Enermax Twister 120mm Fans Review

A closer look

I have to admit, that Batwing design is pretty gnarly.  They almost give it an aggressive look.  Then there’s the aluminum ring that makes up the frame.  Enermax has cut their name out of it, giving it that customized feel.  However, I don’t see how this is going to do much more than disrupt airflow rather than improve it.  Air moving across a smooth surface moves with less turbulance than when it moves across an uneven surface.  It’s standard scientific fact.  But we shall see what happens.

Okay, so let’s start by examining the product and its packaging.  It comes in a tradition blister pack, but rather than having to slice and dice your way into this one you can simply pull it apart after removing the stickers that hold it together.  Take a lesson here, you other blister-packers:  Your packaging sucks, offers almost no protection, and is a pain in the ass to open.  Enermax did it right in this area for sure.  Okay, you have the fan out.  Underneath that is the information card which doubles as the container for the instruction booklet.  At the bottom of the packaging is a little zip baggy which contains a 3-pin fan to 4-pin Molex adapter, four fan screws, and four isolator mounts for those who would rather have them over screws.

Installation is little more than your basic screwing and plugging job.  Even if you use the isolator mounts, you’re still in for an easy job in the long run.  Actually, it’s quicker than if you had to tighten down all those screws.   Then I plugged the fan into my fan controller so I could check out the dB levels at different speeds.  The whole process took me all of eight minutes, including using the screws.

On the next page we test the fans…

    If ya think this one was good, review the T.B. Silence UCTB12 at 12VDC 900 RPM- 71CFM at 11dB, which is what I use to replace my Thermaltake Armor MX VH8000BWS case fans with and added a third one to the top cover where the toolbox was.

    The airflow dB ratio is on par with the best silent fans available. What makes this design spectacular is the airflow pattern. The typical fan moves air in a cone shape outward from the edges of the fans frame caused by the Coanda Effect as air moves through the venturi. The Bat-Wing blade design moves air through the center of the fan, making it particularly useful for heatsinks.
