I installed a new ssd because my hdd crashed. The fan worked before i installed it but now its getting really hot and my fan wont turn on. Did i install it wrong? I bought the upgrade from here and i followed all the step. Help
i figured it out. I installed a 3rd party fan control. I had to manually set the temperatures so the three fans could spin up. It was weird because it was set to auto and it would not do a thing.
The thermal sensor should be responsible for this issue, you need to find a way to reduce the RPM of the internal fan down to the usual range. You may solve the problem with the help of reliable third-part software.
Did you install the in-line thermal sensor this system requires? OWC In-line Digital Thermal Sensor for iMac 2011 Hard Drive Upgrade. Its part of the SSD upgrade kit iMac Intel 21.5" and 27" (Mid 2011) SSD Upgrade Kit
