I'm keeping a close eye on the temperatures with HWinfo, and so far I can see; no problem.
Benched it with Cinebench a couple of times, topped @ 80c wich is fine for a 7800x3d.
Idle it sits round 40c, also no issue.
From day one I have the errors in this build, maybe the temps will drop if the errors finally get resolved.
In that case it's a win from my point of view.
Ticket with Corsair has allready been opened january 4th, with "radio silence" since january 19th form their side.
