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.

[-] irmadlad@lemmy.world 1 points 7 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

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

[-] boonhet@sopuli.xyz 10 points 15 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 14 hours ago* (last edited 14 hours ago)

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

[-] errer@lemmy.world 12 points 10 hours ago

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 1 hour ago

20F isn't much of a fluctuation anyway.

[-] KairuByte@lemmy.dbzer0.com 1 points 7 hours ago

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

[-] Railcar8095@lemmy.world 1 points 6 hours ago

Nah, pump the humidity. Free sauna!

[-] 3dcadmin@lemmy.relayeasy.com 2 points 9 hours ago

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

[-] bricklove@midwest.social 4 points 10 hours ago

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

[-] needanke@feddit.org 2 points 3 hours ago

Flur means hallway (it is at the ceiling)

[-] qaz@lemmy.world 9 points 12 hours ago

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

[-] doeknius_gloek@discuss.tchncs.de 9 points 14 hours ago

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 2 points 14 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.

[-] capuccino@lemmy.world 1 points 9 hours ago

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 2 hours ago

A little bit late, but here it is.

[-] needanke@feddit.org 1 points 3 hours ago

How is the cpu below ambient temperature?

[-] capuccino@lemmy.world 1 points 2 hours ago

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

[-] Humanius@lemmy.world 6 points 15 hours ago

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 13 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 15 hours ago

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 1 hour 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.

[-] sfxrlz@lemmy.dbzer0.com 3 points 14 hours ago

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

[-] tburkhol@lemmy.world 6 points 14 hours ago

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 13 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 11 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 13 hours ago

Guess it might be benefitting from fans though 😄

[-] synapse1278@lemmy.world 3 points 15 hours ago

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

[-] SigHunter@lemmy.kde.social 3 points 15 hours ago* (last edited 15 hours ago)

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 14 hours ago* (last edited 14 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 14 hours ago

We're doing fine here:

Aber Deutschland ist geschmolzen :(

[-] needanke@feddit.org 2 points 14 hours ago* (last edited 14 hours ago)

How did you get your drive temps into home assistant?

*Deutschland wird schmelzen 🥲

[-] swizzlestick@lemmy.zip 1 points 13 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.
