software fan control
Hi, I have just built a mini-itx box with a jetway J7F4 motherboard. It's great, apart from the fan is a bit noisier than I had hoped - I bought it hoping that it would be quiet enough to leave switched on all the time in my living room, but it isn't. I've thought of just disconnecting the fan, as it seems to run fairly cool even with the CPU at full load - around 35 deg C, but I would rather not do this unless there's no alternative. Is there a way of telling the kernel to leave the fan switched off unless the CPU temp goes above a certain value, say 50 deg C? I had a look through /sys and found this directory: /sys/class/thermal/thermal_zone0 total 0 lrwxrwxrwx 1 root root0 2009-08-14 21:17 cdev0 - ../cooling_device1 -r--r--r-- 1 root root 4096 2009-08-14 21:17 cdev0_trip_point lrwxrwxrwx 1 root root0 2009-08-14 21:17 cdev1 - ../cooling_device0 -r--r--r-- 1 root root 4096 2009-08-14 21:17 cdev1_trip_point lrwxrwxrwx 1 root root0 2009-08-14 20:56 device - ../../../devices/LNXSYSTM:00/LNXTHERM:00/LNXTHERM:01 -rw-r--r-- 1 root root 4096 2009-08-14 21:17 mode drwxr-xr-x 2 root root0 2009-08-14 21:16 power lrwxrwxrwx 1 root root0 2009-08-14 20:56 subsystem - ../../thermal -r--r--r-- 1 root root 4096 2009-08-14 21:17 temp -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_0_temp -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_0_type -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_1_temp -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_1_type -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_2_temp -r--r--r-- 1 root root 4096 2009-08-14 21:17 trip_point_2_type -r--r--r-- 1 root root 4096 2009-08-14 21:16 type -rw-r--r-- 1 root root 4096 2009-08-14 20:55 uevent There are also directories cooling_device0 and cooling_device1, both of which contain the files 'type' (FAN), and 'cur_state' (1 for device 0, 0 for device 1).
