Watercooled GPU

PSU died (I think)

****PSU problem further down -- Post 14****

I have a reference HD6950. Im just about to buy a waterblock for it, but was wondering whether my original backplate will fit or if I will need an EK one?

Depends entirely on the length of the supplied screws. I would have thought that the supplied mounting kit would allow for the original back plate, but I would check with someone with first hand experience. Which HD6950 is it?

Its the Sapphire 2GB reference.

Will 1lt of fluid be enough for a GPU, CPU, slim 280, normal 120 and say 1.5m of 1/2ID tubing? My maths isnt the best today

Yes see signature below. I used less than one litre.

and I think so. I have that block.

Rik1254 · 11 Apr 2012 at 21:53

Legend, very similar to how Im going to route it, so 1lt will be plenty. Thanks

I may have a photo of my GPU PCB if you want to check against yours for the Razor? I will drop it into my thread later this evening.

Thanks, bought anyway, can always return under DSR anyway.
Would be nice to see what the 6950 vs 6970 looks like mind.

I have just uploaded the PCB to my thread. Or:

Exactly the same

skylineboy · 12 Apr 2012 at 20:00

make sure you have every screw including those on the end. It takes a little bit of working. Check on YouTube.

Edited my post.....the minute I clicked post....it literally fell apart in my hand.

Rik1254 · 13 Apr 2012 at 13:33

Quick question, when applying the paste, same principle as cpu or is it more/ less?

skylineboy · 13 Apr 2012 at 18:53

I used same

Rik1254 · 13 Apr 2012 at 20:33

Right, just got everything set up, crossed the green and black (nothing else) and it worked fine. Flicked it on and off about 3 times (not quickly, about 10 seconds apart), I then filled it up fully and turned it on again and nothing.

Ive tried my other PSU (HX620) and that works, but it clicks, which Im not happy about.....am I doing something wrong?

pgi947 · 13 Apr 2012 at 20:42

Leave it running for a while and see if the clicking clears up, I freaked out when I first started my pump as it made a horrible clicking/grinding noise. Left it running and it soon cleared up, seemingly was down to air in the system.

skylineboy · 13 Apr 2012 at 20:49

exactly as above. make sure the pump always has water never run it dry. It should die down with the bubbles.

Rik1254 · 13 Apr 2012 at 21:10

Its the second PSU clicking though, its the first time its done this, been a constant runner in my HTPC for ages with no problems.....but what about the first PSU that died, its not like it was under any stress to overwhelm it.

Rik1254 · 13 Apr 2012 at 21:29

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO.....it must have had a little surge or something as its working fine now (I had this problem with my old Corsair unit before this one)....my friend who is a WC guru had a little look and said that 99% of the bubbles have gone, its the easiest rig he's ever done. Time to get it all set up, temp tested and pictured

.....longest 12 hours EVER

EDIT: Psu flopped again....its after every 3-4 times its flicked on and off...Ill put this into the general sub forum....more people reading, plus its not a WC problem any more.
