Yes, especially on the older 65nm chips. I ran over 2v into a q6700 on dry ice with -70c and it runs the same as day one 45nm is harmed quicker by more voltage but the same principle works for them as well.

Low temps slow current migration to a point but not completely.
Chips overclock higher at the same voltage as temperature decreases and yes you can also increase your voltage without worrying too much about chip damage as long as the run is not to long.

Example: I have a QX9650 which I have been running happily at 4.7ghz and vCore = 1.55 for almost a year now under a SS but have also benched this under a triple cascade using close to 1.9volts...

If I hadn't been running the chip at very low temps then the chip would be a paperweight now...

Silicon or some sort of epoxy.

To stop condensation from doing any damage to the surrounded area I believe.

Kneaded Eraser...? That you have 158rep, TOAD, makes me believe that answer... but, wouldn't the condensation just run off it onto the unprotected area around it?

I was thinking about this last night too, what if you built a case that suspended your MoBo from the top, that way all moisture and condensation would have zero access to the board?
