Extra fan for Dual/Quad SATA HAT

#1

I got my SATA HAT with 2 fans, one is the top with a display panel and the other with metal cooler for the main board. The top fan works just fine, but no idea how to run the smaller fan? The manual says nothing abut it. Perhaps it should be controled through some particular pins, as it connects to extra power socket on SATA HAT, but there is no descrption in docs.

Hi Martin,

I assume you are using the Dual Quad SATA HAT with a Raspberry Pi 4? What strategy did you use to get your SATA HAT working?

e.g. did you use:

 sudo apt update
 sudo apt install python3-dev
 wget https://github.com/radxa/rockpi-quad/releases/download/0.3.0/rockpi-quad.deb
 sudo apt install -y ./rockpi-quad.deb

or the following:

curl -sL https://rock.sh/get-rockpi-sata | sudo -E bash -

Personally I’ve only tried the first method; and my best success was upgrading the package with a community version packaged by tomgehrmann.

As a side note, when you say the top fan works, does it spin at full speed or does it seem to regulate its speed with the CPU temperature?
