Bubbles in loop

rabc1690 · 10 Mar 2013 at 00:30

Im still having problems with air locks in my loop to the extent where my GPU temps are sitting mid 60's a couple of mins into a game or bench.

what is the best way to remove air??

currently i have tried, tilting case back and forth, side to side, turning it upside down etc, switching on/off every ten secs or so for an hour at a time.

im currently leaving the thing runniong with the fill port cap off as ive read that this sometimes releases air. after this i am stuck as what to do next.

had this probolem earlier in the week but drained system to switch to a new case yesterday and last nuight and all today ive tried to get rid but no joy

Yeah i have a plexi front on my Full cover gpu block and ya can see all the air bubbles getting stuck in there when ya fill it, they get stuck against the fins over the GPU. I had to work them out by tilting the case and turning the pump on for short bursts to work the air around the card.

ive spent a total of 14 hours trying to get rid im pretty sure i have an air lock in the top rad which i cant get removed and ran out of ideas now. been tilting etc all day turning on off etc but no joy

Post a pic of the rig to see if there might be an underlying reason.

Which way is the loop pumping the water?

rabc1690 · 10 Mar 2013 at 05:30

res>cpu>120 rad>gpu>240mm rad> res. i have the xspc res/pump all in one

i would have went res,240,cpu,120,gpu,back to res and instead of going round the gpu go in front of it and use 90o fittings

I would have gone res/pump to 240 rad then to cpu simply to make it look cleaner/tidy.

There isn't anything obvious that should be causing a problem, stick the pump on full and shake/tilt/upside down violently to force the bubbles round to the res, keep triggering the pump. Some tiny bubbles will remain but will work there way out over the first week of use.

I doubt theyre stuck in teh top rad, they would be easy to get out if they were, to get air out of that top rad i would, lean the case down flat o the back of the mobo tray, lift the back of the case up a little, then lift the front of hte case up untill the case is resting on its rear panel, then tilt it onto its top/back corner, giv it a little shake or a blast of hte pump for a sec and that would get it out.

i dont know if your top rad has a bleed valve, my thermo chill has a lill screw at the back, which means i can just let all the air get trapped in the top rad, add some more water into my fill port at the bottom of the loop and the pressure pushes the air out of the bleed valve.

rabc1690 · 10 Mar 2013 at 19:33

no bleed valve mate, just speny aw night and half the day emptying and refilling to be presented with the same problem

ive tried that numerous times but no joy at all, i know there is def air stuck in there as my gpu temps are between 55-62 during gaming

when i emptied it out i went ras>240>gpu>120>cpu> res again

The rad at the rear of the case will be trapping air as it's mounted upside down. You'll need to turn the case upside down or flat to bleed it.

rabc1690 · 12 Mar 2013 at 08:56

cheers been tryin that as well but no luck whatsoever

Andy321 · 12 Mar 2013 at 20:29

How are the CPU temps? If there OK and its only the GPU temps that are on the higher side then like others have said, it would point to the 120mm rad as the problem, or possible a bad mount on the GPU block.

You have probably already tried, but you can try lying the case on it back with the PSU cable hanging over the edge of your desk or something. But I've personally never had to go that far to release trapped air.

What pump are you using?

rabc1690 · 12 Mar 2013 at 21:01

its the xspc 240 kit, temps are 52 max on gpu and 59 max cpu buth under load and i never really seem to get hot air from the rads blowing out and the rad never gets hot to touch
