5 out of 5 eggsNice fans.

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: Ordered two of these. They move a lot of air, and are surprisingly quiet.

I mounted both on top of the case. The one towards the front of the case blows air down across the RAM and Processor, and the second one I have set up as an exhaust.

Cons: n/a

Other Thoughts: If the longevity of these is good, then they'll be my new favorite fan.

3 out of 5 eggs4 of 4 fans unbalanced

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: The fans are great at moving are close silent

Cons: I purchased 5 of these fans an all are unblanced. This is VERY pronounced when the fan is mounted on the side panel of a HAF 912.

5 out of 5 eggsMoves Air - Quiet - Good Comparison?

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: Quiet as advertised. Moves a lot of air as advertised.

Cons: The only con I have is I bought 3 of these. All 3 are exhaust fans. (2) on top and (1) on back. One of the 3 got "lazy" after about a week and is NOT moving air like it did. This does not bother me at all.

Other Thoughts: I only rarely leave reviews but came to order more and looking up the exact part I saw I could. I looked up the order to order some more. Compared to their other model fan with half the fins, these make the same amount of noise (not a lot) and move a lot more air. 1 out of 3 is a high potential defect rate, but not scientific. I am going to buy 3 more to blow air in (2) from the front and one from the bottom. (Yeah, it's a mining rig). These fans are great and move a lot more air without the added noise. I will feed back after I get the other 3 and if they are all great it reduces the defect rate. NOTE!!! The fan is NOT defective or noisy, it just has gotten lazy. Perhaps not spinning as fast. These are not on speed control. Direct voltage.

5 out of 5 eggs69cfm and QUIET

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: Very quiet, yet move air? Can't even hear the fans running 2 feet away, with 4 of these in the case.
Move a LOT of air.

Cons: none so far

Other Thoughts: 1 intake (hard drive cooling), 1 exhaust (rear panel), 2 on a large CPU cooler, and very quiet. The sickle shaped blades are much quieter while moving a LOT of air.

5 out of 5 eggsVery quiet for high air flow

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: Rated 69cfm, usually means LOUD? These fans are QUIET and STILL MOVE AIR. My closed-case temps are only 5-degrees above ambient!. Can't even hear them running?

Cons: none, other than they are sleeve bearings.

Other Thoughts: Used to use Silverstone 110cfm fans, but they were so loud it was like having a leaf-blower running in the case. With 4 fans, it was just too loud, even with turning them down.

4 out of 5 eggsFantastic airflow for the price

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: These babies pull a ton of air and fit in well on 120mm cpu coolers.

Cons: WAY louder than advertised. I saw the 21db on the specifications and thought, "oh good that's quieter than what I have now"

Nope. These things are easily pulling 30-35db right now. (put one on cpu cooler and one on front intake) I may uninstall and buy quieter fans sometime soon...

Other Thoughts: Can't go wrong with cooler master, but consider SilenX 120mm fans if you want something quieter.

5 out of 5 eggsNifty

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: It's a nice fan, comes with two different cords so you'll not have to worry about finding the right one to fit your motherboard/side cord.

Had no issues installing it at all.

Cons: It's a bit loud for my tastes, but it pulled the heat right out of my pc tower instantly so it runs like a champ for a long time if you need it to.

Other Thoughts: Maybe if the plastic casing was made a bit more slimmer, but that's just cosmetics so it's just a suggestion.

5 out of 5 eggsGood fan.

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Silent Fan for Computer Cases, CPU Coolers, and Radiators (Smoke Color)

Pros: It is indeed quiet.
It has a nice look.
I can feel the cool.

Cons: None that I can see yet anyway.

Other Thoughts: Would like this in an 80mm if they have it then I'll have to grab it sometime.
