The correct way to bleed a watercooling loop?

post #1 of 36
Thread Starter 
So I've heard many different ways to bleed a loop, I've tried running the pump with the res top off, shaking the case etc but air is still there.

When I turn the pump off, and then on again I can hear a funny noise and see the bubbles/foam going through the tubing.

I have a laing pump with a top so the res is at the bottom of my case.

Any advice please?

I've searched but most people just say "you need to bleed your loop" yeah well how do you bleed the damn loop

Oh and I've got my res filled right to the top is that right/ok?

Turn pump on for a while and then off. Tip the case front to back to move the air around. Turn pump back on run for a while. Turn pump off, tip case, etc. Some loops take more time than others, but letting it sit for a while will let the air form into larger bubble from the smaller ones and make it easier to push the entire bubble through the loop. Keep working on it, you will get it. I had on loop that took hours to bleed, but they will all generally bleed in time. Tipping the case to move the air where you want to will help alot. do that after you let it sit for a while.

Shaking will likely be counterproductive...

Thanks a lot for the reply.

I seem to have like about 3 of the smallest air bubbles and they just don't seem to move

Oh and by the way is it right to fill the res to the top?

Switch on the pump on and off for a bit during the filling process until a majority of the loop is filled with water. Then flip it on for a good 30-60 min usually gets the bubbles out. Just keep an eye on your res to check for water levels.

I usually unplug the mobo alltogether (both 24 pin & 12V connectors) and just hotwire the PSU ground pin to prevent any heat damage to cpu/gpus etc ; while turning the pump on and off a few times to fully prime the loop and then again while leak testing for an hour or so.

I set my loop up outside my case (after I nearly drowned my last computer) and after monitoring it for an hour or two, I topped the res off and let it run overnight.

Make sure to rotate the radiator, when I was bleeding my loop I had left the rad sitting flat on the ground, so when I picked it up to put it in my case a whole crapload of bubbles rushed out.

Basically tap the rad or tip it back and forth every so often.

When installing your loop you can add a fill and bleed port to make maintenance easier.

Just an fyi for the future

Thanks for all the replies guys.

My loop is installed in the case with all my parts.

I've got some bubbles up near the rad.

Does running with the res top off help? If so I'll leave it running?

Just so you know, I've had my pc on all day and night and there are still bubbles.
