Okay, I know that's retarded, but that's basically the way it works. The pad has little risers on it and the 8886 has risers on the back to create the '******' space where air flows. The Lappy brings air UP from that space and out the '^^^' (supposed to represent the right side of the 8886). The cooler pad brings air down through the '~~' (fans) and blows it out the back.
(btw, the space between is exaggerated)
The point I'm getting at is that ****** (the air) has to come from somewhere because that air has to be there. The only place the air can be taken from is out the front/sides/whatever---around--the laptop. New air (room temp) is constantly being drawn in from all around the laptop. Now, neither set of fans is anywhere near powerful enough to create even a partial vacuum of any significance, IMO, except of course to create the partial vacuum that draws in air from around the laptop.
Now listen, I'm not trying to suggest that this cooler pad is extremely effective; it probably does little more than someone blowing on the thing--but I don't believe the physics of the thing are incompatable w/ the 8886 either (and I think the pad does have some cooling value). But seriously, there's no way the fans working in tandem create "less air" and somehow limit the normal cooling of the 8886--that's just not possible w/o a (mostly) airtight system. I know that no one said that it would diminish the cooling of the 8886 system, but the logical extension of what people are saying would make that a necessary consequence.
Alrighty then... If before was my two cents, that was my buck-fiddy's worth...
