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

By keeping your house at 25 degrees, you’re setting the baseline temperature of the house (i.e. it will never be colder than 25 degrees, period).
If you can get some airflow, why not just set your house to like 19 degrees, and use the fans of your unit to equalize the temperature in your unit (19 degrees is the new baseline, it will probably keep the unit a degree or two hotter just by the ambient heat generated by your server).
For what it’s worth a server is fine to run in this type of environment. What are the internal temperatures of your system? Is it overheating?
I don’t generate the heat in the first place. 35 celsius is comfy for servers, though.
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.
In the summer, I’m dumping it outside.
In the winter, I’m heating my garage with it.
Has worked great for many years now.
Ignoring it. My lab is in the garage. It gets hot here in the summer, but not incredibly hot. And if heat shortens the life of my hardware, it’s all cheap; I’ll just buy a cheap replacement.
Grow tents bro.
What are you running hardware wise? X5690 (aka something old, power hungry, hot, and not very efficient)?
I disagree that 30C is just peachy, but I suppose for home use it’s fine. But if your house is at 25C and room raise to 30C isn’t that much… depending on what you’re running and average utilization.
When I had a rack at home, it was a silent one (so almost completely sealed). I had a fat duct coming in from the outside into the bottom of the rack and another fat duct taking the hot air from the top outside. But in winter, I made sure it was blowing that hot air into the living space.
What’s the power output of all your hardware?
I don’t really have any input on your question, but I have one of my own.
25°?? Is that a typical indoor temperature for houses in Norway? I’m in Canada and my house sits around 19° most of the year, as do most people I know.
I had the exact same thought… our heat is set to 20 most of the time. 25 would be hot!
Maybe energy is cheap there or OP is rich, I live in the UK and was surprised by the temperatures they quoted.
I would say though that Scandinavian houses are known for being very well insulated and energy efficient.
My heating is on 19C when I’m home, lowered to 10 while I’m out/sleeping because my cat has his own fur coat to keep him warm and I have a 13 tog duvet
I hope you have very low humidity, going that low can create a risk for mold forming in your walls.
Lived here 8 years and no mould issues so far.
I’m about 21-22 year round (also in Canada) and my server room isn’t much warmer than the rest of the house but it isn’t closed off either. The larger air space you can give it, the better.
Also Canada and I keep mine closer to 24-25c. 19-20 waa what my parents used to do growing up lol.
Yup, mine is around 18-19 in Canada, 25 is wayyyy too hot
You’ll need inlet and outlet, not just outlet. Also, look at your server power usage too, drive don’t generate newrly a much heat.
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.
As a fellow Norwegian ive always just vented the air into the living area (with a sound trap after fan).
A few places ive lived this has been all my heating all year.
I live in Australia.
I pump all the heat out of my server room to the outdoors.
In doing this I am assisting cooling the planet by pumping my low temperature servers heat into the environment and reducing the overall global temperature increase.
You’ll have to provide cool air to the room as well. No amount of extraction will help if you don’t do that.
