Hi Dmitry, > > Which kernel version are you using? > > 2.6.11.5 Unfortunately, this kernel version does not have support for fan polarity fix yet. You will have to upgrade to 2.6.12-rc2 or more (I would suggest -rc4, obviously). > it87 3-0290: detected broken BIOS defaults, disabling pwm interface So this means that your BIOS did not program the PWM settings properly (or at least we think it did not). You should first search for a BIOS upgrade for your motherboard. If none is available, you should contact Gigabyte and tell them about your problem. Then, if all of the above failed, you may upgrade to 2.6.12-rc2 or later and try: modprobe it87 fix_pwm_polarity=1 Note that this is still experimental, so be very careful that your fans don't stop. You should now see the pwm control files in /sys, and if the workaround works for you, you should be able to control the speed of your fans. Hope that helps, -- Jean Delvare
