Case cooling is becoming more essential These days. Quality fans with better airflow inside your chassis will give you a more stable system. The sickleflow 120 with 2000 rpm is no doubt one of the best case fans in the market.

+One of the best performing Static Pressure fans in the 120mm fan size, and especially at this price
+Nice bright green LED's
+Great fan blade design permits low RPM with very good performance allowing for quieter use
-Made in China
-Sleeve bearing, which does not have the life expectancy of more expensive fans
=120mm x 120mm x 25mm
=3-pin DC-fan (vs 4-pin PWM), therefore LED brightness adjusts with the voltage provided (lower voltage = slower fan speed = dimmer LEDs)
=50,000 hour MTBF Sleeve Bearing (ball bearing is better)
=Max speed: 2,000 RPM
=Max airflow: 69.69 CFM or 118.3 m^3/h
=Max air pressure: 2.94 mm of H2O
=Max noise: 19 dBA
=Max power draw: 4.2W (0.35A)
This fan is designed to best function where there are objects within 3", such as a radiator grill, heatsink or hard drive cage(s). It will not throw air far into a larger case. It will however force air into small crevices (or pull through them) with a much greater success than fans with fewer blades and/or large gaps in the blade design.
Two of these are cooling my processor mounted on a Corsair H100i GTX Extreme radiator (240mm long). I only have to keep them at 1080RPM @ 5.6V for excellent thermal performance
If you want a fan for pushing air through a case, then an Air Flow Fan design would benefit you. Those have higher CFM (cubic feet per minute) values than this fan
I had ordered a couple of the more expensive usb powered AC Infinity MULTIFAN S4, and those things were very quite. But I could not use them because of their USB power source does match my application., so I tried these, but the difference in noise was so significant Im going back to the drawing board. If you are trying to avoid noise these "Cool Masters" are not for you.

If plugged straight into the PSU supply line, it would run at max speed, making a noise which is quite audible in a silent room.
However I realised this could be fitted in the 4 pin motherboard socket for front and rear fans on my Intel motherboard....and that made it 5 times quieter though it doesn’t run controlled by the system still. Perhaps the board voltage/amperage is modest as compared to direct PSU line.
LED effect is good... n I got a quiet pc for just a few bucks...Worth the price totally...
Amazon - perfect as usual in price and delivery!
Not fussed about the LEDs but they are a nice addition, although the fan actually dropped my tempreture of the whole system very significantly, my system is now a lot quieter and cooler. My processor fan doesnt have to work overtime and make a horrible noise due to this brilliant addition. The fan fitted nicely in my Galaxy 3 Tower case and is being powered by one of the many sets of cables you get with the VS550 80 plus power supply.
Brilliant product for such a low price
It's still a 5* product because it's capable of low / moderate speed = silent / quiet and shifting a good amount of air, equally if you're already hard of hearing you can run at full blast and expect small furry animals to run for the hills fearing they may get sucked into it's path.
This and the 212 came early so im not gonna mount them and waste thermal paste but it has cooled down the inside of my case by a lot so its impacted my slightly overclocked graphics card.
Very good quality product you can tell when you hold it in your hand the quality of the build.
Good buy i reccomend this product expecially with the coolermaster hyper 212 evo.
3 pin connection, with included 3 pin to molex through adapter
After installing them and connected them to the motherboard they did run at max speed untill I used the tuning software now they run perfectly keeping a good amount of air moving.
100% Recommend these fans!
