I used that very Antec fan on my last laptop. It worked OK.

Like Ramses II CP advises, I recommend you study the actual airflow scheme of your laptop first: does it exhaust out the rear of the machine, or the bottom? If out the rear, the Antec will do you little good. If out the bottom, it will help. If you go with the Antec, be certain it's "pointed" the right way, drawing hot air away from the lappy, not toward it.

I had mine tipped at about a 15-degree angle to allow the hot air room enough to blow away.

On the plus side, that Antec's USB plug is a piggyback type, allowing you to still have an open USB port.
