Cooling Maze4 vs 7900gs compatibility

Hi guys I was wondering if you could help me out?

Atm im using a 6800GT with the maze4 water block, i've decided to upgrade since its starting to show its age a lil bit, so I was looking at the 7900gs on scan, good price! However I cant seem to find out if my block is compatible, I tried looking on the DD site but the fastest card it says it supports is the 7800gs. So does anyone have a 7900gs with an M4 or know if they are compatible?

 

They work. You can even make it support GF8, though they want you to get a Maze5 now...
