My server currently runs in the loft
I am curious!

I would have thought that running any sort of equipment in the loft is
asking for trouble. Reason being that the temperature up there can go
outside the specs of the equipment. It gets damned cold up there in
winter and sweating hot in the summer.

If you don't take any steps to control the temperature then it could be.

Methinks you worry too much.

Any decent kit (i.e something that's not been cobbled up in a 3rd
party case) has a wide operating temperature, and it is the rate of
change of the ambient temperature that causes an issue, not the
actual maximum or minimum temperatures.

My firewall (Compaq Pentium 2) is in the loft with no special
insulation around it, and the projected low for tonight is -4.

I'm not worried about it. It will just get extra cooling this evening
;-)

I have had computer room air conditioning failures causing a very
steep step change in temperature (up to ~32 degrees C in 1 case) I had
3 disk failures out of an installed base of ~600 and 1 machine auto
shut down due to overtemperature out of 200 (and this was found to be
too close to adjacent kit).

Similarly I have seen machines operate at either end of their
envelopes [1] without incident.

Cheers,

Paul.
