Anyone tried Zalman ramsinks with z 7800gt?

[MoJo-chan]

I'm now just waiting for the hold-down bracket to install a Maze4 on a 7800gt, but of course the Maze4 only cools the GPU and not the ram.

I have some Zalman ZM-RHSI heatsinks for the RAM, but will they be enough? I can't find any info at all on these being compatible or not with the 7800. I could probably wedge a 5V Papst in there but I was hoping to get away with the minimal air flow from the fan at the front of my case.

I could fork out for a new block to cover the ram, but for £65 and the hassle of draining my system again...
