Kingwin Fan Controller 4 Channel w/LED. Controls up to 4 Sets of PC Computer Fans, Independent Turn Knob Control, and Fits 3.5 Inch Drive Bay. Easy Setup, and Easy Control of Your Cooling Fans

Great product!

A great simple controller that allows you to control DC fans. As a few other have said, the build quality isn't the greatest, but at this price, I knew what I was paying for and it is definitely still a great product.

Yes, this item has a plastic housing, what happened to the all metal housings??? Yet the reason I am giving this 5 star is it fits perfectly in a Thermaltake Level 20GT hard drive cage!!! Actually I can put two of these in one cage and when I want to adjust the fan speed, just pull out the trays and adjust. I was first concerned about the thickness of this item and it being too large to fit the cages, but it does. I can see also why the screw holes would strip out easily and it only aligns with two screw holes in my thermaltake drive bays, but a tight fit and not moving. I am well happy with these controllers. These should fit in any the new model thermaltake dive bays or cages. GT or View models which I have.

Es un producto de muy buena calidad, facil de instalar, ya viene con sus paquete de tornillos, cumple con el control de velocidad de ventiladores reduciendo de un 100% a un 50% las rpm, no me decepciono, cumple con su cometido,las recomiendo ampliamente.

OK....I installed this last night and am SOMEWHAT happy with it BUT.....the variable speed will NOT lower your fans much lower than about 60-70% so you're not going to be able to really turn them down much at all, prob just enough to adjust the noise a bit but not near as much as I was hoping. BE VERY careful when tightening this into a 5.35" adapter tray if you don't have a 3.5" floppy compartment....this is plastic housing and pretty cheap and I BARELY tightened my first screw and stripped it out VERY easily so used a bigger screw to get it tight again. ALSO, if you have LED colored fans, the WILL dim also as you turn them down which is also a bummer....it's be nice to have the LED stay bright and still be able to turn them down like my case fan will if plugged into the sysfan connector on the motherboard but when plugged into this it gets dim as I turn it down, Also if you have software that controls your fans like some motherboard utilities have and some games can do it won't work as you're overriding these since they are plugged into this instead. All in all, I wish there was a way to simply have more case fan connections coming off the actual board instead or an adapter of some kind you could plug into the ONE case fan connector on the motherboard and have it create two-4 more sys fan plugs without sacrificing led brightness and better low end speeed like I get with my motherboard software (I c literally turn them down to like 10% and still have 100% brightness o the LED) but then I'm not sure if it'd power them all, but I don't see why not. But since most motherboards only have one sysfan maybe two connectors I went with this with hopes in achieving something that the motherboard (Gigabyte LGA 1150) software does and it technically does the trick but at the cost of not much change overall when turned down all the way (again at 60-70% lowest speed only) which is a bummer, I wanted about 20% and up variance but you won't get it....60% or so and higher is all this will do which isn't much really and then it REALLY dims your leds too so in hindsight I probably wouldn't have bought this and tried something else but for the money and the fact it's installed I think I'll leave as is for now until I find a better way since I'm not upgrading anytime soon to say water cooling where I wouldn't need the fans much...So if anyone knows a better way to have more sys fan connectors that come off the actual sysfan on the board I'm all ears....a moduar power supply with adapter cables worked to add more too but the mobo software wouldn't control all the fans without dimming either because they aren't seen unless plugged into the sysfan on the board so the LEDs and speed were topped out at max with no control but did of course work, just at full speed only. Kind of . bummer. I wanted to control two front fans, and 3 top fans with this which it DOES do, but the low speed isntvery low at all and then of course the LED lighting is variable too so the lower you go down the dimmer the LEDs.....not a huge issue but I like to show off my case and also wanted a much lower bottom end control....not just . 40-40% decrease but more like 20% and up option.... So for the dimming of the LEDs and the not so low fan speed-ability I dock a star for each.
