Fan stuck at idle
I have upgraded my iMac (iMac Intel 27" EMC 2546) with an SSD and unlike most people my fan is actually stuck at idle, no matter the work load. Thus it's overheating.
I can watch the temperature rise on the cpu and yet the fan stays at 1200 RPM.
Initially I thought it might be because I had not installed the optional HD temp sensor, so I bought and installed one. Still no luck. I tried a couple fan controlling apps, and Mac Fan Control was able to change the fan speed, but I can't understand why it's not working on it's own...
Anyone experience anything similar or have any ideas on what I should do?
Is this a good question?
