(Mostly) Defiant CM690 Water Cooled GPU's

post #1 of 9
Thread Starter 
For a long time now I have named my most current computer Defiant, a name which I have lifted from the USS Defiant from Star Trek: DS9. Generally due to the fact that I always try to keep myself in the Mid-Tower category, while packing in a good healthy punch.

For a long time I never thought I would take the plunge into water cooling due to its initial start up cost, but earlier this year things just sort of fell in place. I had scored a set of Danger Den full cover blocks for my GTX480's for an unbeatable deal. From then I began to research just what would it take put them underwater, how large of a radiator would I need, what kind of pump. With a little bit of research and some time I found out what I needed.

At the same rate My CM-690 case, although a great mid-tower, lacked the free space to mount a large triple radiator. There was not a lot of room in-front of the PSU with a fan installed and the HDD bay's sitting there. One could hardly fit a small radiator on the inside of the case, and mounting one on the top meant losing the top cover. No there must be a way!

Well, I thought to myself. What could I do with out? I only one run optical, and one HDD, perhaps I can use my spare 5in-3.5in adapter and remove the HDD bay, that's good while I'm at it I can un-shroud the top fans, and give the whole inside of the case a good dull-coat black, enlargen the rear access port and add cable management routes!

Yes that will do nicely, now all I need to do is build a holder for my radiator. It's a good thing angle iron is cheep right?

Well, with out wasting to much more time here it is, 95% complete (waiting on Bulldozer!)

Specs:
AMD Phenom II X6 1100T @ 4140mhz
Gigabyte 990FXA-UD5
Kingston HyperX T1 @ 1840mhz
PNY GTX480's @ 850core/2000memory
Thermaltake TR-2 850W
Coolmaster CM690 (early version)
Zalman 9900Max 135mm Blue Led
Danger Den Full Copper Waterblocks
Phobya G-Changer 420
Switech MCP-655
150ml Cylinder Res

Thanks for looking

With a 25C Ambient I'm getting the following

Idle:
CPU 34C
GPUs 36C/35C
CPU Vregs 29C

Load @ 3600mhz / 800Core (low voltage OC)
CPU 43C
GPUs 51/51C
CPU Vregs 35C

Load: @ 4140mhz / 850core (Medium Voltage
CPU 55C
GPUs 56/56C
CPU Vregs 42C


About putting the CPU under water, I'm considering that with Bulldozer, as well as putting the Vreg's and Northbridge underwater as well.

Ghetto it is!

You hit the the nail on the head. I was thinking to myself "Man those power cords for the 480's look awful, how can I fix this?" The answer, Wire Conduit!

The 90 Degree barbs sure are what I had lieing around as I did not want to wait on some 90 degree fittings, but they were already automotive grade fittings I had, so I just used them!. The wire ties is just alittle bit of security It's not going to stop a blow off if that ever happens, but it will prevent the line from slipping on its own.

Thanks for dropping by.

Thing is, you dont 'need' the elbows. The bends wouldnt be that tight.

While true, I do not see anyone else using automotive elbows, and I do not see many people using ethylene glycol. Both of which I have in ample supply.

Fast computers and Fast vehicles. Tis two hobbys that break the wallet.
