So I have my new TrueNAS build up and running. Quick question - how accurate is the CPU info on the dashboard. I have built my NAS from a SuperMicro Rack server and have moved it to an ATX case. To do this I had to buy and install a Senetic Active Cooler. I need to ensure the Cooler and Heatsink are working correctly, so how accurate is the CPU temperature readout on the TrueNAS dashboard?
A SSH session from another computer is most preferred, but failing that you may use the web shell, or an actual monitor to the console as a last resort.
So, yesterday I checked the CPU temp using the sensors command, both in the TrueNAS command line on a monitor connected to the NAS and from the TrueNAS Dashboard. I did not check the system BIOS.
It was very cold yesterday but these temps seem too low.
Was the system doing anything at the time of your reading?
I turned apps off for the photo, but will drop to below 15C on average just from the ambient air at idle
Obviously it massively depends on what the cooler is, and obviously different CPUs; but I wouldn’t worry about the temps you posted unless the air temp in the room is hotter, otherwise you have condensation risk, the server I posted is currently sitting in a very cold rack.
v’e added my NAS specs as my signature? But if not here’s a link to my build thread I started. NAS Build Thread
The Heatsink and Cooler is a genuine SuperMicro Active Cooler - I needed to buy this as the motherboard came from a 1U Rack and only had a passive cooler.
It’s a beast
I was copy files to the NAS from a USB HDD connected to a Macbook whilst reading the temps.
I think radio ham operators in the uk call the room where they have all their equipment their “shed”, so it must not necessarily be of the gardening variety (however the term might come from that originally).
Thanks for that. My numbers are coming from a small enclosure (IX Mini X+) with the cpu actively cooled. This also has one large fan (maybe 92mm) in the back to pull air over the 5 drives and cpu. I’ve outgrown this system and fixing to upgrade.
