Hello!
So, I've been using this PC for about 2 weeks now and whenever i'm playing games, it seems as if my computer is louder than before when under load. I'm not sure if it's coming from the CPU cooler or the GPU's fans, but there seems to be a sort of "vibrating noise" whenever my fans are spinning, it's not super loud but it's constant. The noise goes away immediately after exiting a game. (It doesn't sound like coil whine)
I'm pretty sure that this noise came today, since I haven't heard it during the past two weeks. However, my ambient room temp is around 25C and I have been using this computer heavily for gaming. There does seem to be some dust in the PC, even though my intakes are filtered, I need to clean that out.
Here are my temps/fan speeds while playing Witcher 3 when the noise was present: (ambient room temp 25C)
CPU Max temps: 61 C, 61 C, 62 C, 59 C (overclocked at 4.4Ghz)
CPU cooler fan speed: 1231 rpm
System fan 1: 734 rpm
System fan 2: 691 rpm
GPU temp: 76 C
GPU fan speed: 2568 rpm @ 70%
IMO everything seems normal? My specs are in the sig, but here are the important ones; GALAX GTX 980 SOC (I haven't overclocked), ThermalRight True Spirit 120M BW rev. A, 2x Fractal Design Dynamic GP14 140mm fans.
So, any ideas what it could be? Dust, GPU/CPU/Case fan bearings, GPU vibrating against motherboard heatsink? I'll take a closer look at the PC tomorrow.
