Aqua computer 295x2 block….

dont know about the leak but those VRM pads are not on the card correctly either.. to stop the vrms overheating, also the plx chip should not need any thermal pads on it as the heatsink touches it when placed down all that was needed was thermal paste on top, and i also see you put thermal paste on the memory chips, those required thermal pads and not thermal paste.
who assembled the card cause it looks like it was assembled wrong.

------------------

very unlucky though and i noticed some of the chips that have no thermal pad on requres thermal pads on them or risk overheating i dont see any on those ...

----

best thing i can advise to try to get that card working again is to strip it right down and stick the pcb in a air tight bag of rice, leave for 2 nights in a airing cubert or boiler room then after that test it if not working place the pcb in the oven pre heat to 100c and leave it in there for 15 minutes.
then take out let it cool down for 40 minutes, reassemble and try the card good luck.

Good thing it's coloured fluid though. Easier to see and wipe off where it's spilled.

If it's any comfort my old 4870x2 had red fluid all over it. Still works after 6 years.
 
I followed the instructions for installing the water block in terms of paste and pads, it was very specific i.e. thermal paste on the ram.

Did all the usual testing, looks like one of two things happened -
1. The connector where the tubes go in leaked underneath and onto the card
2. The block itself is leaking through screw connectors

I suspect the first one. I ran without power for a couple of hours but it seems it was a very slow leak going on to the card, obviously couldn't see this. Powering up I had various (obviously) issues finally found rubbing a kitchen paper towel underneath where the tubes go in underneath came away with traces of fluid.

Immediately powered off and took apart to see the above :( It certainly seems the card is dead after a thorough drying out.
 
I feel sorry for you, try to get some isopropyl alcohol to clean the card, install the reference cooler back and test it.

If I'm not wrong, Aquacomputer blocks uses thermal paste on memories and pads on VRMs (at least the Gtx Titan/780 is like that), I think his pads and thermal paste are ok.

Those o-rings on the terminal block are a pita, I suspect one wasn't sat correctly on install.

Either lightly dampen the o-rings before fitting, or if you have it, a light coat of silicone grease to hold them firmly in place.
 
The o-rings where on and visually looked fine, like I said it must have an incredible slow leak so I'm not 100% it isn't something on the block. But again that looks fine apart from the fluid pooling in the screw recesses but that could just be the lowest point when I turned it over.

But I certainly be taking pgi's advice next, in fact I'll run the block without the GPU to be 100% sure. But I've watercooled at least 6 blocks previously and never had any problems, sods law eh? :(
