X1600Pro 256 with AquaXtreme MP-1 GPU WB
 

This is a continuation of my previous thread here: http://forums.procooling.com/vbb/showthread.php?t=12931

Time to quit talking water cooling and actually doing it eh?
First have to install the 2 all threads into the right holes for the card

Then install the 2 little black risers and then the brace, springs and nuts.

Block installed on card and card in comp.:

I used the AquaXtreme 50Z pump I got from Cooltechnica and a chevett heatercore I got from greenman of these forums.

I used ATI Tool .25 beta to read temps and overclock.

Temps dropped over 30C both idle and load with this block. Another positive is the temp difference between load and idle is significantly less. Idle it runs 33C and load is 38C.

I also noticed when I took the stick air cooler off the card it was very hot. I pretty much believe this is actually making the memory warmer than cooler on the 4 of 8 meme chips it touches. IMO the size of the cooler is not to help cool ram but just there to spread the heat over a larger area.

The main down side is the overclocking gain was pretty much insignificant. Stock I could go to 605mhz and with this setup I can only get to 635mhz. However this is not all bad for the people who prefer quiet. This gives you a LARGE amount of room to work with. You have 30C to make the thing quiet.

I am also impressed with the little 50Z pump. It has plenty of power and is as quiet as a slow 80mm case fan (as of now anyway).

I've been seeing many reports of much lower temps on video cards lately, when converting to water cooling. Sadly, overclocks aren't improving as much as they used to.

Good work, but I cringe when I see big metal objects (i.e. the back bracket) so close to uninsulated SMT components; a video card is so easily damaged.

I see that you removed the pads on the memory chips; looks like everything was built flush with the top of the GPU core. Do those ramchips run hot at all?

It is not nearly as bad as it looks on that bracket. There are 2 black risers that lift the bracket off the PCB about 1/8". It is clearing everyting.

The pads were not attached to the ram, they were attached to the stock heat sink. I think it was just more of a leveling thing than anything along with the white square.

Also I guess I can put in a pic of the base of the block. Machine work is excellent.

Forgot to add: Hardly get warm at all.

I've encountered the same thing with ATI gto^2. Great overclockers and on air. Core 400mhz>520mhz and 1ghz on ram > 1.2ghz. On water get about 30mhz on the core. Ram doesn't get any better with heatsinks.

It seems heat is not as a much of a factor in current parts. Once you hit the wall with air cooling, it seems like you really hit a wall and water doesn't offer much improvement in performances.
