Cooling 2 5850's!

Hey,

Ok so currently I've got a loop in my 800D with a 360 rad at the top in push/pull config, and that takes the heat off my i7 950 @ 4.2ghz & my first 5850.
I got the second 5850 a few days ago, and would LOVE to add it into the loop, purely for the looks, but I can see it being a problem cooling wise!
From what I can see, i'd definitely need to add another radiator into the mix, but I'm wondering what size I can get away with? I don't really want to modify my case so putting a 360 or anything in the bottom is out of the question!

I know I can get a 140 ( or 120?) in the bottom, but do you know of any other leeway I have with cooling this second card? And also more importantly, If i was to add a 140 radiator, would it be enough to keep the extra 5850 cool?

I also have the problem of finding another 5850 block, but I'm sure I can find one :)

Cheers
 
Idle is around 45C for the cpu and 35-40C for the gpu, CPU isn't the coolest i guess (want to get Sandybridge/Ivybridge).

Under load after about 3 hours the CPU can get up to 70 (never seen it go over and only seen it touch the mark, not gone over), but GPU stays at about 40-60C, so temps are pretty fine tbh.

I'll just get another 140 and see how it is :D
