Why have my fans stopped working
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

Lets see if we can isolate out whats happening here with some deeper diagnostics. Install this app TG Pro it will allow you to see all of the thermal sensors and the fans RPM's. Paste a snapshot of the main window here for us to see Ajout d'images à une question existante.
You'll likely need to grow the size of the window to get all of the sensors & fans to show up by stretching the bottom.

Thanks for answer but have done all this. I know its a physical issue and not related to software/smc etc. What I need is the location of the fuses or circuitry related to the ODD fan and CPU fan Thanks
