Computers these days because of fast speeds and people modding their cases use a lot of fans. The problem with using fans is that each one takes a Molex plug and you don’t have an infinite amount of them. There are a few things which you can do to help you with this problem, you can get a fanbus, rheobus, baybus, or similar fan control device. Today we are looking at a Dual Voltage 6 Port Baybus w/ Blue/Red LEDs which was provided by Sharka Corporation. If you don’t know what a baybus is don’t worry I’m going to go over what it does. A baybus is basically a fancy parallel circuit for the electricity. You are able to use one Molex connector to power 6 fans because when electricity is in parallel each device is getting the same amount of power as the first.
I really like the package of this baybus because it is a nice change to see something come in something other than a box. I like this tube because it is very protective of what is inside and is very compact. everything inside is also packaged well and the baybus is protected with bubble wrap.
The package includes the Dual Voltage 6 Port Baybus, 6 LED clips, acrylic drilling template, Molex Y-splitter, and instructions. The baybus comes with bubble wrap around it so that it is protected during shipping. The drilling template is nice because it has adhesive tape on the back of it so that you can stick it onto the faceplate that you are going to drill. The instructions are really good and easy to understand, I really like when products come with instructions no matter how simple the product may be because not necessarily everyone is going to know how to use it. The LED clips are provided to make the unit look better when you are done and the Molex Y-splitter is nice because it will save you that Molex.
The top of the unit is really clean in design and looks really professional, each switch is labeled with what number it is. The LEDs have a brace around them so they are not just bare leads which could be bent. You can also see that at the top there is a pot for each switch which will be looked at more next and there are all the other electrical components on the PCB such as the mosfets and resistors. The side view of this unit shows you the DPDT (dual position dual throw) switches, each switch has 2 nuts and 2 washers on it.
The front of the baybus has Pots located at top of unit facing upward, there is one for each switch which can be used to adjust the low voltage level. You can Adjust it from 7-9v this is a good thing because the higher voltage may be necessary for fans that require more voltage to operate at lower voltages such as Sunons because they wont run at 7v. All you need to do if you want to increase the voltage is take a screwdriver and turn it up. The back of the unit has a really clean layout from the traces, to the solder points, to the configuration. The screw terminals for where you will connect your wires for your fans is really awesome, each terminal is labeled with red and black and for which switch it will be on. I really like this because it is clearly labeled and takes any guess work out. I also really like that the Molex plug is facing back rather than to the side. This makes plugging and unplugging really easy.
