- I started to flame here. Then noticed where this was from. I
- don't live in a climate the requires air conditioning...
- In Canada and the US most homes and businesses are overheated.
- One study I read said 65 F for jobs requiring manual dexterity. 60 F
- for brain work. 50-55 for physical labour, and < 50 for sleeping.

- We try to keep our machine room at 18 C, Workstation rooms at
- 20 C.
- Colder is better to a point. Watch the humidity. Don't want
- condensation on the circuit boards. Most lcd's start having trouble at
- -20 C or so, and some electrical components stop at -40.
-
- More important than the temperature though is the change in
- temperature. Whatever temp you have, keep it the same.
-
- For hard drives the MTBF drops by 50% for each 10 C up in
- temperature. Can't say if the reverse is true.
