我有一个在双重引导配置下运行Ubuntu 10.04和Windows 7 Starter的Dell Inspiron Mini 1012。
即使在CPU处于空闲状态时，其在Windows中运行的温度也比在Ubuntu中低得多。例如，我在Ubuntu现在，在CPU已经空闲了一段时间，并且CPU温度是根据72℃ lm-sensors和coretemp。
实际上，这台计算机实际上只是在Ubuntu上过热了，只是因为CPU长时间处于100％运行状态。同样，此问题仅在Ubuntu中发生-我从没注意到Windows中的高温问题。
我已经尝试使用CPU频率缩放监视器GNOME小程序将CPU速度设置为1GHz（而不是1.67GHz）和Powersave模式，但这似乎并不影响空闲温度。

是否有人对我如何使我的CPU在Ubuntu下运行冷却器有任何建议？

The program 'upowerd' is writing to file 'history-rate-DELL_2T6K207N-52.d' on `/dev/sda5`. This prevents the disk from going to powersave mode.
