Using HWMonitor, PSU Heatsink 1 is showing 90+ celsius
I have a mid-2010 Core-i3 iMac, and it is suffering the identical issue.
Using HWMonitor, PSU Heatsink 1 is showing 90+ celsius.
SMC Fan Control does alleviate the problem, and most temps drop 5 to 10 degrees (iMac is audibly louder tho). Idle temps for the Core i3 are ~50 degrees, so not very cool, but so much better than before.
I am almost convinced that this is built-in obsolescence, as lots of people report the same issue.
I have had the entire graphics sub-assembly replaced under warranty, as the fans used to remain at 100% (AHT found the error and code). Now, my hard drive is often hitting 50 degrees, and signalling another HWMonitor alarm.
I'll stick with SMCFanControl until I can find a replacement unit.
PS. Computer had never cut out due to overheating (possibly once, but could have been power failure as well).
Is dit een goede vraag?
Craig, how about posting your own question. I bet we can get to the root cause of your fan/heat issues with some good diagnostic effort. ;-}

As to planed obsolescences: We have some older gear which are still running strong! Most of the issue is no different than a car you need to maintain it! Checking the fluid levels & tire pressure. I this case its cleaning the dust buildup checking the fans and making sure the thermal paste on the CPU & GPU's is refreshed.
