8800 gt cooling.

Real quick question the build in my sig is my first one. I'm thinking about putting in a vga cooler for the gfx cards. What would you guys recommend? I'm running them in SLI, they are not overly hot, but I pretty much just wanna see if i can throwing one in there.
thanks in advance

A lot of the after market coolers are pretty big, how much room do you have in between your GTs?

aah i wanna say less than 2 inches. I'll have to check it when I get home.
