hello!

So my PC fans have been running loud constantly. no idea why, they've been this way for months and no Im getting so tired of hearing them all the time. can someone please help me make them shut up! Here are the Fans Speed, Task Manager images that i uploaded to help diagnose. as far as my BIOS i tried with the QFAN settings set to silent and they were still just as loud.

Here are my specs

Operating System: Microsoft Windows 10 Professional (x64) Build 19044.1645 (21H2)

ASUS TUF GAMING X570-PLUS (WI-FI)
AMD Ryzen 5 5600X
EVGA RTX 2060 XC GAMING (06G-P4-2063)
24 GB a-data ddr4 3000

thx in advance!!!

  • So I have 4 fans in installed
  • (exhaust) 2 at the top/1 at the rear - all 3 120mm
    • These 3 ARGB fans are connected with a cable to join them together
  • (intake) 1 140mm at the front

You've got an awful lot of exhaust and not very much intake. Typically you want slightly more intake than exhaust.

Prime95 loads the CPU with a constant heavy load. You use that to monitor CPU temps to determine if your [stock] CPU cooler fan is loud.
Furmark load the GPU with a constant heavy load. You use that to monitor GPU temps to determine if your GPU fans are loud.
The nice thing about these...

Way back when..when they were not so noisy......were they at that time generally spinning at lower RPMs than they usually are now?

Or are they noisier now at the same RPM?

The human memory for sound is notoriously poor.

You played with QFAN settings......did that in fact lower RPMs per your speed monitoring application? Or not?

Do you have any reason to think the fans are wearing out....bearing noise, squeaking, etc. Or are you complaints just that the "whooshing" noise that all fans make is louder than it used to be?

How averse are you to replacing the fans?

Yeah, we don't have anywhere near enough information to help you. Do you even know what fan(s) are loud? Case fans, GPU fans, CPU fan(s).

  • What case do you have
    • How many case fans, what size, where are they installed, what rpm
    • Does the fan noise get noticeably quieter if you run the system with the side panel removed?
  • What CPU cooler do you have?
    • If you run Prime95 Small FFT stress test, what is your CPU temp and CPU fan rpm
  • What is your GPU temp and fans rpm when tested with something like FurMark for 10 minutes.

Ill answer the question in order.
  • I just started noticing the loudness overtime. i think that's normal, but they've been this loud and that RPM for months.
  • No, After QFAN and setting to silent they were still loud and RPM was still high
  • hmmm I'm not sure but how can i tell? i don't hearing any abnormal noises, just the fans sounding loud.

The fans are just as loud with side panel removed.

With the above in mind I just noticed something interested in HW info. the CPU temps are fluctuating up and down a lot.

Specifically the CPU Tctl . Not sure if that's normal. There's about a 10 degrees celsius differential when it's fluctuating.

Gonna investigate this a bit.

Update: Things have gotten a lot quieter, opened the side panel identified which fans were which CH3, CH2, etc. and realized some of the fan were set to run at 60% speed minimum 🙁

Check out the latest screenshot, running a lot quiter but the CPU fan is kinda wild!! im running the stock cooler for ryzen 5600x.

I'm more than willing to buy a new better cooler (feel free to recommend any) if that is what it will take to fix this. I did adjust the QFAN control for the cpu but didn't help much.

Also should have mentioned, my goal here is whisper quiet when not gaming. b/c I have a sensitive mic that picks up everything lol

The nice thing about these stress testing programs is that they provide a constant and heavy load, while also being windowed. That way, people with a single monitor can reliably watch temps/etc while the test is running compared to a game that you'd really want/need to log data or have an overlay. Games aren't a constant load, and rarely sustain ~100% utilization. Stress testing programs are designed to be a "worst case scenario".

Yeah, the stock AMD cooler is...fine, but certainly not great/quiet. What country are you shopping in and what's your budget?
My brother has a Noctua NH-U14S and while it's massive overkill for his 5600X, it barely breaks a sweat and is therefore VERY quiet. There are many other options obviously.

^ This one looks good for $30 ($15 off right now). 5 heatpipes, a solid base. The 2nd fan probably isn't giving much additional benefit, but it costs the same or less than the single fan model, so why not.

Your bios should have a fan setting section in the form of a graph.
individual fan speeds can be set to vary, depending on a factor such as cpu temperature.
It looks like they are now set to a constant speed.
I like that for the chassis fans, but the cpu fan should be responsive to cpu heat.

Thanks for the advice tennis!

Ill pick up a new cooler, and look into the intake fans.

No budget for a cpu cooler, just no water cooling. Because i dont wanna deal with water leaking like ever.

I was looking at the deepcool assassin 3. Wish it came in all black and 140mm though 🙁

No OC, just literally browsng chrome and then (loud fans) nothing running in the background.

I work in tech so I've done all the basic troubleshooting.

And like I mentioned above, I got it quiet now aside from the CPU fan. Ive concluded the CPU just runs hot, so a new cooler will fix it.

Also wanna replace my single fan 2060 but this isn't a prority right now.
