No veo la diferencia de velocidades, es la misma.

Well, the small fans are kind of useless. The big one is not that great either as the max rpm is laughable. It looks cool, but that shouldn't be the main priority in a cooling pad. The only positive aspect of the product is that the big fan is right under my laptop's cpu and gpu so probably it will do a little better than my former cooling pad. Right now can't tell a big difference. It is really quiet by the way. The price is ok so it isn't a big loss.Edit: it is now worth any money. Terrible design, it is not suitable for 17 inch laptops. I've got msi raider and using the cooling pad with my laptop is a nightmare. Cheap stands/baffles don't hold the device firmly so it slides laterally all the time. It's difficult to get to the button and scroll of the pad because of the laptop's size. Also it wobbles up and down when I'm typing. To conclude, terrible design and ergonomics, and what worse, the colling effectiveness is not great too.

Be aware. Fan speed does not adjust. Otherwise works fine, fan speed is adequate and fairly quiet. I've had noisier. Quite sturdy w/17" laptop. Switches and usb port hard to reach when computer is on it.
