Any tips on how to fix this? Usually, the CPU fan is stuck at 4500RPMs constantly, CPUs 28°? it runs the fan at 5000RPMs. But whenever the CPU is cooking, such as 92°, it won't run at all, but the other two fans will be at full blast. Any tips on how to fix this? I took the computer to the apple store 3 times for this issue but every time they "could not recreate the issue". The last time the replaced the fans in the computer, but that didn't fix anything. Anything that would point me in the direction of fixing this? It's just melting itself. Alum. iMac. Thanks!
