I'm currently using an iMac 20'' early 2008 edition and I'm pretty sure I jacked something up. My last just HDD failed so I installed a new one last night. It was my first time every opening up the machine and installing anything, so it was a bit scary. Overall, it wasn't too bad but I did make one mistake. When unplugging the temperature sensor, I pulled on the wire instead of the plastic thing and the metal wires came out. I tried to stuff the wires back in and they seemed to fit back in fine. Anyways, once I started the machine, the fan was blasting at full speed.
That was yesterday. Today, I went back in assuming that I connected it wrong, but I couldn't find anything wrong with it. I unplugged the wires again and tried putting them in a little more firm. Still blasting away.
Then I tried doing a SMC reset, but that didn't work. I've downloaded two fan control programs, but can't get either of them to lower the fan speed. I tried HDD Fan Control Monitor Demo and iMac Fan Control.
Any suggestions on what I can do? I can't help but feel I'm going to blow the fan motor out if I leave it like this too long.
