As long as you stay on the dark side of the moon you don't have to use any form of cooling, not even a heatsink biggrin.gif

how would you dissipate the heat generated by your rig? It won't radiate fast enough to cool anything.

At around -150C I don't think you really would need a heatsink.

How long would that even take?
the Logistics behind it are mind boggling

The last mission to actually go to Jupiter and stay there (Galileo) took 6 years to get there.
By contrast, New Horizons (mission to Pluto) was launched in Jan 2006 and flew by Jupiter in February 2007, but it wasn't designed to stop at Jupiter.
So it is possible to get there much faster than Galileo did, but you have to plan for deceleration so that you stay within the Jovian system.

Science time! Temperature is not directly related to heat. In the near vacuum of space, what few particles there are are very cold. However, because they're so few and far between, radiation is the only viable cooling method. Compared to convection or conduction, though, radiation is very inefficient. Even on the moon, a computer would not be able to get rid of heat fast enough. So, just because something is cold doesn't mean it can conduct heat very well.

Edit: Keep in mind that a thermos works on this principle. the air between the outer part and inner part is vacuumed out, greatly reducing heat transfer from the contents to the environment and vice versa.

And that is why spacecraft CPUs are, by desktop computer standards, ancient pieces of junk. I was just talking about the Galileo probe. It used an RCA 1802, which was already 13 years old when Galileo was launched. The International Space Station's central command computer uses an Intel 80386 SX 20 MHz with a 80387 FPU. My first computer 20 years ago had a 386 SX 16 MHz.

Indeed. For comparative purposes, this is one of the 6 radiators on the ISS (there might be more now, since they've added things to it)-

Well...not exactly the only reason. CPU's used in space need to be radiation hardened and whatnot.
