[Build Log] : Rebuilding My Loop with X-Fire 5850s and Universal GPU Block Love

post #1 of 10
Thread Starter 
A while back I picked up a second 5850, but up until now I haven't had time to put the second card on water. In addition to adding a second block I decided to reroute my water loop. This is what I was starting with:

So far I have broken down the old loop and flushed the radiators out with boiling distilled water. On the video cards I'm using two MCW60s in conjunction with universal heat sinks. Earlier I had attempted to use the stock heat plate, as well as Swiftech vrm heat sinks, but neither methods prevented the vrms from overheating. On my single card I have had great results using the universal heat sinks. The MCW60s are connected in parallel using Swiftech's SLI/Crossfire Bridge. Here is what I have so far:

I'm using an Enzotech Sapphire CPU block on my i7 930.

I bought one of bmaverick's pumps as well as the DIY sanyo controller upgrade board. It wasn't to hard to swap the boards, the hardest part was soldering the two wires next to the sanyo controller. It probably would've helped if I had a finer tip on my soldering iron. The green board is the original board that came with the pump.

Added new power, ground, and rpm wires:

Pump with heat-sink installed:

I'm going to put the XSPC restop back on, but the holes in the base of this pump are slightly too small for the screws. I'll pick up a drill bit tomorrow.

Made a quick trip to home depot to pickup some drill bits. After enlarging the hole, the res-top went on without issue.

The front Swiftech MCR320 in place.

I adjusted the length of the wires on all the fans and sleeved them.

For the PA120.3 I had to make a custom top bracket due to the abnormal hole spacing.

Testing the tube length with the front radiator.

Now I just need to get the second rad in and start leak testing!

Looks fabulous, nice work! thumb.gif

I recently put my dual XFX 5850's underwater so your build is of special interest to me, particularly how much you're overclocking your cards! What exact model are they and how much voltage are you pushing?

I have the same setup on my 6870's, and I am very happy with it. I have mine at 1020mhz with this setup. Looks good!thumb.gif

With a voltage of 1.22V I have a Core Clock of 910 Mhz and a Memory Clock of 1210 Mhz. They are XFX 5850s, one is standard and one black edition.

Sweet. My cards (reference design black edition 585A-ZNBC) have been getting great temps underwater so your example is tempting. What temps do your cards run at load? Mine have done great for nearly two years however and I'm a bit leery of frying them so soon after building my loop...

Normally they run in the high 30s with an ambient temp of about 20c. The highest I have ever seen the main card hit is 42c.
