With the release of the MacBook/Pro line from Apple, it has been welcomed with either open arms or heavy criticism because of the fact that Apple’s not calling them laptops anymore — but notebooks. That’s because of the ammount of heat some of these so-called notebooks generate even when on an idle state. And, well, someone over at the MacRumors forums found a way to modify some .kext files to increase the fan speed within the notebooks.
User Rokem even built some AppleScripts to automatically set the fan speeds up to your liking. A direct link to the download is available here.
In the forum thread, several users are reporting amazing temperature drops of up to 40ËšC in their MacBooks/Pro. In my case, I never actually had that bad of a problem since my MacBook Pro stayed at 45ËšC when I’m doing minimal ammount of work on it (think text editing) — but now, when I set the fan speed to 3500rpm, it’s been lowered to 35ËšC (a full 10ËšC drop!). I’m just as happy with these results as the other users.
There’s even talk of adding a graphic interface to these AppleScripts.
Now, just a word of caution: when tweaking around your MacBook’s system files, just be sure to know what you’re doing — since something may end up doing more harm than good to your MacBook.

Wow! It’s amazing to see people are getting that kind of result, without any problems. If only I could muster up the courage to attempt the hack.

CoreDuo Temp is an app to view the current temperature of your CoreDuo CPU. You can find it here.

a lot easier

Yeah, SMC Fan Control rocks! It just didn’t exist when this was published
