CPU usage at 100% causing overheating
My father just gave up on this iMac since it have this overheating/full processing for long time.
He tried to some specialized apple partner here in Brazil, cleaned up fans, etc, updated to Snow Leopard, upgraded RAM to 8Gb... but no solution...
So I got the iMac with 8Gb RAM, 500GB HD with 50% usage and I'm trying to identify the issue.
So, I've got some scenarios...
1st scenario:
- dashboard with some widgets (istat pro, weather, calc);
- running safari, chrome;
Result: after about half an hour, it keeps growing CPU usage to about 70% and then suddenly goes up to 100%.
2nd scenario:
- dashboard with no widgets;
- running chrome;
Result: running fine, half an hour later, started to configure mail, notification center and opened App Store, CPU usage runs up to 100%.
3rd scenario:
- running chrome;
- downloading Mavericks;
Result: running normal. Low CPU usage (around 10%, 15%) with some peaks around 60%.
4th scenario:
- only downloading Mavericks;
Result: running normal. CPU usage at 5% with some peaks around 20%.
Tried some tips that I found at Apple Support forums (SMC and PRAM Reset).
Any tips?
