Does Connecting Your CPU COOLER Directly To Your Case Fan Improve Temperatures?

- One this everyone battles regardless if you air cool or water cool is heat. Heat is the archenemy of the CPU, the cooler your processor runs the better you system will perform. There has always been one thing that I have wondered, how much does the heat inside your case affect your air cooler. If you were to pull only fresh air into your case and push it directly through your air cooler would that improve your cpu temps. Well you all wondered the same so I got to work printed out some adapters and ducted my cpu fan to my front panel case fan and the results were more than I expected.

I'm an HVAC professional with 20 years experience. Move all your slack in to duct to the entering air side or cut it out to remove resistance in the duct for smoother airflow. The resistance is slowing the velocity of the air. Hope that helps. BTW love your videos.
Seconded. I test extracts as part of domestic energy efficiency assessments and flexible duct kills airflow. Try making the duct out of printed sections that can be screwed together. Will be way more efficient.
Maybe if you had very powerful fans pulling air then your duct resistance would matter but it doesn't matter here lol

I approve this comment. I am an FBI Agent and I can tell you are surprised just by looking at your face. Yes, I'm looking at you from your camera
Spiral duct actually spins the air. The fastest flow known on earth is a tornado witch spins... but yes the tighter the flex the better and if you can seal the gaps were connections are made the efficiency will go up. Also insulating the exterior will help keep coldest temps
These cpu to case shrouds used to be common about ten years ago!
I came here to say that, I am glad other people remember that this was the hotness in early 2000’s
I was just about to say the same thing, i still have a few OEM pc's like HP's Acer's and Dell's from the late 90's early 2000's laying around that have the ducts on the side panel
I just bought an HP Proliant old server today and it had a very nice clear plastic shroud from intake to exhaust. Interestingly, it wasn't for the CPU, it was quite obvious it was to direct cool intake air over the RAM. I'd never seen that before.
yeah, mostly dell optiplex 360 towers... Were really quiet...
some OEM systems still use ducts. not directly attached to the fan, but the idea is the same
20 years ago: We'll connect the case fan to the cpu cooler
10 years ago: That looks stupid let's remove it
2019: BRING IT BACK AND SEE IF IT WORKS
every phones features today. add and remove and call it a feature.
@Justin Martone except the cost :/
@Justin Martone Cost, maintanance and reliability matter. I switched from 280 AiO to Dark Rock Pro 4 and it turned out to be a little bit hotter on cpu, but percieved noise is actually lower (and i switched fans for better setup on the AiO -> push pull with 4x 140mm). There's something for everyone.
@Justin Martone so.. gonna spend 25, might as well spend 250? Great argument lol.. if you want to liquid cool your PC by all means be my guest..
Not everyone wants to though and this is a relatively low cost mod with tangible benefits for those that would rather not
@Justin Martone just gonna put this out there th-cam.com/video/23vjWtUpItk/w-d-xo.html
Back around 2001, I bought a kit just like this, and used it to direct cool my overclocked pentium 4. :)
Was it a Socket 423? I remember my AMD T-Bird use to get toasty ASF

This used to be a big thing in the early 2000s with a duct in and a duct out so no heat from the CPU contaminated the case.
Duct system is still a big thing for brand-name workstations from Dell, HP and Lenovo as well as in servers. Almost all servers use a duct system in form of paper-thin plastic sheets which force air in a straight path over CPUs and RAM sticks.
Yes remember 2000s 😅
To think that the 200s were -10- 20 years ago
Yes, yes, and yes. This idea has been part of many designs. If fact I think the Mac Pros of even 2006 had a similar type of design. Enclosure pushes all air from the back, pulls from the front, while the CPUs have air directly pulled from the front and pushed out the back.
Who remembers the thermal take duct mod for getting rid of the dead spot beneath the fan?
it's cute when new audiences find out about oldschool mods :D
drunkredninja xkcd.com/1053/
Agree, and they aren't even mods anymore, some OEM's do this for decades in the prebuilds.
This is not even a mod. Servers still use ducts to redirect airflow.
I actually forgot about that shit. Thought it took up tooucu room why not vent it out the side. Much less space taken up. Especially since there's top mount fan coolers.
@@BrunodeSouzaLino uh it's a mod cuz it didn't come with the case you fucking foreign idiot lmao

That’s a rare insult for sure... if even an insult...
FYI: The old Dell tower has this out of the box
After all, p4's and pentium D systems, and their crazy 2 pentium D had the need to get every single possible cooling technique that they could.
@@eduardoavila646 I have a pentium D 925 and it is Super hot, the stock cooler doesnt keep up at all
@@tobyngenn9826 True, that's why dell, hp, acer, etc got those ingenious ideas.
Even tho they still heated alot with that, they could hold up.
Yup on Optiplex 320 , 330 , I think
I have a Dell Precision 490 on my workbench right now and it basically has a separate air chamber for both cpus and the ram with the front fan blowing straight through both heat sinks and another drive cage mounted fan blowing down onto the ram. I added two 80mm fans at the back to help with airflow.
I worked in PC repair store, and what I learned is that a lot of older cases had a plastic tunnel system from case vents up to cpu fan on the cpu cooler. It looked very professional, and created perfect pathways of air. That works amazing in a case, because there is no interruptions somewhere, and also the air exhaust tunnels on old PCs were basic but glorious. Nowadays manufacturers do a crappy job with air flow.
Run a duct from the bottom intake to the blower card and test that out. :)
This!
@@Moshenokoji Thanks! I just realized I have 42 likes. That's the most I've ever had so far in a comment. LOL
Good idea because warm light air moves upwards
I was thinking the same thing as soon as the video ended
Actually take 2 120mm fans and connect them to the one blowerstyle cooler. Why? It creates pressure so the card can get air easier.
Man, I almost cant describe how "cool" your experiments are! Keep doing things like this! Thanks;)
@2:24 -- Notice the line of tantalum capacitors...They all say 330 on them...except for one in the middle, that just says 30 @2:24

Man, you post some creative videos. A channel like this among any hobby is rare!
This is why I love this channel man, it's always very interesting.
I remember seeing something like this way back. I used to have a case that has grills on the side panel, right above the cpu cooler. The cases would come with an extra tube/duct that you can screw on to the grill so that cpu cooler can draw cool air directly from the outside.

Server CPU coolers use baffles to do this type of thing.
Sweet, I always wanted to do this so thanks for doing it.
I love watching the bump in quality with every video. keep up the awesome and innovative work my friend
Nice, I swear this came from a comment I placed for a friend of mine who refuses to consider watercooling because it would endanger his sanity and ability to sleep at night. His plan for his next build is to get an extra clip and have yet another fan on the rear of the heatsink and yet another duct from that to the rear exhaust so it’s just a complete “pass through the case” and essentially a wind tunnel powered by 4 fans. Anyways this video gives enough proof of concept to validate his premise, well done! Your mods are always interesting. Thank you for being so jank-dank!
I would like to see that when it's finished :)
OEM's have been doing this for decades, and in the early 2000's it wasn't uncommon to buy a case that had a duct from the side of the case directly to heatsink
My old Dell had a duct...it was green in color.
Before I upgraded to liquid, my mini-ITX case design worked on the same principle since there was barely any room left between the NH-D15 and the front/back fan, and it was surprisingly cool.
“Why no one does this?”
Because my case has good enough airflow. But we have multiple old high end winxp workstation pcs at my workplace, and those have air ducts on the side of the case for the stock top-down heatsinks.
But they are doing it, in workstations.
I had a case that actually does that. I liked the idea but it messed with clearance so I took it out. Unfortunately that also meant I lost the case badge logo as well lol
I use to do this with air coming from the window through the side vent in the summer. In the winter I would exaust it to under my bed
@@ArtisChronicles Antect use to do this
Its been done homie.
I feel like I'm the water cooled version of you, I wish I had a 3d printer back when I built my office water cooling system. Instead of trying to spend a fortune on a fancy watercooled case build I did external water cooling to ultimately dump the heat outside and go for function. I built a custom wood spacer that I wedged into my office window trimmed and sealed, then epoxied copper pipe through the spacer in the window with quick connection fittings on the indoors side. Outside I have a large copper transmission that runs the span of the window mounted horizontally. The PC dual d5 pumps, they pump to the CPU-GPU then to a PCIe passthrough plate, then it pumps the fluid to the top reservoir which is clear PVC pipe I bought online that I modded to my desk corner so I can always see the fluid level with a clear top cap. The fluid goes into this clear pvc pipe via a 3 way fitting under the desk level, a smaller 1/2 inch stand pipe is installed down the center of the pipe at a lever above the radiator outside. The output of this clear pipe exits out the bottom 3 way under the desk to the window connecting to the quick connect on the window. It passes through the radiator outside via gravity and back to the window. From the 2nd quick connect on the window it passes to the pc to feed the D5 pumps. I see temps as high as 41c with the outside fans off during normal usage web browsing and youtube viewing with it passive cooling the loop here in Florida. I recently added a relay circuit with waterproof automotive fans outside that triggers a relay at a set temperature to kick on fans. I have 3 small fans on the radiator that kick on 1 at a time based on temps. During streaming and gaming it will trigger 1 fan on outside and actually maintain temps in the 40c range while streaming and gaming.
My dad and I both did that years ago. My temps have been so good with newer cpus and heatsinks that I have not felt a need for it. It's a fun mod though. Used to go to Lowe's and auto parts stores to find more aesthetically pleasing pieces. Big old shrouds from 775 Dell pcs and such worked well also. A can of spray paint would make them look better.
Very clever, I often wondered what a custom intake design would do for cpu temps.
My very first PC case had a side duct, meant to deliver cool air on top of a stock CPU cooler. One of my older work computers (a Dell, I think?) had basically this exact setup, but with hard plastic channels. Also, the idea of cooling the CPU with cooler outside air is exactly why my current PC is cooled with an AIO set up as an intake.
Yeah but that way you're putting the heater air from colling the CPU onto all the other components in the case. Whereas is you have it on the exhaust all the hottest componenst put their heat straight outside keeping the whole thing cooler, admitedly with the CPU negligibly warmer.
Im glad this was in my recommendation
same here
Google suggested your video to me and I am now subscribed. Great video! Look forward to seeing more.
I'm happy to hear it welcome
Love that you're being inovative my dude, its refreshing

With a gold foil duct, this could be a moon rover build.
Would the foil be conductive?
@@jasonhemphill6980 That os conductive.
Is an acident whating to hapen
Thanks for sharing this was wondering the same. Also like your Mugen 5 CPU cooler 👍
I remember doing this with a Coolermaster case 10 years ago. The case used two 200mm fans, one on top and one on the side. The top was a general exhaust and the size side was ducted to the cpu fan/heatsink. If I recall, it was good for 10 to 15c after hours of max setting WoW. Liquid cooling took over after 2010, no further ducting development experience.
i have the top fan blowing air on rad as "intake fan" seem to get a way better lower temp this way,
but i have a 3x back exhaust fan on the back make sure it blow out all the heat inside the case, use the top fan to blow air on memory and VRM
then 2 front Intake 140mm fans, and one for the hard drives, and i put xtra one behind the motherboard back to the cpu back plate, it does help a little too. at the end of the day temperature is getting ridiculous low, as i speak my i5 3570k clock at 3.9 asus p8z77v i get 30 celcius all core.
now add this on top of it. and i don't even have a noctua fan, i use dual evo12 with artic silver 5 thermal past.
Arctic cooling value packs here I come
In the Late 90's Early 2000's most cases came with fan mounted on the side panel and you could get a duct that would connect from the side panel to the stock cpu cooler, we would get a extra duct , screw that on the outside and run some ducting up to the AC unit
-73 C
You are right! Now I remember those side ducts, sometimes with a Pentium or Celeron.
It's interesting to note the venturi effect created by the custom printed fan holding mounts have smaller diameter and open up to the other end creating a surge in the end which is exactly what we are aiming for. Great experiment!!
dude i love your crazy ideas lol keep it up!
When you're a computer enthusiast but also an HVAC technician
Everytime you post a new video. I know I'm in for a good time. Something interesting, & Extremely creative as well. Just like this video. No one is doing this stuff.
My only thought would be. To have the duck go from the front of the case. To the back of the case. That way the cool air goes in, & out. It will not mix with the air in the case. Thank you for posting this video. I can't wait for the next *Video. Have a great day.
Thank you for testing this. Brilliant idea.
This is basically what rack-mount servers use, I don’t understand why case companies aren’t doing this. Awesome vid!
You may want to try 2 fans at each end of the duct for a push/pull configuration. It works on large RF amplifiers.
It's what I did with My PC, dropped my cpu temps by almost 20 degrees.
0:48 Ah yes, the Printed Circuit Board Board
Thanks for making this. I've always wondered about this. Mystery solved! I want to do this someday.
I like your craziness ideas bro, glad to be one of your loyal fans
they had cpu cooling kits like this back in the early 2000s.
“Why no one does this?”
i remembered thats why BTX business units
That is very interesting, I would appreciate longer testing with a high tdp axial card. I run a r9 fury nitro and a 7600k @ 5.2 ghz, the only real reason for me to use an aio is the fact that my gpu brings the air temperature to above 40 Celsius, easily. I think a setup like this with a intake dedicated to the CPU on he top front would look a lot nicer than the one in the video and give better results than my ML 240 lite.
I was thinking to do this and searching whether someone has already done or not, and finally found this video... thanks 😁
This is basically how servers in a rack do it. Straight from front to back airflow.
This way, you’ll miss cooling on the vrm’s and RAM from the front and cpu fan. Maybe in the next test measure your mobo temps to?
I did this myself over 10 years ago but this was for an enclosed rack server that was making the small room that it was in warm, there was an xpelair fan unit mounted on an outside wall, but it was not working, so we installed a new large faster model and ran flexible ducting to the output fan shroud on the top of the rackmount case and a large 20" industrial fan at the bottom of the case and we managed a 10 degree drop in server temperatures.
When the office heating went out on a cold and frosty winters day we directed the hot top outlet into the main office and that did a good job of warming the office up, till we could get the heating fixed.
I seem to remember once seeing a mainframe or server being directly fed with cold AC air to get a reduction in operating temperatures, I am surprised that you don't see a home brew version of this, unless someone is already doing it.
Not only this is actually an oldschool cooling method (I think back in P4 or C2D era), but rackmounted servers today still uses the same method of a dedicated duct or air path to force the flow of cool air into the heatsinks or hot components. The different is on server environment they use a very high static preassure fan (that so damn loud it sounds like a jet engine) since noise is not really an issue there.
Get a cpu cooler with push pull and continue that duct right out the back
Right off the bat I'm going to say I prefer the 4K quality better.
Agreed
2nd thing I have to say is that would be DOPE with hard ducting.
Well, I did this with my heavily overclocked Athlon Thunderbird C back in the day. It Ran at 1600 MHz with an 200MHz FSB. During Winter the case fan had an extra hose going out the windows to suck in the cool air. did a great job.
In my prev company we had a IBM xeon server that had the CPU cooler completely seperated. It had a plexy glass tunnel from front to the back. It had a fan on the front of the case and another one at the back of the case. It was working very well, noisy but well.
I'm in the 4K clan, whatever the frequency is
Yikes.
I would prefer HDR at 1080p30
Why is no one doing this?
It's not as expensive as water cooling and no rgb... So manufacturers don't mention it
@Timmy P they can get their own vents with additional fans ;-P
I love that you bring all these ideas that have been floating around my head to life.
What else do you have floating around do tell I'll see if I can make it
@@MajorHardware Well it's gonna be expensive, but what about a full loop system in an open air case with zero fans. All passively cooled rads.
so you discovered the air duct ... that is cute, but been in use since the early 80's
7:53
Can be a good meme
It needs some RGB in the shroud
Cool video, man. I've thought about doing this before, but using this massive black 4" 3-ply silicone hose I've got, which is typically used for engine air-intake/intercooler setups. But I had about 9" of it leftover after working on my car, so I figured I'd give this a shot. I see you getting a lot more subscribers in the near future, within the next year or so. And then you'll have all of these companies sending you a bunch of free hardware to check out and use.
I hade a duct(hard plastic) from the stock CPU-cooler to the back of the case fan when I build my computer in an OEM case 10 years ago.
It worked really well back then, and it was easy to remove and insert with some clasps.
Interesting
Now your RAM isn't cooled, though
Nor vital parts of the motherboard (northbridge etc...) that can get very hot.
RAM does't really need cooling in the vast majority of situations.
@@AJDOLDCHANNELARCHIVE You only have to duct one intake case fan, so if you have more than one intake there's your MB, SSD and VRM cooling. Also RAM cooling, if you're into that sort of thing.
@@lastfirst5863 True to some extent, but I'd imagine the amount of airflow and speed of airflow over those hot components on the motherboard is going to be much lower with this duct going straight into the CPU cooler.
If you had a side panel intake you'd probably be alright, but those are out of fashion these days.
@@AJDOLDCHANNELARCHIVE Nah dude, I think it's true to all extents. Total airflow speed might be slower if you gimp yourself by one fan but higher airflow speed gets you diminishing returns anyways. Most cases have the exhaust fan and right next to where the heatsink mounts, so the air heated by the CPU doesn't have time to stick around and share heat with air in the case. That way you aren't compounding heat from all the components together inside the case.
I only saw one intake case fan on his setup which all his components shared. If he had two, I don't think MB overheating would ever be an issue.
4k at 24 is better
Way back around 2006, Dell was making cases like this with the Pentium D. It had a massive fan in the front of the case that sent air through a plastic shroud directly towards the CPU. It was a brilliant design and kept it very cool.
I like your style man!! This is exactly what I have setup for my AIO, where the side fan would normally be I have ducting going directly to the CPU rad. I took a failed 120mm fan, removed the fan hub and cut out the bracket, then smoothed it out, which now becomes a perfect duct adapter, and finally used standard 4" rigid aluminium ducting for dryers (I prefer the rigid ducting since you can conform it to make just about any shape.
I don't get it. Why would you need to do that with a rad? Just mount the rad directly on the side. If you can't then you bought the wrong case.
Summary: Yes
I just saved you 8.5 minutes of blather. You are welcome.
in addition: you save about 2-5C, so it's not that important.
@@satibel Hey man, every degree counts when you're on the cheap. This is more a proof of concept than a fleshed-out, optimized build so there's gains still to be had. He also admits his case doesn't have the best airflow from the front and the results might be better on other setups.
P.S. The smallest difference in temps was 3.8 degrees, so savings total is more like 4-5C
@@satibel try moving the duct to the gpu(s) it makes a major difference or give the gpu a baffle to redirect the heat coming from the gpu(s) from heat soaking everything else in the case the effects are much greater I am running dual overclocked 2070super graphics cards in sli with an overclocked I9-9900k cpu and my gpu's without baffle run my motherboard and CPU temp sensors approximately 20c hotter than with the baffle and dedicated fans
I installed a high static pressure fan to make my cpu a push-pull configuration accept the fan is hooked to an external adjustable voltage so I can make it blow more or less and it works wonders on keeping things cool. I also added another case fan to the side of my case hooked to the same circuit for cooling off my gpu.
I did exactly the same thing, have an 80mm pushing air into a duct that goes over the cpu cooler and another 120mm fan simply pushing air over my GPU. (My only difference is I have that 80mm plugged into the same power as the cpu fan so both can ramp up as needed.)
Internal Ducting was something that was done a lot and actually the first thing I tried to get better Thermals with my system. I have learned that having a big heatsink like that extremely close to the backside of the GPU can increase your Temps dramatically. (My system Strix Z270I; RAM @ 4266; BCLK@103.2; 7700K currently @5.150GHz with Noctua NH -D15; EVGA 1080Ti KingPin) At the Peak of case Modification, I had my system in a Phanteks Enthoo Evolv ITX case with the side panel completely removed, the Front panel Cut to add ~1"x12"" vents to either side, added a hole with Fan to the Top of the case, and the case on its side with air being drawn into the case from underneath through a hole I created behind the CPU (a total of 6x 140mm fans and 1x120mm fan adding airflow below a 140mm in the front) . Trying to use every bit of Thermodynamics to get as much fresh air to the system as possible and the Hot air out. While playing a 400+ modded Skyrim, I was running 85C on the CPU and unstable past 4.8GHz; 80C+ on the GPU. Then Since EVGA gives you that lovely utility with all of those temp sensors ... the backside of my GPU was running 96C. Way too hot and explained why I could not get the guaranteed overclock the KingPin offers. Then I found a "GPU Kickstand" deal to run the graphics card outside of the case. By doing this my CPU temps dropped 20C and even @ 5.150GHz still runs in the 60s under load with Peaks in the High 70s maybe an 80C from time to time when the room is warm. GPU Temps were still a little off for my liking but dropped into the high 60s, low 70s. Then I re-applied the TIM on the KingPin GPU with some Arctic Silver 5 (have a ton I need to use up) and My GPU with a slight overclock, now runs in the low 60s under load. Everything runs about 10C above ambient @ idle, now time to Upgrade and apply this knowledge to my next build. Going to Liquid Cooling from now on, I am done with air for OC.
Great experiment, and the results are not surprising. This is the reason why when buildings have properly installed ventilation ducts, the building can be properly and nicely temperature controlled 👍
Hi! I thank you for giving me the inspiration for a fix I probably need to perform on my setup.
See, I have a Coolermaster Silencio S352 that is housing my AM4 system that consists of a Ryzen 3600 cooled by an Coolermaster Hyper 212 EVO on a B550 board, with a toasty open air cooled 3080TI. The case is cooled with 3 120mm Noctua case fans with 2 of them for intake.
For normal operations, this is fine. However, when I was messing around with protein folding with, the CPU struggles keeping itself cooled when fed by the hot air expelled by the 3080TI. When folding is limited to running on the CPU and not the GPU, the CPU runs cool enough that I would reckon the Hyper 212 would be capable of cooling a planned Ryzen 5800X3D upgrade.
I was contemplating a cardboard shroud to physically separate the GPU and CPU like what prebuilts like Dell and Lenovo does for their SFF machines, but it does appear that your venting tube method is more elegant.
I'll see what I can do to mirror this on my setup. Thank you again for the inspiration, and have a good day! :)
G'day Major,
just watching some old vids today & came across this one, That 🦆Ted setup looks pretty Cool 😁
I've got a gaming PC in a media PC case (Not sure of brand, it was a gift). The CPU cooling fan sits right under the top cover and pulls air directly from the room and disperses it into the case. I can *always* tell when it's time to dust because my CPU will start running hot. For a machine that was built to run WoW a few updates back it still runs surprisingly cool.
You are the hero no one asked for, but everyone needs! Great work
A really cool idea, great vid!
Keep experimenting with waky ideas bro and il watch them all
A friend of mine actually did something like this for exhaust with a hot FX-8350 build he had. He attached a plastic duct connector from an auto parts store to his 120mm exhaust mount, attached it, attached a dryer duct, then attached a fan to the end of it. The case still had a 120mm fan on the rear, obviously mounted on the inside, so the duct had a fan on each side. It seriously helped him redirect the heat from his rig to an area where it was not a bother, instead of under his desk giving him sweaty feet and swamp ass lol.
yes in the room where i have all this it defiantly heats up over time, might need to do something like this
@@MajorHardware looking forward to it if you do!
Is it safe to have my computer exhaust fan pointed directly at the monitor???
Because I want to get more spacious in 150cm desk space by aligning computer straight with my monitor panel...
Like your PC case setup, but door TG panel more straight with monitor panel ( example -- )
I've done this using an extra duct running from the back of the case up to a window mounted air conditioner during the summer. I sealed up the sides of the radiator as well to avoid condensation build up inside the case and ducted the air out the front of the case. Worked better than I ever dreamed. You'll get better clearance if you can finagle your CPU cooler to face vertically in the case rather than horizontally, though not all coolers can do that.
My old opteron was setup with the cpu fan inverted and ducted out the top of the case. made a massive difference.
I remember the old Dell T series server computers had plastic ducting all inside. It was a beautiful thing!
Very cool work 👍🏼
my old single and dual socket 939/940 rigs were setup like this! when heatsinks were tiny and all copper. this was the idea behind the BTX form factor.
5:50 when the music kicked in, holy shit this guy is bringing it back
Some old Dell BTX cases did this. I had an XPS that did that, and load temps on my Core 2 Quad Q6600 were consistently under 50 C
Awesome vid. I suspect the deltas will be even higher with a non-blower card. The blower card is great for CPU cooling because it ejects its own heat. I suspect your 1080 will heat up that case a lot.
It would be intetesting to see the GPU temps as well. I wonder if the ducting hurts GPU airflow.
New meaning to "ducted fan"... I like it.
Thats really good idea I like it!
Air ducts were actually popular back in the early 2000. PC cases usually have side panel with ventilation (and sometimes air duct) right on top of your cpu cooler position
I still have cases that had that built-in, including a BTX case (Yes, I said BTX). My old iSTAR S-1000 Tower Case (Three gens old) actually had a side mount that allowed you to add a fan, and "aim" the duct directly over the CPU cooling fan of the horizontal coolers that were popular in the day such that mounted horizontal fans, not unlike the Wrath (the Intel stock, AMD stock, and Zalman bowl style were all common at the time). In fact, I worked for a system integrator at that time; and we built systems that would overheat in the case unless that case ducting was in and used. I believed that at one time it was even a required spec in the Intel 775 era.
But this was part of the reason why some early Watercooling enthusiasts swore by external radiators. I've seen some that just screwed the side of the radiator onto the top of the case and did a push-pull fan configuration through the radiator venting out the sides, so all the air for the cooling was outside air. Some cases like the Evercool even built this into the case. And many cases (all the ones with the round rubber grommets to the outside were designed to pass radiator hoses to the outside.
(edited for spelling)
I have done this back in early 2000s, on a custom build cheap AMD K6-2 350 pc, cut a big hole in front side of the desktop case (not mini tower), made air duct directly from that hole to the cpu cooler, built from cardboards and duct tape, replaced the standard cheap cpu fan with big case fan. The same design I found again in a mini pc in 2010s.
I found this video (and channel) completely randomly but thought it was an interesting concept. That being said, I'm currently learning solid works in class, so that made me giddy to see.
i wish i had a class when i started using it, im a mechanical engineer IRL and i had to learn it from just using it, which as you know using solidworks isnt the easiest thing.
@@MajorHardware Working toward my Mechanical Engineering Degree! And yes, Solidworks is quite finicky.
Years ago I made a cool-air duct out of a hacked up fan chassis and a 2-liter soda bottle. IIRC cpu temps dropped 10c under load. No intake fan, just a tube from cpu fan to outside the case.
I remember making a wind tunnel for a case fan -> cpu fan out of cardboard when i was a kid haha.
Looks like a Dr. Who "Cyberman" Build. Love it! :)
I always told that, if the whole CPU has a separate cooling like a tunnel from the entrance to the exit will improve performance, thanks for the video, this proved I was right and I had seen it many times on old PC's and even my old bought case had a plastic tunnel for the CPU to the side...
Just wished you had 2 parts of the video with the 2nd having that pipe from the front to the rear of the case the whole section and all CPU airflow completely separated to see the difference but also leave some other fans pushing air trough the interior of the case which will also reduce the CPU cooler by hitting the copper pipes and the bottom plates and all the components all over the place and all the other fans pushing the air out...
Though that case doesn't seem good to make a full pipe from front to the rear since it only has one back rear, my current case is very old and I have 2x 120mm fans on the front (had to mod the 2nd since there was no fitting for it), 1x 90mm above (however there's room to put way more, but would be kinda pointless) and I have 1x 120mm + 1x 90mm on the rear, so 5 case fans counting a total of 12 fans in my entire PC (5 case fans + 2 on the CPU + 1 on the PSU which also push hot air from the cpu out, 3 on the GPU and 1 on the motherboard), this is a hell lot of fans all over the place LOL.
@Major Hardware
*I am so happy that me and some other people were nagging on you to do this type of content. This channel is awsome, i think you can go far with this. Just give it some time:)*
Glad as well its a lot of fun although
@@MajorHardware Ah great looking forward to the next video!
I think a different type of fan would help, the designs from 10 years ago had fans that looked like a boat prop so they had amazing static pressure.
