I seem to have a never ending supply of air in the system when I tilt the case, more always comes out the top of the two rads.

Is there an easy way to bleed this??


Looking at the below pic my 120rad has a screw on top, could this be used to bleed it??

Or am I just being impatient and I should give it a few days to work the air out?? :)
 
Still have an issue with air in the loop!?

From what I can tell, air is working it's way back to the res, but where the air/water is dumped back into the res the intake for the pump sits right opposite it so this is simply sucking the air straight back into the loop again.

I can see the bubbles hitting the res, then getting sucked in by the pump and away around the loop they go again.

Anyone got any ideas on this?
 
I took the res cap off while I shook mine (I didn't fill the res to the top (about 3/4's). This way air that came round the loop and there was lots of it, would just go out the top. I don't have my cap attatched now in case any air bubbles still find the way round.
 
You need to restrict flow whilst bleeding with that type of res. This will help stop air bubbles flying straight into the centre of the impeller rather than having a chance to rise to the top of the res. Pinch the tube with either your fingers or a clamp to bring the flow right down.
 
If you take the pc offline and only power up the water loop, like you would when leak testing, then stop, start, stop, start etc the power so that the bubbles are pushed around but then the power stops and they have time to rise in the res?

:)
 
Also thought I could put something in the res to deflect the flow of the bubbles so they're not sucked straight up by the impeller.

A bit of rigid foam might do the trick until all of the air is out.
 
I didn't mean lOng term, jUst to bleed it. A piece of plastic for example.

Oooh. Part of the box innards of a motherboard box, the top plastic cover.

If it was in long term I would say it would be an issue, but not for a few mins.

Well that has done the trick!

I cut a 2cm wide piece of plastic from some packaging.

Curved it into the res hole and covered the return on the res.

Give the case a good wiggle about and you could cleary see the bubbles going through the tubing into the res and out the top - not back into the loop again! :)

Some microbubbles in the tubing now that will work their own way out, but all the large air bubbles are finally gone!! - -I'll just let it run 24hr with the res cap off to aid the process.

STUPID design of a res tbh when it could easily be rectified with a slight partition build into it.

If it hadn't worked out I would have gone mental and looked for yet ANOTHER res option!
