Hello there, lately ive been getting some overheating with my 7800X3D cooled by a FrostFlow 240 Series RGB High Performance Liquid Cooler (AMD)
Temps have been fine since i got the PC about 18 months ago but the last few weeks randomly the CPU temps hit 85-92C and stay there.
Normally before this issue for example on a map load or shader compiling it would hit 80 maybe 85 for a few seconds then i can hear the AIO fans kick in and temps go back to normal and never an issue.
I temporarily fixed it by giving the AIO cables a wiggle about as if there was a bubble or something and this fixes it for a number of days and temps cool way down only for it to happen again and again.
Its very annoying if i dont get to open case and wiggle the cables then it has lead to a crash on a few occasions.
But once i do give the cables a move everything is fine again for days.
Im convinced the AIO is acting up, i can se the pump is running all the time via monitoring software so its not the pump, there has to be something blocking , be it a bubble or whatever.
Since this is the first AIO ive used having always gone with air previously.
Is there anything i can do or do i just need to bin the AIO and get a good air cooler, anything good enough to cool a 7800X3D?

Thanks for reading.
 
Whilst PC is ok and running tip it up and around to see if you hear any bubbles move, with what your stating even if you are getting a RPM reading it sounds like it's faulty.
 
Yeah i can hear water motion when gaming [its always been pretty silent though] and when temps are fine when they are not all i hear is fan noise.
 
I'll second the thought it might be faulty AIO. Possible pump monetarily seizing and/or coolant loss. Fluid loss in 18 month old AIO on high wattage wattage is not an uncommon issue. AIO only hold about 100-200ml of coolant. Not as common as it used to be, but still not unheard of. I don't think FrostFlow has a coolant fill port.

Where is AIO rad mounted?

Does the "water motion" have a gurgling sound like air bubbles moving in it?

Tank on top of your radiator is higher than pump, so air should be caught in there. But just in case some air might be in pump, power up system so pump is running and as Glanza suggested try moving case so radiator is even higher above pump and lightly shake it. This shacking and moving might dislodge air bubbles out of pump.
 
Thanks again, ive done that there now while ingame of monster hunter wilds, temps have been fine since i gave tubes wobble yesterday when they got high so i guess its a wait and see scenario now.
 
from the photo it is plausible that air is gathering in either tube and blocking the coolant flow. Getting released when you wiggle.
but it would mean a lot of air is aready in the loop, unusual

try to arrange or tie tubes together so that it is a constant rise to radiator. Air in radiator is realtively fine.
