CPU at 100c during full load

Is it okay that a 14700k runs at these temperatures when fully loaded? Idle temps are okay. I am using a 360 AIO so the only upgrade would be a custom loop.

Yeah, that's pretty expected. The 14700K draws a ton of power, and it's near impossible to cool. A contact frame helps if you can get one of those, same with undervolting, though don't expect temps to be in the low 70s under full synthetic loads as that's just not practical. 

 

Also don't use HWMonitor, that's pretty well known to have weird sensor readout errors with modern hardware. I doubt you're seeing that here, but you should still switch to HWInfo64 instead as that's much more reliable.

I'll just add that you're not really meant to run it under full load at all times. It's okay for it to momentarily reach to 100c, but if you're using it to do offline renders and such, then you need to enforce sufficient power limits.

 

Currently it shows that you're pulling 350-400w. That's your motherboard running free, and it's a bit useless to let it do that. You can give it the correctl core voltage. In games or any other general use that isn't 100% load, you should still be under 80c. I would always turn off multicore enhancement in bios, and adjust the LLC to something that doesn't feed the CPU with more voltage than needed so long as the system is stable. Even at stock while idle/light it should be pulling anything between 3w to 20w, and around 80w depending on the game you play.

 

Just in case you're building some sort of rig used for offline renders or such tasks that would put your CPU under 100% load for extended periods of time, I would apply a hard PL1 and PL2 limits of under 200w, or maybe under 180w, to make sure I'm running cooler for that extended time.

Thank you for the advice - the good thing is it stays very cool and uses very little power for most usage.
