I don’t know why but for some reason there is a fan in my pc case that is not slowing down after exiting a game. This is a brand new build And i’m not sure what the cause is
Monitor your temps, maybe they are never cooling down after gaming.
Maybe you need to reevaluate your cooling methods.
Which fan? Cpu, gpu, case? What software do you have for controlling that fan?
The stock case fans are 3 pin so it should be running full speed unless you can change the voltage in BIOS.
