Does old heatsinks for R300/NV30 match R420/NV40?

[stoff]

Does anybody know whether the old heatsinks for the Radeon 9700/9800 line match the new X800 (holes, alignment etc)? The same goes for old heatsinks from the old 5900 on the 6800.

I’m asking because I need to start looking for a watercooling block for whatever card I get next (X800 or 6800).

I got an Innovatek setup now (Innovatek I-Cool rev. 3.0) for the Athlon XP and a InnovaGRAPH for the Radeon 9700 Pro. I going to keep the Innovatek setup so I need something compatible with their 8mm ID (3/8" OD) fittings/system.

PS: The new GDDR-3 RAM don't need cooling, so I’m just after a GPU-water block that already are in trade.

I'm curious too. I have a 9700 pro with a DD Maze4GPU. Maybe someone will know...

Thanks pauldenton...

Yeah, some research on the web suggest this to be the case. The 6800 GT/Ultra may also have the addition 'problem' that the power curcuit may need some cooling (as the fan sends the exhaust air on the power curcuit heatsink).

This all makes it a bit more complicated and expensive to go water-cooled on a 6800. At least at the moment.
