Loud Fan while playing games

[Matthew Winters]

I have a loud fan only while playing games.

I'm not sure where it's coming from.

I have a GTX 970
AMD FX 4350 CPU
Aerocool 600W PSU

It's really annyoing while playing. How could I fure out what fan it is.

There is also a really big fan on the side of my case. Thanks

Run fan monitoring software while gaming, then look at the graphs after you close the game.

My guess is it's your GPU fan. For your system fans, only 4-pin fans can change their speed like this (and the GPU fan can also do this). By 4-pin I don't mean Molex, but I mean like the 3-pin motherboard fan header with an extra pin. (The pins are 2 for power [+12V, Ground], 1 for RPM monitoring, and 1 for temperature - to adjust the fan speed dynamically.) If you see any fans with only 3 pins, they cannot change their speed (though you can have a fan controller so *you* can change their speed).

Pure AMD gaming PCs do sound like jet engines when playing games

Thanks what SW should I use

To check fan speeds, CPU & GPU clocks speeds , temperatures, and utilizations I use HWmonitor from CPUID while playing game or benchmark in windowed mode.
