The Quietest 140mm Case Fan of 2018

Updated December 10th, 2018 by Headshot Jacob Tuwiner

After testing more than 8 fans, we’ve concluded that the Corsair Air Series AF140 Quiet Edition (QE) is the best 140mm case fan for your money in 2018.

140mm case fans are capable of pushing more air than smaller case fans when spinning at the same speed thanks to their blades’ greater surface area.

Although some small cases are not capable of housing large 140mm case fans, if you have an ATX case, it’s more than likely compatible.

Otherwise, if you’re using a smaller Micro-ATX or Mini-ITX case, you may want to consider a 120mm case fan or, smaller still, an 80mm case fan.

The Corsair AF140 QE delivers high airflow while remaining quiet and efficient. This low-noise case fan has striking LED lights and translucent blades with a frosted texture, resulting in a stunning lighting effect during operation. It’s the perfect compliment to any gaming setup.

You can buy this fan with red, blue, white, or purple LEDs. In adition, the fan ships with two interchangeable rings for a total of three – you can choose between red, white, or blue.

As far as performance is concerned, the AF140 QE cooling capability is exemplary. The fan needs at least 3cm of mounting clearance, and performs best when used as an exhaust fan, mounted near the rear or the top of your case. Likewise, they can also be used as intake fans mounted near the side panel or bottom air intakes.

AF stands for airflow, meaning these fans perform their best when operating as intake or exhaust fans, rather than being used in tight spaces. They’re optimized for airflow, not static pressure. If you’re interested in cooling highly obstructed areas such as hard drive cages or other tight spaces, you’re better off purchasing a fan with high static pressure as opposed to high airflow.

The AF140 outperforms other standard 140mm case fans, as the blades are custom-molded for optimal airflow and performance. The blades are also ultra-thin to reduce noise, and lastly, the sleeve bearing coupled with the fan’s padded corners work together to minimize vibration noise.

Also inside the box you’ll find a bag containing a set of four screws to mount the case fan, in addition to a step-down resistor used to underpower the fan, decreasing the voltage from 12V to 7V.
