- - I hate to say it; but stock Skylake CPU heatsinks are CHEAP! Regardless of the drop in total TDP from Haswell, cheaper coolers = higher temperatures, and higher temperatures = a saddened Greg. Let's dive further into this matter...

"It's about 5 more degrees, still nowhere near the Tjunction, and we can save a buck or two per unit."
"Dammit Johnson, you're a genius."
That's exactly how the meeting at Intel went.
True. It sucks that you can't overclock on a stock cooler, unless you have a super low-end CPU like the G3258 :(
ECCENTRIC
Well you can, buuuuut.....not a whole lot compared to something more beefy.
I imagine that 5 degrees equals 100mhz+ before throttling... Would be VERY VERY interesting to actually know this!!!
Meanwhile, AMD is making their badass Wraith stock coolers.
At least have a selling point if their CPUs are nowhere up to par.
Still not gonna buy amd until they actually make a cpu that can compete a i7-6700k. Waiting for zen
Xamnition I wouldn't hold my breath on the new architecture being a threat to current or even older gen i5s and i7s, they have a huge architectural disadvantage and much more limited funds.
It would be nice to have competition again, like in the Athlon days, though.
***** Im going to buy the xeon e3-1230v5 and overclock it in the next week or so, im not going to get a zen cpu in a couple of years
i am not sure if zen will be able to compete with current i7 on par, but probably will get much closer than an fx could but at a lower price than the i7, offering an even better $/performance ratio, like the rx 480 does.
So AMD release far cheaper CPUs of nearly the same power, and include a wraith cooler. Pretty much equivalent of a hyper 212 (but it's something). But Intel charges super premium prices, and still tries to cut corners on their own cost without reducing the consumer price.
And people hate on AMD so much.
Hmm
+Mario Saltalamacchia Actually no. Its not the nanometers that matter but the die side. AMDs die sizes are bigger and take much more money to produce than an intel counterpart. Intel cpus (correct me if I am wrong) are actually cheaper to make than AMD ones. AMD cpus need more Silicone wafers to make the same amount of cpus as intel cpus. Intel cpus are cheaper to make and they still charge more.
+Nissan U. (SUBW00FER) You are correct that CPUs with smaller die sizes are cheaper to make, but that's not the only factor that decides the price of a CPU. Since Intel CPUs are usually faster than AMD CPUs, it makes sense that they would charge more. It's the same reason a core-i7 is 100$ more than a core-i5. Even though it doesn't cost Intel anywhere near 100$ more to produce an i7, it's more expensive because it's faster. Also chips made with 14nm transistors will be more expensive simply because it's a newer technology.
+il2xbox Because someone needs to pay for that Huge Research and development bill that Intel has. 14nm doesn't just appear out of thin air.
JRBricha
Correct, that's why newer technology is more expensive.
You do realize that a desktop i7 is EXACTLY the same CPU as a desktop i5 just with hyperthreading turned on, right.
Its not like an i3 that IS an i5/i7 with defects, letting intel disable 1/2 its cores and sell off otherwise flawed processors nice and cheap. And when they can enable HT on a crappy i3 why won't they enable it on the i5. Intel is just greedy and their effective monopoly means this will never change. AMD is unlikely to ever have a modern day equivalent to the intel-bustingAthlon64/X2 these days. Intels anti competitive practices of the past hurt AMD so badly that they're never going to be able to get that performance crown back again.
You can't compares different coolers without precise CPU fan speed control.
The fan on the Alum cooler @4:41 ran at ~1650 rpm, while the one on the Cu+Al cooler ran at ~1400 rpm @4:35.
Fix that fan speed, either with an external fan controller or some software then we can talk about benchmark.
hereiam2005 The aluminum heat sink dissipated significantly less heat despite its marginal fan speed advantage. I suppose you think you're being clever here but you're actually being pedantic.
Nope, that is exactly how you compare stock coolers. I mean, how many people will use a fan controller to fiddle with a stock cooler? It doesn't make sense. The stock configuration is what most people will use so I think it's only fare to compare them without any modifications.
He predicted the core I9.
Michael mu. No duh it was going to happen sometime it was just a matter of when think about 3,5,7,9 it just makes sense
i predict the core i11 then
About time for i13
@@rogehmarbi I10 before 13
Hah
They have been flip flopping between aluminum and copper since 775 socket, it just depends on how hot the CPU runs if they decide it needs copper or not.
+Frantisek Bernasek any heatsink I've seen has been solid once piece aluminum or copper colored copper center slug in the aluminum
+Frantisek Bernasek oh, I'm talking Intel branded stock coolers only
I've got a pile of old Intel heatsinks, they're all copper core and one is solid copper including the fins.
copper or no copper that heatsink suck either way
lolz
true that
If you're not overclocking, it works just fine.
Agree.... thx to Greg and his "Intel skylake 650$ build" vid my bro succeded to OC his 6400 with stock cooler to 3.5 ghz. Weird but works just fine.
flowergreeeeed
What temps does his cpu reach at max load?
IMO non K CPU should include good CPU coolers. But K CPUs should not include stock coolers at all and drop the cost down.
The only thing that would really pull me in any direction when considering a stock cooler is like when AMD basically did a redesign admiting "hey, our old coolers sucked, we know, look how much better we're going to do!"
Boy am I glad I went back on my plans to buy a skylake this year. I've been waiting for 2 years to upgrade, now I'm thinking it might be best just to wait for Zen, fuck intel and fuck their prices.
+Cestarian Inhabitant If the temperatures are nowhere near Tj max then it doesn't matter at all. A few degrees is nothing, and it won't actually increase the temperature of your system by anything either. All it means is the CPU is a few degrees warmer, but it won't produce or radiate *any* more heat because of that. Everything else will be the same temperature, and the cpu won't lose any performance either.
I think everyone should be able to afford a great air cooler like the 212 evo. Best part is it can be reused for your next build, and your next build! Worst case scenario you may have to one day replace the 120mm fan.
Some kind of 92mm 212x would be cool and quiet enough for locked processors, as 120mm is a bit of overkill and very unsuitable for small from factor builds.
+tshepp89 mounting hardware changes and gets lost. socket 115- has been the same for a long time but not everyone has a processor from that lineup.
+Skooteh True, but with the compatibility of coolers like the 212 Evo, I dare say it would mount to the vast majority of CPUs out there. AMD or Intel. It suits like 5 generations of Intel so far.
tshepp89 I said that, it's just that peoples (myself included) lose older mounting hardware. It also won't likely be compatible with a socket that comes out after you buy it (like zen).
+Martín Varela You mean the Hyper TX3? It's the same general shape but smaller and with a 92mm fan, fitting into budget-oriented cases much easier.

Thanks for the support!
I must say, I discovered your channel by accident, but I'm glad I did! These are very high quality videos. Keep up the good work bro!
I am honored. Thank you!
Greg ma nigga whatchu gonna do bout that hair?
This is an old video, my man!
Still old. Channel started eight months ago...
It's thanks to all of you!
Eight months ago sounds too soon.
Feels like it's been a long time.
This is what happens when you dont have competition.
Nice video man! Like finding jems like you on TH-cam!
Awesome video! I didnt know that they switched the stock cooler! I subscribe to tons of computer tech channel and not one of them mentioned this change and the effects it has. Im glad you covered it!
I appreciate it! Thanks for the view.
Have you ever use an AMD heatsink? Fucking thing sounds like a turbine engine in my room.
Yes, I have. In a recent build, actually.
BlackSn0wz yes and they use standard fans that you could swap out and the wraith cooler is not that loud
not only that the coolers are getting thinner every generation, look at the old 775 stock cooler compared to the 1151 cooler
Exactly!
+Science Studio This video made me dig out my 775 stock cooler (q6600) and damn the copper slug is massive compared to these...
+Baumy 15
There was no copper slug in my E8600 HSF :(
the smaller transistors on the die also create more heat per nm and with a smaller overall die that equates to a bigger heat output, intel need better stock coolers for their chips. imagine if you could buy a 6600K or a 6700K with the LGA 775 cooler, you would have goodish thermals and some overclocking headroom
I have a Pentium 4 (LGA775) stock cooler and a first gen i5 stock cooler. The P4 cooler is massive, while the i5 one is basically the size of a Haswell i3 stock cooler. Both have copper slugs.
I've got an old i7 intel cooler that looks significantly taller, and appears to have a solid copper cylinder in the middle unlike the copper bowl commonly seen.
Keep up the great videos!
They probably went for a cheaper cooler since Skylake has also a better thermal interface, so they will run a lot cooler than before.
The copper core was probably implemented do to pre refresh Haswell CPUs having a horrible thermal interface material between the die and the IHS. My 4430 (lowest clocked normal power Haswell i5) reaches 100° C and throttles on the stock cooler on Prime 95 Small FFTs and around 87-90°C on CPU-Z's stress test.
Isn't cooper a better heat conductor than aluminium?
Yes, and has better heat dissipation properties. It's why any well-built graphics card uses nickel plated copper, not aluminum.
Science Studio Oh cool, thanks.
you should be able to look up the conductive (both electric and thermal) properties of metals easily. this goes hand in hand with your finding and its easy to see why they make heat pipes out of copper and not aluminum or alloys. Once I get a lathe I'll try my hand at making my own CPU cooler for shites and gigs #212EvoFTW
I still dont get why it matters in this case tho, as the fins are still aluminium :(
It also depends on the size of the cooler, not just the material.
this is really useful! great video!
Back in LGA775 days, copper cores were very common. I find even the Haswells overheat with stock coolers if you max out 3 cores.
you said it yourself, its not just about saving money, its about not wasting money. the cheaper coolers are still more than enough to cool these locked cpus.
Not on tropical or desert environments.
Martín Varela if you live in those places you are part of the worlds small minority, and then you get the burden of either getting ac, or a new cooling system for your cpu.
+JamesMichaelDoyle India, Australia, mexico, north of Argentina, I dunno... maybe WHOLE BRAZIL you genius.
Martín Varela oh really?
The climate of Brazil varies considerably mostly from tropical north (the equator traverses the mouth of the Amazon) to temperate zones south of the Tropic of Capricorn (23°26' S latitude). Temperatures below the equator are high, averaging above 25 °C (77 °F),
omg! that's sweltering heat alright! you realize that Ottawa, Ontario, CANADA summers are in the mid 30s?
get a grip bud. only a small portion of the worlds population lives in the extreme heat. linustechtips regularly have shown stock coolers performing adequately with ambient room temperatures at 80ish F.
and once again, if you are one of the minority that lives in these areas, invest in an AC unit. will keep your room cooler and more comfortable, and allow your stock cooler to do its job. its not like you are going to OC these LOCKED cpus.
+JamesMichaelDoyle I live just below of Brazil (misiones, argentina) And I get 37°c peak on summer, so no, you don't feel the pain. I can't just trow 600USD just on AC, because that's about what it costs here.
Not sure why anyone would downvote such a useful video.
People on auction sites often give their stock coolers (copper) away with their i5s and i7s when they sell them. I got my copper stock cooler for free with my second-hand i5-3570k which I run at stock clock speed at the moment on a H61, good to know the copper makes quite a difference.
Thanks for watching and appreciating the content!
Have you seen the old LGA 775 stock coolers for the Pentium Extreme Editions? It makes the copper slugs on modern Intel stock coolers just look like sleeves. They are also double the height!
Yea my Xeon 1231 v3 came with a copper stock hs but someone else I know they had a aluminum one sent with theirs...Weird..Another good video man, love the channel
It's because skylake TDP's are lower than haswell
Copper has a higher thermal conductivity and emissivity than aluminum, and so is used whenever aluminum is insufficient for thermal management.
I said that in the video.
Science Studio I typed that comment before I finished watching the video, probably should've waited before commenting.
All that matters is the final TEMPERATURE, unless Skylake somehow has a longer life at 5degC higher temperature which I doubt.
And of course FAN NOISE will be increased using the same profile.
What about how they gave a copper cooler on a locked cpu? Intel and their money.
You seem to be seeing what you want and ignoring what you don't like. The skylake processor runs cooler needing less cooling. You gain 5c of cooling with the copper block, but you don't need it. So, with intel wanting to save a few bucks, they went all aluminum. Where, with the haswell core, it was required to have a copper slug to keep the core cool.
I’m more surprised by the fact that stock heatsink is still a thing. I believe they shouldn’t include a cooler at all, especially in this class of CPUs. First of all, let's be honest, the majority of people who buy an all new Skylake i5 are not on a tight budget; they would have bought Celerons and Pentiums instead. Also, even a lot of those who are indeed on a tight budget are going to throw away that heatsink anyway and use an aftermarket one from a previous build if it’s compatible. Finally, if heatsink was no longer included the cost would drop for all even those who can’t afford an i5 but have a spare cooler. Then everyone would buy the cooler they can afford, depending on their needs for gaming, quiet mode etc. The current situation, where most people just throw away the stock cooler the moment they open the box, is inefficient, waste of resources, waste of money and “eco-unfriendly”
Interesting take, though I'm fairly certain these stock coolers only cost Intel a few dollars at most to produce apiece. Removing them from boxes will not reduce the price of the CPUs themselves by very much at all. And besides, they do work. $20 for a 3rd party cooler is still $20. It makes a difference for some. Additionally, most people don't have extra heatsinks "laying around."
If you are on a budget, go to ebay and search "tower heatsink", you can get them for about the same price as a stock Intel heatsink which you can then sell.
You only keep a stock cooler when you can't be bothered to do an upgrade.
I just love your videos. I just wish you had more subscribers for how much work you put in for each video.
+King | GoofyMC Share his videos :) he's on the way up, just you wait :D
If people are going to be re-using their liquid cooling setup, then Intel is pretty much throwing away a fancy metal slab for each one that is not used, meaning 'money lost' giving consumers stuff they don't use.
Also, in the last 10 years of people buying and getting 'cheap' stock coolers in every 'package' that was sold back then, how much copper is actually sitting in people's homes, garage, basement, closet, unused?
no. for intel cpu's you can choose to buy a "box" version with a cooler or a "try" without.
+yakir11114 I think you meant "tray" and not "try".
How much cheaper if you buy a cpu in a tray without the stock cooler lol?
an insignificant amount is sitting around. also, the price of those mass produced would be pretty small after selling the CPUs, but cutting down even a dollar over millions of units obviously makes a difference to Intel in the end.
melt down those back into copper and aluminum alloys, sell them for a better profit... Especially since you can find them almost everywhere.
4:08 Intel core i9 predicted
Hi
Just the kinda video I was looking for! I'm planning a ghetto mod on a GPU heatsink, but I'm gonna test it on a stock CPU heatsink I have laying around first. Nice to see the difference a copper slug makes in the temps, hope I can successfully attach a copper plate into the heatsinks and see lower temps and noise levels.
while building a streaming machine for my room i also took notice of this 'all aluminum' bs. still had an i5 heatsink with the copper slug saved somewhere so i just popped the fan from the i3 onto the heat sink from the i5 stock cooler and called it a day. seems to be working fine so far.
I don't really think it matters as the temps are still completely fine.
Intel has always been making coolers that are enough but only that. I actually wouldn't care if I would buy a new processor and I would install the new cooler instead of my current one that has a copper slug because of fan life. :P
Don't forget though.. cheaper CPU because not a k SKU, no aftermarket cooler needed and you can use a cheaper motherboard that doesn't have overclocking capabilities but exactly the same or close features and that could save 100 euros or more where I live.
The price to performance for the k SKUs isn't really adding up where I live. :P
much ado about nothing. If it's a sufficient cooler, it's sufficient. You're not going to be overclocking with a stock cooler anyway.
likewise, it's definitely based on TDP, which he only mentioned in the description, unless I missed a quick mention in the video?
He mentioned it at 1:07, but it was kind of a casual throw in, so I can see how you would not notice it.
You keep forgetting how loud and obnoxious these piece of crap can be
It's about the consumer losing out. Skylake K models don't include the stock coolers anymore but they are still more pricey, even more than Haswell before it. Now if we get stock coolers with the non-K models, we get flimsy all-aluminum coolers that came with CPUs that are just as dear as the Haswells that came with the aluminum + copper coolers.
the jews did this
Hey, great vid. Good info, I have a spare "older" intel heatsink from my i5-4460. Since my brother is building a new PC with a non-k Skylake CPU, it's good to know that I should let him use my copper cooler and he can ditch his all-aluminum. Thanks!
also check out the fans and the amps on them... the g3258 had a nice heatsink and it had a delta fan :) others use nidec servo
Meanwhile AMD is stepping up their stock cooler game with the wraiths. Hopefully Zen will deliver. I'd be willing to go to Zen if they offer a full blown 8-core with haswell level IPC from my i5 4670k.
100% agreed. Would be worth a shot.
+Riley Nelson my next pc is going to have zen regardless (well unless its another vishera...) im so eager to see ow they perform and hopefully intel will have proper competition
I thought skylake didn't come with a heatsink??? Intel sold one seperately, but for the price you could buy a Hyper 212 Evo from CM.
Edit: NVM Turns out only K skus don't come w/ it.
Correct.
Skylake non "k" and xeon cpus have a stock heatsink
who uses stock heatsinks, seriously?
Harry Lawton I mean, I want skylake, but not the noisy stock cooler, so 212 evo here I come
my friend
I got a 3 heatpipe beast of a heatsink from an old HP office PC. Mounting holes have changed, so I had to get creative and use small zipties (yellow, to match the accents on the motherboard, lol). Got a bunch of the old intel ones with the solid copper slug that are also tall, too. The crappy all alu ones I sell when scrap alu prices are high.
I have an old silver dollar that's worn smooth... I'm wondering if I could put this between cooler and cpu +thermal paste and if it would transfer heat better?
a real tech channel unlike LTT
+patrick Tighe LTT would of spray painted the heatsink to a copper color...LOL
+Karishin32 lol got that right
+Mario Saltalamacchia You'll find that most never even noticed the stock cooler change. So you're welcome.
this vid is top notch 👌
havent finished watching the video but i do remember something about how different metals often dont like to play well with each other, with one causing the other to corrode much more rapidly than the other, maybe this is why my old P4 copper core heat sinks seem to all have brittle aluminium fins, while my even older P3 heat sinks still seem relatively solid
+denvera1g1 its funny to say that intel is doing this to save money, because their CPUs cost less to produce than AMD CPUs, really they are making money
+denvera1g1 i can see the thinner fins being an advantage over thick fins IF there were more of them, but there aren't
Subbed
Appreciated.
+Science Studio loughed
Not a word which describes anything in this context.
Science Studio k ;(
Intel is becoming a monopoly, hopefully AMD will will this year
Very prescient words 👍
Hey, that display looks familiar... Is it LG 29UM58-P?
And this kind of thing continues nowadays. The i7 8700 (non K) comes with an all aluminum cooler that completely fails to keep that cpu cool without throttling
Who uses stock heatsinks anyway?
majority of people
People who don't use their system for heavy gaming/rendering.
Who even uses heatsinks in the first place?!?!?!
people who dont use their systems for heavy loads won't even know about the CPU temp and wouldn't actually care either way. People who care about CPU temp will be more likely to be overclocking etc and should NEVER be using those stock heatsinks anyway. Hell the latest CPU's dont even come with one!
In Australia the the unlocked skylakes dont come with a stock cooler. At least where I got mine
*What is the stock heatsink one gets with i5 9400f?*
Also though, various heatsinks have different fin configurations. My locked Haswell 4120 has an all aluminum cooler with different fins than my 4790k stock heatsink. Not that it seems that the stock heatsink will be used on the higher end cpus.
Not just thinner fins of any sort, but different patterns. One of them has forked fins, the other has spiral looking fins.
I am using a Core i7 6700, with cooler master CM103 cooler, in benchmarks, my temps go as high as 75C, is it too hot for sustained load? My ambient temp is around 27C
I Really didn't think that a 65W TDP cooler will generate so much heat as to require a decent cooler.
Good work ....
i have a question that.... i want to purchase an i5 6500 skylake with my Nvidia GTX 970 gigabyt G1 gaming.... which cpu cooler should i use for i5 6500 skylake?? either the stock cooler is enough or i should get a new one????? but not expensive ... please guide me. thanks in anticipation
yes it was nice that it was settled this matter. I have always wondered if the new generation CPU cooler cools better then the old gen in the bottom of my trash can were both of them share the same place right now. on the other side last time some one did use the stockcooler for anything other than a bookstand was when Elvis was still alive
Depends on what socket you have... some aftermarket cooler like the cm hyper 103 are quite cheap
I am using a custom cooler now. Actually not air cooled, so it doesn't apply, but when I first got my intel core I-7 4790K 4.0GHZ "Devil's Canyon" it came with a cooler that had a copper slug in it, but I also didn't realize it came with a cooler at all when I bought it because I bought it online from Newegg, so I had gone on Ebay and bought a cheap Heatsink which did not have that copper slug. I had also swapped them out and tested which one was better and I got similar results to yours. I have no idea why, but I was somewhat surprised. However the system was not as cool during multitasking, load bearing chores such as Streaming and Gaming while recording or rendering animation. With the stock heat sink it was getting up around 90c so I bought a pump, some radiators some heat sinks for water cooling and some radiators, fans etc. before even thinking about overclocking it. if you are just gaming, video encoding, etc those stock heat sinks are fine, but if you choose to overclock. Get a custom cooler of some kind, preferably water cooler or at the very least a double cooler like the Noctua Dual Tower CPU Cooler for Intel LGA 2011-0/LGA 2011-3 Square ILM/1156/1155/1150 and AMD AM2/AM2+/AM3/3+,FM1/2 NH-D9L on Ebay. I think I bought one for $54 and ran it for a while before saying "Nope" not cool enough, around 70C but I was able to clock it from 4.0ghz to 4.5ghz on this cooler. and it still stayed around 90c on that tower overclocked to 4.5 Now I have acheived 4.7GHZ on it and it remains at 40c under heavy loads, but intel claims you can achieve 5.0GHZ. I get a BSOD after 4.7 so no overclockie for me me after that, but it could just be the outrageous amount of power needed to run it or maybe it is not cooling down enough demanding so much from my power supply or some other hardware problem or liit preventing it from working. because the BSOD specifically says ACPI, I am not really a Hardware guy as far as pushing the limits goes, but I really don't notice any differences between 4.3GHZ and 4.7GHZ, It's never under that much of a load constantly to make that big of noticeable difference. Out of curiosity, I would like to read what other people have found on this particular chip. primarily because this is the chip I have. I know it's not the greatest anymore by far, but Curiosity calls and these chips are pretty common, so I am sure someone else has had an experience with them. Has anyone ever gotten it to 5.0GHZ without a BSOD? What cooling system have you used?. for me.. I don't really even need it at 4.7GHZ because like I say I find it adequate even at 4.5ghz and haven't really noticed any real stability issues or differences in performance between the two speeds. But also as I say I am extremely curious if anyone has ever done it because Intel says you should be able to get it to 5.0GHZ on air Cooling.. So.. It must be possible right?
I love your videos and I think you deserve more subs than you have keep the hard work.
Thank you! I'm glad you're enjoying them!
i bought two 4690k I5's and 1 came with a copper slug the other didn't which had me very confused... didnt matter i was using a aftermarket heatsink, but i was still curious as to why intel would ship 2 variants of the stock CPU cooler
At 4:40 I noticed that with the aluminum-only cooler you not only had higher temperatures but also significantly higher CPU fan rpms and thus more noise generated.
This is one of your best videos, Greg. Keep em coming.
Thank you! Will do.
How about the noise diffrence between these two under load?
The Ivy Bridge(Core i7-3770k) stock coolers had Cu slugs and higher fin densities. If you go back to Sandy Bridge, the IHS's were soldered on rather than a cheaper thermal paste like the new ones have.
They've consistently gotten cheaper with their stock cooling.
Does that one Phanteks fan mounted in the top make any noise? Any clicking noise to be exact?
Cause those fan are known to make that sort of noise when mounted horizontally.
No clicking sounds or abnormalities thus far. I'll be doing it again in my Xeon build so we'll see if it happens next time.
Science Studio That's very nice to hear, thank you very much.
That's one of a kind video. I've been using Pentium G3220 Dual Core from 2015 & don't have the budget to upgrade to 12th or 13th gen so wanna just upgrade the processor to I5 4570.
But problem is that my Pentium has the all aluminium heatsink & I5 uses Copper one.
Should I go for an aftermarket cooler with 4570 or aluminium one will suffice🤔
I upgraded Pentium G3240 to i5 4590 with same aluminium heat sink.. Temperature maximum goes up to 67°c..
very interesting. thanks.
I just bought an i7 4790. Is it better for me to use something like a hyper 212 or will the stock cooler with copper slug suffice? Thanks!
Thank you for covering this. I thought I was going insane.
You should do a follow up testing if the new cooler impacts the ability of the CPU to Turbo up. :)
Maybe testing the 6400 with both coolers and see how it reacts.
did you do the 5050 kit for your PC also? :D saved me 100$, was able to use it on desk also, just noticed simple fade and wanted to ask
+wilson pies I'm not sure what you're referring to.
5050 led strips, much cheaper than a kit like NZXT hue+, or cablemod strips
Ah, yes. I used a Logysis LED kit. It's covered in my 6600K RGB Build video. I'm not very familiar with LED nomenclature just yet!
Again, nice video. Keep it up. I like your content.
I remember back in the LGA775 days my old C2D E6700 cooler was about twice as thick as the new ones and had a huge copper slug. it was actually a really nice cooler and was even good for some decent overclocking. I don't think I've seen a better stock Intel cooler in all this time which is pretty sad considering how much we pay for them.
I got the little tower Zalman 5X Performa for about $20 USD back in 2013. It still works really fine, and after installing it on non-K Skylake ( I didn't get the Box version because of the prices in Russia) i5 6500 I can't hear it without opening the case! And the temperatures are really stable.
Can you do a video focusing on the advantages of Skylake over the previous gen(s)?
I've already uploaded several head-to-head comparisons.
Point: Wouldn't thinner fins mean less mass for the heat to transfer through before the fan cooler can dissipate it?
so is the copper stock intel (a) better than a larger aluminum (b) cooler? (b) is about twice as tall as (a), does height make more of a difference than having copper?
I THINK YOUR THE FIRST THAT NOTICED IT, VERY INSTRUCTIVE VIDEO , KEEP ON I'm A FAN OF YOUR CHANNEL
I would be interested in seeing the temperature difference between Haswell's cooler on a Haswell CPU and its Skylake equivalents. If this allows them to run within a similar TDP envelope, I don't see the issue.
Also, as I understand it wouldn't the thickness of the blades have little to do with heat transfer? If only they used that reduction in thickness to add more blades...
+nunchucker An increase in blade thickness increases surface area, which accelerates heat dissipation.
On my computer the Heatsink fan combined thick copper rod from top to bottom is surrounded by aluminum fins
Able to cool down TDP86Watt CPU to 47 ° C when doing CPU Stress testing
Keep up the great vids :D
how do you handle the copper on aluminum electrolytic reaction?
Again, nice video mate. Maybe it's time to have a separate Testbench :D
+Muharrem Mungan Agreed :-D
+Science Studio cool that u taking advices from your subscribers :D and replying to the comments :D
The thinner fins on the all aluminum cooler may actually net more surface area to compensate for not having a copper slug....something to think about.
+Ron Garvin They don't, because there are exactly the same number of them on the copper-slugged cooler, which are also much thicker.
so in short copper heatsink's are more of having to cool the CPU better? than aluminum one? I've replaced my aluminum heatsink with a stock copper intel one's
it's worth noting that the haswell copper slug cooler is hollow on the inside. I popped the fan off and there's a thumb sized indentation.
+Golden Grenadier Yes, I'm aware. However, it still works much better than the all-aluminum one, according to my results.
+Science Studio I wonder if temps would be even better if the cavity were filled with metal. I'd love to pour molten metal into it and test the temps(after the metal cooled of course)
Great video. I have a leftover copper slug from my 1231 V3, I think I will give it to my bro when he gets his i3 6100.
Hi, I have 2 heatsink, 3cm tall with copper, and 5cm tall but no copper.
Wich one do you think would be better???
Thanks!
I have i5 6400 stock cooler just cant afford aftermarket right now do I need a aftermarket to keep it safe ive seen my temp at 60 while gaming
i wood like to know is there total coper cp cooler, i newer see it in my life. ty
While the thinner fins do make it easier to break, don't they also allow for quicker heat distribution/dissipation? After all, it's much easier to cool a thin sheet of copper with a surface area of 25 square inches than it is to cool a one cubic inch block of copper.
Thicker fins have more surface area, and thus more contact with air. The number of fins between both coolers is the same.
Lower TDP means less cooling required. What would be nice to see is what temps the haswell had vs the skylake with there oem heatsink & fan. But honestly aftermarket 30$ HS&F is the way to go even if only for noise :)
Yes, noticed the same when i built a pc for a friend a couple months ago, we ended up buying a 30€ tower cooler and it runs passively with the case fans being the only ones moving air thru it and it runs cooler than the stock one, but the aluminium move was kinda cheap from them, specially when they won´t lose that much amount of money if they put the copper cap instead.
I like this video because I been asking the question, 'Is aluminum a better cooling material than copper?'. I'm planning to rebuild my Vega64 gpu and they are notoriously hot running cards at overclocked temperatures. Therefore knowing which material used for cooling small vrm, mosfet and ram is essential knowledge. Good work, bud.
The Skylake processor I bought didn't include a heatsink at all (6600k). How did you get one with yours? Is intel including coolers with their processors again?
+Ryan Toomey My 6600K didn't either. Only non-K variants still come with heatsinks.
