I think it's important to note that this spacecraft will never reach these speeds because it's only designed to last a month or so, as can be read here:
The flight of Cosmos 1 will not last long. Within a month the mylar sails will begin to degrade in the harsh sunlight, and the tubes supporting the blades will be losing pressure. It is possible that by this time the spacecraft will have risen to a high enough orbit that it will remain there, forever orbiting the Earth. It is more likely, however, that the orbit will slowly decay, and Cosmos 1 will end its days as a fireball in the Earth's atmosphere.
Correct me if I'm wrong, but isn't heat capacity more important than heat conductivity in this case?
The article mentions a special kind of pump with no moving parts, so I assume the liquid is moving around from some sort of radiator to the GPU and back.
Water has the highest value of heat capacity if I'm not mistaken (4186J/KgK), so in case of a moving cooling liquid, the higher the liquid's heat capacity, the less water will have to be moved to move a specific amount of heat.

Unfortunately... performance and heat seem to move proportunately.
actually, the article's conclusion is that this is not the case.
what a completely useless review! the point is that you have to make the CPU 60% slower in order to make it 20% cooler.
why would anyone want to pay 400$ on a CPU then have it perform like a 50$ CPU just to win 2dB's of cooling sound?
no problem. there's always http://www.thepiratebay.org/

and http://www.bittorrent.com/ of course

What does heat conductivity matter, then?
finally, mobile pr0n !
gross...
