Overheating circuit after pump failure

Got even more air out by tipping it on it's back, and wiggling it around a bit - still overheating in about 5 mins.

Pump is def the new one [got the old one back] and working [felt the vibration when only it was connected]

Guess the only thing left to do is a complete clear out.
 
had 2 xspc 750 bay pump/res die on me in 11 months.. i would steer clear of these.
just a personal choice after killing 1 x58 udr7 mobo due to the water boiling and ****ing out the g card seal..
and the 2nd time taking a gtx 295 with it
 
Try unscrewing the top radiator and standing it vertically with the barbs at the top, also wouldn't you have been better off fitting the 120mm radiator with the barbs at the top? try unscrewing that and just holding it 180degrees with the barbs at the top.

I'm not sure what else you can do besides dismantling and checking for aforementioned blockages, if that's the case everything else is futile.

I would say that air bubble (and maybe others like it) are a major blockage.

Maybe you could drop some contrasting food colouring in your reservoir and see how far round the loop it does / doesnt get.

Do you have a widget where you can run the pump without turning on the motherboard? I find them invaluable for bleeding the watercooling system - although standing around in the kitchen shaking a pc to get airbubbles may get you all sorts of insults from any bystanders.
 
The setup was as it came from the manufacturer. I did wonder why they didn't put all the rads at the top, but I'm new to this.

Going to get it completely checked out/dismantled - while I'd love to try it myself, the whole system cost over £2000, so I'm more than a little nervous of breaking it.

Would you recommend moving the 120rad to the 3rd socket at the top of the Obsidian? Or any benefit from changing around the sequence [maybe having a radiator between the cpu and gpu?]

I've previously assembled my own systems from scratch - and have to say that while you can clock the hell out of this system, I don't think it's worth the worry of dealing with water, and the price premium over aircooled.

I'd leave it where it is but turn it 180 with the barbs at the top so that any pockets of air will rise to the top and get pushed out and not get stuck.

I (personally) would do the loop as follows:

Res > CPU > 120mm > GPU > 240mm> Res

That way you don't have warm water sitting in the reservoir and unnecessarily heating up the pump.

You need to learn how to maintain it yourself really, it's dead easy if you use 1/2" barbs and 7/16" ID tubing like I do, you just heat the tubing up and stick it over he barbs for a tight fit, the hardest part I find it pulling the tubing off when I'm dismantling the loop the fit is that secure. :p

Ok - so it was supplied pre-watercooled - what warranty did you get on this kit?

Until you get the loop up and flowing again, you cant really use the PC - somethings gonna cook. And if the loop is blocked, then the pump could well burn out again.

Finally, which pump do you have? It may have a speed sensor wire on it you can connect to a motherboard header which will say what the current RPM of the pump is - I seem to remember my pump runs about 3600rpm.

EDIT: I'm also curious who sells a 2 grand watercooled system where the hose is held on with cableties :)
 
Does your pump make any noise, mines pretty noisy and makes a rattling sound (although its awaiting RMA). I only have mine in a CPU/Rad/Res loop and it seems really powerful, if the res isn't completely full I can see the water movement.
 
Warranty was one year parts, 3 years labour - but I live in Ireland, and the maker was in England. Not going to say who the maker was [have seen people shouted at in here before for that] but safe to say they're not OCZ.
Pump is the one which comes in an XSPC 750 dual bay - no sensor.
 
Not yet - have taken the advice here, and it's gone back for a full strip out and change of the circuit [to put a rad between the CPU and GPU]. Will update when I get it back [so the next watercooling numpty can avoid the same pitfalls]

Really appreciate all the replies/advice.
