Debian CM3588 - Fan control settings

[xrs]

Hello, I have recently acquired a CM3588 board. I have successfully installed debian with the provided image:

Code: Select all

rk3588-eflasher-debian-bookworm-core-6.1-arm64-20240522.img.gz

Setting up ZFS with 4 SSD slots was easy following this great guide:

However, I have noticed the fans are not engaging although the board gets quite hot. I have tried enabling fan control by following this SO answer:

https://askubuntu.com/questions/22108/h ... -fan-speed

However the

Code: Select all

sensors-detect

command fails to detect any devices:

Code: Select all

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
https://hwmon.wiki.kernel.org/device_support_status for driver status.

Any tips or information regarding the status of fan control?

Is the only solution to use the GPIO pins? I spliced the tiny connector into the 80mm fan I bought for the case and it works with the Debian install the OP also used, but not until CPU0 hits 50C. I'd just like to be able to adjust that fan curve a little. But I can't find anything anywhere on the fan controller, pwmconfig doesn't even seem to be installed by default.
