Intel i7 12700KF with beefy AIO goes up to 100C, don't know what to do

Hello,

My system is running an Intel i7 12700KF cooled by a Corsair H150i Elite Capellix triple fan AIO water cooler. While running a CPU stress test with prime95 the CPU would sit nicely at 60-70C with all cores boosted to 4.9GHz using about 150W of power. however after a few minutes, temps shoot up to 95-100C with power going up to 250W, usually staying around 200-220W, and of course it throttles a bit down to 4.6GHz.
Anyone know what is happening ? I didn't expect these kinds of temps from such a beefy AIO. Why does power shoot up so much while the system could handle 4.9GHz @ 150W initially ? I made sure to purchase the LGA 1700 standoffs from Corsair and repasted the cpu twice, no luck... 

I noticed the coolant temp from the AIO's software is sitting at around 37C, doesn't that seem low when the CPU is boiling at 100C ?

I don't know what to try anymore, if anyone has any idea/info on this it'd be greatly appreciated. Maybe something I set up wrong in the bios ?

I have the AIO installed at the top of the case, pushing air from inside the case, through the radiator and out the top. Putting my hand under the fans i notice a lot of "splashback", air pushed back into the case. I read online that fans have a hard time pushing air through radiators and splashback insn't a big deal but it seemed quite exessive. I've attached pictures of the setup and recorded temp from HWmonitor (fans 1, 2 and 3 are the ones attached to the AIO).

 

Thanks !

Follow up : the 12700KF specs say that the max boost voltage should be 190W, how can mine be reaching 250+ ? 😅

try undervolting the cpu first then trouble shoot the CPU cooler because 1) it could be a defect 2) you might not have a good contact to the CPU

250 watts is going to be impossible to cool… my 10700k gets to about 220 and my custom loop starts to have issues keeping up. 
 

I would potentially check for updated BIOS, and then turn off whatever “auto overclocking” features the mobo likely has. It’s probably ignoring Intel spec and boosting to high with to much voltage. Or, try undervolting it.

Are you using MCE?

That is the only way my i9s us over 200 watts without an overclock.

So i looked at my bios, my motherboard is the Asus TUF gaming z690 plus, I have XMP 2 enabled (from my understanding this is required to reach my ram's full potential of 3600MHz) and AI Tuning off. there is an option called "oc tuner" but i have left it at "keep current settings", i don't think I have touched it before. I'm not sure why the power is so high though, like you all said, 250W is not normal at all.. Do you know what setting would affect this within the BIOS ?

I for one forgot to peel the plastic film from under the waterblock at first. 

Mistake anyone can make I think. That would probably explain low coolant temp. But it's probably something else.

As 250W load is too high for most coolers, even high end AIOs.

... you too 35?

Nothing short of a custom loop with 2x360 rads or more can cool 250W sustained, get into BIOS to limit PPT to 200W or limit boost duration

I have the 150i on a 10900kf 5.1 all core at 1.29v load voltage....it's difficult to keep cool for longer tests. That ends up being around 220w or so per hwinfo64.

 

Agree with the others, too much power

Yup that's Intel devilry, they make boost clocks that get their chips to the first place but that eats so much power no standard cooler can handle for more than 15 minutes...

It depends. Full power stress test isn't generally realistic day-to-day.

 

Gaming, normal rendering even, probably won't get you to the same as a stress test.

 

Think of it like transmissions. Normal transmission is mated to the engine power output for consumer car, it's not meant for racing. It can handle bursts load at regular driving but balls to the wall sustained is a different matter.

 

My setup will thermal throttle after maybe 30 minutes of sustained synthetic load, but will be perfectly fine for my actual use cases. So in that respect even throttling is "within spec"
