I had a leak in my loop so after i fixed that (which involved draining) i decided to put the acrylic block into my koolance 452x2 reservoir, since it said it improves performance and is compatible with the reservoir merging. I am using this reservoir with 2 pumps in serial.

When i turn turn it on no water moves and the pumps sound "unhappy". I tried shaking it, running it with fillcaps on and off.. Still same thing.

***?

Tries running with 1 pump only. P2 grinds p1 sounded like it was working.. However afboot i was greeted with 70c core temp.

I figure maybe that piece was for parallel operation or something, but the guide clearly says serial.

No one? I took the pumps out and both inlet areas had water. Idk what A clog might look like but i saw nothing odd. All water came out clear

When you fill your loop make sure you tip the entire computer on to its back so the reservoir is facing upwards. It is a million times easier to fill and bleed the loop that way and prevents bubbles being caught in the impeller of the pump.

If using dual pumps just use one to fill the loop too ... it will pump straight through the second no problem at all. That will stop the second pump from running with no water in it. Once it is filled you can start power to the second pump and bleeding air from the loop is a snap.

If a pump is grinding it is could be damaged, they grind when the impeller bearing has been worn down from running dry and the impeller starts to contact the pump wall and grind metal off.

Yeah tipping worked, thanks. Odd thbled and refilled it multiple times no issues whatsoever, and with that piece its a pain.

Unfortunately once i.got it filled it was still leaking.

Yeah series setup makes it a little more difficult because the only way air can escape from pump one is through pump 2.

Try to check the O ring condition and its placement of whatever device or fitting is leaking. Small leaks can be super frustrating, having to refill multiple times.

Yeah, sorry about the broken English. Swype is awful, it kept erasing my words lol.

I've refitted the leaky area 3 times. Its on the EK VGA Supremacy waterblock on a 7950.

The first time I had no idea it was leaking as I was so in awe at the temps. When I finally checked the case there was a LOT of water on the bottom. Unbelievably, no components touched..

The setup was 1 45* Bitspower Compression as intake, and a regular old barb fitting on the other. I couldnt tell which was leaking.

Second time, I realized I had the in and out on the waterblock wrong, so I fixed that. The 45* fitting appeared to be the source. At a point I had moved the rad intending to get bubbles out and it sprayed water everywhere. The fitting was tight, but I think it came from the area it swivels. I bought these off of a member here, I suppose they are defective :/

Third time, I used two barbs. Stupidly, this block can not hold two fittings + clamps + tubing side by side [So what other option is there?] Or, at least it cant with 1/2" by 3/4" tubing. I tried my best to clamp them both and they seemed to hold acceptably well. The in barb worked fine [so the block wasnt leaking there]. Out one seemed to have loosened from the block somehow and it was dripping from there.

Through setup 2 & 3, though, I notice I dont hear a turbulent water noise coming from the CPU block anymore. I used to hear it from the back of the mobo with 1 pump on setting 3+ and no VGA block. Now with 2 @ max, no sound. Is this just air bubbles? (I didnt check on the first functional setup that filled nicely, before I added in the blocker piece. I hope it was flowing well then? Otherwise something must be clogged?)
