Will running the fans at maximum rpm all the time hurt the computer? I installed Macs Fan Control and I like to make both fans in my mac work at top RPM available all the time. The sound does not annoy me at all and I really like that the computer runs cooler.

Will this hurt the computer in any way?
Depends on what you mean exactly.

It will most likely mean that the fan itself will have a shorter lifetime before it fails. How much shorter is very hard to say - it might not mean much in practice.

The rest of the computer will definitely not be hurt by the fan running faster than usually.
