My 24-inch early 2009 iMac (which has had the HDD replaced twice by me) has just started running with the fan at full blast all the time. I already have this on my other iMac and it works great to keep the fan regulated well.
I just downloaded the latest version from this website and installed it on this iMac and restarted the computer. But I get the message "No fans detected on this computer". It detects one disk drive temperature sensor.
What's going on?? Will it not work on this iMac??
Thanks!
