Noise, Performance and Thoughts
Noise and Performance
Although we have no way to truly test how well the Dual Storm performs, you can feel that with the fan setting set to its highest level, the devices seems to shift a lot of air out of the case. At its lowest settings, the amount of air moved is much less noticeable, but still reasonable.
From a noise perspective, setting the fans to 'Low' leaves the fans
running at a reasonable noise level, certainly nothing particularly
noticeable over the general noise of a running system. Set to high
however, the noise emitted from the Dual Storm does become much louder,
and is definitely much more noticeable.
Thoughts
As case fans go, Cooler Master's Dual Storm certainly has something different to offer - The dual fan capabilities of the part give both the ability to move a lot of air and redundancy in the case of one of the fans failing. Add in to that the fancy styling and blue LED, and this may be something that will tickle the fancy of some users.
On the other hand, the Dual Storm does have its shortcomings too. Firstly, the short cables to the fan speed controller do limit your options with regard to where you place this control. More importantly for many may be the noise - If you want the Dual Storm to run at full tilt, you'll have to put up with the rather loud noise levels. Finally, the lack of an installation manual is almost criminal. Luckily, installation is simple enough, but the lack of even a single page detailing the process is very disappointing.
Overall though, if the more unique principles behind the Dual Storm
are your cup of tea, then it may be worth a look.
