3 Overheating: 90-100C; Random shutdowns
My last battery was 3rd-party and cheap, and I assumed that was the culprit, but after replacing it with another better 3rd-party battery, my voltages aren't wildly dropping anymore, but still I'm getting random shutdowns which now I think could be due to overheating.
- I've replaced the thermal paste twice and cleaned the dust. Last time I replaced it, the temps seem to be higher than before. Right now my CPU is <10% and still I'm idling around 70-80C.
- See this mini-heatsink here that covers 2 chips? It wasn't actually connected with thermal paste - it was a small peice of white foam. That foam broke upon removing the heatsink, so I don't have it, and now the heatsink perhaps doesn't make contact with those 2 chips. I once tried to use a big glob of paste to connect it but it didn't make much difference in overall temperature.
- I read somewhere here that someone removed it and resulted in their temp problems being fixed -- attempted but no difference.

What's going on, any ideas?

@breathlungs the mini-heatsink is your chipset heatsink. The "white foam" was most likely a thermal pad. I would try to replace it. Thermal paste on this is not the way to go.

@oldturkey03 Thermal pad, alright. Will ship around or scavenge something.
Something else that's odd which I should've mentioned: After the shutdowns - the battery is at 0% (shown via the side-lights and eventually ~4% or so after booting) - so its like I'll be plugged in, running off AC power fine, then all of a sudden something fails, voltage drop(?), computer shuts down - and then oddly I'm able to charge back up again after booting, from 0. So... maybe something is weird with the way the computer is talking to the battery. As I said, I replaced the battery, but this new battery reporting a healthy state is occasionally doing the same thing.

@breathlungs - Focus in on the CPU heat sink! While the PCH chip also needs a heat sink it's not the one thats likely getting pushed here.
If the charger/battery is an issue download this gem of an App to see things more clearly with the power aspects CoconutBattery lets get a snapshot of it as well.
