EVGA I/O Fan

post #1 of 3
Thread Starter 
I was looking at the EVGA FTW Z68 motherboards, and noticed a little fan that seems to mount to the I/O shield.

What on earth is it used for?

It's used to exhaust potentially trapped warm air generated from the mosfets (for those who don't have a case with good air flow). It is optional.
