Fan Control 1.1 http://www.lobotomo.com/products/FanControl/index.html
關於在Windows XP的應用性,當從OS X重新開機到Windows XP(如果你有裝的話),風扇轉速會固定在OS X最後系統結束前韌體內的轉速設定,也就是smcFanControl的最低轉速設定或者Fan Control動態設定最後一次的寫入值(不很確定),只要在Windows下不重開機,不進入休眠,風扇值就不會跑掉。但是如果你用的是Fan Control 1.1而且反應曲線設得很靈敏的話,風扇可能一直都會在3500~4000rpm左右,也就是換到XP時,還是有一點聲音,而且到了XP下風轉轉速就不會隨溫度變化而改變了。
哪個好用?看個人囉!如果你只有用OS X,我覺得Fan Control 1.1比較好用,因為你可以設定風扇轉速對溫度的反應靈敏性,不必設定得太靈敏,不然風扇很容易到3500 rpm以上。當然如果要簡單的方式用smcFanControl 1.12也很好,只要設定最低轉速,其他的交給MBP,不過MBP的原始設定不容易拉高風扇轉速,但是話說回來,最低值設成3000 rpm 時就很好用了,溫度也不會太高,也不會聽到噪音。但是,如果用Fan Control 1.1的話,你可以把最低值調低到1000轉,但是溫度閥值最低也給它靈敏些,用40度,這樣你平常工作時也會跑2500~3000 rpm,但是當你工作量很少時,或者辦公室冷氣變強時,轉速可能可以降比較低些(要測試才知道),也許對於風扇壽命有幫助,但是如果用smcFanControl,轉速就永遠不會低於你設定的最低轉速,而為了降溫效果,又不得不設成2500~3000 rpm,我不知道長期下來會不會比較傷風扇。
但是如果你用Windows XP時,smcFanControl可以確保轉過去時風扇不低於你的最低轉速,在Fan Control 1.1下面如果你最低轉速要調低於三千轉,也許轉過去時風扇速度不足以在Windows下有效散熱喔!那就考慮考慮看看,兩個都可以玩玩。我想要移除程式只要丟到垃圾桶就好了,Fan Control你可以在資源庫的PreferncePanes找到。
Well, just let you guys know. smcFanControl的作者有解釋為何他的程式只能設定最低轉速,其他的交給MBP原本的auto設定,而不作成動態讀取溫度調節轉速。以下是作者Hendrick的說法:
Wouldn't it be even better to read out the temperature and set the fan speeds depending on the readout than just set the minimum fan speed and let automatic fan control as defined by apple do the rest?
Yes, that approach is even better and could make your machine running cooler, when you are at higher loads. BUT: I did not take this route for smcFanControl, cause it has some risks. Adjusting the fan speed to CPU temperature requires you have a program running in the background (e.g. a daemon) that adjust fan speed continuously . If that program ever crashes or becomes incompatible cause of a System Update, the fans would get stuck at a certain speed and this could probably damage the machine.
所以,大家看看要選哪一個囉!
另外有人說
Fancontrol is as safe as smcfancontrol. Uses the auto mode the same as smccontrol, but lets you adjust the minimum fan speed and the ramp up.
