XtremeMods checks out the TT Smart Fan II... This thing is probably the best
80mm fan on the market in my opinion. About the only TT product I like.
Some nifty functions that come with this fan are the fan speed
modifiers. You can either control the fan speed by an analog dial, which attaches
to the fan by a two pin connector, or by a thermal sensor which you can place
anywhere within cable reach.
