55C is fine, but I would check the max temp with a synthetic bench like prime 95 or intel burn test.
Once you nail down the worst-case scenario temps, then you don't have to worry if one program or another will make your CPU too hot.
Ok thanks for the info, and would you happent o know, if when applying thermal paste, if I apply too much does that raise temps or does adding too much thermal paste not affect the CPU temps?
