The sensor is located on the case (not near the exhaust) of the server. With the structure of my appartment this is the only place I can realistically put my Server but sadly also the hottest place in my appartment.
The outside temperature is supposed to reach 36°C today so I expect the ambient temp for the server to rise another 2-3 degrees.
I had a tower that generated so much heat that during a particularly hot summer, I had to stop using it around 1-2pm every day. The room just got too hot to occupy. I’m a computer nerd, so this was particularly heinous for me.
hottest day in what seemed like forever was here on Monday. Stayed away from studio/office as the heat was just unbearable! Im in the UK and it was around 32 outside and 35 in office as the 4-node heat generator was making a racket!
Computer says: “touch grass, or burn”
The computer fan with a 9V battery it is.
That and my trusty Jinbei house clothing
:sweat-smile: intensifies
0.7C increase isn’t anything to write home about?
Well that’s the ambient temperature graph I think. Wonder how the CPU temperature is affected. Is it also just a 0.7C increase or maybe more?
This is less about the increase during the last 24 hours and more about the current temp+expected increase.
My fileserver regularly ‘enjoys’ 45-50c during the day when I’m not home in summer.
Aircon isn’t cheap to run, so everythings getting fried while I’m at work (getting fried since we don’t have AC at work)
I’ll make you feel better: here’s a server of mine that lives in a hot garage. Sorry for the freedom units but it peaks at about 55C.
20F isn’t much of a fluctuation anyway.
Oh lordy, please tell me it’s at least not humid in there?
Nah, pump the humidity. Free sauna!
My server is in a closet without ventilation. You will probably be fine.
Not worrying temps for most stuff. If you have mechanical HDDs you may want to check those specifically.
My server rack is located in an uninsulated attic with two tiny windows. I haven’t measured the ambient temperature but I think it’s over 40°C. Yesterday one drive in my storage server reached 65°C - so for today I have shut it off until the rain comes. Fun times.
Ouch, I will defenelty check on the system temps once I get home. Although I can’t really shut the whole thing off, maybe I can at least spin down the drive pool and kill all containers relying on that.
The hardware in your server should be able to handle 50-60 degrees for a long period of time, so going to 35 ambiant shouldn’t be a problem.
Exactly! My drives are all sitting at about 40°C but they’ll get up to 50°C at the hottest.
I run a fan because I have it in a wall mounted case but when I had it on a shelf it wasn’t actively cooled and never got higher than it does now.
It is in our basement though and it’s only ever gotten to 27°C down there a few times and that was without A/C.
If that’s the flur just imagine how high the cerling is
Flur means hallway (it is at the ceiling)
My server has also not been liking the heat over the past month
Though in my case it’s because drive 3 is sitting in a slot that is possibly not getting enough airflow. It’s consistently running a bit hotter than the other drives in the system.
I really should get around to moving it to a different slot.
Been happening to me as well. And my basement is more cool than my 1st and 2nd floor.
no issues with temps here in the UK, but the fans don’t sound happy…
We’re doing fine here:
Aber Deutschland ist geschmolzen :(
How did you get your drive temps into home assistant?
*Deutschland wird schmelzen 🥲
Oh nee :((
It’s a Synology NAS so will work with the Synology DSM integration: https://www.home-assistant.io/integrations/synology_dsm
There’s definitely ways to poll the sensors of other devices though. I had some janky sensors set up before for monitoring a standard Linux box.
My Pi usually runs at ~ 40 Degrees Celsius. It doesn’t like this either.
My Pi spends all of its time around 55°C in a 20-25°C room. Main server idles at 47°C. Those aren’t worrying temps.
Yeah I know my desktop is idling around 60. Yet I’d rather have it a bit less warm on the passively cooled device ;)
My passiv cooled Pi5 (case as radiator) with HA is at 44°C (room is at 33°C). Idk how hot it gets on a regular basis, I just enabled the system monitor integration right now.
I mean with CPU temps, thermal throttling starts usually at 80°C, so nothing to worry.
My router (shit one provided by the carrier) is restarting frequently, I think due to overheating
Just yesterday I took measures to keep temp down further, powersave cpu governor, always full fan speed, 12 disks go to sleep after 60 min of inactivity and I removed dust for better ventilation. My NAS/server is in the attic and today theres 37°C outside
Disks were around 50°C which is too hot
12 disks go to sleep after 60 min of inactivity
That will kill your drives far sooner than a temperature spike. load/unload cycles is one of the biggest HDD killers.
I hobestly don’t know how much of this temperature is the server and how much is just it beeing in a badly ventilated spot under the ceiling.
I don’t really do disk spindown as they are active most of the time anyways (Zfs spends most of the time scrubbing).
For the rack in the closet, I cut a 4" duct off the ac, and piped it into the top of the closet. For one of my computers, it seemed to always run hot, so I bought two 6" box fans and mounted one over each of the two CPU. I have a little gadget that comes with Open Hardware Monitor so I can keep an eye on it. Currently running 100 freedom degrees, but it will fluctuate +/- 10 degrees depending on load. The only downside is they are a bit noisy, not extremely, but you can hear them buzzing away keeping shit cool so I don’t complain much and just turn the music up. LOL
