4 out of 5 eggs

Pros: -Moves good amount of air
-Blue LEDs and clear plastic body look great
-Cheap in price, good in quality

Cons: -Somewhat noisy

Other Thoughts: Very good budget 140mm LED fan, but definitely makes a slight bit of noise especially at higher speeds.

Definitely a good idea to use motherboard fan control or a separate fan controller so it doesn't get distracting.

5 out of 5 eggsWorks well and lights up

Pros: It lights up quite bright, and it moves air decently for where I put it In my computer's case. I cant hear much noise coming from it. However, I haven't adjusted any fan speeds yet to see if higher speeds make much noise or not.

Cons: The light this fan produces may be to bright for some, but I like it. Might be considered noisy by some.

Other Thoughts: I would buy another If I needed more 140mm fans.

4 out of 5 eggs7 months still going

Pros: Smooth air flow. It's not noisy. It looks good if you keep it clean. It was easy to mount. I have some horror stories about mounting fans.

Cons: I did not receive the 5 dollar rebate. Number one reason why I purchased this fan. I can't knock CM CS. They've been great thus far. I'll consider a competitor for cooling components from this point forward. Minus 1 egg. It feels like a 3 1/2 though.

Other Thoughts: I mailed this rebate out along side another rebate from product I purchased the same day. The other product's rebate arrived within 2 months. The last time I checked this rebate status it said "Waiting for my letter." Something to that regard. A few months went by. I checked the tracking today. No record. This is the first time I ever lost a rebate. The letter never came back.

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.
