I am starting to wonder why my server system is making SO much heat. I live in Norway, so outside temperature is around freezing, and my house I keep it around 25 degrees inside, except no heating in the server room. It got a roof extraction vent that is constantly sucking out air in that room, and I just had it inspected to be working perfectly fine.
Still its always over 30 degrees in that room, and the hot air is oozing from the server. Its just a consumer based drive and a couple of switches, plus a UPS, and its so warm in there.
Im getting afraid the high temperature can affect the hardware when its 30-35 degrees inside the server rack
I vent to the attic using a duct fan.
Hard drives produce a lot of heat. Switches can produce a lot of heat, particularly older switches (and routers).
But, yes, temperature is your enemy.
