Hi all,
my 12900K reaches 85°C during rendering at 22°C ambient temp.

During summer ambient temp can go up to 32°C this means that my CPU should hipotetically reach 95°C during rendering.

Will I damage my CPU by rendering in summer?

H150i Elite LCD from Corsair. it's a 360mm AIO.

what does the spec says? what temp is considered safe?
make sure the pump is at max and turn the fans to max after 70-75C. see if that helps. if youre using the stock paste, replacing it with something highend will knock a couple C off. going push/pull will knock of a few more C.
spec is @100c it will start to throttle.

yes, its just toastier that we like. it will throttle at 100c and if it were to somehow exceed that a lot it will just shutdown.
what the rest of your set up like, case/fans etc?

three QL120 fans on the RAD as intake and 3 QL120 fans as exhaust.

So, I was helping someone elsewhere with an H150i and a 12900k seeing similar temperatures so I began with some reviews to see what they were seeing. I can't find it now but I recall one reviewer mentioning the Corsair AIO's having a "mounting pressure problem". I couldn't seem to find anything backing that up.

Either way, the guy I was helping ended up swapping out to an Arctic 360 and saw a 6-10C drop under load on the same system.

I'm using the right mounting kit, this should not be the case :)

shouldnt be but could be. different tolerances between oems and its happened before. people usually solve it with plastic washers on the back or replacing it.

those are pretty BUT only 41cfm. putting some proper speed fans on it will help, a lot.

I thought you were busy spamming various forums with rage about not being able to use your cpu due to lack of ddr5? Did you pay a scalper finally?

Have you checked the contact between the heatsink and IHS? I've seen several people complaining about bad contact on reddit.
By the way, where did you mound your radiator? Top of front?

Have you tried undervolting?

https://www.techpowerup.com/review/...er-lake-tested-at-various-power-limits/9.html

Sweet spot seems to be PL1/PL2=140W.
12900k would be wasted with a 140w PL and the voltage is still not that well optimized. I'm not sure why there's no major reviewer that covers this, but you can just set it to default 240w and use V/F to undervolt. Same performance + much lower temps and power consumption (240w drops to 170w). Stock voltage goes beyond 1.3v which is an extremely retarded decision by Intel when many people can run it at +/- 1.12v all core turbo.

I'm pretty sure that's only from recently manufactured chips, which can often run well at well over -200mV undervolt. The ones with older manufacturing dates can barely be undervolted. 100% silicon lottery.

done it, after adjusting the voltage that is crazy high at default settings my 12900K is perfectly stable and does not go over 75°C during rendering.

Do you guys have a guide to undervolting? Haven't done it myself on my 12700K yet, but does it still involve it to be a fixed voltage, even in lower clock speeds? Or am I uninformed? I thought undervolting since the Skylake era meant setting the voltage fixed?

I have a 12900k with a arctic cooling liquid freezer II 360 and i'm hitting 100c in handbrake encoding. I've gone over the install several times. It's easy and straightforward. I would have expected better temps from this AIO. I'm not overclocking and don't plan on it. I just do a lot of video encoding and want to keep the processor cool.
I have a MSI board so i'll have to research settings for it.

Check for a bios update, seems MSI has some aggresive settings in the earlier ones

I have. Nothing new there. Hopefully it will show up soon. But i've read and watched videos about it and it seems voltages are too high by default on the board and some tweaking will bring them and the temps down. I'll play around with it after work.

to much or to little pressure?

Too little pressure.
I think there's a problem with the Corsair H150i coolers.
I have an H150i with Corsair's LGA 1700 retrofit kit that I'm using with a 12900K and you can feel that the H150i isn't firmly fitting against the CPU.
I was able to lay my case down on its side and press the cooler down for now which significantly brought down temperatures, but I'm planning to switch to another brand's AiO in hopes that it will solve this problem.

thanks for reply ill give it a go as well might be worth swaping back in the older intel stand off since there bit shorter

I was considering doing the same thing even though Corsair STRONGLY advises against it. I was basically thinking that I'll just be very careful and only tight the thumb-nuts down by finger and not let a screwdriver touch them. I imagine that I should be able to feel when it's tight, but Corsair probably didn't want to risk people over-tightening them and accidentally made them too long.

With that said, I massively overpassed my processor and it appears to be fine right now with the Corsair LGA 1700 retrofit standoffs. I think there's so much paste in there now that it's properly conducting even though there are too big of gaps. Doesn't seem like a long term solution given that I can still pull the cooler away from the processor while it's tightened down :-\

Replacing my Corsair H150i with an Asus 360mm AiO fixed my overheating issues. I could see from the thermal paste pattern when I pulled the Corsair H150i off that it wasn't fully contacting the CPU's IHS.
  • Using a normal amount of thermal paste with the Corsair H150i had my CPU idling at 70℃ and easily hitting 100℃ on all cores with 100% utilization across all cores.
  • Using gobs of thermal paste on the Corsair H150i allowed the CPU to idle at 35℃ and typically hit 85℃ with all cores at 100% utilization, but it would still occasionally/rarely peak at 100℃.
  • With my new Asus 360mm AiO, the amount of thermal paste had no impact and it's now idling at 25℃ and peaking at 77℃ with all cores at 100% utilization (typically at 65℃).

That's a problem for the Corsair AiO with LGA 1700 and I see reports of this all over the internet. I think people are pasting normally with the Corsair and watching their system run terribly, taking off the AiO and pasting excessively and watching the system run reasonably well but still too hot, and then just accepting the results. Intel CPUs throttling is effective so I think people might not be realizing how much performance and stability they're leaving on the table with a Corsair AiO and LGA1700 retrofit kit at the moment. I’d also imagine very few people run their processors at 100% on all cores hard enough to cause instability given how good Intel’s throttling is.

This guy partially covers the problem I ran into here, but I also think this issue is somehow happening with LGA 1200 backplates & retention brackets when used with LGA 1700 standoffs:

the ASUS one come with all the mounting hardware needed for 12th gen? might have to do the same thing

right now im seeing idle temps ins the mid to high 20's but i get peaks to 80 in few things that hit all cores. and again 90ish in stuff like cina bench. and it does feel like contact issue because the heat it just not getting in to the coolent. might have pull 150 and change the paste see if that helps at all.

Yes, the Asus LGA 1700 ones come with all the proper mounting hardware and just works.

I've taken a closer look at the H150i hardware now that it's out my system and it looks like the problem might be that Corsair is sending the wrong LGA 1700 standoffs. I thought the LGA 1700 standoffs were supposed to be shorter than the LGA 1200 standoffs, but the LGA 1700 standoffs they sent me are taller. I wonder now whether the H150i would have worked if I had just used the LGA 1200 standoffs I already had.

The Corsair LGA 1200 standoff is on the left and the Corsair LGA 1700 retrofit standoff is on the right:
IMG_2885.jpg


I thought the stack height of LGA 1700 was supposed to be less than LGA 1200 so shouldn't it also have shorter standoffs?
Does anyone know if this makes sense?

I was able to run reasonably cool while x265 ffmpeg rendering at 79C with stock clocks and even cooler with an undervolt (70C-75C) with the Asus AiO.

With that said, I use my PC for both Gaming and Rendering so I wanted to go a little faster. I need the machine to be stable for both though and that meant it needs to be able to run at its all-core frequency completely stable for weeks straight and at its peak frequency without any crashes for games.

Below is where I ended up for a stable overclock with the ROG Ryujin II 360 cooler on my mediocre SP83 12900K. I assume I could get the system to be a little faster and/or a little cooler by dialing in per-core voltages (likely through V/F curves), but I just don't have the time for that level of tinkering right now:

I doubt that's it. The reason they're taller is that the 1700 retension mechanism puts too much pressure on the IHS (in certain areas). Google the 1700 washer mod. I suspect that's why it's taller but don't quote me on that. I don't know why you had trouble with it but not the Asus - I don't think the Asus CLC is particularly better than any other CLC - although, I don't know much about theirs. It could be just coincidence - maybe the thermal paste was applied better when you mounted the Asus CLC? I dunno. If there's an issue with Corsair AIOs and Alder Lake builds - I don't know about it.

I was planning on trying the washer mod - I think Intel really dropped the ball with their design and won't concede anything about that. People are on their own to solve temp issues - (if) relating to the retension mechanism.
My bet would be that is/was your issue - 90-100 degrees is too much - just rendering? I don't think it should be that much. Even the 12900K - I would suspect 75-85 degrees, tops - but, I haven't investigated pushing that chip.

It definitely wasn't thermal paste application. I wrote in this thread about how I had applied thermal paste multiple times in different ways with the Corsair AiO and the results were hopeless. Switching to the Asus AiO resulted in a massive drop in temperatures with the same thermal paste application method.

Okay. I also think I misread your posts - the 1700 standoffs are apparently lower than the 1200 - which doesn't make sense to me. However, if you check reddit - many Corsair AIO owners claim the new 1700 parts are the same as the 115x/1366 screws. Many discuss the temps of their Alder Lake chips including 12900k. The Corsairs seem to run ok.

No. 1151 was shorter and 1700 taller.
