Pros: good

Cons: non at all

Other Thoughts: good

Pros: Quality capacitors for a very granular and consistent control
Brushed aluminum finish
My model had no labels and markings, which makes it even better!
Customizable leds

Cons: They ask to connect all 3 molex on it. Manual isn't clear if we should connect via 3 separate cables or not to the PSU. I used 3 diff but that's like a lot of cabling for that thing. Not sure what's the point of the 3 molex either. I have some notion of electronics and the wiring doesn't exactly makes sense as it all feed in one place in the end.

Other Thoughts: Using this for an air cooled machine with 8x 140 fans. Able to control them perfectly to achieve balance between silence and effective cooling. My first fan controller and certainly a brand that I will keep in mind for future builds. It's also keeping my fans off my motherboard so that I don't have to worry about them attacking my expensive other parts.

Pros: -Super easy to implement into your current build
-Customizable LED colors for each individual knob
-Super accurate speed control

Cons: Only con I have is when I received this product the #1 knob was not hot glued on properly. It was loose in the package. My guess is that when they glue the button in place it was not pressed on long enough. No big deal I just had to re-glue it back in place with hot glue.

Pros: Amazing super linear power delivery!

Cons: Had to cut off series molex and but-splice direct to psu since it's like 30A draw

Other Thoughts: If you want a 8 channel controller with 30w @ 12v look no further!

Pros: Independent control over 6 fans. Ability to turn fans completely off. Different LED schemes so you can tell which fan is which. Full control over fan speed.

Cons: nada

Other Thoughts: I love this fan controller. I have an Antec 1100 with 8 fans and I wanted and I wanted to set them independently. Every fan I have has a level right before it gets audible. With this controller I can find the sweet spot on all 8 fans for adequate cooling and low noise. Forget getting a cheapy and invest in true fan control! Heavily overclocked machine and very cool and quiet!

Pros: I bought two units of these so you can multiply everything by two.

-8 channels, all of them work
-8 detachable cables, great if not using all channels
-Simple nob interface, easy to use
-LED's are bright enough to see but not over bearing
-Easy to install on case
-Good sturdy design
-Can set fan speed to 0 if desired
-Has a mini heat sink for each channel

Cons: -One of the detachable cables didn't work. I did buy two of these so only 1/16 cables failed. Not a huge issue.
-Power cables are a little short and add some clutter to the case if you care about cable management that much. Not a huge issue for me as my power cables are long enough to reach the top of my case.
-Price is a little high but for 8 channels I won't complain too much

Other Thoughts: The two of these I bought were a build saver. I upgraded to the Rosewill Blackhawk and had more fans than my previous two 5-channel controllers could handle. Needless to say, I am running 20 fans on 16 channels and I have no issues what so ever. I can control the noise level and the cooling by the twist of the nob. You can set each individual channel to a different color so you know which fans you are controlling at any time. Two of the colors are similar but that isn't a big deal.

Over all these things are great and will fit right into your build.
