I've been noticing that one of my fans (I assume CPU fan - SpeedFan won't list my GPU fan and the noise increases correspond to higher CPU fan readings) has been getting really loud while playing games, and even a bit louder than usual during normal use (staggering around 2500-3000 RPM).

This has been happening since I swapped out my old Asus H110M-E/M.2 for an ASRock H370M Pro4, and swapped my old i5-7500 for an i5-8600. I've also added a new HDD and 2 sticks of RAM but I don't think that's relevant. My GPU is a GTX 1060 3GB, which I haven't changed.

SpeedFan has been reading my CPU reaching about 80°C and my GPU reaching about 75°C while playing Portal 2, a game that isn't really resource-intensive. I'm not sure what the temperatures were before changing parts, but I assume they weren't as high since the fans weren't so loud.

The CPU fan I'm using is just the stock one that comes with Intel CPUs - I know it's not that good, but I was using the same type of fan for my last CPU and I never heard it get this loud. I also have front and rear fans in my case, so circulation shouldn't be an issue (I didn't move or change them anyhow).

If anyone has any idea of what might be happening, I'd really appreciate any input.


  • I typically use aida64 to run a burn in test and monitor CPU temps. You can run a trial. Without a good idea of what your system is actually running at from a completely cool, idle state to maximum load for 15 or 20 minutes you can’t really tell if it is normal or not. The most likely explanation is that your heat sink has not been installed properly or you need to adjust the fan profile in your BIOS settings. – Appleoddity Jan 2 at 6:01
