I guess I better grease it. How much of the board do I need to cover when just chilling the cpu?

Youre gonna skin the outer area of the cpu socket, front and back of the board. If you use grease in the socket, remember what spfoam said, not too much if its vicous because you dont' wanna bend the pins when clamping down the cpu fastener. You should only need to grease the socket and not the rest of the board since you have the skin to spread around the socket.

If you have closed cell foam, i'd cut out the square of the cpu h/s in a layer of paper towel and then cut out the shape of your waterblock base and lay that over the paper towel.

[Kal-EL]

Whatever method you choose, papertowel or foam, mount your block, bolt it down and then remove, check contact of the block and TIM spread to make sure the papertowel or foam isn't preventing good contact with the processor h/s

I can't imagine bending the pins once the cpu is seated in the socket. Thanks for the advice.

Now I'm wondering how I will prime the pump with no res to fill right before it. I don't want the pump before the cpu. I'll probably keep that little res right before the pump. What do you think of that idea?

[Kal-EL]

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.

[ny_driver]

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?

[FACE]

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

[ny_driver]

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.
