Loop finished, only one leak so far, no disaster...

Can I also suggest using kitchen towel rather than toilet paper. Toilet paper disolves and rips and is nasty. kitchen towel soaks up loads and doesn't rips so easily. Will be easier to clean up for you.
 
Well, we ran out of kitchen towel on Friday. Usually go to get some in the weekly shop but with weather conditions the way they were the missis didnt want to leave the house
 
I would drain until leak is fixed, wouldn't risk it tbh.

Oh by the way, have you checked the fitting to make sure the O-ring is present, I say this as I received a brand new unopened fitting once and no O-ring was with it, all the rest of my fittings came with them except that one, luckily I checked it before fitting and filling.

This, a leak is a leak no matter how small, eventually it'll just get worse. Definitely save yourself some heartache in the future by just fixing the leak before settling. Even if you have to disassemble your entire loop, if that's what it takes.
 
Great news about the leak - what advantage is there to parallel flow? I always assumed serial was better as - in parallel - any restriction in one of the blocks would cause most of the flow to go through the less restrictive one? The old argument about one card heating the other I thought was debunked years ago when it was shown that the overall heat-up across an entire loop was negligible? Has something changed in the newer blocks?
 
Looks a good setup in there.

Is that a sound card up top? I wish i had a x1 or x4 pci-e slot on top so i could do the same.

Oh and i have 6 ek angled couplings and none have leaked at all. :)
 
Ramped the voltage up to 1.1 this morning and ran a bench. Top card stayed at 50, bottom card shot up to 75. Flow between cards must have been borked in that parallel connection,. So ive stripped it down and took one of the connectors out. Now to leak test again.

So now the coolant goes into the top card, round the block, into the joint, round the block on the 2nd card, and then back to the pump.

This doesn't seemed to of solved the problem though. Bottom card still gets really hot in Heaven, probably +30C difference on higher voltages.
 
Flow path looks a lot better now.

What blocks did you fit to the cards? You should only have a difference of 1-3c over both cards.
 
hang on, you say the flow goes from the bottom card back to the pump, how exactly is your pipe work setup? as really the pump should be fed from a reservoir, and whats the T piece for from the bottom card?
