Air bubble in CPU waterblock

[beardyweirdy]

Hi
As per the title; I have finished a new build and I have an air bubble at the top of the CPU block. Any idea of how to get rid. I have tried rocking the case but it's not for moving
Thanks

Tip the case on it's side carefully and line the bubble up with one of the outlets so it goes up a pipe towards res?

Squeeze the tube until you get it down into the res.

If you have a d5 try adjusting the speed from min to max a few times, it might shift it.

Hi
Thanks for the replies; re squeezing the tube, is this done with the system on or off?

Cheers

I would say off as it would be easier with less pressure in the tubes - I might be wrong though!

 

[dave_beast]

Maybe with the pump on but system off would be ideal.

I do it with the system on. Completely up to you though. Best with pressure going through the tubes so it shifts them easier.

Hi Thanks for the replies guys.
I tried a few things last night and the bubble has diminished to around 1/2 its original size. It is now around 4mm long and 1mm wide. I did some benching and CPU didn't get past 50c (At idle CPU is around 20 - 28) and my 6990 and 6970 didn't go above 50 (they idle at 28), so I am assuming it is not too detrimental - what do you think?

The only thing I find strange is that the temp of the CPU fluctuates every couple of seconds so it will be 19...22...28...than back down to say 24. It never gets above 30 at idle, but does this fluctuation seem normal? I wondered about reapplying Thermal paste to CPU?

Thanks

Your CPU is probably under slight load when you're seeing the temp fluctuations.

while pc is on i tend to rock it from side to side gentry to get rid of all my bubbles.
