Danger Den Water Block for 8800GTS/SSC
This block has the polycarbonate top.
The first thing I had planned for this block was to take it to work and pressure test with air at 20 PSIG while submerged under water. We set up a test fixture with a regulator and proceeded.
Unfortunately I had a leak between the poly and the block at the radius shown.
I called Danger Den (DD) and they told me that was the hardest place to stop from leaking. They have just recently changed the screws from Hex Head to Pan Head so they could tighten them more. I could either send it back or replace the screws. I opted to replace the screws. In order to get them out I had to use a Dremel to make a slot in the head then use a flat tip screw driver to remove them. All screws were #4-40 size with various lengths. Leak tested again with new screws and I was good to go. I highly recommend everyone to test their blocks outside the computer case for leaks because it can save you a major headache!
Remove the screws with springs in them and the one's around the GPU to remove the stock cooler. Once they were all loose just give a slight twisting to break the bond to the GPU.
------------------------------------------------------ Here it all cleaned up with thermal pads and thermal grease applied. I used their goop for the memory and AS5 for the GPU. I prefer spreading the stuff rather than placing a dab and let it mush out.
Testing for leaks.
Block installed.

The hardware used can be found here.
Hear are the results using RTHDRIBL and the stock cooler.
With Water block.
All testing was done with my Nautilus 500 water cooler and the fan on low speed. I did notice that playing Rainbow 6:Vegas at 1289 x 960 that the core ran on average at 49 C versus 63 C on air with the cards fan running 100%.
