答案1
Thermald？这是为了保持电脑凉爽……它默认使用皮肤温度传感器（我的电脑没有，所以我将它设置为查看 CPU 温度传感器）。你给它输入一个值，它会尝试将其保持在该温度或低于该温度（或多或少，如果升温很快，它可能会超过几度。）
如果您的 HP 具有风扇控制功能，那么这可能会使风扇加速并消耗更多电量。但如果它没有风扇控制功能（或者您可以禁用 thermald 对风扇控制的使用），它会非常有效地使用 CPU 节能模式和节流。
我有一台或两台戴尔电脑，我可以用这款软件找到一个最佳温度，让电脑温度降低 20-30 摄氏度（在 CPU 上，但机壳也冷却了很多）。如果我运行 CPUBurn，它会以 50-60% 的速度运行……但如果我运行任何其他使用 100% CPU 的程序，它会以 90-100% 的速度运行（任何低于 100% CPU 使用率的程序都会以 100% 的速度运行）。我插上电源使用这款电脑（只是想让它运行得更凉爽），但这必须转化为一些电池电量节省。
