Explain to me why a 2011 imac overheats GPU

Basically been going on for the past 3 to 4 months
GPU diode hits >84 degrees and imac crashes on labor intensive tasks.

The problem is now solved by using a fan control utility and ramping up fans. But seriously why is this necessary.
 
Also imac has been opened up and parts have been exchanged by apple servicing 3 times.

They claim nothing wrong but I still get it to crash.
 
mid 2011 imac 27inch indeed.

Took the imac in and they said that it needs to "fail" their video card test. If not, then go home. Mine didn't.

The problem is that they run hot as Hell, that's why they fail.

I'd call Apple Support directly rather than going through a third-party service centre as they have less power to get it sorted. Failing that, email Tim Cook.
 
No I am referring to apple store in large metropolitan area in Washington state.

I spoke to "apple geni" and techs there. 3 times, different people.

Do you have Tim Cook's email?

That's an absolute joke then, if they're official they definitely know about the issues and they're just being stubborn.

You can email him at tcook@apple.com. Naturally be courteous and polite as a firm hand won't get you anywhere, but you will have to explain the situation that it's a documented issue and you're losing faith in Apple's support as they're not accepting there's a problem - despite you actively experiencing an issue and the temperatures are getting far too high.

I wish you the best of luck.
 
Thank you. I think I will try a different apple store first.

I am aware of the problem you stated above and even printed out the notice and gave it to them.

thanks again
