What are you doing with heat? (alien.top)

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

Heavy computation rack is in an unheated conservatory with a window cracked open. Keeps the HDD temperatures around 30 degrees. Temperature monitoring from my PDU shows a 3'C rise from the inlet to the exhaust side of the rack. This stuff is mostly powered off when not in use. In summer, it can get to 35'C in that room so I shut everything down at that point.

24/7 rack is in my lounge and vents the heat into the room (helps a little bit with heating costs). Top of the rack is about 37'C but I've seen it around 45'C with all my hypervisors doing stuff. Nothing complains. As long as the intake air is within the manufacturer's stated range, it's fine.

Might want to consider redirecting the heat into the house rather than venting it outside.
