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.
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
My server is in a closet without ventilation. You will probably be fine.
My Pi usually runs at ~ 40 Degrees Celsius. It doesn’t like this either.
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 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.
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.
This is the temperature right now (8:50am local time), I will comment again at 3:00pm xd Normally the ambient temperature here is over 40°C.
How is the cpu below ambient temperature?
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.
Not worrying temps for most stuff. If you have mechanical HDDs you may want to check those specifically.
30.8 to 31.5……that’s nothing at all. What am I missing here?
31.5°C also is just a bit slower at cooling, and computer devices easily reach 95°C without any troubles.
Hard drives don’t really like high temperatures for extended periods of time. Google did some research on this way back when. Failure rates start going up at an average temperature of 35 °C and become significantly higher if the HDD is operated beyond 40°C for much of its life. That’s HDD temperature, not ambient.
The same applies to low temperatures. The ideal temperature range seems to be between 20 °C and 35 °C.
Mind you, we’re talking “going from a 5% AFR to a 15% AFR for drives that saw constant heavy use in a datacenter for three years”. Your regular home server with a modest I/O load is probably going to see much less in terms of HDD wear. Still, heat amplifies that wear.
I’m not too concerned myself despite the fact that my server’s HDD temps are all somewhere between 41 and 44. At 30 °C ambient there’s not much better I can do and the HDDs spend most of their time idling anyway.

On the contrary, they found that temperature had almost no bearing on failure rate.
Yeah this temperature is nothing. Regularly gets over 40 degrees Celsius where I am, and all of my home servers have run 24/7 through it without issue, not in air conditioning.
no issues with temps here in the UK, but the fans don’t sound happy…
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.
We’re doing fine here:
Aber Deutschland ist geschmolzen :(
How did you get your drive temps into home assistant?
*Deutschland wird schmelzen 🥲
If you feel particularly nerdy and love stats and graphs, here’s a rabbit hole for you
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”
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.
Oh lordy, please tell me it’s at least not humid in there?
Guess it might be benefitting from fans though 😄
If that’s the flur just imagine how high the cerling is
Flur means hallway (it is at the ceiling)
