9700k hitting 101c in Cinebench. Thoughts?

Name · 13 Mar 2023 at 17:32

Hello,
Thought id do my bi-monthly multi-core Cinebench test to see where my temps are at and they seem to be reaching nuclear levels. Running an i7 9700k @ 3.60Ghz + Same AIO untouched for 5 years:

Max temp: 102c
Avg temp: 94c
Desktop idle: 47c

I hear of Ryzen getting this hot but I think it might be time to reapply thermal paste? or replace AIO alltogether?

When my 4790k went that hot it was the AIO needing to be replaced... I'd try reapplying paste first but I'd go with time for a new cooler (or refill if you can) as the likely issue.

Is the pump working? You should feel a vibration if you put your finger on it when it's supposed to be on.

im not too sure if i can or not, the tubes definitely vibrate a little so i think the fluid is moving ok. CPU temps when gaming seem alright between 50-60c. Was just alarmed to see Prime95 and Cinebench hitting 100c within 3 seconds. Will keep an eye on things and update as necessary!

Wouldn't be too keen on replacing the AIO at this point as its new pc time next year. I'll make it limp over the line into 2024 if i have to

If your AIO is plugged into a fan/pump header you can normally see rpms being registered in hwmonitor, I know my ek one does.

If it has failed you could always pick up a cheap air cooler to tide you over...

it's not only the pump that can fail.
because the loop is mixed metal (copper block, aluminium radiator), deposits can clog up the fins on the block and there will be barely any flow within the loop
also, coolant evaporation...though might not be so much of an issue depending on how the radiator is mounted

my best guess considering that you still get okay-ish temps during gaming would be the fins getting clogged

1) thermal paste is cooked
2) AIO cpu cooler mounting has come loose
3) pump on AIO is cooked
4) fans on AIO is cooked
5) coolant inside the AIO is cooked
6) Case fans are cooked

Take your pick it's one of them
