Freon for temps and speed fans but I dont understand it all

idontknowlinux · 03-17-2021, 06:25 PM

Hello people!
SO I installed Freon so I could see the temps in my gpu, cpu and speed fans, however being a noob I dont understand everything.

First: the fans speed (I have 4) are not being shown.

Second: I have 8 temps. After studying I understood Tccd1, Tctl, Tdie and Temp1. But I cant understand the first 4 ones Composite (2x) and Sensor 1/ Sensor 2. Any help?

Third: Any way of logging them while I play so I can see that everything is runnning smootlhy?

And fourth: Is there any way of controlling the speed of the fans?

Distro: Pop!_OS 20.10
Motherboard: Asus 570-X Pro Wifi (I am having issues with the wifi bit but thats another post)
Ryzen 5 3600

Thanks

It depends on the sensor chips your motherboard is using, not all of them are supported/fully supported, therefore you might not get some information. I have an ASUS board too, and it doesn't show the CPU fan speeds, or any other fan speeds either in Linux - I'd have to go into the UEFI firmware settings to see that info.

The Composite (2x), Sensor 1, and Sensor 2 temps might be for your NVME card - they are on my system (I've posted some of the output from sensors on my system below for you). You can run the sensors command to see more detailed info about where the temps you're seeing are coming from.

I suppose you could write a script to do that, if there isn't some log you could look at (can't think of any logs off hand though).

The only way I know of to control fan speeds, and only CPU fan speeds at that, would be UEFI/BIOS settings. But you probably wouldn't be able to set an exact speed as such though, you'd probably only be able to set it to something like "always run at full speed" or "dynamically adjust speed based on temperatures", or similar.

Code:

nvme-pci-0400
Adapter: PCI adapter
Composite:    +38.9°C  (low  = -273.1°C, high = +84.8°C)
                       (crit = +84.8°C)
Sensor 1:     +38.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +34.9°C  (low  = -273.1°C, high = +65261.8°C)

You could run sensors-detect and see if there are any existing drivers not loaded automatically.

You can log the fan speeds and temps that are reported by sensors with a script that selects what you want to record from the output and stores it. I have been using gkrellm to monitor my system, which also has means to monitor a lot of different things beyond temps and fan speeds. The extras include cpu activity, network and disk activity,memory usage, and more.

I just installed freon to test it out, and I am quite disappointed in the configuration options. The 2 temps it displays on the top bar, by default, are average temps and max temp.
The average is the average from all reported inputs, and is FAR from accurate. On my system I have about 15 temp sensors, 5 on HDDs alone, and 7 that are reporting values from -62C to 0C to some other invalid value. The average is all of those and does not reflect only the valid values. I can find no way to select which values are included in the average so the average is useless. The only 2 that are actually valuable are cpu and gpu temps, along with the system (mobo or case) temp.

My system has (in the bios) 4 different fan speed profiles ranging from quiet to full speed constantly. The profiles are temp controlled and you select the one that best fits your usage and allowed noise levels for acceptable temp control.

Since my daily driver runs at between 30% and 80% cpu full time I chose the performance profile and with cpu at ~60C the cpu fans are at about 3/4 speed.

Sensor 2:     +34.9°C  (low  = -273.1°C, high = +65261.8°C)

Code:

You are right! It is from my SSDs. 

nvme-pci-0100
Adapter: PCI adapter
Composite:    +34.9°C  (low  =  -5.2°C, high = +83.8°C)
                       (crit = +87.8°C)

iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +27.0°C  

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +33.0°C  
Tdie:         +33.0°C  
Tccd1:        +32.5°C  

nvme-pci-0400
Adapter: PCI adapter
Composite:    +33.9°C  (low  = -273.1°C, high = +80.8°C)
                       (crit = +81.8°C)
Sensor 1:     +33.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +42.9°C  (low  = -273.1°C, high = +65261.8°C)

Regarding the fan speed I will look at bios, thanks!

I did! https://www.linuxquestions.org/quest...es-4175692211/

But upon installing nothing different happened.

Just took a look at it! Looks good, at least better than freon!
