CPU Temps High After Swap To New Case...

[f1racer]

Hi All

Strange one... I've recently upgraded my PC and donated the older kit to my Son. I removed the Asus Motherboard, i7 9700K and Aorus 360mm AIO from the case and put it aside ready to go in the Son's new case. I never physically removed the AIO from the CPU, taking care not to pull the pipes etc. Now that everything is in his case, the 9700K is now running a lot hotter than before? When it was in my case, idle was 30-32c and load 55-65c tops. Now it idles at 50c and load 85-88c!!!? I removed the pump, cleaned of the thermal paste and re-applied, but still runs at these higher temps? Any tips on what else it could be etc?

Cases are:
Mine - Lian-Li 001 Dynamic XL
Son's - Lian-Li 001 Dynamic


Thanks.

All case/aio fans spinning?
Correct airflow setup of where air flows in and out?
Is the case in the exact same location?
Post a photo?

Yeah, all case/AIO fans spinning. Bottom 3 and side 3 fans are intake, top AIO is exhaust. Case is in his room... From cold start, as soon as Win11 is booted to desktop, CPU is idle at 50c?

Re-mount the CPU cooler.

Regarding location, i was thinking maybe it moved from wooden floor to carpet and maybe that meant bottom intakes were blocked. Prolly not that tho if its hot so fast.

More voltage in the cpu than before would be my next guess.

Tried tilting the case to let any air bubbles in the AIO shift? Listened closely for any gurgling?

did you mount the radiator the wrong way with trapped air in the wrong place?

Pump definitely running? Water block warm? Radiator warm?

Thanks for the pointers guys, i'll try these out at the weekend!

Pump may be boned, stick your ear to it or read the rpm somewhere.

I checked the pump tonight, on Balance its running at 2040rpm, Max at 2800rpm.... So that seems to be ok.
