logic board getting very hot. idling at 90'c.
I was given a mac book pro 1278 early 2011 with an i5 processor.
Unfortunately it runs very hot ( around 90'c) whilst idling. I've checked and the fan is free of dust and spinning without a problem. I've also isolated the heat source to be eminating from the logic board as every other component is perfectly cool.
I took it to the mac store and they said it may be the hard drive as it was about to fail.
Yet this makes no sense? Firstly I replaced the hard drive with a brand new one as the 320 was too small and I can't see how a faulty hard drive can make the logic board overheat?
I will attempt to replace the heat paste. But will that make much of a difference?
Is this a good question?
