No temp monitoring, remember this was 1993 technology.

The SS20 has two heat "channels", one for the motherboard and processors
and one for the drives.  When I was running my SS20/812 in southern
California heat, I duct-taped on a couple of muffin fans to the starboard
side of the case blowing out, this was effective in increasing cooling
(dropped mbus module heatsink temp from 60C to 45C).  Doing something
similar to the HD area of the case might help as well.

Ditching the plastic side case baffles was good for another couple
degrees, though I covered them with wire mesh to keep various objects from
getting sucked in.
