For those who have Big Towers I see it pale. Most people get Mid cases, this one has 6 roll overs, in other words you can put 6 120s or 6 140s. There is a patent to feel a little, you can put in each cable where you connect the fans from a switcher. For example, if you place 1 switcher this cable will allow you to connect directly 2 fans. Because this in Electronics we call it a branch. In other words, if you buy 6 switchers, for example, you can connect 12 fans of your choice, without having a problem for short circuit or any technical error. The central cable that connects to the motherboard takes power from 12v to 24v, in other words it doesn't hesitate and happens to have bought 2 of these, I was very lucky because they have run out from most sites, I highly recommend it and don't look at the fans you buy to have lights and frills, look at each fan you look at before you buy it in their characteristics, the cfm or pressure in other words that the fan pushes inwards in your case to have a large number to do proper cooling and proper Air flood, the cfm must be above 60 cfm for proper cooling, there are also fans with over 100 cfm, I have 4 kids and my case is 3 meters away from me so I don't hear the noise, but it's worth it my motherboard is always at 30 degrees in games and if it does nothing let's say it's at 20 degrees.

First impressions:
1) It does its job very well. If you're not using the computer and just downloading a movie or playing a game while reading, you can turn them off completely. If you're watching a movie and playing a mini game, you can turn them on a little. If you're playing games, you can put them on maximum. Whatever you want.
2) The LEDs turn off when you have them turned off.
3) It has very long cables, so you don't have to worry about how the fans will reach the 5.25" bay.
4) These cables are, of course, very colorful... (red, yellow, black)
5) The power supply is a passthrough molex and the fans can be either 3-pin or 4-pin.
6) The price is okay.
7) You can connect up to 6 fans in parallel, so they all have a 12V voltage and each channel can have up to approximately 1.7A current.
8) 1 year warranty, this worries me.
9) The LEDs are bright, so if you have the PC in your line of sight, it might be annoying.

Excellent if one considers the price and capacity for 6 fans. Quality metal construction and compatibility with 3-pin and 4-pin. Ideal ability to deactivate any fans that are not needed. It fits in a PC with a port if you screw it in a little further.

Very good construction, the whole chassis is metallic and the front is aluminum. Quite good sensitivity for voltage adjustment and overall it looks more expensive than it actually is. The huge downside is that the LEDs are too bright. For example, in a dark room with only 4 of them turned on, you can see them perfectly as if it were a small light turned on.

I don't know much about these things, but after a lot of research and reviews among many fan controllers, I ended up with this one. It seems to be of good quality and you can connect up to 2 fans with a split cable on each channel, as each channel supports up to 20W, so with the 6 channels it automatically has, it's more than enough for a case, you can connect up to 12 fans if you want. As for its price, I can say that it's perfect for anyone who doesn't have many fan ports on their motherboard. I happened to have a slightly stiff second knob, but it's okay, I just happened to get a slightly defective one, but it doesn't have any issues, it works fine.

I have it for 6-7 months! Quite good, it saved me because I changed the case and it has more than 5 fans, while my motherboard had only 1 port. Very good, the only small problem I noticed is that sometimes the cable doesn't make good contact and the LED doesn't light up, but the fan works perfectly fine!

Good product. Today I received it and set it up. Very useful for adjusting fan speeds. Recommended.
