the cpu fan of my imac started to act in a funny way.
so since I am still covered by the warranty I decided to ring Apple and see.
now they told me to bring it to the mac-doctor.
anyone had experience with Tyrell? or eventually can recommend someone?
Mine used to to make allot of noise by spinning too fast but has stopped doing this now. Theres a tool at the below location where you can change the speed of the fan. Not sure if that’s the actual problem your having with your fan though….
