I upgraded from a 2700X to a 3800X today, all other components remained the same.
I'm running a 240MM AIO water cooler on it, the same I was running on the 2700X.
On the 2700X I was idle (in bios) at 30C or below, and on cinebench R15 I was hitting low 60s when overclocking all cores to 4.2
On the 3800X I'm seeing 38-40C at idle (in bios) and 72C on cinebench R15.. STOCK.
Does it really just run this hot?! And before you say it I have redone the cooler/paste TWICE with no changes to the outcome, -that is not the problem-.
Ive seen a few other posts regarding this issue but most just end in speculation and "me too" but no real answers.
