My earlier post probably did overestimate the negative effect such a socket extender would have on a system, but the fact remains that any modification of the signal traces' length will change the signal handling properties of the system, possibly out of the range it was designed to handle.
Any modification of trace length
will affect the system's maximum overclock.
At these frequencies, resistance is the least of the issues signal engineers have to deal with - Dan's data responded to a letter a while ago which brought up some of these issues:

Trace length isn't the only factor. There are capacitance and resonance and resultant signal settle time issues as well; when you're dealing with high speed digital systems you end up fiddling with a lot of analogue variables.

Realistically, these issues would counteract any possible benefit backside cooling would offer. Socket extensions are simply not viable if you're seriously concerned about an overclock.
I'd still like to see backside cooling put to use though. Best of luck, bigben, if you're going to try implementing it.
