4 out of 5 eggsGood if noise is not an issue

Pros: These are good fans for the price when it comes to airflow and also comes to the color and brightness of the led. They are bright with a nice smokey blue look while on, and they do help keep the chassis cooler. I got two of these for around 13 dollars and that was a decent deal for them if I needed more fans that pushed decent airflow for a good price I would probably recommend these depending what your preferences were.

Cons: Noise level is high, especially when max rpm( I used a fan controller with these fans) and the noise is fine at 5v and is manageable at 7v...but 12v is the loudest noise coming from my case and it disturbs the hell out of me when I am only listening to that.

Other Thoughts: Good fans just makes sure you do no care about noise levels beofe putting this in your build or if you do that you have this hooked up toa fan controller to help keep it at a lower rpm.

4 out of 5 eggsQuiet fan, loud LEDs

Pros: Quiet and bright, it does the job taking in an acceptable amount of air.

Cons: Is not the same size as the 140mm fans on the front of the AZZA Solano 1000 case. It won't fit into the plastic shroud of the original and the screw holes are farther apart. It shames me but I used duct tape to keep these attached to the hard drive caddies. It's practically invisible and it works.

Other Thoughts: I'd rather use duct tape than return it for the proper size if that says anything about it.

5 out of 5 eggsGood 140mm Fan, pretty quiet

Pros: Pretty quiet
decent airflow

Cons: could be a bit cheaper
not completely silent
No on off LED switch

Other Thoughts: I have a case using 3 of these fans, they keep my components cool and are pretty quiet while doing so. Compared to other pc case fans they are pretty cheap, but I think case fans are overpriced as a whole.

I can hear the fans running about a foot and a half away from my tower where I sit, but it is hardly noticeable.

5 out of 5 eggsNice for the price.

Pros: Not silent, but very quiet at 100%. Mine is mounted on the top of my case to push air out. It works very well for this. If it was loud, it would be noticed. For the price, you can't beat it.

Cons: None really. Unless you don't like giant bright blue fans.

5 out of 5 eggs  works well

Pros: It's a fan. Pushes and pulls air. It's not as quiet as I expected. But I used a fan controller. Lowering speed will lower led brightness also.

Cons: Cable is so short I had to extend it. It's probably 10 inches. Could use another 5-6 to route through case

Other Thoughts: They got cheaper 2 days after I bought them...

3 out of 5 eggsColor doesn't match the 120mm

Pros: Very quiet and moves lots of air.

Cons: This fan's LEDs didn't match the 4 120mm versions that I bought. Actually, it matched 1 on the 4. Both this one, and one of my 120mm fans are a lighter blue than the rest. Not too big of a deal, but I am particular about things like that. It just looks odd, when the colors don't match. Would have been 5 eggs if not for the mis-match color.

Other Thoughts: Careful when trying to match with the 120mm versions. Seems like Cooler Master may have switched the color on their LED's, and this may not match.
