3 out of 5 eggsLOUD but effective...

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

Pros: It moves air like there's no tomorrow. It actually broke skin on my finger once when I touched the blades... THAT'S how much power and torque it has. It also looks really cool with the LED's on, but you can only REALLY see them if it's an intake fan or you have a window.

Cons: LOUD. Like, OBNOXIOUSLY LOUD. If you use a headset you may not hear it, but still... it ROARS even turned to the minimum speed.

Other Thoughts: If you need this for a computer or something that really really NEEDS the power, go for it. Otherwise, spend a few more bucks and get something with a teeny bit less power and get some peace and quiet.

3 out of 5 eggsPretty Good overall

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

Pros: fast and pretty darn quiet. pretty well built overall

Cons: only reason this didn't get a perfect:

1) i ordered 5. each one has 4 leds on the corners. one of the 5 came with a broken one and i'm too lazy to RMA just one for something this cheap. ($7.99-$5 rebate=$2.99). 3/4 leds still glow on this one.

2) there may be a way on the bios to set fan speed, but i don't know. as far as i know it's one speed

Other Thoughts: needs a speed control, personally i preger a switch that you can manually set like some other manufacturers, but this is still quieter. i would still buy more.

4 out of 5 eggsGood Fans

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

Pros: These Fans push a good amount of air and are not very loud. Sleek black design.

Cons: Led's are pretty dull, not very bright. Look more like red dots instead a red glow.

Other Thoughts: Good fan in regards to the fan features and considering the cheap price a good buy, but if your looking for better cosmetic glow. look elsewhere.

5 out of 5 eggsGreat fan 0.37 amp model

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

Pros: Lots of airflow. Suitable for use with liquid cooling next to radiator, at back of case, side of case or top exhaust.

Cons: NONE.

Other Thoughts: This is the powerful 0.37 amp model fan. It blows hard and a lot of air so it makes more noise at full speed. You can probably control speed if plugged into motherboard.
Cooler Master also makes a less powerful 0.16 amp fan which moves less air and makes less noise. I think people do not understand the difference between the 2 choices. The 0.16 amp fan usually comes pre-installed in the case while the 0.37 amp fan comes with the liquid coolers or available separately.

Know what to buy and you won't be dissapointed.

5 out of 5 eggs

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

Pros: Good Fan, Moves a good amount of air around

Cons: None

Other Thoughts: One thing to keep in mind for when you are purchasing this product is that the LEDs are very dim so if you are looking for something to light up your case then this is not for you

2 out of 5 eggshorizontal position - look else where

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

Pros: +good price
+I like the LEDS

Cons: -Noisy fan in horizontal fan (bottom of the case)
-Fan doesn't move in a focused direct for of a fountain spread of air movement.
-barely can feel the air movement.
-I believe the specs to be factitious.

Other Thoughts: I bought two of these and going to change them out for Corsair Fans.

5 out of 5 eggsQUIET!

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

Pros: -Nice profile
-QUIET!!!
-LEDs are nice for ambience

They function very well
