Fixing the CPU overheating issue (12900KS) with a very easy fix

Hi,

 

So I recently upgraded my cpu to a i9 12900ks with z690 asus rog strix a motherboard and I decided to keep using my older 360mm aio (corsair h150i rgb xt pro). When I first installed the cpu and ran a cpu stresstest like cinbench r23 the package temp immediatly reached 100 C and the cpu was downclocking to 3 ghz to keep it self from melting. Now I know that my corsair h150i is slowly showing its age but I didn't think it would be that bad.

 

Soooooo, I opend up my case again and noticed that cooler of the cpu wasn't toucing the entire surface of the cpu because this aio wasn't meant to be used with lga 1700 socket. There was a small gap between the backplate of the aio and the screws that were holding the cooler, hence why it wasn't making enough contact with the cpu. So the way I managed to fix this issue without buying anything is that I simply put a few pieces of paper between the back of motherboard and the backplate of aio to increase the pressure and make sure there more contact between the cpu and the cooler.

 

The results ? I went from 100 C with thermalthrotteling down to 3ghz to a stable 5.2 C all P. Cores with 80 C package temps with stock voltage and no undervolting. I was even able to overclock the P cores to 5.3 ghz and the E cores to 4.2 ghz with no extra voltage. The in-game temprature is around 50- 55 C. It's also worth mentioning that I'm using lga 1700 brackets and custom 3000 rmp noctua fans on my h150i aio to achieve these results. And my cooling score went from 121 in the asus bios to 180 after the small aio moddification to the backplate of the aio.

 

Now my only question is if it's a safe long term solution with the few pieces of paper between the backplate ? (Look at the picture in the descripton) Or should I try to replace it with something else ?

There's a $6 kit from Corsair for that AIO btw. I'd just do that and get it right. Paper is fine for now but I'd rather have the correct hardware. The reason you have that gap is because the IHS is a different height on LGA 1700 than 115x/1200.

 

I'm not actually trying to be as grumpy as it seems.

I will find your mentions of Ikea or Gnome and I will /s post.

Why is the 5800x so hot?

I am using the LGA 1700 retrofit kit if that is what you mean. Or is there another kit for that specific corsair aio ? If so, mind saying where and how I can get that kit ?

I thought I had linked it, sorry.

Do you have that kit? If so, what direction are your standoffs pointed? One side of the threads are longer than the other.

It looks like they want the long set of threads pointing up and towards the you when looking at the socket. If you've got them on backwards you probably can't tighten them enough.

I see that might be the issue there, I will look into it, thanks 👍

Great improvising though! Hopefully that's all it is.
