Hi list, I have some problems with setting the fan speed on my hp d530 desktop. I saw a ticket (closed) in the tracker #1837 which said it was examined/resolved in lm_sensors 2.8.8 Linux 2.6.9. I'm using sensors 2.10.0 with kernel 2.6.15-1-686 (debian-testing) and I can't get it to work (and the cpu fan sounds like a vacuum cleaner, doing its best to drive me nuts). I get reasonable data from everything but the fans: # sensors adt7463-i2c-0-2e Adapter: SMBus I801 adapter at fc00 V1.5: +0.000 V (min = +0.00 V, max = +3.32 V) ALARM VCore: +1.339 V (min = +0.00 V, max = +2.99 V) V3.3: +3.283 V (min = +0.00 V, max = +4.38 V) V5: +5.111 V (min = +0.00 V, max = +6.64 V) V12: +0.125 V (min = +0.00 V, max = +15.94 V) CPU_Fan: 0 RPM (min = 0 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) fan4: 0 RPM (min = 0 RPM) CPU: +34.25?C (low = +50?C, high = +55?C) ALARM Board: +39.00?C (low = +45?C, high = +50?C) ALARM Remote: +60.25?C (low = +60?C, high = +65?C) ALARM CPU_PWM: 57 Fan2_PWM: 255 Fan3_PWM: 255 vid: +1.387 V (VRM Version 10.0) There are no _div-files for the fans: ls fan1* pwm1* fan1_input fan1_min pwm1 pwm1_auto_channels pwm1_auto_pwm_freq pwm1_auto_pwm_min pwm1_auto_pwm_minctl pwm1_enable Running pwmconfig fails with "echo: write error: Input/output error" for all three (gives that when trying to write to pwmx_enable). I know it's possible to control the fans as the co worker having this box before me ran windows and he told me he ran some app to limit the speed but I can't figure out how to do it in Linux. Anyone that has a clue? Thanks Jon
