3 out of 5 eggsI can't hear myself type this review.

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: -Cool looking. Green LED in my green case? MUCH SWAG.
-Spins like... errr... a VERY fast merry-go-swoosh.

Cons: -Can you hear the sound my keyboard makes as I type this? Me neither. I fear for my eardrums. Thing is loud, and I mean LOUD. I thought my old one, which was passed 5 years of use, was loud, but this? It's like putting some System of a Down to put a kid to sleep.

Other Thoughts: -From what I've read, they're either spy-silent or deathmetal-loud. The gamble is yours to undertake. Other than that, yes, they look super cool. I just wish it didn't try to overpower me through the power of sound. Do my speakers try to cool me off? Nope. To each their purpose.

4 out of 5 eggsGreat Product! super awesome!

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: It's green! Green is cool, I REALLY like green. I order five of these bad ♥♥♥♥♥♥, slightly quieter then my previous fans. Had for 2-3 weeks at the time of this review. (4/5/2016) No problems except for only one defective fan.

Cons: Kind of loud, past 1500 RPM.
One of the fans has a slight imbalance. (barrings might be shot?)

Other Thoughts: Have them mounted in a cool master xb with a cool master evo 12 CPU cooler.

The "unbalanced" fan has been moved to the back of the case for exhaust. Makes my case vibrate just a bit, enough to be noticeable. If I could give 4.5 eggs I would but for now I will do 4. I'd give a 5 if I can get the one fan replaced.

5 out of 5 eggsGreat product! Works perfectly! Very happy!

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Great aesthetics, functionality, and affordability!

Cons: The original cord for plugging it into the motherboard could be longer, but I imagine that's why the adapter was included.

4 out of 5 eggsLoud

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: The fans definitely move a lot of air and the LEDs on them have a great green color. So in that aspect, they do what they're intended to do.

Cons: The biggest problem I have with these fans are that they are EXTREMELY LOUD! I mean to the point that if my girlfriend is watching TV in the same room with me, she has to turn the TV way up to compensate for the noise. It's not a low hum. I have 6 in my case at the moment and it's unbearable. Will definitely be looking for more quiet fans.

Other Thoughts: If you don't mind noise, then these will work great for you. They most certainly are not silent though

3 out of 5 eggs1 good and 1 Bad

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: looks cool
If you get a good one, they appear to be very quiet

Cons: If you get a bad one, it's very loud

Other Thoughts: Bought 2 of these and one is very quiet and the other is loud as heck. Had to pull the bad one out of the case. Way too noisy. It makes me question the quality and how long the other one is going to last.

4 out of 5 eggs

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Love the green LED and can go at a very high RPM 4000
Easy to screw in

Cons: Loud at 1500RPM or higher and can only go to 1080RPM lowest still somewhat loud well not really

Other Thoughts: Cool green fan if you can take the noise of it at 1080rpm sound is like a 3/10 at 1080rpm

4 out of 5 eggsCooler Master SickleFlow 120

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: + Cheap
+ Beautiful LED's if you are into LED fans

Cons: - My only con is an uncertainty, so check out the other thoughts.

Other Thoughts: The fan at max power is rather loud. Not like vacuum cleaner loud, but definitely louder than a laptop fan. This wouldn't be a problem if I could control one of the fans that I bought. One works perfectly. I can move the speed up or down whenever I want either from the BIOS or Speedfan software. The other, on the other hand, can't be controlled. I've plugged it into two separate ports on my mobo (Chassis Fan 1 and Power Fan 1), yet neither give me the access I need to shut it up. So it is either that the ports on my mobo don't work correctly (unlikely that 2 ports wouldn't work correctly), or that the fan I received cannot go below its max setting (also unlikely, as the motherboard should be the one limiting the amount of electricity going to the fan, not the fan limiting the electricity it draws). What I find even more bizarre is that my BIOS screen detects it (I have 3 Chassis fans plugged in and 1 CPU fan, and my BIOS will display 4 fans plugged in), and I can change the levels of the fan there, but it won't change after saving changes and booting up Windows. Granted this fan is keeping the system at about 30 degrees Celsius, but if I want to keep it on all night to keep a server running, I barely get any sleep. I'm not talking about a heavy duty server, just a Minecraft server, but still I need internet connection, which doesn't exist in a sleep state or a powered off state. I could always unplug the fan before I sleep, but, even though it's not that hard, I always run the risk of burning my hand on the mobo's 990FX chip. And I shouldn't have to unplug the fan in the first place. If anyone else owns the ASRock 990FX Extreme6 AM3+ mobo, they can either verify or deny that it is the mobo's fault.

4 out of 5 eggsWorth it for the price

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Green LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Depending the on speed your running them at, they can be whisper quiet or moderately loud. They do run smoothly and you can't beat the price.

Cons: Well I bought 4 roughly a week ago and 3 work great but the fourth one maked a rattling noise. Would like a replacement fan. I will keep the rating at four until after the customer service experience.
