my fan goes on all the time macbook pro Macbook Pro - Fan Always On? I have a macbook pro and my fan is almost always on and the bottom gets way too ****ing hot! I HATE IT. But the pros outweigh the cons so I'm not going to switch laptops. Plus I'm in the design industry which is ruledby Apple.
There were problems with it overheating, crashing in hot countries but it's been fixed for almost a year at least.

I still am hearing the fan is constantly on, but it's not overheating or everything, it's just very hot. I have complete confidence that the Macbook will not overheat, but it's just the fact of that annoying fan always on. QUOTE (quack @ Dec 13 2008, 11:15 PM) What about the new Macbooks?

Check the Apple support site whether it's mentioned as a problem or how the reset the power controller.
Ummm, guys, the fan for ALL computers should ALWAYS be on or else it'll lead to a system crash. All Macs have always been cooled by a fan. However, at what speed should be the question. The standard minimum speed for a fan to operate on an Intel Mac should be 2000 rpm. The highest (and should be worried depending on application) is 6000 rpm.
On the polycarbonate Macbooks, it is normal to see YouTube videos causing the fans to rev to 6000 RPM due to the fact that the Intel graphics chipset just suck and forces it to be fully rendered on CPU instead of offloaded to the GPU as well. As for the Macbook Pro, they usually range from 2000 rpm to 3000 rpm as their normal operating speed. You wouldn't even hear the fans loudly until you hit 4000 rpm. xboxrulz QUOTE (xboxrulz @ Dec 16 2008, 11:47 PM) Ummm, guys, the fan for ALL computers should ALWAYS be on or else it'll lead to a system crash.

It's very common for laptop to turn off the cpu fan when the cpu temperature is below a certain value (40° - 50°). I can keep my cpu fan off till it hits 50°c and my laptop still runs stable  . In fact, your cpu must be at a certain temperature before the cooling system becomes efficient. The heatpipes in your laptop (same goes for desktop coolers) are useless at lower temperatures.
I have yet to see a laptop due that if they are manufactured from 2007 onwards.

I don't know about macbooks specifically but my laptop fan turns on and off periodically. The heat sensors automatically switch the fan on after it exceeds a certain temperature.
Most laptops do start to feel a bit hot after a while but that is pretty normal and everything should still run stable. My friend who recently bought a macbook hasn't really had any problems with overheating as far as I've heard.
Yes, resetting the SMC may or may not fix it. If it does, then excellent. Else, send it to an Apple Store or call AppleCare for details.
