Ahh... I see it now...

Yeah you are going to have to keep the pump input line below water level. Not a big deal really although right now it will require removing the liquid from the loop. With a big daddy pump in your last pictures I would not think it would be a big deal as long as you prime the feed line. But... bleeding would be tough.

If there is nothing coming out of the output, there is nothing going in the input. Pressure does not mean much if it is vapor locked by a big ole air bubble...


In theory....


if you have about 3-4' of intake hose inside the cooler... fill it... put your thumb over the end of it... put it all back in the cooler under the water... power up the pump wait a second or two and remove your thumb.. this should provide enough liquid to keep the circuit going.

Not a water cooling guy, but do have some experience with pumps.

you could also use a small pump to prime the feed line for the big one until the loop is bled (should only have to do it first start up...)

It's not that easy...the instant the hose goes into the chiller it is frozen like stone. I have my pump below the water line, way below, and I just cannot get the air out of the return line. I need to get another diaphragm pump I think. Wasting days.

Yeah the pump is below the waterline but you probably have a big old air pocket in the feedline since it has to go up from the res.

You should try getting everything setup BEFORE running the chiller (bleeding especially )

Got it!!!

That awesome SureFlow diaphragm pump I thought I ruined by running on 5v works fine. My coolant just happened to be freezing up at the same time my pump "died", so it seemed to not be working right even on 12v...it was shutting down.

Anyways...I removed 3 gallons washer fluid and added 3 gallons pure Prestone antifreeze. I don't think it will be freezing up anymore. I saw the bath temp was down to -37c last time I chilled it, and it is better insulated now. I took care of the cold piping so it should be colder yet.

I would say 3rd time is a charm, but I tried 2 different pumps yesterday so I'm on the 4th attempt.

This pump will pump air, it doesn't care...it's bad-ass. Not even the slightest bit of hesitation.

Diaphragm pump is the key.

I'm expecting to see all zeros on the cpu and cores today, instead of just the cores.

I psyched to fire it up after I shower and eat.

Happy Sunday everyone.
