What PC fans do you use and prefer?

[Gymrat76]

Thanks, I started playing around with it. It's pretty good and I like how I can set my rear intake fans to match GPU temps instead of the default CPU temps (or a combination of both) as I want that to cool my RAMs and SSD more than the CPU.

Left the GPU controls alone as I think the factory setting is working well for me. From a quick test I think my temps are a little lower but will need to game a bit longer when I have time and monitor to see if there are truly improvements. Will also be good once my Scythe Kaze Flex slim fans arrive so I can play a bit more with it. With only 2 fan headers on this mobo (excluding CPU), will need to bunch a few fans to the same control, but that should work fine

Installed the Kaze Flex slims as bottom intakes and I've seen so far a GPU temp drop of around 2-3C at load.

Been trying to use the fancontrol software to set a curve for the bottom intakes to be as close as that of my GPU, but just realized I'm not able to set the case fans to 0 RPM (like for my GPU in fan stop mode...300RPM or so seems to be the minimum). Would have been nice to be able to do that so that the fans only kick in around 60C when it's under load like for the GPU.

Adjusted my CPU fan curve 30% until around 55C before it ramps up to 95% at 80C.. similar with top exhaust except it starts ramping up at 60C.. No point I guess to keep fans spinning faster than they're needed if the temps are at a safe level?

Case fans shouldn't be set to 0 rpm. The case's overall airflow (case intake and exhaust) is what allows your GPU to stay at 0 rpm while maintaining a stable idle temp. I typically set mine at about 40% when idle.

Personal preference. I usually tune my fan curves for noise; if I can set the fans at 40% and it's equally quiet as 30%, I'd leave it at 40%. How you set you curves depends on what your sustained load temps are, and your tolerance for noise. On load conditions, I find it better to ramp the speed up to your max ceiling for GPU fans (easier to keep the card cool from the start, than to let it heat up and try to remove the heat after). For CPU fans I set a stepped curve where the CPU fan ramps up to 85% past 80C, and 60% for 60 - 70C; the case fans are tied to a separate mixed curve (CPU/GPU) with a max ceiling of 75%.

Thanks, the one I want set at zero RPM would be the bottom intakes (where I have the Scythe) as before I added them, there was no fan and the GPU temps were fine at 30+ to 40 on idle anyway. So no further benefit to the fans running when the GPU is idle, only to provide more cooling when it's at load. I would leave CPU and top exhaust at where they are at about 30% or so until it hits like 50C, and have the setting where the RPM doesn't drop immediately upon going below 50C.

Will try this out and see how it works but the FanControl software is definitely good. Will drop him a small donation

I am currently using those racks (thin metal plates with 4 aluminum legs) attached with 120mm fans (made in china), usb powered. They served me well but the fans are wearing out and not so efficient in cooling already (quality not so good) so thought of swapping them out with Noctua A12x25 5V USB powered ones and use back the metal racks/mountings. US$29.90 a piece for the 1900 rpm A12x25 model, I got slots for 6 fans but think will replace 3 + 1 (spare) of them for Noctua (now no stock), hand itchy always see pple buy Nortua fans for their DIY PC so wanna try them out to see whats good about them (silent?).

I don't know if it is worth buying a Noctua for it. You can buy an Arctic P12 for around 12 bucks or lower, and a 5V 4 pin fan connector to USB quite cheaply. At 5V, most good fans are whisper quiet because they are running around 1K RPM, or around 50% of their rated max RPM.

Actually I originally had the impression that the cheap 120mm USB fans are lousy, but after using one that runs 24/7 for more than 2 years (should have exceeded 21000 hours of usage now) as a vent fan for the toilet, I have to say, I am impressed when you consider that it is exposed to both dust and a lot of moist. And I think this is a sleeve bearing fan that is usually considered lower end.

I don't see the point to set the case fan to 0 RPM. The reason for the case fan is to ensure airflow within the case, whether the system is under load or not. If the case fan stops or too slow, the internal will just heat up faster, and will trigger all the fans to speed up. And because it reacts to a set temp, you will normally end up with higher temps in the system even at idle.

Agree, as I clarified in the post above, it's only for the newly-added bottom intake fans, which don't significantly contribute to idle temps, only during load. Top exhaust and CPU I would keep running at a min level during idle, not possible otherwise in our climate

But you need to consider that the intake for the NR200 comes almost solely from the bottom fans, unless you have mounted side fans. Having exhaust fans only will still result in cool air getting sucked in, but I feel it is generally not as effective as having fans blowing cool air in at the same time.

Don't think it's a problem as I'm not using the TP side panel, so the entire case is pretty well ventilated. Before adding the 2 bottom intake fans, my idle temps were fine (CPU 30-40, GPU 30-40). Anyway, the Scythe are not able to go to 0 RPM, so I'm keeping them at the minimum 300RPM to avoid faster dust buildup lol

the 300 got tolerance btw

also, if u put 1 fan -2 to 3 c means your case is starving for air

this one was discussed few pages back, so i suggest u just leave it on lol

dust is bo bian one

It's 2 new fans as bottom intake and yes, they're on at 300RPM (+/-). ramping up from 50C GPU temp. And it's only at load temp (I guess it provides a bit better airflow to the card and other components at load compared to no fans in the original config). I definitely see improvements in DDR5 temps by 4-5C as well as I think the case fans helps to ventilate and remove some of the trapped hot air above the GPU back plate.

New fan from BeQuiet. M&M does quite a good review on the Silent Wings 4 Pro

I waited 3 weeks for mine plus the c14S the last time

I had BeQuiet SW3 before, they are indeed really quiet, more so than my A12x25. But by just putting my hands in front of the airflow, I can feel the static pressure of the BeQuiet loses out significantly. Their blade design is optimised for low noise, but lacking in pressure. I won’t recommend them for radiators.

Rads just slam the T30 on it.

Indeed, the T30 slams air through anything.

I feel the key issue with BeQuiet fans are that they tend to have a low RPM, thus, it’s quiet but at the expense of airflow. I believe they can overcome the low airflow if they allow it to run at higher RPM, but I think it can get noisy.

Now im just waiting for the 140mm versions.

The air flow is just insane
