Приветствую!
Столкнулся на днях с особенностью - решил измерить температуру процессора. 82 градуса по Цельсию.
Ноутбук - Samsung R503 + дополнительная подставка с большим вентилятором. На нем стоит CentOS 6.2. (К слову - с WinXP такой температуры даже близко нет на данном ноутбуке).
Загуглил, узнал про cpufreq, настроил на 550 MHz (на политику conservative). Температура упала до 81. Но это все равно очень много.
Возможно, есть еще какие-то способы?

analyzing CPU 0:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 1000 ns.
hardware limits: 550 MHz - 2.20 GHz
available frequency steps: 2.20 GHz, 1.10 GHz, 550 MHz
available cpufreq governors: conservative, ondemand, userspace, performance
current policy: frequency should be within 550 MHz and 1.10 GHz.
The governor "conservative" may decide which speed to use
within this range.
current CPU frequency is 550 MHz (asserted by call to hardware).

(Ну яичницу не пожаришь, но от тепла от вентилятора тает быстро шоколад или чай не остывает ниже определенной температуры. Проверно путем проб и ошибок.)
