The fan controller arrived  in a really good looking and stylish grey carton box with lots of information about the product on it. In fact the only place with some technical details is the box. First thing I saw is that this model can be bought in two colours – black and white.

All of the technical details are on the side panel of the box, while on the back are shown the warranty details.

First thing I saw after opening the box was the product manual which is very important, and beneath it there were two compartments, one holding the fan controller and the other holding all additional components.

So it is about time to check the fan controller itself.

The fan controller is made of plastic in black with six small displays corresponding to each channel and six FAN rpm control knobs controlling the fans which are hidden behind the front panel.

All of them are push-pull type and when they are released they look like this:

Behind the front panel we can see this:

Reeven SIX Eyes is made of two separate PCBs with connection between them. The first one is holding the displays and is in vertical position, while the second one is holding the connectors which are:

1. Six 3 pin connectors for attaching the fans
2. One 4 pin floppy disk drive connector for powering the fan controller
3. The next series of pins is made for attaching the thermal sensors
4. Jumper switch for choosing how the temperature will be shown on the display – C◦ or F◦
5. First DIP switch is for setting the Alarm features. More details how to do it is written in the manual.
6. Second DIP switch for choosing the backlight colour. More details how to do it is written in the manual.
7. Last jumper is to choose if there should be alarm signal if any of the fans stops. The alarm is really loud so its impossible not to hear it.

Every one of the channels is supplied with a transistor with very small heatsinks which gets a bit hot after some time of using the fan controller, especially when there are 2 fans attached.

Apart from good visual appearance and probably good performance (I will check that a bit later), Reeven SIX Eyes fan controller comes with really nice package contents:

1. Six really long 3 pin cable extenders, so every fan in the case can be attached to the fan controller
2. Six thermal sensors, again with very long cables
3. Four pin to floppy disk drive cables for powering the fan controller
4. Four metal screws for mounting the fan controller
5. Eight stickers and 1 advertising sticker

It was about time to assemble the bench and test how Reeven SIX Eyes fan controller will performs. The test will be conducted with the help of these additional parts:

1. Cable splitter with option for measuring the voltage.

2. The fans I am going to use for testing this cooler are:

1. Two Cooler Master Excalibur with max current at full load 0.45A and 6W max power consumption
2. Two Reeven Coldwing 120mm Performance (RM1225S20B) with max current at full load 0.52A and 6.24W max power consumption

So far the review is just words and pictures. I think its about time to see something a bit more interesting:

I guess its time for some personal thoughts…

1. Performance – After I finished the tests I can say Reeven SIX Eyes provides stable and reliable work. It is strange that even without attached fans the controller cannot reach 12V at max but I also noticed that the voltage drops are in a small range with one or two fans attached to the first channel. Apart from that when one or two fans are attached on the first channel we see very small voltage drops on the other channels which is really good because even on max load on first channel the others keep running stable. I’ve also noticed that with max load (1A) at first channel the heatsink gets warm and after some time even hot, but I didn’t have any problems.
2. Visual – well I think Reeven SIX Eyes can fit in any case with 5.25″ bay and can provide great appearance effect. The model is clean and stylish and this is boosted with the push-pull fan control knobs. Apart from that, those 6 small displays provide all of the information needed for regular use (fan speed and temperature when the thermal sensors are installed).

After I conducted the tests I can proudly say that this fan controller can handle up to 6 very powerful fans, which are more than enough to cool every modern system. Well yes, there is some extra power that can be used to attach more than 6 fans using cable splitters but at max load this could cause problems if the controller works like this for a long time because the transistors heatsinks are a bit small.

I think Reeven SIX Eyes fan deserves the following reward:

I thank Reeven for the samples!
