I've very little experience with computers in racks, but if the machines are
actually touching, then yes, this could be the case.

The 65 C temperature a previous poster was talking about is not the maximum
operating temperature for the actual processor, it's the maximum temperature
in the case while the computer is operating. As far as I know CPU
temperatures are measured on the actual processor die, and the case
temperature will normally be *much* lower.
