I have noticed that when you have Multiple fans on the same PWM channel. You get harmonic resonance( sort of a rhythmic hum) from all the fans. However if you put each fan on its own PWM channel ( use a fan controller or individual headers on your motherboard) you don't get as much resonance even if the fans are all running at the same speed.

I can't believe what a great and thorough test and analysis you did on this content. I think you answered any question anyone could possibly have about fan sizes, RPM, configuration, direction of flow (and various combinations). Most surprising to me was how detrimental having the top fans as rear exhaust, front intake, to cooling; I thought at worst it would be about the same as having no fan there, but that was completely wrong. This goes to show the importance of deliberate, scientific, testing before reaching conclusions. Thanks for this!

I'd like to address the off high pitched hum that comes from the P12 at 1000-1500 RPM. You can hear this in this video:kzfaq.info/get/bejne/qMhphddmrJe-nIU.html Once the PWM value is in the range of 41-65 the pulsating resonance hum is noticeable, especially when in the specific resonance. They work very well as case fans at constant RPM. I'd just note the extra fan tuning, to avoid the humming RPM range, if they're being used on a Ryzen CPU cooler (which constantly spikes unless using RyzenMaster.) The same thing occurs with the P14 except lower frequencies.

When thinking about multiple fan setups in a case, it's useful to think more in terms of pressure than airflow. An intake fan generates a high-pressure zone, while an exhaust fan generates a low-pressure zone. Air always moves from high-pressure areas to low-pressure areas.
@TheTechBuyersGuru3 жыл бұрын
That is a very good point. But air doesn't always move from high pressure to low pressure, it has to have a pathway to do so. So putting a high pressure fan in the wrong place means low airflow, and hence poor cooling efficiency.

After seeing that you got better GPU cooling with one front fan vs. two, I tried this out and got some different results. I got 2 degree lower GPU temps with 2 front and 1 rear fan than with 1 front and 1 rear fan, where you got two degree higher temps with the two front fans. All fan speeds were locked for this testing, I think the problem with your 2 front fan test here is that you've put the second fan in the top position, rather than the bottom one. In my testing, two fans in the middle and bottom positions improve cooling for both the GPU and CPU vs just one fan.

I was told that 140mm fans were "better" than my 120mm fans, but I wanted to see for myself which eventually led me here as not a lot of people do these kinds of tests for fans. Your testing so far seems the best since you only have 1 manipulated variable (the fans) while everything else including the ambient room temperature remains consistent. I honestly cannot thank you enough for what was likely several hours of work testing all of these configurations.

Hi friend, thanks for the precious time you spent, I have the same case and both Arctic P12 PWM and Noctua NF-A 12x25 PWM, it is clear that every computer, case and fan will make a difference, every case is unique, I have put 3 Arctic P12 in front (away from the filter) and 3 Noctua NF-A 12x25 1 rear and 2 top, the noise is almost absent at low speed but if I increase the Noctua are heard, previously I put Noctua in front (near to the filter) and Arctic rear and top, the noise is also absent in this case at low speed, but if I increase, the Noctua are heard! then I did another test with the Noctua (away from the filter) and I get an annoying resonance noise from the bearing, it is really difficult to find the right compromise between performance and noise but I want to say that the Noctua even if they are noisier, they blow more air than the Arctic and the temperatures drop by 2/3 degrees, the Arctic P12 are nice and very quiet but do not blow much air, certainly the biggest problems occur in summer and with these hot temperatures, if the room is not air-conditioned you have to increase the speed and bear the noise, this is the only solution with any computer, case, fan etc ... if the room is air conditioned then you can also run all the fans at 1000 rpm in idle and get a nice fresh computer!

Was great setup for cpu, vrm and oc'ing - basically the only thing that system was good for. I really love your fan content. I thought 4 140s would take it over the 6 120s because of the lower speed. Good stuff as always.

If you look closely at the dBA-normalized 3DMark graph for the extreme setups, you'll see that the 4x140s were excellent for CPU temps, but not quite as good for GPU temps. I suspect that if I had lowered the bottom fan below the level of the PSU shroud, the temps would have (counter-intuitively) been better for the GPU.

That is an interesting concept. Perhaps something for me (or someone else) to test in the future! My hunch is that airflow fans are never as effective as people might imagine, because there are very few applications in a case that have low resistance. Exhausts are actually fairly high resistance due to the grilles they must push through.

I have an arctic liquid freezer II 360 AIO as well so I'm excited to see how removing the air cooler from the flow path affects temperatures. Gonna set them up in a 3 front, 1 back plus AIO top exhaust configuration to see how it goes.

Arctic fans are solid budget fans, and the 5-pack is a wonderful value. As an alternative, I recommend MetallicGear Skiron fans, whenever you can find them for a good budget price. They're made by Phantek. These fans are a slightly better 9-blade design for airflow compared to Arctics, but more importantly, the Skirons are close to the cheapest case fans you can which include rubber mounts to reduce vibration noise. Decent quality rifle-bearings, slightly improved on the ball-bearings in Arctic fans. Arctics have a cooler motor, however, which increases their lifespan over the Skirons.
@DivergentDroid3 жыл бұрын
I leaned something about case design. I normally run around 36 C according to HWMonitor. I pulled the front of my pc off to discover a huge hole on top of the one fan that the case uses in the front. (hole was there to add a fan) I reasoned this cannot be good so I sealed up the hole and got 2 degrees cooler consistently now that the one fan isn't pulling hot air from inside the case. I thought o.k. I can do better than this. I had an old fan I pulled out of an old pc installed it even though it was a smaller fan, sealed up the edges again and now I'm getting a consistent 32 C at idle instead of 36 C. Moral of this story, always seal up any holes your front fan may use to pull warm air inside the case from and add more air intake if you can.

I've experience harmonic resonance issues with noctua that are not going to show up on a "decibel meter", but I would rather have high decibels than to hear that awful sound. I don't know how anyone can work next to a machine noises like that all day. The cons of having good hearing I guess. You also make a great point to control the RPMs of the fans to get the right amount of airflow where your specific case isn't making groaning noises.

I had the same result with my single 140mm intake fan: the lowest position is most beneficial to the GPU. My case doesn't have any grate above the PSU and as I was thinking about the turbulence occurring when the air hits the back of the PSU, I placed a makeshift curved ramp out of cardboard leading up from the bottom of the case to the level of the PSU. That shaved off another 1.5°C of the GPU temps. By the way, my rear fan is an intake (at 300 rpm) and I only have one exhaust fan in the top; CPU air flow is reversed. That was the optimal solution for a CPU tower cooler (at moderate rpm) and an open "blow through" GPU (Sapphire Pulse RX Vega56). Otherwise the CPU cooler was sucking in that hot air from the GPU.

At 600-700rpm they are super silent and have a very pleasant sound, while moving relatively large amounts of air, certainly enough to keep everything cool. Between 700-1100, they create some slightly annoying turbulent sound, which stops at 1200rpm... here they have a louder, but pleasant sound again. Therefore, I recommend them for either silent or maximum performance builds.

killer Vid. Linus Tech Tips made a similar one but didn't discuss the ins and outs of exhaust vs intake fans in the top, or the interplay between 120mm and 140mm fan types. I bought a case that unfortunately didn't allow for top mounting of a AIO pump bc of space limitations (it bumps against the mobo / ram) so this vid is a rescue of sorts.

I do heavily edit my videos to cut out the chatter (stuff that seems interesting as it comes out of my mouth but isn't once I listen to it!). Truth be told, I fully expected different results, even testing the setup that I thought was "right" at the end so I could keep it running in my system only to find that it was terrible (that was with the top fan flipped). I do hope that this video opens up a new dialog on PC cooling, because I don't think some of these issues have been fully examined thus far. Of course, I left about a million variables on the table for others to play with, so it's not like this conversation is over, it's only just begun!

@@TheTechBuyersGuru This message is a bit lengthy, I get carried away in writing/research sometimes and then realise what time it is and how long I've invested towards sharing a suggestion. From my perspective, your last video has opened up a whole new ballgame in regards to testing, the problem is, there's no way we could expect you to cover each new door. I went through the latest comments on this video, which you've done a stellar job at responding too. It seems some people would still like you to take their suggestions into account with testing, but with your level of detail, their requests are much larger than they realise. Perhaps in the next video, you could consider leaning in a different direction, allowing you to still follow-up on this content by keeping the users engaged and not putting an unrealistic workload on your shoulders. I had two thoughts in mind: Directly asking your fanbase to experiment using a set of specific parameters. You could document three-five different types of experiments you'd like to see numbers in, then assign two volunteers to each experiment(if available). I'd imagine that some of these tests would help the users construct questions or statements that may make it easier for you to strategically invest your time. Their results would not be conclusive in any way; it would just help lead you towards something in which you deem interesting or valuable. The second was sending out emails to individuals who handle airflow/circulation at a professional level, something like a structural engineer working in the airflow department. Briefly explain your position. You're trying to give individuals insight to maintain their hardware safely whilst also educating users enough to indirectly lower sales towards poorly engineered cases and fans. The last statement changes depending on who you're contacting; it's supposed to be a reason that relates to their values/morals/ethics. Ask if they have time for a couple of questions if so, show them a diagram of what you thought would work, and why; then followed up with what seemed to have worked. If they're hesitant in helping, you can mention that whichever professional adequately supports will be mentioned in that video with a thank you, as well as their business subtly brought up. E.g. I want to thank John for yada yada who's currently working as an Air Conditioner manufacturer for X company." There are also some interesting ways of measuring airflow from some brief Google search pages, perhaps if you were to use a tool to take a few measurements in your worst and best case-fan setups, you might be able to find similarities which turn out to be consistent with future tests.

Only really corner cases I would want to try/see is 3x120 front with only one 140 back and top, possibly while blocking the space for the front top mount, or the split dual 140 front (which is what I'm running currently) This was a beautifully done and largely complete video. Quite impressed. And I was absolutely looking for a video on exactly this (and even this case, luckily enough). You've convinced me not to add 3x120mm front fans.

Oh, yeah, this was all a theoretical test assuming you were coming from no fans. In terms of tossing two 140mm fans and buying three 120mm fans for a minimum of $30, it's probably not worth it. With that said, the default configuration of the case is 1x140 in front, top, and rear, so I would absolutely suggest swapping out that single front 140mm for triple 120mm fans, and then putting the second 140mm on top (despite minimal benefit, because you'd already have it and it's greater than zero!).

I am going to change mine to the 3 front 1 rear 1 top and see if it helps my temps.

Most people haven't watched my videos, so they don't know anything about what they are recommending! Are Arctic's good? See this video: kzfaq.info/get/bejne/hruUpreat9PZpYk.html If you decide to get them, here's the link to the 5-pack: amzn.to/3APDGQ5 By the way, your high idle temps are not a reason to buy any case fans at all. Idle temps are driven entirely by the fans on the coolers and the settings you are using. I recommending using a manual fan profile on your 2080 Super so that it's NEVER at zero RPM. While that's a popular fad, it's not actually very good for anything, including maintaining idle temps, because any modern GPU will slowly climb up in temps until it requires the fans to toggle on and off, which is more annoying than leaving them on. In terms of your 3900X, idle temps are always going to be that high due to background tasks and the density of the chip. It's the CPU I bench with.

This set up uses 5 fans that can be bought from the value pack, provide airflow on the vrms closest to the Scythe fuma and provide cooler air in a more direct way to the GPU !

This is indeed a really interesting idea, and I think adding that bottom fan is a great idea. You'd just have to make sure to flip the fans on the Fuma 2 to make that reverse airflow work, and I'm not sure they'd be quite as effective in a pull arrangement as they are in push.
@sakkidis3 жыл бұрын
@@TheTechBuyersGuru If the fans are reversed, they would be on a push configuration, pushing fresh air from the back and pulling it in the case , where it is immediately exhaust by the Top fan, am I right ?
@TheTechBuyersGuru3 жыл бұрын
Push and pull refers to the orientation of the fan on the heatsink (or radiator) fins. So if you have reversed the airflow in your case to go from back to front, then you need to flip the fans on the Fuma 2. This makes them "pull" fans, as they are pulling air through the fins, not pushing it. Fans are typically a bit less effective in this orientation.

Tho I wonder if not being able to use 3x140MM fans in the front didn't skew most of the 140mm results due to not enough air intake causing the exhaust fans to "pull" air from wherever and raising the temps. Would be interesting to see if a bottom mounted fan(right under the gpu) like old cases used to have wouldn't improve GPU thermals by a bit.
@TheTechBuyersGuru3 жыл бұрын
I think there's a big opportunity here for case manufacturers to change their designs to allow for bottom-mounted fans. The PSU shroud has improved the look of PCs, but not necessarily the performance. My biggest wish is that more manufacturers start rotating their PSU placement like the unusual Cooler Master SL600M - amzn.to/3n0f8fj It puts the PSU in the front and allows unobstructed bottom-to-top airflow. This is perfect for GPUs, although for CPUs it may require liquid cooling for optimal performance.

P12 seems better suited for radiators, heatsinks and cases where there is a lot of air restriction
