The fan is plugged in and running at apparently full speed. (Although, before I put debian on it, at one point the box beeped long and loud and the firmware complained that the fan had failed. It seemed to be spinning when I checked. Odd.) It is a 3 wire fan. I was able to at least turn the fan off by echoing things to the pwm* files. I haven't figured out how to turn it back on. :-) root@turtle:/sys>find |grep pwm ./class/i2c-adapter/i2c-0/0-002e/pwm2 ./class/i2c-adapter/i2c-0/0-002e/pwm1 root@turtle:/sys/class/i2c-adapter/i2c-0/0-002e>cat pwm2 0 root@turtle:/sys/class/i2c-adapter/i2c-0/0-002e>cat pwm1 0 root@turtle:/sys/class/i2c-adapter/i2c-0/0-002e>grep . * fan1_exp:247 fan1_input:5949 fan1_max:159 fan1_min:0 fan2_exp:247 fan2_input:159 fan2_max:159 fan2_min:0 in0_input:1720000 in0_max:2040000 in0_min:2040000 in1_input:1336000 in1_max:2040000 in1_min:2040000 in2_input:1720000 in2_max:2040000 in2_min:2040000 in3_input:904000 in3_max:2040000 in3_min:2040000 name:F75375 pwm1:0 pwm2:0 temp1_input:38000 temp1_max:60000 temp1_max_hyst:55000 temp2_input:38000 temp2_max:60000 temp2_max_hyst:55000 -- see shy jo
