Hi, i have a mid 2011 imac 21.5 inch. A while ago i decided to do a variety of upgrades to this computer and i installed open core to use modern macos. Everything seemed to be fine until it wasn't. I started facing a high fan speed issue. Originally i thought it was the hdd because i had swapped it out but i found out after that fact that my soldered bypass for the sensor had been successful and it was actually the cpu that was causing issues.
Now my cpu fan runs at a reported 4400 rpm. For the record i upgraded my cpu from an i5-2400s to an i7-2600s. I dont know if this upgrade would cause this issue but I've exhausted most of the other known issues with these old imacs. If you know what cause be wrong with this imac.please let me know
