fan safety

realized my MBP was super hot so I got smc and it works beautifully.

I honestly don't mind the fan being louder with the peace of mind knowing my computer runs cooler.

so theoretically, the higher the RPMs run on my fans, the sooner they wear out.

so here are some questions:
1)who hear has been running their fans higher? what RPM and for how long?
2)what is a safe RPM to run your fan where it will not prematurely wear out?
3)if my fan wears out/malfunctions, is there a safety feature in OS X where my computer will shut down so that my computer won't burn out?

thanks!

First it's not just the MacBook or MacBook Pro which run warm, it's most notebook computers that do. Some have better cooling than others.

Running your fans higher will keep the CPU (and the machine) generally cooler but also increase wear on the fans. (not withstanding the increase in noise) Normal fan speed is around 1800 RPM at around 50 degrees C.

Running the Fans between 2000 - 2500 RPM should not significantly increase wear and tear while at the same time keep the noise level down.

As for safety, if the fans quit so will your machine. Built in thermal protection will not allow the CPU to function without the fans providing cooling.

Have you thought about alternate ways of keeping your MBP cool? Cooling stand, keeping the lid open, not using it on a carpet like surface or your lap, and so on?

Regards.

i never use it on a carpet-like surface

i just want to know if my macbook pro will auto-shutdown if the fan fails while it is on

i do not mind the noise at all while running it at 4000rpms

but will 4000 rpms cause the fans pre-maturely wear super quick or will i get a good 3-4 years out of it? which is the reason for question #1 on the first post.

thanks

The best thing to do is the leave the machine alone to manage itself. I am quit sure than running the fans at 4,000 RPM full-time will increase wear and tear over an extended period of time. I would not recommend you doing that unless you live in an extremely hot environment.
