Pros: -fairly quiet.
-blows air.
-the main reason I got it, looks fantastic.
haven't played around with different colours as the standard red works well with my current build.

Cons: really none, I am not a big fun of the fact that it is kind of just a clip on.(no screws or anything holding it to the motherboard). but it seems fairly snug, maybe will come off if you tend to get angry and throw your computer out the window a lot.

Other Thoughts: CAUTION: IF YOU HAVE A LARGE CPU COOLER.

on certain motherboards this can conflict slightly with cpu coolers, I had to re adjust my liquid coolant pipes to fit this in, not a huge problem, just like to let people know. if your pipes or anything is close to your ram before you get this, you need at least 1-2" around the ram.

Pros: Great build design, had no problems mounting it over my RAM

Cons: Have not found any yet.

Other Thoughts: Don't listen to uninformed and ignorant reviewers. This works totally fine as a standalone unit; however, if you wish to change that colors of the LED that will require a Corsair Link. If you are like me and red is your color, there is no problem.

Pros: Looks good
Works great
Well built
Quieter than expected
Simple installation if installing only a single cooler

Cons: Bought two of these for one mobo but only one cooler fits. There isn't enough room between DIMM slots and GPU backplate for cooler mounting bracket closest to rear of case on second bank of DIMM slots for the second cooler. I had to machine the GPU backplate to make bracket fit.
One cooler was missing 4 bracket mounting screws when I opened the box.

Pros: looks cool. Hopefully runs silent (I just received all my new parts for build and in examining them is when I discovered the below issue).

Cons: Do NOT listen to Sonya L. You can not change the LED color without a Corsair Link Device. Either the "commander mini" or the "link lighting node" will work, but they are near impossible to find for sale. Alternatively, It seems if you have one of Corsair's "all in one" H??? series CPU water coolers that you can plug the LED strip into that as well. I run a custom water loop though so that wasn't an option.

Other Thoughts: I found a "corsair commander mini" in stock somewhere and bought one to use with this. I also have a corsair 1200i psu, so I will be plugging that into the commander mini as my mobo only has 1 spare usb 2.0 connection. The corsair link lighting node can also be plugged into the commander mini, which I plan to do if I can ever find one. As of now I can't find a single place selling one.

Pros: corsair

Cons: I don't have it yet..

Other Thoughts: Omars' review is inaccurate. No need to purchase link, no shipping fees like he claims. Link is a download program you get from Corsair website install and then you should be able to change the color of LEDs. However if you're using windows 8 or 8.1 you will need to look around their forums for the registry hack otherwise it will any devices (unless they've updated their software since February).

Pros: These things look awesome and the build quality is what you would expect out of a company like Corsair

Cons: Just red color and you can't change fan speed fan you need to buy corsair link to change another color and corsair link not available only on corsair web and ship charge tax charge.

Other Thoughts: i don't know why not available on newegg or other web

Pros: Added a real nice touch to my case, it glows red by default but if you go to their website and download the software to it it can glow other colors.

Cons: Zero con's!!!!!
