PC crashes when gaming when using a custom fan profile vs standard.
Hi everyone,
A week ago I upgraded 3 parts of my PC: CPU, MOBO and PSU. The rest of my parts GPU, RAM and storage are all carryovers from the previous build. Since upgrading I have run into intermittent black screens/hard freezes/bsod’s/reboots when playing games. Some of which would not even create a dump log, I have done by own initial troubleshooting. Making sure everything is up to date, BIOS, drivers etc with no luck. Replugging RAM, GPU, reseating cables still didn't have any effect. The one thing I noticed how I can pretty much guarantee to get it to crash is if I have the fan speed low in the BIOS it’ll crash when playing a game. I know what you are thinking and I did as well. It must be a temp issue as I moved to a SFF case. Many components are close together now so it would be reasonable that something was overheating. Sadly that isn't the case. I have used MSI afterburner and HW Temp and neither the CPU reaches higher than 83c and the GPU 70c. Testing in Forza Horizon 5 if I have the CPU and case fans at the “standard” mode (I have forgotten what it's called in the bios) my PC will not crash at least within 30mins - 1hr. Where as if I put my own fan curve dropping the speeds but still keeping the temps in check it'll crash within 10-15mins. This suggests to me something is overheating but im not seeing it in any monitoring software. I have done a fresh install of windows to the same problem. I do have a spare PSU which I will be trying at some point soon just to rule out the new PSU but other than that i'm bery much stuck as to what I can do next.
Honestly most likely the fan profile thing is just a coincidence that it'll crash when lowering it but still something I find abit strange.
The only settings I have changed other than the fan profiles are my CPU which I put in ECO mode and GPU I have decreased its power limit to 85%. The PC has crashed with both of these being stock so I'm pretty sure these are the culprits. Same with the ram XMP profile enabled/disabled makes no difference.
Thank you so much for reading my post. Any help would be massively appreciated.
