I’ve always kept my GPU fan speeds around 20% on idle. In my mind, I’ve always felt that keeping your GPU and other internal components temps down would prolong the longevity of your build but Im reminded that keeping your GPU on zero RPM mode at idle is better for your GPU in the long run because it prevents wear and dust on your fans. So what’s worse for your GPU, wear and tear on the fans as well as dust OR moderate temps (30-40 degree F) on idle? I have an EVGA RTX 2080 XC Ultra which has a pretty thick heat sink but I haven’t replaced the thermal paste in about 3 years.
