I haven't figured out how to turn it back on. :-) pwm1 = pwm2 = 0 is fan stop pwm1 = pwm2 = 255 is fan full speed pwm1 = 0; pwm2 = is variable speed where is between about 60 which is the lowest value at which the fan will reliably start rotating and approx 100 which seems to be full speed.

Then I wrote 0 to both files, redundantly. This actually turned the fan off! Writing 255 to pwm1 turned it back on. Followed by 255 to pwm2, with no change. Now both files have 255. If I echo 0 to pwm1, it turns off, 255, turns it back on. Looks like the pwm* arn't getting a value on boot that matches the state of the fan? -- see shy jo signature.asc Description: Digital signature

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.

In my system, the command would be: cd /sys/class/i2c-adapter/i2c-0/0-002e/ and execute the following command there: grep . * The command is a trick to print both the name and value of each file in this directory.

I won't have time until tomorrow night to open the case and take a look at the fan connector, so I can't say at the moment what that looks like. Yes, this is a very new machine, it arrived about a week ago. It had the v2.1.06 firmware, which I think would point to a quite recent manufacture date. Maybe all I can do for now is wait and see what others report on the recently manufactured N2100's Thanks for the help!

Hmm... I can only think of three reasons it's not working then: 1) The hardware is broken somehow. Mine has a 3 pin fan connector, does yours and is it plugged in correctly? 2) There is a bios setting of some sort that has disabled fan control - but I have no idea how you'd check that unless redboot has a mechanism. 3) The design got changed, is your N2100 very new (or perhaps very old)?
