如何使用 i8kmon 配置限制笔记本电脑风扇的速度？

Question

我的 Dell Inspiron N5110 笔记本电脑过热。为了解决这个问题，我使用了 i8kutils，其配置如下：

 # Run as daemon, override with --daemon option
set config(daemon) 0

# Automatic fan control, override with --auto option
set config(auto) 1

# Report status on stdout, override with --verbose option
set config(verbose) 1

# Status check timeout (seconds), override with --timeout option
set config(timeout) 1

# Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
set config(0) {{1 1} 30 59 -1 40}
set config(1) {{2 2} 60 128 53 128}

我想让风扇一直以中速运转，除非温度超过 60 度。但使用此配置，即使温度只有 55 度，风扇也会高速运转。

它看起来是这样的：

1411306941 acpi: Battery 0: Full, 100%
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0
temp, left, right, ac state: 54 2 2 0

等等。有什么建议吗？
