Help with first water cooling system needed!

Phunky Phish · 15 Jul 2006 at 17:43

Right... I have bought most of my kit and hacked my case ready to fit it but need some advice and help now!

My loop is-
Laing DDC-1plus pump with plexi glass res >
Nexxos Pro II dual 120mm rad >
Danger Den TDX 775 CPU block >
Nexxos Pro I single 120mm rad >
Danger Den NV-78 rev 1.1 SLI GPU blocks >
pump

I will be running a Core 2 Duo E6600 2.4GHz CPU when its delivered!
Dual nvidia 7900GT's in SLI
All hosing is 1/2" tubing.
All fans and pump are run through a Nexus fan controller (dual rad fans link so spin same speed) so I can control noise and cooling.
Dont know the mobo yet as SLI ready ones are not avaliable! Think will get a Asus or DFI when they get released!

If I had known that Intel had signed up with ATI I would have bought bloody crossfire gear! :mad:

Oh well!!!

Anyway, I have read that I should run the system for 24 hours or so without power to any components other than pump and fans to check for leaks, purge air etc.
But how to I get my PSU to power up without connecting it to the mobo :confused:

I have a Hiper Type R.

Any recommendations about loop, if its ok etc, and the PSU issue would be greatly recieved.

First off the rumour is that it is AMD who has bought ATI, not intel.

As for your loop it looks great apart from the fact you have 2 rads, Can't really see he point in that tbh m8. The nexxos pro dual should be ample.

Set your loop up roughly how it is going to be in the case and to leak test get a spare psu and on the 20 pin connector get a piece of spare wire, plug one end in the GREEN wire and the other end on a black wire.

See Here

Hope all goes well.

I thought Intel had signed an agreement with ATI for crossfire support?
AMD owning ATI should put a fly in the eye of Intel!

I dont have a spare PSU so I will just unplug eveything except power to pump and fans and then link the wires as described.

Cheers mate!

Oh, and put a second rad in the loop just to make sure it all stays nice and cool and low fans speeds to keep noise down!

I have a NZXT case which has a 120mm fan on the back anyway, so put the extra rad here. As for the dual 120mm fan rad, had to put the holes in the top as far forward as possible, then fill and sand the existing grill that the case has on it, and respray it all!

Have sprayed the inside pearl black (black with silver fleck), and have UV blue dyed coolant and 2x12" UV tubes, so should glow nicely!
My only problem now is have to get some right angle hose fittings as its all a bit tight in the small case! And this should sort the hose colapsing where it has to bend quickly!

Will post some pics when its up and running, then start my quest for OC heaven with the conroe and all that cooling!

Sounds like a nice modded setup. Just bear in mind though that the more right angles you have and the more blocks/rads, the more restriction you will have which will hinder flow.

Phunky Phish · 15 Jul 2006 at 19:05

Ah, never thought of that!

The loop will be-
Pump RH output >
RH input dual 120mm rad righ RH output >
Hi flow input CPU block Hi flow output >
Hi flow input 120mm rad Hi flow output >
Hi flow input GPU SLI coolers Hi flow output >
T piece (so I can fill system easily) >
Hi flow input pump

As the dual rad is at the top, and the single rad halfway down, with pump and res at the bottom I plan to lay it on its side to fill it first time, and purge as much air as possible. Then stand it up and losen the res cap to let air out and draw fluid from the now vertical tube from the T piece.

Sounds complicated but should be easy!!
I plan to tie wrap all hose/connectors to try and ensure a water tight fit!
Do you think the DDC-1Plus will be up to all this with dual rads and 3 RH fittings?

Cheers w3bbo for your advice mate.

I aint a WC expert by any means m8 and there are people on here far more informed than i am..just trying to lend a guy a hand with what I do know from reading other forums and help I have recieved/personal experience

The pump you have should be fine but the higher the restriction is, the lower the cooling power will be, so keep any restrcitions you have to a minimum for best effect. Saying that I have a low flow system and that works fine for me although I dont have GPU blocks. The only way to really tell is to try it out in different configurations.

GL with the build and post some pics when your done
