This new computer is making unusual sounds.
Hello good people, I've finally finished my build and I ran into a small problem.So this problem popped up even on the first day of boot and still keeps playing with my nerves. I'll try my best to describe it: whenever the system has even a smallest load (opening a browser) PC starts making weird whirling sounds, but it's not constant, just comes and goes. Tried putting my ear to each component but can't make out where the sound is coming from. Tried stopping each fan but seems to me that it's not a fan speed related. Any help would be appreciated. video.mp4
Head over to 7s, it begins there—it's quite noticeable. I don’t believe it’s coil whine; I’ve experienced it before and it was much more bothersome, making it easy to pinpoint the cause. That’s what I’m considering too. I was thinking about tweaking the pump in BIOS to see if that’s the problem, but I’d rather not make any changes.
I hear it now. That to me definitely sound like AIO pump noise. There is absolutely no danger in playing with the pump speed in the BIOS You can put it to 100% and see if thats the sound and put back to where it was before. An AIO pump is designed to run at 100% pump speed anyways. Just play around to see if that is the sound or not, no dangers at all! Unless you do a 0% pump speed of course.
Test it out—swapping the pump seed has no drawbacks. Some enthusiasts prefer around 70% pump speed to enhance performance or tone.
Just like I set the maximum speed on all my fans silently, some users adjust their AIO pumps to a steady speed. From what I've learned over the years, keeping the pump at a consistent 70% or 65% is preferable rather than changing it constantly. This reduces wear on the pump, even though it might be higher than fluctuating between 35-60%. I've used a few AIOs in different builds and always ran them around 65-75% constant speed. For instance, I run my AK620 at a steady 29% fan speed.
I handle heat quickly and efficiently. The 12600KF is easy to cool, so my pump runs almost silently... and my case/AIO fans also stay quiet (they spin at 400 RPM). It stays nearly completely quiet during idle and even quieter when the CPU is busy.
Sure, if your CPU stays below 90°C, the pump will always run at full speed. However, with a 9800x3D design it behaves differently—it heats up more consistently, so a steady pump speed can help maintain performance since AM5 chips often reach around 90°C even without strong cooling.
...And the curve would still account for that, drop the response time to 2 seconds and you have what would function like a BIOS configuration just with a little bit of smoothing/tolerance for small spikes here. And let's not forget, you can adjust the temp target, there's no reason for it to be TRYING to hit 90C. Friend of mine has a standard 9700x with a DRP4 that was hitting 90C and was funnily obnoxious, he dropped the temp target to 80 and now noise is significantly reduced, temps are more reasonable, and he has no functional loss in real-world performance.
