I am not sure if that's really a good idea.
If you are sucking in the air from behind your computer, you are just sucking in the air that is being blown out from AGP fan, Case fan, and PSU fan.
And most of the time, your computer is placed close to the wall and you won't get enough fresh between your comptuer and the wall.
Does your GPU have its own fan?
How many intake fan you have on your case?
How many outtake fan you have on your case?
Is there any other fan then case fans?
You've made several incorrect assumptions my fellow ATer.
First of all, the only fan blowing air out the back of my machine is my PSU at the top (my other outtake is in the top of the case) and this PCI slot intake fan would obviously be near the bottom of the PC.
Secondly, I never position the back of a PC closer than about 1' to a wall if I am concerned at all about temps (stock internet surfing computer, maybe). That allows plenty of air-flow to support something like this (1' is more than what you have inside the case).
1. Of course GPU has a fan on it but to answer the question I think you meant to ask, no it's not an intake/outtake fan, it just uses in-case air and allows it to stay in-case afterwards.
2. I have 2 intake fans (120mm and 90mm)
3. I have 2 outtake fans (120mm and 80mm)
4. Internal fans (not intake or outtake) include GPU fan, CPU HSF, and chipset HSF (perhaps my DVD burner has one of those tiny fans in the back of it, I'm not sure).

So long as it is lower than any exhaust fans it should do something. That heat rises thing and all.
That was my thinking. And even if I had a VGA outtake fan I could simply place a divider (aka a couple inches piece of cardboard) on the outside of my case to force the air to not go down initially.
Anyways, I wasn't asking you to tell me whether this is a good idea or not (I can tell you that for me it is a good idea). I was asking if these things exist.
