4-Channel Cooling Fan Variable Speed Controller for PC

Pros: Easy to install
Very Light
Provides more speed and light than motherboard fan power slots
Plug & Play, only 1 normal PSU power plug to get 4 fans running at max

Cons: Just a bit bit pricey
3½ ! My case don't have those ones anymore, could be 5¼, but I managed to install it anyways.

Other: Useful, small, great blue led lights in 4 fan controller wich makes my case look even better.

Pros: - Easy install
- 1 PSU power to power up all 4 fans
- Looks nice
- Easy to understand and easy to use
- Works like it supposed to do

Cons: - None big cons realy, does what it is designed for.
- The knobs could be better thought, some of them are easy to turn, someone is harder to turn

Other: - Realy nice and where i live cheap product, realy worth the money
- My pc is much more silent now thanks to this product, go and buy!

Pros: Easy to install, understand and easy to use. Led indication makes my case look even better.
With this product one PSU can power up 4 fans.

Cons: Maybe overpriced of a little bit.
Build quality is not good. Received item was broken,- knobs wasn't fixed in case, because one of bolts that hold panel was missing. Fan cables aren't removable because they fixed in case.
Plastic is cheap and could be a better.

Other: Useful, small, good product, but have many cons.

Pros: The nice thing! I've connected 3 of 120-mm Scythe and my Zalman 9500 CPU cooler to it. The noise is very small now, it's much better than PWM control of motherboard. And if it's too warm in my house I always can increase speeds of my coolers.
The build quality is simple but very good, it's stands nice in 3.5" hole of my computer case.
And the price is lower than price of the most simple speed controllers I've seen in our shops!

Cons: none

Other: Must have!

Pros: This device can control up to 4 fans and It can handle up to .65Amps per channel and fans of 12v (7.5W)
the total power it can supply is 30W
it has very bright blue led (for some people might be a con)

Cons: the knobs (pots) have a lot of death space and it doesnt totally stop the fans.
with big fans the It can get a little bit warm
It doesnt work with PWM it is made with a transistor as a voltage follower so It consumpts the same energy even if is not at full speed.

Other: I would preffer red leds so Im planing to change them.

Pros: Works well let you connect up to 4 fans connecting 1 molex(it has 1 female molex an a male so you are not "losing" a molex),you can use 3 or 4 pin fans .
Looks good in black case

Cons: Some people might not like the blue lights, when you are using it you cant monitor the rpm of the fans.
There are no indications of wich knob controls wich fan.

Other: Considering it can control 4 fans and the price(branded cost 2 or 3 times more) its worth it.
The delivery was relatively fast like 11 or 12 days.
Came well packaged in good shape.

Pros: The quality of the unit is surprisingly good Most units like this sell for 3 or 4 times the price. Sure, the quality might be a little higher, but once it's in your case you won't notice. The lights are quite bright and pretty, but they are blue! So if your case glows red, it won't fit so well with your color scheme. The device does not provide any monitoring or any automatic control, so wouldn't be very good for a CPU fan or main case fan. But, if your case has a lot of fans in it, it's perfectly capable of controlling those!

Cons: The device does seem like it can get a little warm with some larger fans running on higher speeds through it. Perhaps a little cooling fan inside of it could fix this... The heat from it shouldn't be a problem for the most part, just a slight concern for me personally. Some may consider the bright blue lights to be a con. If your case is lit up with blue lights, it'll look really cool. If not, sorry..

Other: Good little fan control!

Pros: Allows you to control up to four fans using only one molex connector. The four connectors are 4-pin, so can connect both 3-pin and 4-pin fans. The connectors are labelled with a sticker so you can tell which plug for which dial i.e. FAN1 is controlled by the first dial. Nice, bright blue LED. Build quality is quite good, no problems so far.

Cons: Paid USD$9.90 for it just a month ago, now USD$1.70 cheaper at USD$8.20.
LED may be too bright for some people.
Needs a 3.5" slot, which newer cases usually do not have.
Cannot turn off fan completely, and difficult to gauge how much fan is slowed by turning the dial.

Other: If you don't want to buy fan splitter cables, this is a good alternative. Allows you to have many fans in your case.

Pros: - 4 controllers for a low price
- Good fit in a 3.5 bay

Cons: - Not standards screws for mounting. Needs to use those wich are coming in the package.
- LED light are on all four controllers as soon as its powered up. I thought that leds in some way indicated if fan was working(and hoped the brightness was connected to how fast fan was spinning)
- Very plastic

Other: Its ok if you need a controller for your fans. However don't expect anything more than a controller for 4 fans and a cable splitter...

Pros: Great looking works great good construction simple to install and use

Cons: I think it can have a switch to turn off the leds Its a bit bigger than my thermaltake v3 3 1/2 bay cables are too long , for an atx case, are a lot of cables uses special screws. its only a blue version.... it doesnt stop the fans, only set it to a very slow speed, but never stops.

Other: if you need to manage more fans than your motherboard can controll, its a good cheap option
