer II 360 AIO, I can safely say that this chip runs HOT even at idle...You're talking 50-63 degrees almost constantly as an average. Then when in games (depending on the game) it can average anywhere between 75-83-ish degrees. Then in 3D rendering it lingers around 89-93 degrees. I thought at first that maybe I simply misplaced the CPU AIO pump a little, but no...they're just REALLY hot chips compared to Intel. Also, I use MX-6 thermal paste (spread method) and run my chip at stock 200W.
It was exactly the information I wanted to know. Thank you.
Fantastic video. I've never been a fan of AIOs so I brought my Dark Rock Pro 4 forward from my 3900x build to my new 7950x. The very minor loss in performance on extremely heavy workloads is fine by me.
The only other thing I wanted to see that this video did not cover is how long it takes to return to a baseline temperature after being on a max load for a sufficiently extended period of time.
The last few minutes were gold. Real world benchmark is the GOAT. All that stress test thrown everywhere from HUB to GNexus made people feel like they were going to be burning their house with these cpus on an air cooler. My AS500 Plus is going to rock this bad boy.
Lol. It will be dead in a year 🤣
@@timothygibney159 🤣
Very good test. Looks like I'm gonna get a 360 AIO and upgrade the fans to the Phanteks T30 to keep my Blender renders in check.
However you left out one question: What about undervolting? Does it reduce temps?
Yes it can help but 95C may be hit anyways just at higher speeds, you also do have the option on most boards to override the 95C temperature target. For example you can set your board to a target of 85C, which will result in a small performance loss obviously, but for extreme sustained workloads may be worth it in terms of performance per watt as well.
My personal plan due to working in a sound sensitive environment (music studio) is to manually cap the fans at around 40%, and set the temp target to 85C. In theory the PBO should take care of the rest and find the frequency that works to achieve that fan speed and temp balance.
tl;dr you pick the temperature and the chip will ramp up until it hits that temperature. CPU cooler decides raw peak performance rather than the temps as the temps will be the ramp target.
Most fan curves are based on temperature. Doesn't this mean that most computers are going to be running their fans at max regardless of the current workload on the CPU?
Exactly the video I needed. Thanks!
i sit here with my 5700x, running at 25c at the moment, doesnt get any hotter than 45c when gaming or in cinebench.
I figured the CPU would be running at about 60-70C while gaming and nice to see i'm not too far off. I hate when all the reviews mentioned about thermals and all they did was test underload with cinebench.
I then saw pauls hardware review where he took different coolers and found that the cpu didn't care. He then showed using PBO and applying the most aggresive setting, it lowered voltage, temps and raised the clock a bit more.
When i get my 7000 series, the first thing i'm going to do is voltage tune it or use PBO
Who doesn't use PBO on an AMD. It's a given
What is PBO ?
What I do not get is why do you need to run PBO to get the best out of the CPU? AMD shouldhave optimised the CPU out of the box to run at it's most effecient. Yes for a certain group overclocking and undervolting is a big thing but boy are these CPU's running a bit hot...
@@vMaxHeadroom Because it's considered an overclock which may reduce the useful life of the CPU especially if not cooled well.
And it's even better with undervolting and some motherboards integrated temperature limit options... 👍
The temp difference between AM4 and AM5 surprised me. I thought the pc would shut down at high temps.
This video has calmed my nerves. All is normal. I have a 360 AIO on a 7900x3d.
I need an air cooler for my Ryzen 7 5800x. for AAA games. and from this video I will guide you which ones could be used... if it does not reach 90 degrees and the pc freezes, it does not turn off automatically as they say.
Great video, and I know it's a little old. Just got my first rzyen CPU. I wonder if there is really an advantage to undervolt the CPU for max'ing performance?
You are a strong person in explaining. Thank you for the information. I will buy one soon. Thank you
I hope the 8000 series doesn't accommodate for older coolers with artificial Z-height in the IHS. That and adjusting the values in the curve optimizer should give the respin lower temps with more boost headroom.
Mh 7900x is always at 72 at playing games is that ok with 360mm aio
mine is roughly same , sometimes going up to 80 but seems like its fine from research ive done
Need only takes 2 clicks in the bios to make it cool and fast. Curve optimizer -30 or as much as your processor will allow and lock the temperature at 75 degrees.
What about a 4 hour gaming session or a 8 hour weekend session? will the CPU go to 95C after that long?
lets assume amd made these to run at 95c, what about rest of the motherboard and components on it, theres ram, theres nvme drives, even vrms and everything close enough together to be affected by something heated up to a boiling point. everything runs quite warmer bcos of this. somethings gotta give.
It doesn't actually PRODUCE any more heat. It just manages it poorly
@@HardwareCanucks it being unable to push that heat efectively to the cooler means it is that hot in that socket and all surounding area. It may not produce more heat but is unable to transfer heat away wich ands being the same
@@HardwareCanucks lol
Uhh.. would’ve been cool to see some comparisons between coolers made by more than a single brand.
It's coming! Needed to establish a baseline too!
If you drop the heat spreader, you can drop the temps..
I wonder if the 5000 series would be able to run with the 7000 series boost algorithm safely
It has exactly the same algorithm.
So the Optimum operating temperature is 82 deg c ?
Would it hurt the shelf life of AIO or cause water leakage, to have close to boiling water, example 95 deg c water, fluid flowing about in the rubber or plastic tubing and pump head ?
i just wanted to request gaming results :D thanks for that. This realistic scenario isnt really mentioned anywhere.
Makes me feel better. Rendered only a 2k video on a 7900x today and saw 81.4c max. Thought it was high but guess not.
@@NajiSibin thermaltake TH360 ARGB sync liquid cooler.
@@NajiSibin yeah I thought it was. Thought I built a hell of a machine but got scared seeing the temps. But again all good I think after seeing this. Can’t believe they have a max of 115°c
