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.

5 out of 5 eggsNeed air, you got air!

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

Pros: I purchased these for three reasons, the amazing reviews, the CFM, and they go with the color scheme I have. Combine these with a fan controller and these are BEAST. I am actually looking for a new case and, if I can, I plan to have a case that can house 1-3 more of these. Again they are amazing and push air at 60% utilization and even more at 100%.

Cons: They push more air than my girlfriend.

4 out of 5 eggsQuiet Fan, lasted a year and a half

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 a quiet fan, and moves a lot of air.

Cons: Died after a year and 4 months. Fans usually have a life expectancy of 2.5 to 5 years.

Other Thoughts: I'll probably buy again.

4 out of 5 eggsdecent fans,

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

Pros: good fans cheap moves plenty of air.

Cons: they rattle if they are upside down. I have 2 of these in my in-win ironclad case and they are upside down to pull air out of the top of the case, and they rattle when they are turned on and takes about 10 minutes for them to stop.

Other Thoughts: and yes I even have the green modright fan silencers installed between the fan's and case.

3 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: Looks very cool

Cons: See below

Other Thoughts: So this fan looks great and all, but the one I got, for whatever reason, is extremely noisy. I thought grabbing a fan controller would help, but running it at lower voltages causes it to make this annoying whirring sound. It's either that or it sounds like a large oscillating fan, the sort you have in your bedroom. TL;DR: Don't buy it for a silent rig.

5 out of 5 eggsI'm a fan

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

Pros: Easy, very very easy to install. I was able to plug it directly into my motherboard to take advantage of the autofan functions run by CMOS. Came with four screws, has four holes. This may not seem significant, but you'd be surprised.
Okay, now for the technical...
Using a DIY PC "Solar" atx mid case
EVGA 600w B PSU
EVGA 790i FTW sli motherboard
GTX 550ti FPB x 2 in SLI
Freezer Pro 7 CPU cooler
Left 1 of 2 included fans in the case, replaced the exhaust fan with the Sickleflow.
The air movement seems to have DOUBLED. My case is up on my desk, away from the evil dust bunnies on the floor. The fan is actually strong enough to move the tags on my cables behind the case, and the curtain over the window that it's next to. Not a lot mind you, but I can SEE visible sign of airflow, whereas before I had not. The green LEDs are a radioactive green shade, very nice and bright. I actually had a dual cathode kit in my case, and had to move one of the tubes away from the fan. (Mostly to evenly distribute light and avoid intensely bright spots) Great fan, great price.

Cons: I can't really think of any. Maybe an arrow on the housing to indicate direction of wind flow? I didn't really look to see if it had one though.

5 out of 5 eggsVERY efficient!

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

Pros: These fans move ALOT of air and the green LED's look fantastic. They do what they should and come with all cords and mounting hardware.

Cons: None.

Other Thoughts: I installed 2 of these in my Raidmax Cobra case. Replaced the rear fan with one of these and installed the other as a top mount exhaust fan. My case temps went from 37c to 29c-32c under medium/high load. My CPU even dropped from 45c to 40c-41c under medium/high load. Running a AMD FX-6300 with a GTX-760 GPU just for the info and my case has one front mount 120mm intake fan, one of these rear exhaust fans and another for top mount exhaust. Again, all I can say is these are great AND cheap...just buy them.
