Raspberry Pi (192.168.1.24) – fan noise investigation + fix

TL;DR

Pi fan was spinning unnecessarily high at normal temps. I implemented a simple temperature→PWM curve via a systemd timer.

Observations (during investigation)

CPU temp: ~55–60°C
Fan sensor: pwmfan (hwmon1)
Before: pwm1=75 → ~2630 RPM at ~56°C
Test showed lower PWM reduces RPM on this box:
- pwm1=60 → ~2125 RPM
- pwm1=45 → ~1260 RPM
- pwm1=35 → ~770 RPM (still stable at ~56–60°C)

What I changed (on the Pi)

Created:

/usr/local/sbin/pwmfan-curve.sh
/etc/systemd/system/pwmfan-curve.service
/etc/systemd/system/pwmfan-curve.timer

Enabled:

systemctl enable --now pwmfan-curve.timer

The curve (PWM 0–255) ramps up aggressively above 70°C for safety.

Safety notes

The script forces pwm1_enable=1 (manual mode) and sets pwm1 based on CPU temp.
If you later install another fan controller (fancontrol / vendor service), ensure they’re not fighting.

Docker “extract cleanup DeadlineExceeded / RST_STREAM CANCEL” errors were seen during a large pull; Docker later successfully pulled images.

Follow-ups

Consider moving Zabbix off the Pi (saves ~600MB DB data) once target host has disk headroom.
