Pros: cheap
can turn off fans completely

Cons: 2 lights are flickering on and off annoyingly, most of the fan connections are hard to push on and some of the included cables are deformed and near impossible to use

Other Thoughts: for the price i'm pretty happy, wish they had a model with no lights at all as that seems to be the main complaints from most and they serve no great purpose

Pros: Well it handles my 5400 RPM 240CFM super fan. and it works so far..

Looks cool for the price.

Cons: Power connector plastic pins pushed right off when i was connecting it and made it scary to use for a minute there. Still might return it if they will take it cause i wasnt forceful one bit with it and the plastic would not go back in without causing more damage.

Not knocking this product cause im sure most people have good use from it but i would sprint for a slightly higher end model if you dont want to chance electrical fires or shortage.

Other Thoughts: Could have bigger heat sinks but still handles my 3.7 amp super fan so it must be somewhat conducive to its lower cost.

Buy one if your just looking for easy fan control

Pros: well, when it worked it did the job,

Cons: 1 channel stopped working and threw sparks

Pros: 1 fan controller is working, fortunately that's all i need so i don't need to bother with RMA

Cons: 2 fan controllers don't work, and the other requires not fully connecting the 3 pin header in order to work. no idea why

Pros: Cheap. Four 20W channels are nice.

Cons: Does not fit in my Corsair 800D bays. Poor quality craftsmanship and engineering.

Pros: I am so impressed with this product!!
The knobs/Pots feel really nice and are dampened
The leds are NOT too bright, perfect for me :)
It has a range of 0v-12v
Can turn of a channel and "clicks" off
Looks great, and can controll Cold cathodes
20W per channel is great
Does not get hot at all even when under heavy load.

Cons: NONE!! they leds are NOT too bright people. and if they are too bright fo you, you can replace them because they are only pushed into a socket, or you can puch them back into the frame.

Other Thoughts: I am not using it for fans, but i did test wit with many fans. i am using it to dim 4 cold cathode Kits. there are now a total of 8 cold cathodes in my case, and i can dim them or turn them off if needed. i LOVE this product!

Pros: I love nearly everything about this controller. It does exactly what it says it will do, and can control four fans at once. Works perfectly and even changes the color of the led when you set the fan too low. (red for less than 50% rpm, blue anything over. i assume)

Cons: none

Other Thoughts: none again

Pros: Controls my fans with ease, installation was a breeze.
Love the red and blue LED'S

Cons: Although a little on the bright side, i have no clue why people would be starring at them when they should be looking at there monitor.

If there too bright for you, nothing that a little piece of electrical tape can't fix.

Pros: This thing works like it should and doesn't take up much space. I've bought two of these things. One for myself and one for a friends build. It's not something to get all excited about but like I said, it works and it does what I wanted it to.

Cons: Well let me say that this is not the controller you want to get if you are connecting an insane number of fans in your case. You might have to piggy back a couple fans to get this to control your whole case (which I did). But I knew that going into it so I can't deduct an egg for it.

The lights are a bit bright. It gives the room an ambient blue glow when I turn the lights out. Not a con for me cause I like that but I would caution against staring straight into it. It burns like a laser!!!

Other Thoughts: I am Awesome. Nothing Follows.

Pros: Fan controller works as advertised.
Bright led lights.
Came with several extra cables for various obscure cable adaptations.

Cons: 1. BRIGHT led lights. Fixed by pushing the leds back a ways into their sockets (ty other review writers for that tip)
2. HEAT. The amount of heat this thing generates almost negates the need for a fan controller as you have to crank up the fans to make up for it.

Other Thoughts: more 3 pin extensions would have been great as placing this in your top drive bay would be ideal. Having this under my dvd drive bothers me as I don't like the extra heat while playing my movies
