A great way to have full control of your computer fans if you ran out fan headers or your motherboard BIOS doesn’t allow such great control, is with a fan controller. There are many types and today we have a very interesting one to show you. Enter the Reeven Polariz. Not only a very practical solution but also elegant.

We were curios about their naming scheme so everything might make sense if you have a general understanding of Greek and Roman mythology.

First about REEVEN :



REEVEN is a newly established international manufacturer of PC related products.

REEVEN’s product lines includes the best quality of advanced CPU coolers, such as Cooling Fans, Power Supply Units, PC Cases and many other items.

The target of their products is a wide range of audiences looking for products that will withstand the highest demand.

They run under the slogan “Don’t think. Feel it!”.


Regarding price, we were told a MSRP of 47 Euros.


Presentation and specification



The Polariz is a 3-channel fan controller that features a 30W power output which they claim should be enough for most fans on the market at this current time. Comes with three big knobs on the front (inspiration from cars) that each control one fan and display the relevant information such as temperature, speed and voltage.


Sounds very promising so let’s see it in action.


Packaging and content


A very simple box design with everything you need to know printed on all sides.



And extra info and specs on the sides.


The contents are well protected via a plastic foam.


Besides the fan controller itself, which is of metal and a has high quality feel, we have:


– 1x Instruction manual
– 3x Sleeved fan cable extensions
– 3x Sleeved temperature sensors
– 2x Stickers
– 4x Case screws




Hardware used:

Processor: Intel i7 2700k @ 3.5 GHz
CPU cooler: Stock Intel
Motherboard: MSI mITX B75IA-E33
RAM: 16 GB DDR3L Crucial Tactical VLP 1600 Mhz
SSD : Samsung 840 Pro 128 GB
Case: Fractal Design Core 1000
PSU: Corsair CX 600W 40A
Display: Samsung 32″ FHD TV LED 100 Hz – UE32F5000

– 1x 120 mm Noiseblocker B12-P – PWM – < 2000 RPM
– 1x 120 mm Corsair 12025 – 3 pin – < 1500 RPM
– 1x 80 mm Noiseblocker M8-P – PWM – < 2000 RPM

It’s very easy, just like any 5.25″ drive.
Plug in 1x SATA power connector and then up to 3 fans and respectively 3 sensors.
It even has alarms which can be set individually and a master switch to silent it completely.
Very nice, Reeven.



A quick test before the actual install we can see that all is good.


It has a perfectly balance light tone not too bright and not too dim.
We see 3 main readings: rpm, voltage and temperature (F or C)
It has a small delay until of 1-2 seconds until you get the actual reading from turning the nob.

And it fits flawlessly with a black case and looks so dam good !


After you set them at the desired position, it fluctuates a little but not to much from your set value.

And you can even turn all the fans OFF.





Usually products like these are a hit or miss because of their progressive nature and control capabilities.
But this one works very well.
It stands out with an excellent design, clean look and is all around well made.
So let’s rate it.

The good:

+ Excellent build quality and attention to details
+ Very easy installation
+ Excellent design
+ Good features

The bad:

– For the price we would have liked the see the option to select more colors for the indicator panel
– Only 3 fans to control and maybe should have included some splitters to add more fans, like 2 per channel
– That small delay to update the information but that is just being picky
