5 out of 5 eggsGreat Value

Pros: I had bought these fans back in 2009 for my old rig and they worked flawlessly since then. I recently built a new rig and so bought these 2 again. They are pretty whisper quiet and the LED lights are bright as!

Cons: The screws need like brute force to screw all the way in. It almost feels like you will snap the fan plastic any second but it takes some force to make the screws flush against the fans plastic surface.

Other Thoughts: I wish Cooler Master made the cable in black color that sticks out of the Fan. It just blends in better with your case color which is mostly black

4 out of 5 eggsGood fans for the $$$

Pros: These are some very good low budget fans that actually cool pretty well. Although people say that setting this fan horizontally doesn't suck much air out (for an exhaust fan) and I will have to disagree. For some reason the top (horizontal) exhaust fan exhausts more air than the rear exhaust fan. Crazy, I know.

The LEDs are nice and bright and look gorgeous at night. And actually keep my case pretty cool. GPU/ CPU temps stay relatively the same temperature with barely any changes.

Cons: Tightening the fans will leave the blades scrapping the sides. I'd suggest not to tighten these up a lot. I don't know why, but that what happened to me.

I just loosed the screws a little and the screeching stopped.

Other Thoughts: Good fans for the price. If you dont want to spend a lot on fans, get these.

4 out of 5 eggsWhisper quiet

Pros: Ok, absolutely no sound coming from this fan unless your ear is within 8" or so.

Cons: I'm not sure its really moving enough air to be worth the ultra quiet operation...? Maybe a little noise might be worth having if more air was moving.

5 out of 5 eggsDoes what they're supposed to do.

Pros: Nice and bright.

Cons: Didn’t quite match the blue in my PC, but that’s only a minor concern, and not the product’s fault. Also, the fans are loud in their stock configuration; you must plug them into a fan controller or a header with motherboard control if you want to bring the noise down to tolerable levels. Again, this is merely a personal issue. Absolutely nothing wrong with the product itself

Other Thoughts: The product works, and works well. They're fans. Not sure what more you can expect from them.

5 out of 5 eggsGreat fans. Bright leds.

Pros: Great quiet fans that move a decent amount of air. I purchased 4 of these for a midsize case and it dropped my temps by 10c. I will be buying more for my own full size system.

Cons: The lights on mine are pretty bright. So if anyone has a clear side panel case, your room is going to be blue in the spot these fans are at.

5 out of 5 eggsSilent fans

Pros: Nothing beloew amazing, I recently had 2 80mm fans with a few dead LED's and a stock 120mm fan that came with my case. i Purchased 2 of these on sale and 2 of the 140mm versions and i couldnt be more pleased. they are very quiet, especially compared to my 80mm fans and now my case runs about 10-15 degrees cooler

Cons: none what so ever. GREAT PRODUCT!!!!

Other Thoughts: They are fans. Fans move air. They arent %100 silent but with my fan controller set to max, I can only hear them in I pay close attention. for those who think they are noisy must constantly have their ear resting on the the case/fan in a dead silent room...

I am using;
1 120mm intake fan on the bottom.
1 120mm intake fan on the front(stock fan in case)
1 120mm exaust fan(rear)
2 140mm exaust fans(top)
and the 2 side fan mounts are open and usually act as an intake when my CPU/GPU fans ramp up and my case never gets over 36c
