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.

Not worrying temps for most stuff. If you have mechanical HDDs you may want to check those specifically.

0.7C increase isn't anything to write home about?

[–] boonhet@sopuli.xyz 12 points 20 hours ago

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?

[–] needanke@feddit.org 5 points 19 hours ago* (last edited 19 hours ago) (1 children)

This is less about the increase during the last 24 hours and more about the current temp+expected increase.

[–] errer@lemmy.world 10 points 15 hours ago (2 children)

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.

[–] ikidd@lemmy.world 1 points 6 hours ago

20F isn't much of a fluctuation anyway.

[–] KairuByte@lemmy.dbzer0.com 1 points 12 hours ago (1 children)

Oh lordy, please tell me it’s at least not humid in there?

[–] Railcar8095@lemmy.world 1 points 11 hours ago

Nah, pump the humidity. Free sauna!

[–] FreedomAdvocate@lemmy.net.au 33 points 20 hours ago (1 children)

30.8 to 31.5……that’s nothing at all. What am I missing here?

[–] Honytawk@feddit.nl 8 points 19 hours ago (2 children)

31.5°C also is just a bit slower at cooling, and computer devices easily reach 95°C without any troubles.

[–] FreedomAdvocate@lemmy.net.au 5 points 19 hours ago

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.

[–] Jesus_666@lemmy.world 1 points 15 hours ago

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.

My server is in a closet without ventilation. You will probably be fine.

[–] bricklove@midwest.social 4 points 15 hours ago (1 children)

If that's the flur just imagine how high the cerling is

[–] needanke@feddit.org 2 points 8 hours ago

Flur means hallway (it is at the ceiling)

[–] irmadlad@lemmy.world 1 points 11 hours ago

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

[–] doeknius_gloek@discuss.tchncs.de 9 points 19 hours ago (1 children)

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.

[–] needanke@feddit.org 3 points 19 hours ago

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.

[–] 3dcadmin@lemmy.relayeasy.com 2 points 13 hours ago

no issues with temps here in the UK, but the fans don't sound happy....

[–] Humanius@lemmy.world 6 points 20 hours ago (1 children)

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.

[–] j0ester@lemmy.world 1 points 17 hours ago

Been happening to me as well. And my basement is more cool than my 1st and 2nd floor.

[–] Strit@lemmy.linuxuserspace.show 6 points 20 hours ago (1 children)

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.

[–] LilB0kChoy@midwest.social 1 points 6 hours ago

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.

[–] capuccino@lemmy.world 1 points 14 hours ago (2 children)

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.

[–] capuccino@lemmy.world 1 points 7 hours ago

A little bit late, but here it is.

[–] needanke@feddit.org 1 points 8 hours ago (1 children)

How is the cpu below ambient temperature?

[–] capuccino@lemmy.world 1 points 7 hours ago

Had the AC on in my room. It's off since morning.

[–] synapse1278@lemmy.world 4 points 20 hours ago

My router (shit one provided by the carrier) is restarting frequently, I think due to overheating

[–] sfxrlz@lemmy.dbzer0.com 3 points 19 hours ago (2 children)

My Pi usually runs at ~ 40 Degrees Celsius. It doesn’t like this either.

[–] tburkhol@lemmy.world 6 points 18 hours ago (1 children)

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.

[–] sfxrlz@lemmy.dbzer0.com 1 points 18 hours ago

Yeah I know my desktop is idling around 60. Yet I’d rather have it a bit less warm on the passively cooled device ;)

[–] ZeldaFreak@lemmy.world 2 points 16 hours ago

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.

[–] bright_side_@lemmy.world 2 points 18 hours ago

Guess it might be benefitting from fans though 😄

[–] SigHunter@lemmy.kde.social 3 points 20 hours ago* (last edited 20 hours ago) (1 children)

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

[–] needanke@feddit.org 1 points 19 hours ago* (last edited 19 hours ago)

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).

[–] swizzlestick@lemmy.zip 2 points 19 hours ago (1 children)

We're doing fine here:

Aber Deutschland ist geschmolzen :(

[–] needanke@feddit.org 2 points 19 hours ago* (last edited 19 hours ago) (1 children)

How did you get your drive temps into home assistant?

*Deutschland wird schmelzen 🥲

[–] swizzlestick@lemmy.zip 1 points 18 hours ago

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.
