The fruits of our labour. :toast:

Well guys I asked you lot for help with my watercooling rig and which components to go for for my system of X2 4800 and 2x7800 GTX.
A special thanks to Kris at this point.
In the end went with:

120.3 PA (3x120mm Silenx)
Swiftech Storm
2 x 1/2" Maze4 Acetal Top
AquaXtreme 50Z-DC12 Mag Drive Inline 12V Pump
T-Splitter
7/16" Tygon tubing

and the results?

Well lets just say I never expected the X2 to clock that greatly, nor the GTXs in SLI to do so well with all the heat that they and X2 puts out. I was in for a shock!

The fans are running on silent settings here via rheobus, showing what the PA can really do.

Here you go(and also worth pointing out that CPU1 is the weak link here, CPU0 will do over 3GHz at same volts):




These are the settings for the GTX that was able to go to and pass "Test Changes" within the control panel. they work fine on games etc. is it possible to overclock beyond these
speeds even though control panel wont test them as working? Obviously I want that 527 on core for the magic 27MHz steps but according to control panel its not achievable but is it?
Also are there any pencil mods for the 7800GTX? I dont have any decent soldering equipment for a voltmod though I have the skills having been a debug tech for a while a few years ago.

Looking good! 3Ghz on a DC setup with water is an excellent result! You can definately go higher with those GTX cards with some more volts. The 256MB cards can go as high as about 1.75-1.8v with watercooling and this will take you into the 600+ range on the ROP/Shader domain with a Geo in the 650-675 range. What are you idle/full load temps for those SLI'ed cards?

thanks Kris, you were definitely one of the stronger influences on me choosing that setup.
the GTXs idel @ 33C and load at 39C!
hmm voltmods, well i will need to source a better soldering iron for starters, what wattage do you suggest as a minimum, this 30W joke I have is useless. :p

[Sneaky]

you could probably drop the temps down a bit by getting some more powerful 120mm fans, but very nice results nonetheless

pombertot, about what voltage are you running the Silenx fans on? With anything less than 12v, I would imagine you'd be less than ~49 cfm for each fan (assuming Silenx fans are rated correctly.)

I only ask because it relates to a separate thread I posted.

Awesome results on a pretty much silent setup.

roughly about 5V through each one.

roughly about 5V through each one.

LOL - so about 20cfm with each fan then...if that.

Good job. Nice setup and results.

yep just shows how good the design of the PAs is and also that guy that designed the Storm knows his ass from his elbow.
has to be siklent, computer in bedroom, downloading 24/7 and wifey dont like no noise.

[mcbarnet007]

yay, just order myself the pa120.3 today. hope 50 dollars extra over the he120.3 is worth the money. I think I'll have exactly the same setup as you do but instead of Maze4 I have this old swiftech vga block

[fareastgq]

How is that masterkleer tubing? flexible like tygon or more like clearflex? Just wondering because I've never bought anything but tygon.
