I just finished building my first computer and noticed a buzzing noise under different circumstances. It seems to mostly come from the PSU when the video card is under load. I also detected some degree of buzzing from the motherboard and the PWM fan hub. My question is whether this is a cause for concern and if there is a way to mitigate the noise. I provide more details below.
My build's specs are:
PSU noise
Most noticeable when running Furmark's stress test at 3440x1440 (60 fps) and sometimes when playing Metro 2033. I haven't tried other games. The noise sounds like electric interference. Here are two samples, air exhausted from the PSU masks the noise in the recordings, but you can still hear it if you increase the volume. I can also hear a similar noise from the fan hub, but less loud. For Metro 2033, the noise is on or subdues depending on what is displayed on the screen. There is one room at the beginning of the game, for example, where the buzz is loud, and if you aim to the ceiling, the noise subdues, but the frame rate stays the same (91 FPS with G-Sync, V-Sync, and EVGA's XOC Precision FPS limiter enabled).
With respect to the PSU, it is important to mention that I did a separate test in which I ran Prime95 (Small FFTs and SSE enabled) and Furmark at the same time, and the computer shut down after around 10 minutes. When this happened the CPU temperature was 80 C and the GPU was 67 C, so maybe the PSU overheated and shut itself (?).
Motherboard noise
Not as noticeable as the PSU noise. It happens in IDLE sometimes when moving the cursor across the screen or in Youtube videos. It is a slight buzzing noise reminiscent of a dot matrix printer. I could not hear it when Prime95, Furmark, or Metro ran. This noise was a little more notorious before I disabled "Enhanced Halt Mode (C1E)" in the motherboard's bios. I also tried disabling Intel's SpeedStep, but it didn't make a difference and was preventing the CPU to turbo boost.
Once the side panels of the case are placed, and the computer's speakers are on, the noise is not very perceptible. But I still would like to know if there is something I could do to remove it, or if I am facing a more serious problem. I would prefer not to replace components since it was very difficult for me to assemble the machine in such a tight space.
I'd appreciate any help provided.
