Reeven Polariz RFC-04 Fan Controller Review

Final Thoughts


In our testing, we tried various things. We connected a digital multimeter to the fans and were reading the voltages there and comparing them to what is shown on the LCD screens. We found the voltages to be spot on against the meters readings, but the supplied voltages do not have a standard amount of voltage drop if you will. It did not seem to matter the amount of load on the channel, or which voltage was used, sometimes the variance between the set voltage and the supplied voltage was as big as 0.3V at times. On the flip side of that, certain settings and on all channels, we found that there is a very little drop in the supplied voltage, and we were finding just 0.05V difference on our multimeter.


We also like that it takes two ticks of spin to make an adjustment, as just an accidental bump on them will not cause any fluctuation, you have work to change the voltage, it won't just spin freely and shut things off. We even daisy-chained a bunch of fans, in the order of ten to twelve, and still were unable to overdraw from the 30W channels. Then, of course, there is the slick LCD displays in the knobs and an aesthetically pleasing design that comes into consideration. If that weren't enough, not many controllers are closed up like the RFC-04 is, and for new users, it will keep them out of harm's way from shorting a component or touching bits that are screaming hot to the touch.



We also like the dip switches and the options they provide. Even though almost any software and comparisons done with temperatures are done with the Centigrade scale, the option to use Fahrenheit for those on this side of the pond is a nice addition. We also like that the ranges of the thermal alarm can be adjusted. It is a shame they cannot be set on a per-channel basis, but it is better to be safe than sorry. In this instance, use some software to see where your PC normally runs and set the switches according to those results. We also like the ability to be able to remove the jumper connected to the speaker. Of course, it would be handier to have it outside the chassis, but if it were to go off, the side panel is likely to be out of the way soon enough, so you can remove it then as you look for the issue. All in all, there is not one thing that surprised us about its operation, and the Reeven Polariz will make a great addition to any chassis. Unless you are looking for a completely smooth look to your build, why not use some of the largest and easiest to tune knobs in the industry?


We have seen similarly equipped fan controllers come and go in our time reviewing here, and to stand out against some of the better designs, we have seen in that time says a lot. If you are going to need fan control in a chassis and are looking for the best manual option out there, the RFC-04 is on the top of the list. This is a sexy and sleek fan controller is more than up to the task, with plenty of power on tap to power near 90W of fans in a chassis. Opting for white LEDs makes it easy to see in the dark, but slightly less visible when it's bright. If this is how far we have to dig to try and pick on the Reeven Polariz RFC-04, there is no way we can deny its worth when it is only $54 to obtain this fan controlling delight. Reeven shows they are always thinking of new ways to offer the basic things in our PC lives, and the Polariz is a great example of a new way to solve an old problem, and doing so with style and power at hand.

The Bottom Line: Reeven's Polariz RFC-04 is impressive to say the least! It is programmable, offers a unique design and styling, there is all the power one could need, and it is super affordable. For those who prefer manual fan controllers, this has to be in the top three options out there.
