5800X temps seem high

[Devrij]

So I swapped from a 2700X to a 5800X (great performance uplift, very happy), but man it runs hot. I have a 280mm AIO and it'll peak around 85C under sustained load. It idles at about 35C which is grand, but under even a small load (eg running a virus scan) it throws massive volts at the chip and temps will shoot up immediately to 75C. like 1.45V for these low load boosts. Sustained max load it'll be much less, but still.

Is this all normal or should I be reseating my cooler?

normal. Unfortunately, they run hot AF, Not exaggerating they're harder to keep cool than a 5950x lmao... I had one - my suggestion is undervolt it and slap some thermal grizzly it'll help

They are hot chips, but then they do perform. Can't remember what sort of temps I saw at default, but it was high. Running negative offset with curve optimiser and +150mhz, every core can hit 5ghz and it peaks just over 70 degrees typically on sustained benchmarking. Still hotter than I'm used to but an improvement.

Thanks, not just me then! I think -ve offset is the way forwards. I'll check out curve optimiser

As per other comments

the 5800xt is hot af, that's what happens when you throw 105w through a single zen chiplet.

Both the 5900x and 5950x run significantly cooler than the 5800x. For reference a stock 5950x on a 280mm you'd be looking at 65c instead of 85c

 

[Devrij]

yeah that makes sense. I just set curve optimiser to -10 and it still hit 90C in cinebench

Hmm, prime blend now more like 70C after 10 mins, and boosting to 4.6 on all cores. not too shabby.
