2 out of 5 eggsCheap but noisy

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

Pros: Cheap and looks good. Good selection of LED colors.

Cons: Mediocre air flow but the biggest con is the noise. These things are very whiny (I got 2 of them). Changing aux fan speeds from bios did not change the fan speed, it kept running at 1900rpm. I ended up removing them and using the 80mm fans that came with the case.
Not recommended.

2 out of 5 eggsWhines, dont buy

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

Pros: Moves air, nice green LED

Cons: Whines to the point that it is un-useable

Other Thoughts: I bought 3 of these for a new build, thinking that a nice green light-scheme would look great. The good news is it does look cool, the bad news is that these fans produce an obnoxious and high-pitched whine, making them entirely useless unless you enjoy the sound of a mosquito.The case fans that came with my NZXT s340 (2 fans) are so much better than these. The worst part is return shipping to newegg is barely less than the refund I would get, so i now have 3 free fans, you pay shipping!

TL;DR
spend a little more, get a product you can use

5 out of 5 eggsGreat cooling!

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

Pros: Using these as replacements on my radiators on my liquid cooled gaming build. They dropped the temps by about 3*C over the ones that came with the radiators...which was a nice surprise!

Cons: They are slightly louder than I had thought that they would be

2 out of 5 eggsReplacement fan for cooler master v8 cpu cooler

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

Pros: quiet when first ordered

Cons: at just 6 months and 8 days of operation this fan started making noise, and when i restart my computer windows recognizes that there is a problem with the fan. I have many other cooler master fans and products and have never run across a problem this early on in the equipment's life cycle. I don't believe i will ever buy this product ever again.

Manufacturer Response:

Dear customer,

We sincerely apologize for the trouble you had with our fan. We generally recommend our customers to clean their computers regularly with a compressed air can to increase the life of their fans within their computer. Given that the fan failed less than a 1 year, we can definitely replace it under warranty coverage. Would you be able to contact us so we can replace that fan and make this right?

Respectfully,


CMUSA Support.

3 out of 5 eggsOk

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

Pros: Looks cool. Not too bright. Pulls some good air. Inexpensive

Cons: Comes with a 3-pin connector - can't control it...only runs at 2000 RPM with no control

Manufacturer Response:

Dear Customer,

We sincerely apologize for the trouble you had with our fan. The fan in question requires it be connected to a sys fan 3 pin connector on your motherboard. Once connected, you then use the motherboard's bios to set a fan profile for control of the fan. If you wish to get more help regarding this, please contact us so we can be of assistance.

Respectfully,


CMUSA Support.

3 out of 5 eggsDecent Product

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

Pros: - Moves decent amount of air.
- Red LED light.

Cons: - Not PWM
- Doesn't seem like high quality build
- Started to make slight rattle after a year or so.

Other Thoughts: Nothing really much say about this fan, it's okay I suppose moves decent amount of air. However it did started to make a slight rattle noise after a year, make sure to clean or blow the dust of the blades which could also be the problem. The fan looks cheaply made as well.

I moved on to COUGAR fans and honestly they are far more superior all around such as built quality they seem more sturdy, PWM feature, and affordable price.

5 out of 5 eggsRun Quiet, Look Great

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

Pros: Push a lot of air
Run quiet
Red LEDs!

Cons: None

Other Thoughts: My latest ultimate gaming rig build features a red motif, so these CoolerMaster red LED 120mm fans were a natural choice. I am really impressed with the lack of noise and the amount of air they push at normal running RPMs. CoolerMaster isn't kidding when they bill these as "Silent" fans.

Bottom Line:
A great 120mm fan at a ridiculously low price point that pushes a ton of air in almost complete silence while putting off a sultry red glow. Gaming PC Nirvana!

3 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: Works great

Cons: If you're trying to illuminate your system with this fan, it's not bright whatsoever. It'll barely light up the region 2 inches from it.

Manufacturer Response:

Dear Customer,

We sincerely apologize for the trouble you had with our fan. Would you be able to contact us to troubleshoot the problem? We would like to make things right in your situation.

Respectfully,


CMUSA Support.
