New 'Modified' Notebook Cooler, NotePal W1...

During the 3rd day of Month of Syawal... I have collected some 'duit raya' to buy a notebook cooler.
I kept my desire to have a notebook cooler since my old notebook because when a notebook gets too hot, the performance will go down. So, i had bought my 1st Cooler Master product, NotePal W1.

The price goes to the material, aluminum.

One thing that arkward about the cooler, it blows air into the notebook. I realized it after a few hours of using it, I don't feel any changes of the heat on the notebook surface. 
Somemore, the CPU fan sucking hot air out from the notebook yet the notepal blowing air into the notebook. By matching the fan's speed, the notepal is faster than the CPU's. CPU's fan will lose, and it might damage. So, I think that there is something wrong.

So, I remove the fans and reverse it. All 3 of the fans are now sucking air out from the notebook.  

Now, I have my notebook lay with a comfortable angle and a cooler surface with a better performance.

Anyway, my doubt is, why does Cooler Master Notepal W1 blows air into the notebook rather than sucking air out?
