Simple and effective
Who needs fancy lcd screens with temperature and rpm readouts? That's all fluff. This fan controller is very simple and effective.Pros: Very simple and easy, slides in any CD/DVD drive bay, looks good, does as advertised.Cons: Each fan adds about a foot and a half of wires. (Hope you're good at wire management)The plastic feels cheap and the whole thing wiggles very slightly when it's installed.The minimum setting for each fan is 40%. So you can make your fans quiet but not that quiet.Summary: I only have it controlling 5 case fans. But it does it well. Turing my fans up actually keeps my graphics card about 3°C cooler under load on average. Despite the cons I listed I would buy this again and would recommend this to anyone looking for a fan controller and nothing else.

I did a huge amount of research prior to purchasing this fan controller. I found Linus Tech Tips from YouTube as a great resource for hardware reviews. I installed this unit into a Corsair Air 540 case and its controlling 6 fans in total. Two Noctua NF-F12 fans mounted to a Corsair H105 rad in Pull configuration, a rear Corsair AF140 Quiet Edition LED Blue, and 3 Corsair 120AF Quiet Edition Blue LED fans in the front for intake. It does exactly what I wanted it to do with simple flair and style. It matched perfectly with the Air 540 case, and the air 540 has vertical 5.25 bays up front and it works perfectly well vertical. I love it.

Controlling the fans is simple and easy and the sliders have a great solid feel to them even though they are gloss plastic. The entire controller casing is plastic with the controller circuit board being more ridged and metal. The entire controller comes with 2 molex power connectors to power this device and all cables are nicely labeled and per-connected.

If you use LED based case fans like I did the controller will control the LED power level slightly. I love that as I drop the power to case fans to minimum the Blue LED fades only slightly, and its a nice touch on the Corsair Blue LED fans.

Using the controller is simple and easy and also fits well into my tool less drive bay and is very secure. The LED feature is bright but not over powering which is very nice.

The controller has a matte finish which will match any matte finish cases, while the sliders are gloss black. It stands out and is a nice look but just be aware that the controller is more matte in finish.

Overall solid product, came well packaged, and had everything needed for install. Recommended over more expensive products.

Very cool fan controller. It supports up to 6 fans (more if you have a fan splitter) and controls with sliders. I like the sliders, they have a bit of resistance to them, as in they don't move like butter. The range is 40% to 100%, and it speeds up and slows down the fans gradually, instead of an instant spike/drop in speed.

The front LEDs are nice, the blue looks perfect with the rest of my build. It also has a very nice white, red, green, and orange, as well as having an off setting (you wold hold the LED button down for a few seconds). The LED button isn't the most quick to respond thing, I have to hold it for a tiny second for it to switch, but that's no issue.

The cables are very long, they could easily run through a full sized case, probably with a bit extra. All the plugs for the fans are labeled with the number they correspond to on the front. The plugs are only 2-pin, but can fit 4-pin PWM fans. The controller adjusts power, not straight RPM, so if you have LED fans, you can notice they get slightly dimmer as you turn the speeds down.

I would recommend this to anyone who wants to keep their computer quiet, and adjust speeds on-the-fly.

And I would LOVE IT if it weren't for the fact that I didn't have to do some minor repairs on one of the sliders, #1 ironically enough, prior to installing it. Luckily I had a tube of Extra Thick BSI Maxi-Cure cyanoacrylate super glue on hand so the repair was pretty instantenous, but still a shame to have dealt with regarding the actual quality of the product right out of the box. If you want to avoid this problem in case of a return, please inspect the sliders by moving them up and down and feel for any of the sliders acting more loose than the others, that's what I discovered and the sliders themselves are easy to take out to check if you have a broken one like I did.

Other than that one issue this thing is great. Probably my most favorite component on my PC to date as I'd already fit the maximum amount of fans on my case but did not want to stay dedicated to software controlled fan support and went with this analog approach. The dream of running a dead silent computer is much more effective with this controller as the voltage can reduce the speeds down as low as 40%, and then crank them up all the way to 100% to turn your PC into a turbine of cooling efficiency. I actually wish I could have had a 25%, or even a 30% reduction as its lowest RPM setting but this is fine.

The beauty behind this controller is its simplicity. While a touchscreen LED is cool, it's too much for me. There are other fan controllers with knobs and sliders but oddly enough they run around the same price range while having access to less sliders/knobs on them. Outside of that range and you get a bunch of other features on them I personally wasn't looking for or desired. I actually am not utilizing all 6 sliders on the controller, leaving #'s 4 and 5 unused, but it's nice knowing I have the option to them whenever I want. Also, due to the nature of my case, the controller sits vertically inside its 5.25 bay as opposed to the typical horizontal position, meaning I use the sliders left and right as opposed to up and down. This is actually ideal for me because now I know that gravity won't come in as a factor in affecting the sliders moving up and down should I have to readjust the sliders and pretty much wear them down from however much use I utilize them. I'm not too sure on the actual quality or longevity of this product's sliders since I just recently installed this thing and started using it but I imagine it has to hold up pretty well considering the rave reviews this thing has prior to my own observations.

LED functions are great too. You have 5 colors to choose from, White, Blue, Red, Green and Orange. So if you have colors associated with them to complement your build, know that you have that option. You can also turn the LEDs off completely if need be by holding down the button you press for choosing the LED color for about 5 seconds. You also hold it down for 5 seconds to turn them back on if need be.

A fair bit of warning before getting started on this thing: there is a menagerie of wires to deal with. Unleash them from their twist tie confinements and you have quite a bit of length to deal with so plan accordingly on the lengths you actually need and then reuse the twist ties to tidy up. Having some cable ties on hand is not a bad idea either and probably preferred if you have a fixed idea on how much length you'll actually need to use from this controller, otherwise you will virtually have a spaghetti's worth of wires to deal with, making the process pretty confusing even though the fan adapters themselves are all tagged with their associated sliders, Fan01, Fan02, etc., etc. Deal with that and you're pretty much set with a simple, effective fan controller. The voltage regulation also affects certain fans with LEDs on them, which is cool to watch the lights dim brighter and brighter whenever I crank up the speed and then see them dim back down to a subtle glow when I put them back to the lowest setting. Makes the whole process feel more interactive, very cool.

There really isn't much else that needs to be said about this controller. Though I am personally disheartened that I got a controller that I had to do repairs on myself, aside from that this thing is pretty solid so far. I enjoy the fact that now I don't have to have a constant whisper of air rushing through my case until I really need it, such as in the case of overclocking or a heavy dose of gaming, where then I can just move the sliders to their respective speeds. Hell, thanks to this controller, the loudest thing in my room now is an external harddrive that sits next to my computer which I got years ago and can be heard from its constant spinning while active.

Personally, I would buy this fan controller again if and when I build another PC with fan regulation, but I hope the next one I get doesn't come with the curious quality I had to deal with and hope no one else has had to deal with either. Better luck next time I guess, but this thing is definitely a must buy for any person looking for an effective fan regulation solution.

5.0 out of 5 stars Nice quality option for fan control

When I first built my desktop I tried to find the best performing and best quality parts I could find. I originally used the Scythe Kazemaster fan controller (model KM01-BK). It gave full temperature readouts & fan speed adjustments for up to four case fans.

I don't use my desktop much (let alone adjust my fans much) and it worked fine for a while then one of the knobs stopped working unless it was wiggled and then one day I had internet radio playing and I left the room and the controller died cutting off all my fans and almost overheating my entire system. The same Scythe model seems to be sold under a different name lately.

After researching various controllers this one looked to be solid quality and it fits nicely in a case that has a door that covers it. Other ones used knobs that stuck out too far, this one uses a graphic equalizer style slide band. It also has a button that adjusts the color of the LED lighting so it can match your case lighting (blue, red, etc). It was packaged quite well, installed & fit nicely and seems to do the job well.

Controls my watercooling pump perfectly. I have a Laing DDC 3.25 and that thing whines like there's no tomorrow at 4650rpm but is quiet at 2700. The controller starts it at full rpm for a few seconds at the boot up and then slowly bring down the rpm back to the desired speed. It's a great feature to ensure your pump or fan have enough power to start.

I have used several of these excellent fan / pump controllers over the last couple of years, and find them easy to install, solidly built, and super reliable. Each of the 6 control channels can supply up to 30W, so is plenty powerful enough to be used to control custom water cooling pumps for ultimate tuneability. Alternatively, you can buy fan cable splitter cables and run 2 fans from each channel, giving a potential for controlling up to 12 system fans. The slider controls are nicely weighted, and move smoothly, giving fine control over connected equipment, and to top it all off, there is a choice of LED display colour via a small unobtrusive button on the left side of the front panel. I have tried many different controllers over the last few years, and this is my personal favourite, not as flash as the many touch screen rivals, but soo much nicer to use.

I purchased this to quiet down my system since the motherboard did not support over 2 fans. I currently have 5 in the system right now and has it made a difference to the sound! Nice and quiet - easy to setup and mount as well.

Pros:
Control up to 6 fans individually
Takes up useless 5.25" bay
LEDs to match the colour of your system (in my case red)
Super easy and simple to use - the higher the slider the faster the fan and the more noise it makes
Girlfriend doesn't complain about the sound of my computer anymore (but Blue Cherry MX keys are next so...)

Cons:
White LED doesn't exactly match my case (Corsair Spec M2)
Extra wiring (for 6 fans) that you have to manage

Product arrived quickly which was nice considering I ordered it the day before assembling my new computer. While I bought this mainly for aesthetics, I was pleasantly surprised by the device. So far works great. It fits in the front bay perfectly and, contrary to what I originally thought when buying, it doesn't look cheap. Extremely easy to install and connect the fan header cables. The fan adjustment itself works great which is nice when you want to reduce fan noise while the system isn't under any stress. LEDs look nice and are changeable by the tough of a button on the device. For the price, this product is great.

Absolutely love this product. Looks great on any build because of the custom LED settings and it's a great way to ensure good airflow, less dust intake, and a quiet rig. It can easily handle multiple fans per channel with a Y-splitter, and I currently have 8 fans running off this controller without issue. The 30 watts per channel really offers up some nice flexibility. It's a fairly inexpensive part that can drastically improve the quality of any rig.
