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.

3 out of 5 eggsLouder than I expected

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

Pros: Great air flow and has great static pressure

Cons: It was noticeably loud, almost like a high pitch humming. It was very distracting and had to take it out. Unless you have a fan controller to lower the RPMs, I wouldn't buy this product.

Other Thoughts: Hope this helps!!

4 out of 5 eggsNice fans. Great color

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

Pros: Whisper quiet at low RPMs, price, nice "sickle" blade design that will move lots of air, very nice deep green LED glow. Really like the smoke tinted plastic as well.

Cons: Can be a bit loud at max RPMs, cables are not very long and are not black for those mounting on a window, too early to tell but might have longevity issues. I do have one making a little bit of a grinding noise every now and then. Sounds like its coming from the bearings. I will monitor it to see if it continues.

Other Thoughts: I bought 6 of these to put in a Corsair carbide 300r widowed case, all hooked up to a NZXT SEN-MIX2 fan controller. They look really mean!! On low settings they are super quiet while still moving tons of air throughout the case. On high settings, they will let you know they are working, but that is overkill in most situations for my setup. Even while gaming, i only crank 4 of 6 them halfway and they provide more than enough air flow for nice temps. As stated by others, I did find that the fans I have that are mounted (intake) behind mesh are in-fact quieter than those mounted (intake) behind plexiglass with holes drilled for airflow. But that's just an observation listening up close (less than a foot away). Doesn't bother me at all and more than a few feet away can't tell at all really. I do wish that the cables were black for hiding them easier. I do recommend these fans especially with a fan controller.

4 out of 5 eggsGreen is good

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

Pros: Moves a TON of air, cheap for not being blue or red, dig the smoked grey look of the plastic, looks 30 times better than glossy black.

Cons: Louder than expected

Other Thoughts: I got this for a silverstone sugo series front fan. This thing friggen MOVES some air. My cpu fan barely spins up during gaming and temps stay below 30c cause this thing is a beast, unfortunately my cpu fan is quieter at full speed than this one lol. As others had mentioned i think the fact that the fan has some obstruction in front of it (fan filter and grille) makes it a lot louder. I plugged it in before installation to make sure it worked and it was not as loud as when installed. I have another 120mm slim fan that has a higher db rating but is much quieter than this one. Other than that observation this is a solid fan for airflow, i wouldn't put this on a radiator or anything though

5 out of 5 eggsNice, Cheap, Green LED Fan

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

Pros: - Good amount of Airflow
- Nice Deep Green LED
- Quiet

Cons: - None

Other Thoughts: I was surprised with how decent this fan actually is. The fan moves a good amount of air, and is quiet under most conditions. I did notice however, that when restricted, like in the front of a case, the fans do get noticeably louder. My only concern with this fan is going to be longevity. I have had it running 24/7 for about two months now without any issues, but I fear it won't last as long as a more expensive fan would.
