Nice idea, but if it works like Corsair's H50 then you need to have the fan to suck cool external air into the case over the radiator, and if you SLI the bugger then you have 2 or 3 120mm case slots used up, limiting your options for fans left to blow.
Case full of hot air anybody?
I was looking at using the Corsair H50 in a Silverstone Raven but ran into just this problem - with a case geared up to send air bottom-to-top, having the top 120mm fan sucking air back into the case will screw with the convection design big time, and I can see these BFGs doing the same.
Wonder how the life time warranty works with the pump?

I would expect it to be covered - it's all a single, sealed unit and therefore cannot be user serviced.
Whether reality reflects my expectations is yet to be seen.
