Have a late 2009 27” iMac. Both fans have stopped working. SMC reset hasn’t fixed it and a good replacement fan also hasn’t fixed it either. iMac starts and works OK but obviously it gets hot. Are there micro fuses somewhere that may have blown, and if so where are they and what do they look like. Thanks in advance
is the activity monitor showing fan is functioning ? is dust build up on the system ? if yes did you try blowing of the dust ? Have you try replacing the FAN?
