About the Product
JetFlo 120 is a high performance, long-lasting computer case cooling fan by Cooler Master. The high quality design of JetFlo 120 places emphasis on performance, style, and silence, critical areas of focus for today's DIY computer builders. The blades found on each JetFlo fan are ultra-thin yet extremely strong, enabling minimal resistance while maximizing performance, cutting through air at speeds ranging between 800-2,000 RPM (PWM functions supported). At full operating power, JetFlo is capable of producing up to 95 CFM of airflow. Longevity is a key feature in JetFlo as it utilizes Cooler Master's latest bearing technology, a self-lubricating polyoxymethelene (POM) bearing that allows JetFlo to be nearly dustproof and last up to 160,000 hours. LED equipped versions of JetFlo 120 feature high quality LEDs that spread light evenly, spanning from the motor and creating a more consistent ambiance. Registering in at a maximum of approximately 36 dBA, JetFlo is powerful while remaining extremely quiet thanks to rubber mounting corners that contain threaded steel inserts. These special materials absorb much of the vibrations and noises produced by the fan. If you're looking for some powerful, stylish, and quiet fans for your new rig, look no further as JetFlo is here.
Corsair Air Series LED high airflow PC case fans combine efficient, low-noise airflow with striking LED lighting. The custom-molded blades are designed for high-volume air delivery with less noise and turbulence than typical case fans. They’re translucent, with a frosted texture, so the light from the four LEDs adds a dramatic effect.

What customers say about "Key Specs"
Cooler Master JetFlo 120 High Performance 120mm LED Fan (Blue)
  • Powerful, efficient and more importantly quiet! Highly recommended!
  • At lower RPM's it is not noticeable at all, not more than any standard 120mm fan because it is running at standard 120mm speeds.
  • Move a LOT of air for 50% power. I have had 120mm 100+ CFM fans before and they did not push this much air at 50% and they did not do it so quietly
  • Good for the money, moves some good air, I do really like the LED effect.
  • The fans also rattle a bit, I don't mind some fan noise and typical airflow whine but rattling and grinding sounds really are annoying.
Corsair AF120 Quiet Edition
  • The Fans push some good air through them. I didn't see an overall drop in ambient temperatures, but I had really good airflow before.
  • Superior airflow at any given noise level
  • Good airflow movement. They are not the quietest fans on the market, but I don't really care about that....its just white noise.
  • My only complaint is there is not an arrow showing you the airflow direction that I found but I may have overlooked it. Easily worth 5 stars.
  • I used a pair of these fans to add airflow to a gaming system in a thermaltake case, and these are a good fit, are quiet, and the illumination adds a degree of coolness.

Cooler Master JetFlo 120 High Performance 120mm LED Fan (Blue)
  • Installed 6 of these, including 4 on a radiator for push-pull operation. They were good at moving air in a mid size tower.
  • have the Mid-sized HAF case and i put 3 of these(1 red, 2 white) and a 200mm(red) on the side along with the 200mm in the front.
  • I ordered this fan without even knowing if it was the right size for my case. It literally was delivered the very next day and I can't believe the build quality!
  • It's great to have a big fan in the computer. It is quite too. Quitier than the fan that had been in the computer.
  • I use this as a helper fan for the CPU Cooler, modified case air grill across from CPU and attached there. I meant for this to replace rear exhaust fan but it is to big.
Corsair AF120 Quiet Edition
  • These fans are great fans for cooling down any computer components that you may have. But make sure you get the correct size and make sure it's either a push or pull depending on what you wish to do if you're going to use the cooler unit like a radiator.
  • We picked up 2 of each size of these fans in 2 different sizes (120mm and the 140mm variant, also purple) for a new system build, in a case with a window. While not really a necessity, the lighted fans do add a bit of extra flair.
  • Сorsair is the best at everything!! these fand are great. i bought a Sentey BX-4237 case that has slots for these size fans. the blue light is very bright!! great product
  • Size? ehh, they could be a little thinner but they're not huge.
  • Excellent fans. I have a full size Thermaltake X9 cube running 12 of these. Extremely quiet and good color.

What customers say about "Features"
Cooler Master JetFlo 120 High Performance 120mm LED Fan (Blue)
  • This fan has a GREAT range of speed on it. Very few other fans can match this one as far as how slow and how fast it can run in RPM. Higher RPM = more air flow= cooler temps.
  • Very good-looking cables. The sleeving is fantastic and just puts the cherry on top of a very premium-looking fan.
  • LED placing. I'm really tired of seeing LEDs mounted on the outer frame of fans. The inner mounting looks a lot better.
  • Can be difficult depending on your motherboard to regulate the speed of this fan.
  • The only con I can think of is the 19dB adapter. I was hoping the solution would be a little more clever than just a resistor. But, I'm not using it and it really doesn't affect you if you do use it. Although you definitely should keep the resistor away from heat-sensitive components.
  • Although they seemed decent on the noise floor to start, one of them started the old annoying fan rattle after only a month and a half.
Corsair AF120 Quiet Edition
  • They don't make much noise, and in my case they are automatically speed regulated based on heat.
  • Fan noise is minimal, even at full speed with these fans as well.
  • At full speed they are using only 12V and spin at 1500 RPM, this keeps your system nice and cool and creates great air flow through your system with very low noise level.
  • Included low-voltage adapter for even more quiet operation
  • LED color is a little bit bluer than some others.
  • Speed can't be controlled by some motherboards
