Having trouble bleeding my loop

Reality|Bites · 7 Dec 2017 at 16:02

So I recently built a new loop and i'm having trouble shifting a huge bubble that's trapped in the tubing that comes from the CPU block into the top radiator. The bubble goes into the rad when the pump is on but I don't think it goes far as when you turn it off and lay the system on it's side it comes back out again. This is making the system unable to play games as the GPU temp just rises and rises until the GPU cuts out but the system is still running.
I've tried tilting in every direction but it just won't move. So I thought I would just drain the loop and try again, but the loop won't drain.
I've attached a drain port to the inlet of the pump, when I open the tap all it does is empty the reservoir and that's it.

My loop order is as follows res/pump > GPU > CPU > top rad > front rad > res/pump

Can anyone help me?

Well I've had another bash at it today, it was like open heart surgery with a filled loop though, I've switched the order to res/pump > front rad > top rad > CPU > GPU > res/pump.
Is was a lot easier to bleed this way and I have no big bubbles in there now. GPU still starts to overheat though, but I've only done it in the past hour so maybe give it time? or do you think the GPU block
isn't mounted properly? It's idling at 22c but quickly shoots up to 60C+ before I bottle it and shut the game down,This is a game where in the previous water loop only hit 35-40C max.

I do have front and back fittings tubing come from the CPU into the GPU at the back then from the front into the res/pump.
I think i'm going to have to just drain it all again best I can and remove the GPU, then try to remove the water block, which will be hard as I've rounded a screw on the backplate (top left corner)
The try and unscrew the waterblock screws, which wouldn't budge last time I tried, I was only starting to round off those screws as well.

Yeah I've contacted EK and it'll be 22p a screw....plus shipping
Yeah i'm really peed off at the moment with it all, I waited so long to get my View 71 case, which looks lovely btw, and it's just not going to plan.
I have an XSPC crossflow 360 at the front and an RX360 up top.

I'll post it tomorrow, sick of looking at it tonight lol

I've only rounded the one screw on the backplate, it's in the corner so I managed to swivel the backplate round to give me access to the waterblock screws, but they were solid and wouldn't budge, I tried one of the 4 around the GPU core and it moved a little but not much, So I gave up and just turned it back again.
I think I might have warped the backplate slightly but it looks flat.
