External or other cooling options?

[Edaan]

So ive been beggining to notice that as soon as my laptop begins to get hot it tends to slow down very significantly. Ive resorted to putting a book under the back end of it to tilt it up and it seems to make a big difference in keeping it cooler.

What else can you do to keep your laptops cool? We need some sort of superpowered fans...

The Moshi Zefyr looks like it would work quite well.

There is a solution which is cheaper and sometimes more effective than notebook coolers. And of course it doesn't compromise portability:
Undervolting

You can use CoolBook for undervolting your cpu .

Advantages of Undervolting:
Same performance,
lower temperatures,
less fan noise,
longer battery life,
prolong notebook life(because of lower temperatures)

Disadvantages of Undervolting:
NONE
(as long as you don't lower the voltage too much. Even if you do lower the voltage TOO much , you can't do Hardware damage to your notebook,the worst "damage" you can do is just a restart . )
