Hmm... I use PF-5080 on a dual Opteron 250 and Radeon 9800Pro, the whole lot cooled by a single BIX with a quiet Panaflo low-flow fan; coolant flow is 1.73 litres/min. Temps are in the 42C to 47C max. range in a room at 20C. Not as good as water, perhaps, but I'd say Fluorinert does OK.
Agree with BillA though: more money than sense. It is so easy to build an elegantly simple, quiet system without having to resort to complex cooling solutions and sound-proofed walls and all that jazz.
