21C doesn't sound to bad for a server room to me.

and turning down the regulator too low is, as you say, asking for
trouble.

Once you have adequate aircon in a server room, more importance should
be attached to airflow. Most rackmount kit is designed to take air in
the front and exhaust it out the back.
Nothing worse, IMHO, than a small room crammed with kit which has
accumulated over the years.


I've done temperature sensing of cabinets, using Nagios and some
thermocouple probes. Worked well.
If you have a few hundred quid, its worth looking at the 'Jakarta'
sensor box, which can be bought from Scan.


I agree though that this problem could be dirty power.
For a server room, please God have a separate feed for the computers.
Don't share it with the air con, or domestic feeds. Just think of those
kettles and vacuum cleaners...
For the boxes out on your office floor, why not just get a Belkin type
surge protector strip from the local pc/office store? Or maybe a small
UPS.
