I have a work around which I can confirm works on my Latitude E5500. 1. Download the i8kutils *source* package with: cd ; sudo source i8kutils 2. In the created directory build the smm tool with: make smm 3. To turn off bios taking control of fans run: sudo ./smm 30a3 4. You'll need to do this every time you restart, so put it in a startup script somewhere.
That's it, but if you want to re-enable bios control of the fans, run: sudo ./smm 31a3 I'll copy this notice about the smm tool from smm.c: * WARNING!!! READ CAREFULLY BEFORE USING THIS PROGRAM!!! * * THIS PROGRAM IS VERY DANGEROUS. IT CAN CRASH YOUR COMPUTER, DESTROY DATA * ON THE HARDISK, CORRUPT THE BIOS, PHYSICALLY DAMAGE YOUR HARDWARE AND * MAKE YOUR COMPUTER TOTALLY UNUSABLE. * * DON'T USE THIS PROGRAM UNLESS YOU REALLY KNOW WHAT YOU ARE DOING.
