You'd also have to do it in a climate controlled area to make sure ambient temperature was constant, an air-conditioned office would do. I wouldn't be a bit surprised to see huge losses thru a faulty seal, it's alarming to see how much coolth you can lose in a tiny gap. After extensive whining ('too hot!' 'too cold!') at an old job, I placed a number of temperature dataloggers around the office, including one in the server room with it's own air-conditioners. FWIW, the server room area was originally where a mainframe was, so we already had a raised floor. Nice. We only needed 1/3 of the area, so that bit was walled off, the remainder was left empty and christened the dance floor*, complete with railing, disco ball and blinkenlights from the server room hardware. Anyway, we left the old labelled fuse box, the idea that a printer would need 40 amps and a hard drive some ungodly number was fascinating to those of us who started on Apple IIs and the like. The server door had keypad entry, and this was a PITA. We were a small company then, so we used to wedge it open by dropping a tile lifter (those vacuum things) in it. This only cracked the door open a few millimetres (say 1/8th to less enlightened folk), but had the effect of making the server room temperature the same as the general office. Hmmm. As a bonus, you could see when the first person came in, and when the last person left by noting the sudden temperature change as the door was initally opened and then eventually closed properly. So that's why our air-conditioners kept blowing up. Oops. We later realised we could brew beer in there, and lowered the temperature. This was stopped not because we realised it was a bad-ish idea, but one guy pointed out he was tired of turning blue after spending long periods in there. Tony * We eventually lost the dance floor when the number of staff went up, at that point keeping the server door locked became a really good idea too. Yes, we did use it for parties. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
