1 out of 5 eggsSo loud!

Pros: Moves nice volume of air

Cons: It is so loud it sounds like the case is getting ready to take off with 2 of these in it!

Other Thoughts: Won't buy it again, may be "cooler master" but "noise master" would be better choice. Even at this price it is NOT a deal! Unless you like a constant HHMMMMMMhhhhmmmmmhHHHMMMMMMMhhhhmmmmmHHHHMMMMMMhhhhmmmmmmHHHHHHMMMM!!!!!!

5 out of 5 eggsCoolMaster SickleFlow 120mm

Pros: --Really quiet, I mean, it's really quiet
--Affordable (under $10.00 USD)

Cons: --Could use longer 3-pin wires. If you're using this as a front 120mm fan pusher, I recommend buying a 3-pin wire extension.

Other Thoughts: Great fan and buy for those looking for a quiet case fan. If your a cheap case fan buyer (like me) and looking for no-noise fans, this is the fan for you.

People that rate this fan as loud really needs to get their ears checked out. It's really quiet.

Just don't expect great cooling capability and CFM from this unit.

4 out of 5 eggsshort cord

Pros: it moves air pretty well. im using this particular one for an exhaust fan in rear of case.

Cons: not silent. it hums, but its not dead silent. also the power cord is kinda short for reaching the fan headers on my mobo. only 10" cord. luckily it does come with a molex adapter plug to integrate it into the main harness.

5 out of 5 eggsQuiet

Pros: Quality, comes with screws, three pin fan

Cons: don't move as much air as I expected them too

Other Thoughts: I bought these for a new build, the case has a fan at top front and back but none on the door. I bought these to pull air into the case and blow over the video card, single card now but I might go sli in the future. Easy to install just remember that label sucks air and motor mount (you can tell) blows air, there are often arrows on the fan that indicate direction air moves as well, if these have it I didn't spot it on the fan. I'm using a fan controller temperature monitor gadget and these are hooked into a Y adapter before being plugged into the monitor.

3 out of 5 eggsYou get what you pay for.

Pros: $8/fan that blows decent CFM and is relatively quiet.

Cons: I bought 9 of these fans for my case. All fans on intake duty had a dust screen in front of them. After 4 years of use, 4 of the 9 fans still function. The rest all died. Some developed a whine, some stopped spinning and locked up hard, some just failed to pull sufficient RPM (you could see the blades spinning, and the lightest touch would fully stop them).

I mean, ok, for $8 I can't be too mad, I got 4 years of service out of them with an average duty cycle of 7 hours per day. But compare that to the two Noctua fans which move as much, if not more, CFM, don't need constantly cleaning (dust builds up on the fan blades of these), are SILENT at full RPM, and have been running in a MUCH hotter environment (CPU heatsink, dealing with 70C air instead of 20-30C air) and are still going strong.

5 out of 5 eggsSweet Airflow

Pros: This fan moves air unlike most fans that come pre-installed with a case you may purchase. It features a black body build, and with that, blends into any black case you may have. Or add some contrast to your white case with this baby!

Runs nice and quiet when operating normally, but can get a bit more audible when sped up. That's perfect for me though, because the sound of clean, moving airflow excites me when in a PC. Reminds me of an awesome server rack, ready to roar with it's processing power.

Cons: For the most part, there are no cons at all! Though when this fan is at max speed 100%, it moves so much air, it gets a weeee bit loud. But that's the sweet sound of your PC being chilled, boys and girls. :]

Other Thoughts: The price is blehh, try to catch it on sale! CoolerMaster is a good brand for Fans. :)

1 out of 5 eggs

Pros: Moves air

Cons: I installed 3 of these fans in the front of my Antec 1200V3 tower thinking I would get quitter fans with about the same air flow but I was wrong. Being it is a good 2 hour job to install these fans with good cable management. I was VERY disappointed when I powered up my computer for the first hour, the fans are very noisy but they are advertised to be actually a very quiet fan BUT THEY ARE NOT. The fans as they run made a humming (womb sound) sound, and that is now all I can hear when the computer is running. What I had to do tonight is buy a Zalman ZM-MC1 Power Connector from Power Supply to Fan (3pin) 2x5V 2X12V. I will install this on 2 of the fans to reduce voltage, which in theory will reduce noise but I am punished by then reducing airflow, which is so very important in a computer case. Overall I am VERY disappointed with ALL the Cooler Master fans I have received these are no exception.

1 out of 5 eggs

Pros: pushes a lot of air and can be set to a specific speed that you want.

Cons: The fan was running fine for about a year and 8 months. However it just broke. When connected it goes to a max speed and then stops completely, then it restarts and again does the same thing continuously goes to max speed and stops completely again. I tried putting it on a friends computer and it does the same. There is also a very loud noise as its trying to get to the max level.

Other Thoughts: So the fan is advertised as working a maximum of 50,000 hours. I have had it for a little less then a year and 8 months. Even if i had it running for every minute of that time period (which it wasn't), it would give me about 14400 hours of running time. I feel very let down with cooler master as i buy a lot of products from them. For the fan to not even run a third of its max life time is disappointing.
