Really? what specific GPU's and CPU's are you cooling? I've been told that a 120x2 + 200x1 should be enough to cool an i7 950 and a GTX 570, so I'd imagine an extra 120x1 would be fine for my purposes.... right?
I have three GTX580's wet and a i7 2600K @ 4.5Ghz. It's just acceptable for the GPU's, but my CPU goes over the 75c (which I don't like at all) while folding. When I was running 2 GPU's and the CPU I was hitting no higher than 70 on the CPU and 40's for the GPU's.
Hence why I said "can only". I now have to look for a better case, more rads and sell my 650D with rads and pumps.
Hey, you wanna buy it? =P
