Raspberry Pi 5, Argon NEO 5, control fan

Configuration
1

Hi,

I’m looking for a way to control the Argon NEO 5’s built-in PWM fan. Here’s a link to the product: Argon NEO 5 BRED Case for Raspberry Pi 5 with built-in fan – Argon 40 Website Store

It looks like this solution don’t support the new case from Argon:

Could you suggest how I can control that fan?

The RPi 5 fan output is controlled directly by the its firmware:

No it is not possible to control the fan manually. Not on an integration level at least I guess.

Hi,

I have the same case. As far as a I know you cannot control the fan. But in another topic I found that you can set the temperature thresholds and speeds:

Raspberry Pi 5 Fan control

I tried this and it works. My fan starts at 25% at 40 degrees C and increases if the temperature rises above 3 more thresholds.

Thanks for linking. I decided to not play around the automatic fan control (Pi firmware controlled) but instead just use the default which is working very well for weeks now.

Anyway, good to know it’s possible to tweak the thresholds and speeds to have a bit control (if necessary).

EDIT:

@e-raser,
i have the same case and rpi5, i just want to read out fan-speed. Response appreciated, thanks
