Port/Peripheral information

N/A

Standalone Operation

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• No

Describe the bug

Fan RPM ramp-up is now very very delayed while the processor is virtually at 100 deg C

Steps To Reproduce

• While running stress-ng -c 16:
• Watch temperature by periodically running sensors

Expected behavior

Previously the fan would quickly spin up.

Regression behavior

Fan does not spin up for a long while (seems over a minute) while the processor is at 100 deg C according to sensors.

Operating System (please complete the following information):

• OS/Distribution: Fedora Workstation
• Version: 42
• Linux Kernel Version: 6.14.6-300.fc42.x86_64

Additional context

Laptop is on a stand/arm which leaves some space beneath so there is airflow into the fan intake.

Hey Dimitris. Yeah, we noticed this behavior on another project, we have some ideas on how to fix it, it should be applicable to your device too.

In the meantime you can use something like sudo ectool pwmsetfanrpm or sudo framework_tool --fansetrpm to manually adjust the fan before you expect a sudden load (but i'm sure that will get tiring quickly). You can set it back to auto once the slower fan temperature sensor catches up with reality.

Fan does not spin up for a long while (seems over a minute) while the processor is at 100 deg C according to sensors.

What do the rest of the sensors measure at this time when the CPU is not but the fans aren't on yet?

You can nicely log them with sudo s-tui --csv -r 1

@JohnAZoidberg here you go:

s-tui_log_2025-05-18_18_50_00.csv

and because I'm lazy today not that great with spreadsheets, Claude's visualization of temp and fan readings (forgot to say "briefly" in the prompt so it went a bit above and beyond but oh well):

Edit: all sensors included:

Overall this feels/looks better than last time I tried stress-ng. It's on a fresh boot after some updates that don't look super relevant to me:
