Building my own laptop cooler...fans need to be push or pull?

[AndroidVageta]

So Ive decided that after looking at prices for laptop coolers, which are arguably ridiculous, Ive decided to design and build my own. My design is most likely going to be as or more effiecent than any design Ive seen so far as well, so all is good.

Question I have though, is that should the fans blow air ON TO the bottom of the laptop or suck air out? Im pretty sure you would want the fans sucking air out as the forces the hot are out of the laptop instead of blowing on it, which to me would seem to not do too much in terms of cooling...

Below is a ROUGH design of my cooler:

I feel that having the laptop sitting on a mesh like material with the fan below it in a boxed setting will cool the whole bottom of the laptop much better than some coolers out there where the fans are just right on the surface...I feel like having a mesh top to the cooler allows the air from all the vents on what not to be properly sucked out....

I dont know, seems like a easy enough idea and simply a easy enough object to build.

No one knows? Thought this as a basic question...

Most of the laptop fans I've seen blow air out of the sides. Whether or not they suck air in through the bottom (or blow air out of there as well) is dependent on the chassis design.

I'd personally design the fans to blow on the laptop. If nothing else, the air will remove the radiating heat from the bottom of the laptop and allow it to escape out the front, back, and sides - similar to how a pedestal fan keeps you cool when it's blowing on you.
