running a fan at 100% fans speed is a sign of mental illness. disagreement  with this is also a sign of mental illness. it means you are in a state of denial about reality.

set fans at 80 to 85%
see what  your temps are.

if under 70c you are fine.

when fans are in the 90 to 100 % range there is no real benefits for long term use.

and if a fan set at 85%  does not cool off your gear you are doing something wrong.

either over clock is too high or room is to hot. or voltage is too high.
