CPU at 100°C after hibernation.

[Simon xD]

Sometimes when I wake up my computer from hibernation my cpu's temperature spikes to 100° and stays there despite there being no load. (according to taskmanager)

 

System specs:

Win10

i7-7700K ( overclocked to 4.7 and watercooled)

rm750i

rtx2070

16gb ddr4 ballistix dual channel

 

I managed to save the log file from HWinfo before the system froze. (attached below)

 

Signing out and back into windows doesnt help.

Restarting does.

 

Even when stress testing the cpu or gaming I never temperatures that high.

 

Thanks.

Sounds like your system doesn't wake the pump back up after sleep. Not much you can do to fix that, other than ditching water-cooling or possibly getting a better mobo.

or.. not using hibernate on your desktop.

 

any idea if temps are actually that high, or if it's a sensor bug?

Check your watercooler. Hibernation should not ramp up the temps.

Does the fan taking power from the same heatsink fan header? If so, it should be the same with air cooler. Mobo faults?

Pumps draw more power than fans; it could be something to do with the current-requirements of the pump when the system is just waking up from sleep that causes something to go amiss and cause the mobo not to give it enough juice. Anyways, whatever the underlying cause it, it's obvious that the pump isn't running, which would definitely cause those temps and rebooting the system would cause BIOS to reset whatever went haywire and start giving the pump juice again, which again correlates with OP's explanation of the situation.

Thank you for your answers. I will check my pump the next time it happens and post here again.

The pump indeed wasnt running after startup however the LEDs on the AIO Pump were working. Thanks.
