However as mercury is so heavy it will take one hell of a pump or much tuning and work on an electromagnetic pump to achieve that rate.

The think to look into would be a personalized ferrofluid or just a mercury based solution(and heterogeneity becomes a challenge here) or alloy with: high heat conductivity, high thermal capacity, low viscosity(to allow high flowrate) and possibly incorporating iron,cobalt or nickel to be used with an eleectromagnectic pump for better flow.

Basicly good luck finding the combination of budget and skills required to create a fluid like this and building the loop to run it. I know I havent got anything close to those skills

It would be very hard to do something like this let alone expensive but I would love to see someone pull it off.

Ok. I feel like a few people have the interest in it, so I'm thinking lets add to an existing thread, ill beposting the data I could gather on some fluids, and the ideas I have to run this type of loop, hope people will contribute: http://www.overclock.net/t/753637/liquid-cooling-with-mercury
