New build: i9-12900k, Asus Z690-i, 32GB Vengeance DDR5 4800mhz, Asus TUF 3080 OC, H115i Pro XT (with the LGA1700 standoffs), tucked nicely into a ssupd meshilicious. All stock, no overclock (except for the factory OC in the 3080). iCue fans and pump on Balanced. I've been working with PCs since the 90s, but this is my first water-cooled system, so I could be missing something obvious.
At idle the CPU reads about 27C-30C, iCue shows coolant temp at 25C, and ambient is about 22C.
Prime95 causes throttling and a reset in just a few minutes. HWinfo logs show core temps jumping immediately into the 60s (fine) and climbing (not fine). The first throttling entry comes after about two minutes with some cores hitting 100C, and then the system resets. iCue shows a coolant temp of just 27 or 28C.
I have tried re-seating the pump block. I used Kryonaut paste, not too much.
What else can I try? What should I test? What other info would be helpful?
Thanks in advance.

I know what is causing all of this. Its H1151 1200 socket bracket post are too long and is causing the standoff to have play in it so its loose and the heat sink is pulling away from the chip surface, I just did a system today and I am using a H115i Pro XT (with the LGA1700 standoffs) But its the back plate thats the issue. It needs to be shimmed under it to keep it from sticking up to high on the top side of the motherboard.. so when you put the LGA1700 standoff bolts its tight to the board. Corsair you need to add nylon washers in that kit to put on the back of the motherboard. or people are going to burn up there high dollar cpus and also cause a fire in their house.
