先達の解析によれば、デバイスファイルに値を書き込むとファンの回転数をソフト的に変更できるそうで。その知見をありがたく使わせていただく。

回転数制御スクリプトを用意。エディタはCtrl-Kの後にSキーで保存、Ctrl-Cで終了。

# edit fan.sh
---- 中身：ここから ----
# 低回転エラー避け
#!/bin/sh
echo 1000 > /sys/class/hwmon/hwmon0/device/fan1_min

# 回転速度を0-255で指定
echo 64 > /sys/class/hwmon/hwmon0/device/pwm1_auto_point1_pwm
echo 64 > /sys/class/hwmon/hwmon0/device/pwm1_auto_point2_pwm

# 以下、メモ
#cat /sys/class/hwmon/hwmon0/device/pwm1_auto_channels_temp
#cat /sys/class/hwmon/hwmon0/device/pwm1_auto_point1_pwm
#cat /sys/class/hwmon/hwmon0/device/pwm1_auto_point2_pwm

スクリプト実行

# activate fan.sh

正しく記述できていれば、ファンが静かになる。

書き込む値と回転数の関係は下表な感じ。面倒なので全部は調べてません。
