Just installed loop, CPU overheating rapidly - Page 2

post #11 of 45
Did you run the pump and bleed/leak check the loop prior to firing up the computer?

Could be a bad CPU block mount, air trapped somewhere in the system, etc..

Sounds like the water is just sitting there, definitely check your flow.

Also I'm fairly sure the Rasa block labels an in/out. It's dark and the same color as the acetal, maybe you just missed it? I don't know for CERTAIN though.

also I'm pretty sure that it doesnt matter which port on your radiator is used for inlet or outlet. Either way the water will be doing the exact same thing in your rad. Unlike a block where it does matter sometimes.

Bleed the loop...it may only be air. Feel the radiator. If it does not feel warm to the touch, water flow is blocked to it.. jump the psu and turn the pump on and off rapidly...while gently tilting your case back and forth. Inlet/outlet doesn't matter on a radiator...nor does order with a single loop...res>pump>rad>cpu is fine.

A picture of your loop will help too.

There is no specific inlet or outlet on the rad and loop order will not cause this. Like others have mentioned, make sure that the block has been installed properly and also check if the pump is working.

The only thing that should be an issue here is the cpu block. The flow of the loop and anything of that matter should have been observed while bleading the loop.

You should do a flow test:
Disconnect the tubing from both sides of your rez and put the downstream side tube in a big jug, or a bath tub, or sink.
Put the upstream side of the pipe into a container and make a mark at 1 gallon.
Turn on the pump and count how long it takes to fill the container to the 1 gallon mark.

Thread Starter 
Appreciate all the help from everyone so far!

Lets try to keep this thread clean and dandy though, I'm just hope hoping to get this problem cleared ASAP. (:

Anyways, like I said just now, I am almost 100% sure that the CPU block mount isn't the problem.

However, I now do think that the air bubbles in my loop might be the issue. I do notice a rather substantial amount of air bubbles in my res (miniscule bubbles though). Would small air bubbles be the cause of this gigantic temp issue? I find it kinda hard to believe though.

What exactly is the proper bleeding method for a loop? Kind of a newbie in this area, so will need some advice.

Thanks once again!

This. The only thing that matters is that your res goes to the pump. other than that order is just preference or what ever is easier for you to do.

To be honest I'm not familiar with regular PC-based pumps but on my pond pump pinching and releasing the tubing helps dislodge air traps. Turning the pump on and off rapidly or slowly helps dislodge the air traps, and shaking the PC may dislodge air traps in the block/pump. (Shake with the pump off and on.)

Lets not break anything though.

could you perhaps install a air cooler on the cpu, that way the cpu wont overheat, thus allowing you to test the loop properly for flow, air bubbles etc? without having to trick the psu and such.
