I've had a fractal s36 in my system since 2018, the other day I came back into my room and the system had restarted (I have auto updates etc off).

I looked on event viewer which said the system rebooted unexpectedly so I decided to check the temps.

My idle temps are fine so I ran cinebench and basically straight away the cpu package went to 100 and core 1 and 3 went to 100 so I stopped cinebench.

I have applied thermal grizzly twice now to see if it help but I am still hitting 100c as before.

There is a little noise which I think is the pump.

My cpu was a delidded one from overclockers

Do you guys think my aio is dead, hardware monitor says cpu fan speed 2860 rpm

my specs
fractal r6
fractal s36
32GB corsair dominator
8700k clocked to 5GHz
980 NVME
1TB ssd
2TB wd
1080Ti gigabyte
seasonic m12 750w
 
have scrapped the overclock and loaded optimised defaults temps never went above 60 after running cinebench. So I am at a loss. Is my cpu going bad? how can the overclock now be too much for it?

AIO performance can degrade over time through evaporation. How long have you had the AIO and what temperatures were you getting in Cinebench with that overclock before? Have you got any WHEA errors in the event viewer and are you using Windows 11 and with the latest chipset driver?

Hiya Before I got the 100c I was getting 78c max when under stress from prime 95 cinebench was lower but cant remember what it was. I've had the AIO since 2018. The day it had rebooted when I was out of the room I checked event viewer and I had event id 6008 the system shutdown was unexpected.

I've taken the overclock off and loaded optimised defaults which clocks the cpu to 4.7 and my temps in prime and cinebech are both 58c I'm currently idling at 23c

It always says that it was unexpected no matter the reason for the reboot, that message doesn't tell you anything. I'd say run it at defaults and see if it happens again, but it's strange your AIO is not performing as it was (unless you changed overclock settings to something crazy or tried to replace thermal paste unsuccessfully or changed fan profile) and if it degrades further you should definitely get a replacement. Stock temperatures seem normal though.

It's also worth checking the Event Viewer for WHEA errors and Bugcheck (blue screen of death) errors because give you more of a clue as to what caused it to reboot. However, I know that sometimes it can be reboot without error but make sure you check it.
