I bought the product because I wanted my fans to switch on and off at will. After 2 days the unit was there and I have installed it immediately - very easy! There are tidy cables and connectors supplied so I had not even more interesting products new. The colors are super front, the knobs feel super and for this price! I'm really impressed - the fully exceeded my expectations!
You can connect 3 fan. I personally, however, no CPU fan would connect simply because of risks that the processor its required air can not regulate itself.
