Input:
I can't speak to the longevity of the fan, but week 1 I love it.  I put it under my video card and instead of that hot air staying in the case, it's blown out with this fan.  When running a game, you can feel hot air blowing out.  I'm running 7 degrees Celsius lower on my GPU, and about 4 degrees on my hard drive.  For the price, it's well worth it and will likely pay for itself several times over by increasing the longevity of your components.
