12900K are these temps normal?

jammir · 9 May 2022 at 11:45

watercooled 12900k 360 rad at stock hitting 74c, all P core overclock to 5.1ghz hitting 90c and at 5.2ghz throttling at 100c. I've remounted the block a few times always same sort of result.

Bent CPU?, or bent/flexing board? It's a pretty common issue on the LGA1700 socket and CPU's.

Are those temps gaming or stress testing?

Stress test gpu isnt installed yet for in game testing but played a bit of GTAV on the IGPU and temps were near the 70c mark at 900p low

checked cpu in the socket with a flat edge and seems good and the motherboard is crazy rigid to have any issues asus z690 extreme.

So what kind of volts you on at 5.1/5.2ghz? Can you lower and get stable? More aggressive fan curve on aio?

I get similar temps watercooled with a 9x120 external rad. 95 max on 1 core @5.1ghz all core. About 10-12 degrees between the best and worst pcore.

At 5.1ghz AI optimiser had the vcore quite high so was using 260 watts.

5.2ghz all core went crazy and was using 370 watts. Temps were hitting 110+ degrees.

Gaming is fine though, worst I've seen is 60-70 degrees.

1.265 any less and it would crash in a strange way all usb devices would get glitchy.

Can run at 5.0ghz at 1.185vcore but temps still 76c under full load, not sure how it's gonna be in a closed case but mu room is hot atm around 26c

Do you have a gpu in that loop? I'm only planing on running 1x xe360 and 1x pe360 for both cpu and 3080ti

Yeah I have a gpu but that was a Cinebench run so wasn't in use.

Bigger issue is the STIM/ board flexing/ flatness of the IHS etc causing these CPUs to run so hot.
The GPU stays in the 40's so loop isn't as issue.

the hwinfo screenshot, is that at 5.2?? either way look at the power usage, 340W, you have a high leakage cpu. More cooling is required to push further.

Stock at 74 seems pretty good, no? Ramping up the speed on these just consumes tons of power. Not convinced it’s worth it IMO…
