wierd water cooling problem

I am trying water cooling for the first time and something weird is happening. My loop is working fine and I am using a T-line to fill it. It is full and almost bubble free however when I turn the pump off the water level rises a little bit in the filling tube. Does anyone know why the water level might rise when I turn the pump off?

1. When the pump is on, something is expanding in volume a little. NORMAL for plastics and tubing.

2. Water is not compressible (let's accept that for a moment) but there is some note from you that it's almost bubble free so any bubble can be compressed.

Are you fretting over this a bit too much? I mean, does it work?

Well the loop is "working" but it is also not cooling very well. In fact it is cooling the same as my air setup. The water coming out of the radiator feels just as hot as the water going in. Might this be due to air bubbles?

It's the heat connection from the CPU to the whatever it is parts. Remember there are no part numbers, pictures or numbers here. One member had a CPU at 30C and was concerned when a new cooler didn't make it cooler. Hard to tell them it was fine.

My load temp on both air and cooling is 61C 2which is hot for a phenom II. I am using an OCZ Hydroflow CPUblock, a Swiftech 120mm fan, and my pump is a DangerDen CPX Pro. My old air cooler was a Coolermaster Hyper 212 Plus. I don't think it is the connection to the waterblock because it feels hot which would imply that heat is being transferred.

NO PICTURES means no one can check your work. If the water is getting to 61C then it's the cooler portion that needs work. Basic understanding of heat transfer is needed. But no pictures means folk can only guess the water is hot but the cooler is not where air can flow.
