Hehe, yap, priming in this configuration takes some creativity. Submerging the pump in the bath is the easiest route. But if you can't/don't have a submersible, you can backfill the line and clamp it.

So, if you're config goes: Chiller bath >>>>>>>> pump >>>>>>>>>>> cpu
then you remove the intake from teh block and backfill the line all the way to the Chiller bath using a funnel. Then you take a clamp and pinch off the line. Attach intake back onto block, turn on pump and un-clamp tube at the same time to get the coolant running thru the loop till its all good.

OK maybe try the latter. I don't think the pump is submersible.

So this morning I look at the board which I Dragon-Skinned last night, and I see a couple small air pockets on the back-side of the board. Do I need to re-skin the back?

If they are close to the socket yeah, but if not I wouldn't worry about it....

Thanks for the quick reply FACE!

I didn't cover the entire board. I did about an 8-10" square on the back, and on the front I went from the top to the NB and the mosfets to the DIMMS. Does that sound like enough coverage for just chilling the cpu?

I'll probably redo the back and wipe it clean with alcohol first. I think I forgot to clean the back last night. OOps.

EDIT: and the plan was to go chiller bath>cpu>pump>chiller bath.....you think it's ok to put the pump before the cpu because that would make things easier, but I think I'd lose/gain a couple degrees going through the pump on the way to the cpu. And it seems like it would flow better if it was just pouring out from the chiller directly to the cpu.

I would not redo the back ny - it will be just fine.

[ny_driver]

Already peeled it. It was a touch greasy underneath where the air pockets were.

Should I put some dielectric grease around the NB also?...It worries me a little being right next to the edge of the Dragon Skin.

Right now I am making a hold-down plate for my block insulation. Plywood will work fine.

I'm now very frustrated. I cannot get a configuration where I can get all the air out and get it primed. The problem is that my hoses are through the top of my chiller so air gets trapped almost to the end of the return hose.

I tried adding the reservoir right where the air gets trapped, but because it's not a closed loop the res continues to drain out. I know the pump is strong enough to go twice as far as it is.

I have the pump on top of the chiller in the feed line and that seems to work well, but not quite well enough. I'm so irritated with this right now. I started with the pump in the return line, but ended up with air trapped in the line between the cpu and the pump and the end of the return hose.

WTF shall I do next?
