New Fan Adapter that might actually be of use

[Sorgon2]

I came across this item and thought it looked kinda cool. I know some say fan adapters are worthless, but this one come with added features not seen b4. It is called the ICEHOLE. It has an RPM(voltage) switch. Also, which I thought was nifty for those that have windows, it comes with LEDs to light up this sucker. An interesting gadget.

Really cool, But I doubt about the cooling efficiency.

So, fan adapters have a big impact on their performance? Is it just better to mount a larger fan without using an adapter?
