6 Fan Controller Roundup (Second Half)

Page: 1/4
Manufacturer: Noise Isolator
Product Name: 6port (Baybus)

Thanks to

For Providing Us With This FINE Product to Review

The last full-sized baybus in the fan controller roundup is Noise Isolator's 6port dual voltage Baybus. This baybus was supplied by a newly created mod store called AutoDeletePro centered out of Canada. I am not sure what the name means or am I sure what it has to do with computers, but they offered us this product for review at the perfect time while I was in the middle of writing the roundup. When they first showed me a picture of this controller on their site, I wasn't too surprised to see that it was the typical style of a dual voltage fan controller. Before I even pulled this product from it's silver and black box, I figured I might check out product specs before testing. I was surprised to see that this controller only held 6watts per channel. Either way, I was prepared to test this one to the limit with 92mm Vantec Tornado fans! Another thing I noticed, worth mentioning were the led colors. On a high voltage (12v) setting, the LED above each switch appears red, but on a low voltage (7-9v) setting, the LED appears green. Red/Green are typical LED colors on these dual voltage baybus'. The only company that has released a baybus with different colored LEDs is which make theirs Red and Blue (only the ones which they design and manufacturer personally).

The color options with this controller are rather simple, original aluminum or a sleek black anodized aluminum faceplate. Both colors are available on AutoDeletePro, but in this review we will be taking a look at the BLACK anodized version. Upon opening the silver and black box which the controller was in, I pulled out the controller, a weird looking cable with male 3-pin connectors at one end and stripped ends at the other and a set of printed instructions. Let us first take a close look at the controller. The controller itself comes preinstalled into an aluminum faceplate. On the front of the black faceplate are six visible 3-position switches as well as six visible dual-colored LEDs. Each position on the switches control voltage output on that port differently. For example, the switch in the middle position cuts voltage output off (turning the fan off). When the switch is switched to the bottom position, the LED above that switch turns green and voltage output is set on low which starts the fans spinning slowly. When the switch is in its most upright position, the led above that switch is turned to red and voltage output is changed to 12volts which essentially powers the fan on that specified port at full RPM. One thing that I kind of laughed at when I took a look at these switches is the fact that AutoDeletePro installed the faceplate on these slightly wrong. On the fanbus, there is a washer which has a small bent-up tab which is meant to go between the faceplate and the controller instead of between the nut and the faceplate on the outside of the controller. This is nothing to get our panties up in a bunch about however, a simple fix would be unscrewing the nut screwed to each of the switches and pulling the controller off to put that washer on the INSIDE of the faceplate. Keep in mind, having it stay as AutoDeletePro has installed it does NOT affect performance of the product whatsoever. As you should know by now, any controller which is anodized is put through a little scratch test by me. I pulled out a penny, and with light pressure on the black faceplate, I was able to see a small scratch. As I applied a little more pressure, the faceplate was easily scratched. Although your baybus should not take much abuse as long as it is properly installed into the 5.25" bay, we conduct these kinds of tests to keep you aware of ALL aspects of the product. After checking out the circuitry on the rear of the controller, I wasn't able to really see anything that stood out, except the HUGE green wiring terminal located in the top left of the PCB. Keep in mind that EACH FAN consumes two holes in the wiring terminal, thus, 12 holes make the terminal quite hefty! You can forget about getting confused on installation however, because printed above each hole in the terminal is a port # (1-6) along with the wire color (black or red). Power is provided to the unit through the molex connector located on the left of the PCB. The last thing which I noticed on this controller is that above each switch, located on the TOP of the controller are yellow voltage regulators for the controller's SLOW setting. By default, this controller outputs around 7volts of electricity, but if you plan to run higher rpm fans like Sunon and Vantec Tornados, you will require at least 9volts of electricity before the fan even starts to spin. For this reason, Noise Isolator has placed these yellow "pots" on the top of each port to allow you to control how much voltage is being output on the low setting, between 7volts and 9volts. If your fans already spin on the default pot setting, you may opt to leave it where it is or spin the fans up a bit more to get a couple extra RPM on low setting.


Next, included with the device was a strange set of cables all stuck together like an IDE ribbon cable. Each wire alternated between red and black. The total length of the entire clump of wires is about 7.5" long. On one end of the clump, each of the twelve wires are striped and twisted together which will later be used during installation to screw into each of the twelve holes in the terminal block (on the rear of the controller). On the other end of the clump are six, 3-pin fan connectors. I was afraid that if I used this controller, I would be forced to cut the molex connectors off of each of my precious tornados and screw the stripped wire into the terminal, but AutoDeletePro has made it so all I will need are six 3-pin to molex connectors. These were obtained from the other controllers in the roundup, but can be purchased online as well. When I finally got a chance to glance at the instructions with this device, once again I had a good laugh. Although the instructions were a simple and effective, I got a little confused when they expected the user to plug the controller in to the molex on your power supply THEN screw it into the empty 5.25" bay, creating a HIGH risk of shock. The last thing noticed on the bottom of the instructions in bold lettering read, "NOTE: Please be sure not to use any device over 6W per port with the fan controller." In this review, we will be bypassing this "note," but it is advised to follow any instructions at all times for the normal everyday PC user.


Installation with the controller was a breeze! After taking a couple of minutes to screw each of the twelve stripped wires into the terminal block on the rear of the baybus, I simply screwed it into my empty 5.25" bay in our tester case, hooked up each of the six 92mm Vantec Tornado fans and then finished off installation with molex power. Before I go any further, be advised that you WILL need a small flathead screwdriver for installation into the rear terminal - this definitely delayed me while I searched my workshop frantically for one. Once I powered on the computer, I immediately flipped the fans on to low voltage only to find that *gasp* they didn't spin! So, I turned the computer off, tweaked the yellow pot switches located on the top of the controller and after reinstallation, I turned the computer back on. I flipped the six 92mm Tornados back onto low voltage and was surprised to see how LOW each of the fans was spinning! I did notice however, that after a few minutes, the controller was putting off small amounts of heat, but not enough to concern me. Next, I flipped all six into HIGH voltage and was surprised to see that for some strange reason, the controller cooled off! I proceeded to take an average of the voltage readings which can be found in the table below.

Vantec 92mm Tornado (4800rpm)

Highest Setting

Lowest Setting

4750 RPM

2100 RPM

As you can see, these results were way different than I expected! After reading that each port was only supposed to hold 6W per port, we filled each port with a fan that required up to 12.5watts and ran the baybus for 24hours without anything being burned, melted or broken. I am even surprised to report that the controller was not even HOT, but did give off a somewhat warm feeling. On the lowest voltage of this controller, I was not disappointed at all to see that the RPM was comparably lower than that of the previously reviewed Vantec Controllers, but still did not show lower than the RPM readings of the Sunbeam Rheobus. The RPM readings were also exceptionally well. They were just where I expected them to be, averaging only 50rpm below their full capabilities. Although I was definitely disappointed to see that the baybus did not include instructions on installing this product to your own faceplate, it can easily be done by using the pre-installed faceplate as a drill template. Even though we were able to push this controller to the limit by running fans which required up to TWICE what the company claimed could be supplied, I would not attempt to stress the controller for permanent use which would require slower fans than any Tornado available to this date. Overall, this controller did perform great with the test which we put it through. I was also glad to see that someone had finally made installation of multiple fans easy WITHOUT cutting the connectors off of those expensive fans! I would not have a problem recommending this controller to anyone who does not expect to run Vantec or Sunon brand fans due to the electrical demands. If you are interested in this product, pick one up for about $36.00 USD which is a bit on the high side, considering they are not available with more than 6W per channel.
