FIrst Water cooled custom loop and I'm having a few pump concerns

[Candan]

Hey all

So I'm as far as filling the loop with water. This is my first ever custom loop and I went with hard tubing and no leaks! (so far!)

So... The pump drew some water in and filled most of the loop. Gurgle, gurgle

Now everything is full except the very last piece of pipe from the rad back to the reservoir/pump. You can see in the pic.

Now, I just don't know what's happening with the last section of air. It won't come out. The pump has been running for about 6 hours.

The water in the first section of pipe and the water in the reservoir is a little warm now, so this tells me that nothing is pumping. Actually, it's trickling inside the tube, but literally trickling...

I've rocked rolled, tipped and shook it. With the reservoir seal on and off. Nothing has helped.

Please help

I guess you took the liberty to take the block apart

Either that or I'm psychic. Probably the first one...

That's exactly what the problem was.

Once I turned the base plate to allow the pass over the fins. Upon refilling the loop, all the bubbles were sucked out like a vacuum and temps are now 28C idle and 50-55C under load.

Love it! Working as it should.
