Water Cooling Loop High Temps

[Jeramathi1992]

Trying to come up with some ideas, CPU seems a tad hotter then should be around 50-60c under load. GPU is 40-50c, sometimes spikes to 80-90c.

 

Any ideas of the issue?

Started to have issues after changing to PEGT Hard Pipe and changed fluid to EK-CryoFuel Blood Red Concentrate 100 mL

if your GPU temps stay between 40 and 50c normally then spike up to 80-90c randomly... sounds like you have air bubbles trapped somewhere, likely in your GPU block.

Is there an easy way to get the air bubbles?

Or the a rad. Lightly shake or rotate your build while running

Cpu temps seem fine. But if the build just got filled again, prolly needs to be bleed properly. 

 

Putting the pump on max and tilting the rig tends to help. Also hearing the trickling of water would tell you air is in the rads.

I have an radiator mounted at the top, whats the best way to bleed it since the pump is at the bottom to output the air bubbles?

.... pump at max speed, tilt rig in each direction several times.

sometimes spikes to 80-90c? That sounds bad...
Does it go back to lower temps after some time? Sounds to me like the is no water flowing at that moment, but that should be just increasing over time and not jumping to 90°C.
