Hey guys im just curious how you guys go about draining out any air bubbles once you have put fluid in your system.
 
I put my d5 vario on its highest setting and remove anything not securely held down in my case. Disconect all psu cables other than the one going to the pump, then turn on the pump (bump start psu with paperclip) and rotate the case following the path of the air through each component starting from the pump outlet being careful not to suck any back into the loop once it reaches the res, i often detach the res so i can keep it upright and at the highest point in the loop to minimise this. Smaller bubbles will come out over the next few days, top up as needed :)
 
I used to use 2x T connectors, for fast and easy filling. just remember to plug one of them before turning the pump on :D

Shake the rad with the pump on, then just keep topping up the T line(s) until no more bubbles appear. This can take a few days to get it all out
 
As above, there really is no other way of getting the bubbles out other than rotating the components. Especially annoying when you get some stuck in the blocks themselves. Cases are quite heavy :P

Had better luck with pumps on slower too, otherwise mine tends to suck the bubbles straight back through from the reservoir once they return. Then you end up with tiny bubbles as it kind of blends them up :P

As bledd mentioned connector at the bottom for draining and one at the top for bleeding.

Alternative is to design the loop so that the reservoir is at the top of the loop.

:P Nothing beats a good shake for fast results.
 
My annoyance is that my radiator cooling fans are on top of the radiator but under the casing so its bloody difficult to get it all into position and I dont really want to be faffing around with shaking the radiator while the pc is on... I guess its not too much of an issue thinking of it.

I have bit of a wonky floorboard on the floor I could rock the pc to get the bubbles out... Seems to work anyway :p
 
I wouldn't suggest shaking a pc case if you have the other components plugged in or still in the case, can't see that being especially good for mechanical drives.
 
Well not so much shaking, if you just gently rotate the case around that'll usually do the trick. You can get the water-cooling running first without having the PC switched on, even less risk :)
 
just take out the CPU power connector, thats what Ive always done. The system powers on, but the main parts receive no power :)
