6800GT Waterblocks?

What waterblocks are available for the GT? I know Danger Den makes one but its 125 and I don't have that kind of money right now. Does their MAZE4 fit? What other companies have them? Thanks. :D
 
Yes its good. I do not believe the Maze4 fits yet. You can mod it to fit, but its not perfect.
 
You can also use the Koolance GPU-180 block. Before I began to use the DD NV-68 I was using the Koolance one. It performs great and allowed me to reach 435MHZ easily. Even under stress testing from both Prime95 and the HDR demo, I never broke the 70 C mark.

Simple answer is, yes it is better. But it wasn't always better than the Koolance. What I mean by this is that when I had both the Koolance CPU block and the NV-68 in the same loop, the temp I was getting was actually worse than what I was getting with the Koolance CPU block + Koolance GPU block.

That's because the Koolance pump and radiator weren't adequate in dissipating the additional heat introduced by the BFG 6800 GT's core plus GDDR3.

Now that I've got the GT on its own loop with the DD NV-68, my temps on the CPU and the GPU have both improved.

*Before (Koolance CPU + Koolance GPU on same loop):
-CPU temp: Idle: 33-35 C, Load: 37-38 C
-GPU temp: Idle: 53-55 C, Load: 66 C

*Now (Koolance CPU and GT on different loops):
-CPU temp: Idle 28 C, Load 33 C
-GPU temp: Idle 48-50 C, Load: 62 C
 
Why are these GPU temps so lousy with H2O cooling? The CPU puts out more heat and it's cooler!

Do you know if this is because you simply needed a better pump and radiator to handle both, or does the DD NV-68 really require an isolated loop?
 
Thanks guys. I decided that since I'm really not planning to use the rest of the money in my bank account for a while that I'll go for the big guns and buy an NV-68 :D.
 
Don't EVER buy stuff like that from frozenCPU, they are way friggin' overpriced, picewatch/pricegrabber doesn't have it, but if you do a search or froogle, I noticed quite a few places have that block for around 37 bucks

Yea, I think I just needed a better radiator and pump.

But for best results, a separate loop would be ideal. Currently, my GT at 435/1200 is 47 C for core and 30 C for ambient.
