Watercooling a 5900 Ultra

[Tomvill]

I would like to watercool the GPU on my 5900 ultra as it gets pretty hot when i benchmark. I,m not going for the records or anything but i would like to increase my scores I,m thinking of using something like this http://www.xtremesystems.org/modules.php?op=modload&name=Seviews&file=index&req=showcontent&id=28 and it will be used to only cool the GPU the cpu cooling is looked after . The rad and pump look fine for what i want but i,m not sure about swiftech blocks because i,ll be buying the components seperately cause i don,t need the cpu block. Question: are there better GPU blocks for my video card and what would you think the increase in performance would be. Right now i can pull 7,220 in 3D-03 and over 20,000 in 3D-01. Thanks

Regarding the W/C Kit, I'd suggest you change the Rad to a 120mm single Rad or even a 2 x 120mm Rad. The 80mm is too small IMO. Cause you are going to be using for Cpu and Gpu blocks. If you were running two 80mm in // it might be better. But I still go for a 120mm Rad instead.

As for the GPU Blocks there is also DD's Maze 4 Gpu block.

I am currently using a Swiftech MCW50 Gpu Block. You need to know a few things for the Swiftech MCW50. If you got a FX 5800 and above card, you need to get/buy the FX Adaptor Kit. Bottom Left of the Pic.

Which looks like this after you set up on your FX card.

Now about W/Cing the FX card. I had a club 3D FX5800. Not bad card. Was doing 500/1000 Core/Memory. After I install the Gpu Block, I was like Hell Yeah! :banana: But as I pushed the Core, at 520 the 3D Mark started to drop. I was like What The F!! The more I pushed the more the Score fell.
Thermal Throtting! nVIDIA has installed it on it's FX card to protect from frying the chips. Which kicked in. So you might not be able to pushed too much.

No the watercooling is for the video card only I have something else for the CPU . I hope to improve the 521 clock and 940 on the ram with the water cooling for some reason Nvidia has set the thermal throttle at an incredibly high default of 120 C on the MSI 5900 Ultra but it must be kicking in lower than that I just cann,t see it being that high and i cann,t adjust it. Thanks for the info on the adapter kit if i buy the swiftech and i did change my mind and ordered a larger rad that takes a single 120 mm fan just to help make it future proof, but i did order the pump that was in that kit and i,m looking at variouse GPU blocks. Not a huge selection in Canada any good ideas on a GPU block for a 5900 Ultra

That's a good pump. It's swiftech's new MCP600 Inline pump. Honestly man I don't think you will be able to push the Core/Memory even with W/Cing your Gpu. Cause the Thermal Throttling is a Freakin pain in the butt. As I mentioned after 520 Core the Scores start dropping. I even hit 540 but the Score was lower then 500 core Score. With a Gpu block there is no doubt that you can push high but Thermal Throttling in gonna kick in man. I suspect that it's at 60C and not 120C. I tried searching forums for any Mod to disable the Thermal Throttling. but no luck.
How about DD's Maze 4 Gpu Block (http://www.dangerden.com/mall/Blocks/maze4gpu.asp)?
