Sunbeamtech Rheosmart 6 Fan Controller Review

Price: $ TBD


Sunbeamtech is a relatively unknown company in North America, and their name holds more weight down below and overseas than it does here. Sunbeamtech is a multifaceted manufacturer, as they make cases, heatsinks, and even power supplies, but, what Sunbeamtech makes the most of, is computer accessories. Things like cold cathodes, fans, enclosures, and mice are more Sunbeamtech's forté. Recently, Sunbeamtech released a new line of fan controllers, called Rheosmart. The Rheosmart series is composed of several basic fan controllers, the Rheosmart 3/6/PCI. Both the Rheosmart 3 and 6 are 5.25" internal bay solutions that offer fan control either automatically via motherboard sensors, or manually via rheostats. Today I'll be taking a closer look at Sunbeamtech's Rheosmart 6.

Closer Look:

The box of the Rheosmart 6 is nice and small, which forces the text and photos to be a little smaller and closer together than if they were on a larger box. Combined with the warm shades of blue all around, it has a cozy, inviting feel just emanating from it. On the front we're treated to a scaled photo of the controller surrounded by a glowing, white halo. There are also what appear to be sound waves emanating from a small drawing of a motherboard to the Rheosmart, and sound waves emanating from it to six small drawings of fans overhead. What does this mean? Am I being told the Rheosmart 6 will make my fans noisy? Will the Rheosmart 6 utilize infrared wireless to power my case fans? Perhaps another side of the box will clarify this curious illustration? Moving on, on the left side are little icons that represent the various features of the Rheosmart 6, including, but not limited to:

  • PWM Control
  • 6 Channels
  • Max Output 30w Per Channel

So, now I know that the Rheosmart 6 can control up to six fans and can provide 30w of power to each one. An impressive amount of power, considering this unit obtains power from a single, standard sized 4-pin Molex connection. Unfortunately, due to a lack of six, high-powered fans, I won't be able to test this. Might it also be that PWM control explains the those silly waves?





Finally, that unusual drawing on the front is explained! Essentially, what the drawing was showing is that the Rheosmart 6 can automatically control the fans connected to it by the information that the temperature sensors on the motherboard it's plugged into gives it. That means that the fan speed will be adjusted according to the temperature that the sensor provides. Sunbeamtech refers to this feature as 'Smart Cooling'. Also back here are the specifications in a nice and tidy table, and compliance logos.

The short sides of the box are void of any additional information. Only logos and names here.


And inside the Rheosmart's box is...another box! A cursory glance shows us a manual, some cables, and the Rheosmart 6 itself, snugly packed around with firm foam. Let's take a closer look and see what all comes with the Rheosmart 6.
