From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hi everyone,
I just just installed coolercontrol recently to control my gpu fan curve then i realized there is this nct6687 sensors which report some extremely high temp sometime even 100 Celsius. I tried the sensors.
Which show that nct6687 still have really high temps. Is this normal? Or is my pc burning it self even though the air in the pc isnt hot at all.
Note: I use arch. My mobo is MSI B450M-A PRO MAX II. My gpu rx 580. My CPU r5 5500
First of all you need to figure out which sensor this even is. On my nct6687, there's a sensor on the PCIe slot that is constantly >90° and that appears to be totally normal.
Could you post the output of sensors?
Here is how it looks like on my machine:
nct6687-isa-0a20
Adapter: ISA adapter
+12V: 12.26 V (min = +12.14 V, max = +12.46 V)
+5V: 5.06 V (min = +5.00 V, max = +5.08 V)
+3.3V: 0.00 V (min = +0.00 V, max = +3.40 V)
CPU Soc: 1.02 V (min = +1.02 V, max = +1.04 V)
CPU Vcore: 1.27 V (min = +0.91 V, max = +1.40 V)
CPU 1P8: 0.00 V (min = +0.00 V, max = +0.00 V)
CPU VDDP: 0.00 V (min = +0.00 V, max = +0.00 V)
DRAM: 1.11 V (min = +1.10 V, max = +1.11 V)
Chipset: 202.00 mV (min = +0.18 V, max = +0.36 V)
CPU SA: 1.08 V (min = +0.61 V, max = +1.14 V)
Voltage #2: 1.55 V (min = +1.53 V, max = +1.57 V)
AVCC3: 3.39 V (min = +3.32 V, max = +3.40 V)
AVSB: 0.00 V (min = +0.00 V, max = +3.40 V)
VBat: 0.00 V (min = +0.00 V, max = +2.04 V)
CPU Fan: 730 RPM (min = 718 RPM, max = 1488 RPM)
Pump Fan: 0 RPM (min = 0 RPM, max = 0 RPM)
System Fan #1: 0 RPM (min = 0 RPM, max = 0 RPM)
System Fan #2: 490 RPM (min = 421 RPM, max = 913 RPM)
System Fan #3: 0 RPM (min = 0 RPM, max = 0 RPM)
System Fan #4: 472 RPM (min = 458 RPM, max = 939 RPM)
System Fan #5: 0 RPM (min = 0 RPM, max = 0 RPM)
System Fan #6: 0 RPM (min = 0 RPM, max = 0 RPM)
CPU: +37.0°C (low = +30.0°C, high = +90.0°C)
System: +25.0°C (low = +22.0°C, high = +48.0°C)
VRM MOS: +22.0°C (low = +20.5°C, high = +66.0°C)
PCH: +21.5°C (low = +18.5°C, high = +49.0°C)
CPU Socket: +21.0°C (low = +19.0°C, high = +56.5°C)
PCIe x1: +92.0°C (low = +76.5°C, high = +97.0°C)
M2_1: +0.0°C (low = +0.0°C, high = +0.0°C)
Note that I use the https://github.com/Fred78290/nct6687d/ kernel module though. The upstream one doesn't label many temps.
Hi Atemu, I check it and it do not say anything about PCIe. just Thermistor 15. And two of them exist one lower temp +69.5°C and other +94.5°C.
There's nothing further I can tell you. You'll need to figure out which parts those sensors correspond to to draw any sort of conclusion.
I'd recommend you try the out-of-tree driver I linked. You can just rmmod the normal one and insmod the custom one at runtime.
thank you, i will try to find out what is it.
Normal under load. Not normal at idle. Check the thermal paste if it's the CPU.
nctsomething is always the motherboard. the CPU is always a different sensor group
Hi Talidan, It is not underload. Im pretty sure it is not my thermal paste(i just builded the pc 4 months ago).
