Shows if the fan is currently active. The fan can be activated and deactivated manually by writing 0 (on) or 3 (off) into this file. However, both the ACPI code in the kernel and the hardware (or the BIOS) overwrite this setting when it gets too warm.

отдает управление кулерами обратно системе

There are no pwm-capable sensor modules installed

Shatur
можно ли как-то просто принудительно включить кулеры, не меняя настройки температур?

Switching off wifi: acer_ec.pl := 0x71 0x00 Manual fan speed setting: acer_ec.pl := 0x93 0x14 and then set the speed at 0x94 : 0x00 full, 0xff off acer_ec.pl := 0x94 0xbb <-- very low fan speed

Aivar
Если кулера не управляются програмно, а лишь на уровне BIOS - забудьте эту идею.

Morisson
- это значит, что кулер не управляется ШИМ. Скорость меняется ступенчато и управляется, как уже выше сказали биосом. Можно забить.

vasek
Скорее всего можно, но нужно смотреть и разбираться - если есть желание, почитай это, там же найдешь ссылки на дополнительные источники, которые помогут написать и скрипты, используя готовые для конкретного железа.

Morisson
perl-скрипт из твоей статьи не работает, пишет, что нужно установить какой-то модуль Sys::PortIO, строка 30 скрипта.

Я так понимаю, это влияет только на получение температурных показателей?
