So I have been getting a lot of temperature spikes on my Macbook Pro, at first I thought it might just be the weather, but now that's it cooled off its actually gotten worse. Yesterday I booted up the computer and it was already hitting 100 Degrees Celsius. It was about 10 Degrees Celsius in the room. I've opened it up, cleared out all the dust and no luck. I've done an SMC reset, nothing. After that, I followed it by using SMC Fan Control to turn up the fan RPMs and still nothing. Any suggestions? I am thinking its last legs this is about a 4 year old computer.
