2 out of 5 eggsvery noisy

Pros: free AR. shouldn't have complain too much.

Cons: But, it is very noisy. It said to be 16 dBA. Don't trust it. It should be well over 23 dBA.

5 out of 5 eggsCooler Master 140mm Blue LED Silent Fan

Pros: Bright Led looks great
easy to install
fits perfectly

Cons: no cons

Other Thoughts: If you want to dress your rig up can`t go wrong with led lights , I replaced my back fan and ordered 2 120MM fans for bottom of my case to provide more led lighting :)

3 out of 5 eggsnot the best 140mm fan

Pros: Comes with both design connectors. has blue led's. fan is near silent as designed

Cons: Fan is silent, but also doesn't push very much volume of air, so that's the offset I guess. I needed a blue fan and so I bought this. I thought with it having a name brand like cooler master and they make cases, this would be a good one. No, they make some cheap items like every one.

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.
