I've just been leak testing my 1st loop, part of which is an EK 5850 block. I noticed a leak coming from the top-side copper outlet. At first I thought it was the stop cap next to it and just tightened that, but more water kept pooling out and running under the gfx PCB. :o

I think I have figured out the problem, let me know if this is right:

you NEED to use those spacer things with the o-ring, they're not optional I assume? Because I didn't think the thread on my fitting was long enough to get in with the spacer underneath. I've removed the card and tried to get the fitting in with the spacer again, turns out it goes in fine with a little downward pressure, then you can screw it nice and tight to compress the o-rings.

I'm drying the card off now, hopefully it'll be alright? I'm using Nanoxia turboflow anti-corrosive.
 
you need the spacers to stop the barb threads blocking the flow of water through the block, if you remove the cap on the other side you can see how far the thread is going into the block
 
Im pretty sure the Orings are required to create a seal.

DO NOT USE THE CARD YET. It should be fine as long as it hasnt been turned on yet with liquid on it.
Make sure it is dried thoroughly, get as much of the liquid of gently that you can then put it somewhere safe and dry for a while like an airing cupboard. Ive heard people say leave it for a week to be sure.
You may want to finish leak testing before you dry it off though.
 
with long threaded barbs you'll need the spacers, generally with compression fittings they have shorter threads and won't require them
 
you really shouldn't need them... i've got the ek 5870 (and 5970) blocks, and they don't need the spacers, only if i use barbs.

have you got any PTFE tape?

also check that the o-rings aren't duffed

You need to use the spacers on the copper side which contacts the graphics card because if you look inside the threads are shorter on that side.
