For those of you who are really concerned about the heat of the macbooks are giving out, here is a very effective solution that's been discussing on Apple's official macbook forum. It actually originated from an post in the official MBP forum:
Apple - Support - Discussions - My macbook idles at 30c. Here's how ...
I personally think this is just something a lot of us have been waiting for! ! After using it, my Macbook barely even gets warm! What a great difference! I figured we should spread the news.
Cheers!

There must be some downsides.

As far as i can see, no downsides! All it does it allows you to change the minimum rpm of the fan from 1500rpm to what ever you want up to 6200rpm. Obviously if you crank it up it gets pretty noisy!

I found that as long as the fan speed is lower than 3500rpm, the fan is almost inaudible. I set mine to be 2500rpm and found its sufficient already. Also, Other people have reported that increasing the minimum fan speed to 3000rpm did not change the battery life.

I cranked it up to 3000rpm and haven't really noticed a difference in temperature...

hehe. Your Macbook must have been cool enough already. What was the average temp before?

OK, so for example, I put my fans on at 3000 RPM. What happens when I am doing heavy work which requires the fans to be on more than 3000 RPM? Do I have to remember to manually set the fans higher or else get a broken machine, or will the machine automatically increase fan speed..

It's supposed to change only the minimum setting. The max will be whatever is required according to the load on the CPU, so it shouldn't be affected.

Sorry for posting this twice. I accidentally refreshed the "submit" page.

No. You don't have to. What you are changing with this program is ONLY the MINIMUM fan speed, namely, the baseline of your fan behavior curve, not the curve itself. And to play on the safe side, the smallest value you can set to is already the default value set by Apple so you won't get any chance to screw your macbook up by lowering the fan speed.
The problem with macbook and macbook pro is that the default minimum fan speed, 1500rpm, is too low for them (or you can say the threshold temp of cranking the fan speed up is set too low), which consequently causes the high average CPU temp many users have been complaining about.
It's either that Apple was overconfident about their heat dissipation design or that they worried too much about the possible fan noise at a higher speed. As i said in a post above, any value slower than 3500rpm is almost still inaudible.
