It seems odd to me that this brand new, not cheap, system that many of us purchased would run too hot right out of the box. That Acer would sell a system that gets so hot that we're all out there trying to figure out how to cool it down. Acer has been around for a while now, I've got to assume they know that they're doing. I've done the same thing as others, in the end I just ended up repasting, and I get the same results. I don't think these high temps are because of bad pastes jobs.
This 10700 chip that I have automatically overclocks. Using a program called ThrottleStop I can disable this (seems to be the only way to disable it) and then the CPU never goes above 55C under heavy load. But without that disabled it easily reaches 100. From everything I've read, mostly in forum posts, these chips boost until they get too hot, then they back off until they can boost again. But there doesn't seem to be any consensus on if that's OK for the health of the chip in the long run.
I'm just going to roll with it and see what happens. It doesn't make sense that I'd have to take a blow dryer to the motherboard to replace a backing plate so I can install a custom cooling unit in a stock system that I just bought.
Thoughts?
