"What is a Dual Voltage baybus you ask? Well it's a centralized connection point for your fans to attach to and the unit will let you control the voltage the fans get. 12V is the normal voltage if you just plugged your fan directly to the psu. but this unit lets you step it down to only 7-9v thru a toggle switch and the mechanics of the units design. The main reason anyone would want to do such a thing is NOISE! We all hate noise! Even the loudest fans can be tamed remarkably well by simply giving them less voltage which will in turn cause them to run slower and produce less noise. Of course the airflow will be effected, but most of us only really need that top speed when we're gaming or stressing our systems in other ways. If your PC is sitting idle, why not be able to tune it down a bit? This unit is the no-nonsense answer right here. This unit works in much the same way as the hugely popular PCMods Baybus does, but it certainly steps it up a couple notches and also improves on the design theory making it easier to get to the wire screw-downs. I usually wait till the end of the review to spill the beans....but I gotta tell ya right now.....if you're looking to buy, rather than make a baybus .....then this is THE baybus to own!! Ready to see more?.....Follow me....."
