Actually ....

I had an overheating problem once with an Axil S.320 with four 125MHz
Ross HyperSparcs.  The solution we eventually took, as advised by a
friend of mine who happened to be an Axil FE, was to simply swap out the
S.320 power supply for an S.420 power supply, which had a bit more
cooling capacity.

Before becoming aware that this option existed, though, I seriously
considered attaching a Peltier cooler (or several) and appropriate
heatsink(s) to the outside of the case directly above the CPUs.  I
figured with the entire case top nice and cold, I ought to be able to
suck a fair bit of heat out of the machine that way, since the top cover
normally became quite hot to the touch after an hour or two of
operation.  (It still got pretty warm after installing the uprated power
supply.)
