Haven't watercooled in a while
Ok, so I scored a Mountain Mods case from Zoot (thanks!!)...
I also have a Koolance pump/reservoir...

I have a dual 120mm rad and fans.

They system is in the sig...

First question: How important is a full coverage waterblock for the GPU? Would one of these be good enough? (x2, one for each card, obviously!!)
NCIX.com - Buy Swiftech GTX200 Full Cover Heatsink for Use with Water Block Cooled GTX 280 & 260 Video Card - GTX200-HS In Canada.

(keep in mind the system is SLI)...

Which waterblock would you use for the GPUs?

What about the CPU?

What else do I need with this stuff?

I know I need some liquid and tygon, but what else is there?

Oh, and I don't plan to do any CRAZY overclocking....just mild...but I figure hey, the watercooling stuff (so far) is free, if I throw a couple hundred bucks at it, it's worth it (not for the $600 I had figured before!)

I wouldn't use anything koolance in a serious water loop.

That pump will not handle a cpu block and dual gpu blocks. Also the link you rprivided for the gpu blocks is only a heatsink. You are missing the actual block.

You'll need:

PA120.2 as a minimum, probably a PA120.3 rad
tubing - primochill is pretty good
liquid - same
barbs, 3/8". I will never use 1/2" again.
I use the Danger Den Tieton FC block for my 260. Very efficient, 100% load and 47C.

Do you happen to know the model number of that Koolance unit? There's an older one with a crappy dual-pump setup that really didn't do much, and the newer unit, which actually uses a DDC-type pump in it, which would probably be just fine for your purposes. If you do use that unit, what are the outputs on it? If they're compression fittings, your tubing needs to have the correct inside diameter AND correct otuside diameter, if you want things to seal properly. For liquid, just get some distilled water from your local store, and add some biocide (a drop of PT_Nuke, for example).

Also a big fan of the DD Tieton FC blocks, and as a bonus, they're very low restriction. If you go with that Swiftech heatsink, I'd pair it either with the DTek Fuzion GFX V2, or the MCW-60 (either the original or the revision 2), but you might also have to spring for an adaptor plate. It adds up, so do the math beforehand. Full-cover might wind up being both cheaper and simpler.

Koolance with a DDC pump in it? I did not know that.

MpG February 17, 2009 08:32 PM

They switched over a while back. Older systems like the Exos-2 used the crappy dual-pump setup, whereas newer systems like the Exos-2 LX started using the DDC. For awhile, if you looked at their system descriptions, if they advertise a 'new pump' with three times the power of the old one, that's what they're talking about. Basically, they just shoe-horned in a stock DDC 3.2 (their number for it is the PMP-400), which is actually pretty decent. Even a speed-control option in some setups, apparently. Although I can't imagine there'd be much room for vibration isolation.

great info guys...
This is supposed to be a kick ass pump...but I really don't know.
this is the pump that's inside of it:
Pump, PMP-400 [10mm, 3/8" ID] - Water cooling systems, pc liquid cooling kit, cpu, video card, hard drive
is it good enough?
And yes, there's a speed control on the back of this one...

I'll make sure to get the right size tubing and barbs etc etc.

What's the REAL benefit of a full coverage GPU block vs a regular one with ramsinks?

3.0charlie February 17, 2009 08:36 PM

Efficiency at removing the heatload from the memory chips. And no fear of any ramsinks becoming unglued...

Looks like you have the correct pump in it. All depends now is what type of connection you got back there.

I'm not sure...I'll post a pic tomorrow, maybe someone can shed some light on this for me!
Thanks for all the help guys!

Here's the pump/reservoir

Can you tell by the pic what size barbs they are?
