Adjust 108 Detailed Features
Final Thoughts and Conclusion

Fan Controller Final Thoughts

I like that this fan controller is made thick solid aluminum and metal all around, it feels strong and sturdy to the touch. The brushed aluminum doesn't show fingerprints as much as polished aluminum would either. The adjust 108 stands out from other fan controllers with its performance, simplistic and elegant appearance which is exactly what Fractal Design was setting out to achieve. I do feel that they overlooked the fact that some fans use Molex connectors and could have included 1 or 2 converters. Also one of the product features is supporting 36 watts per channel however when purchasing a fan or checking the fans currently installed in your computer, most fans don't say how many watts they are. Instead they state voltage and amperage ratings, a quick reference chart in the manual or side of the box would have been helpful to know that watts is simply voltage multiplied by the amperage.


Adjust 108 Conclusion

The Adjust 108 really pushes the limit with 6 case fans up to 36 watts per channel, this allows for plenty of room for adding additional case fans or looking into high powered fans with noise control. The fans audibly react instantly to being turned up and down which provides precise control and the LED changes colors above and below halfway point of the slider.

Instead of filling in every space of the box with ratings and specs, Fractal Design kept it simple. The fan controller looks professional and the brushed aluminum face is both elegant and presentable.

As far as the construction of this fan controller and the materials chosen to build it with, they fit together well. The frame does not bend under pressure during installation, and the front aluminum plate is generously thick. The power wires behind the board are spaced out enough to easily remove wires that are not in use which is beneficial those of us that appreciate tidy computer setups.

The sliders are spaced out into two sets of three, which makes it easy to control three sliders at once. The sliders are also made of a soft rubber which grip well to fingers and they glide smoothly.

Compared to other fan controllers the Adjust 108 offers higher wattage with no compromises for appearance and quality. Its a fairly new product and its on sale for $32.95 (Amazon), which is only a few dollars more then other brands that do not bring high wattage control or professional looks.

A fan controller is an essential computer component, the motherboard has a few fan plugs but its not going to give you six without a series of splitters, and they will not be easily adjustable on the fly like they are with the Adjust 108.

I find it very difficult to believe that this unit handles 36 watts per channel as the largest Capacitor is Chemical and not very big.. I would venture that 25 or less is more a realistic number but since most only put one or two fans per channel they can get away with since builds are getting smaller.. Its pretty and very effective and I am sure your Test was good.. I just don't see 36 watts coming from those tiny components.. I see smoke at 36 watts.

Your statement makes no sense as does your knowledge of electronics

The caps are only for filtering the input power to the controller and to each slider. The sliders themselves handle the resistance to decrease voltage, just like pots.

Now you are making sense, and if the only thing that is controlling the voltage to the fans is a voltage divider made up of a resistor and those sliders, then yes, if the slider or the resistor is not rated above the max current/watts, then the slider and or resistor will burn up. Most power sliders don?t go much above a few watts. As for the Caps, really don?t need them for just a simple voltage divider, it?s not like those fans have commentator?s which were very noisy with spikes.
