TechREACTION Review: Enermax ETS T40 HSF
 

The fan included with the Enermax ETS-T40 has a 4-pin power connector. Style wise, the fan has "Enermax" cut into the side, which is a feature that seems a little neglected without a backlit fan. Don't worry though, Enermax has you covered: they also make a version of the ETS-T40 (the ETS-T40-TA and VD) which have backlit fans.
