echo level 0 | sudo tee /proc/acpi/ibm/fan #(fan off)
echo level 2 | sudo tee /proc/acpi/ibm/fan #(low speed)
echo level 4 | sudo tee /proc/acpi/ibm/fan #(medium speed)
echo level 7 | sudo tee /proc/acpi/ibm/fan #(maximum speed)
echo level auto | sudo tee /proc/acpi/ibm/fan #(automatic - default)
echo level disengaged | sudo tee /proc/acpi/ibm/fan #(disengaged)

查看cat /etc/proc/acpi/ibm/fan

设置为2后,声音小多了。
