Hi,
it is written everywhere that S1 N97 is compatible with Linux and due to the double Ethernet card also with pfsense.
I need to install Proxmox to also virtualize pfsense but the seller told me that the fan speed would not be managed according to the load/temperature of the CPU if I install Linux.
It is true?
If so, it is not true that it is compatible with Linux

Bonjour
Proxmox installé depuis quelques jours avec 2 VM dont une avec plusieurs containers Docker et je n'ai pas de problèmes de température, bon il fait froid en ce moment

ok, thanks for the reply, I hope I don't have any problems

Were you able to read the fan speed? With Fancoltrol LMsensors I can't read it, the temperature never drops below 50° even with very low workloads. I have the impression that the fan always has the same speed and does not change it with the temperature. Did you succeed?

Sei riuscito a leggere la velocità della ventola? Con Fancoltrol LMsensors non riesco a leggerlo, la temperatura non scende mai sotto i 50° anche con carichi di lavoro molto bassi. Ho l'impressione che la ventola abbia sempre la stessa velocità e non la cambi con la temperatura. Ci sei riuscito?

Code: Select all

nvme-pci-0100
Adapter: PCI adapter
Composite:    +52.9°C  (low  = -273.1°C, high = +82.8°C)
                       (crit = +84.8°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +44.0°C  (high = +105.0°C, crit = +105.0°C)
Core 0:        +44.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:        +44.0°C  (high = +105.0°C, crit = +105.0°C)
Core 2:        +44.0°C  (high = +105.0°C, crit = +105.0°C)
Core 3:        +44.0°C  (high = +105.0°C, crit = +105.0°C)

It would be nice if someone more knowledgeable could provide an answer. Thank you

I run the latest ubuntu desktop on my S1, and I can confirm that the fan does speed up under heavy loads. you can test it by overloading the cpu with:
open multiple ssh session into your s1 and run the above to stress test the cpu.

Many tks Bob for reply, I will try.
It's strange that the temperature never drops below 48/49 °C.
Other mini PCs I have also reach 40°C with low load

non /dev/zero a peu d'interet pour un stress de CPU, vous devez utiliser /dev/random

dd if=/dev/random of=/dev/null bs=1M &

et vous le lancez 4 fois (4 cpu).

Sous FreeBSD l'ACPI a un problème pour le retour des températures, mais le module kernel coretemp fonctionne très bien.

root@minipc:~ # kldload coretemp
root@minipc:~ # sysctl -a | grep temperature
dev.cpu.3.temperature: 47.0C
dev.cpu.2.temperature: 47.0C
dev.cpu.1.temperature: 47.0C
dev.cpu.0.temperature: 45.0C

avec les 4 dd de /dev/random vous montez rapidement à environ 60.0C et l'on entend bien le ventilateur qui change de rythme.

root@minipc:/ # sysctl -a | grep temperature
dev.cpu.3.temperature: 62.0C
dev.cpu.2.temperature: 61.0C
dev.cpu.1.temperature: 59.0C
dev.cpu.0.temperature: 59.0C

Donc je sais pas d'ou vous tenez le fait que le ventilateur ne change pas de vitesse avec Linux mais c'est faux. (J'ai testé sous Debian et pas qu'avec FreeBSD sur un un ACEMAGIC S1 N97).
