The fan works great and the color and brightness of the LEDs is also great! Would buy more when needed!

There isn't much to it, it isn't all too loud but definately moves some air, and installation was easy. Confused about the direction of the airflow? Air flows towards the inner side of the curve on the fins on these types of fans, in this case, the side of the fan that everything is mounted on.

I installed this fan in the top of my case. It was very loud so i thought i had it installed upside down or something. After flipping it around it is still loud. I have to hit the top of the case every once in a while to get it to shut up. lol. Good fan if you do not mind the annoying sound of weed eater next to you.

two out of four dead after six months.

Bought two for my antec 900 case, airflow on these is great! Very happy with these.

I bought three of these to fill out my new case. My new case already had one of these installed along with two regular fans. Since my new case has a green tinted window, these are a magnificent complement to its overall green theme, gives a GREEN glow to my case insides and reun very quietly to boot! Would recommend to anyone who likes green.

this is a great fan. i have 5 of them in my case right now and i am very impressed with the amount of air the blow into my case. when i take my side panle off and hold my hand 3 feet away from it i can still feel it as if i was holding my hand 3 inches away from it. altogether it is the best fan ive ever purchased.

Purchased this to add to my Cooler Master CM 690 case. I monted it on the bottum, and it does fine. It's a little loud, I will have to get gaskets to cut down on the vibration, but it makes the already green lighted motif look even better.

Comment:
I installed 3 of them. Really dresses up the case ! Even cooler if it had circular motion.

fan moves quite a bit of air keeps computer cool.

I have three of these fans installed, and they move a lot of air. a little noisy, but not untolerable. very cool green color. seem to be very sturdy, and have never had a problem with any of them yet after 4 months.

Good fan. Air flow is great, I ordered 2 but forgot to measure what I needed, one was too large, my fault. Just about as noisy as the stock fan on my Case, not too bad. I would buy more if needed.

Excellent fan. Great Airflow and is fairly quiet. I highly recommend these fans as outlet fans only. They tend to make a whirring noise if used as an inlet fan and are mounted close to honeycomb type holes in the case much like you would find in the side panel. If the air is unobstructed or a mesh or sponge filter is used on the fan's inlet side they are very quiet and do flow tonnes of air. I have 4 in my case along with 3 fans that came with the case. I moved these particular fans to outlet positions except for the one behind the front grill (just a mesh filter there). The fans that came with the case are mounted on the bottom and side panel and still make noise but it is a much quieter buzzing noise instead of a high pitch whirr.

No issues. Easy install. I'm running two, plus the CPU cooler. It is louder than I hoped, but much quieter than I feared.

Comment:
This fan sucks in lots of air. The down side about it is more louder then my stock fans. The green lights are awesome. I would recommend this product.

The fan looks awesome. Its very loud and makes a rattling noise. i ran it about 10 minutes and unplugged it because i was so annoyed. i guess it would be a great fan if you cant hear.
