Fan Chieftec ZF 140 mm PWM Fan

Chieftec ZF 140 mm PWM is a classic 140 mm case fan aimed at stable and quiet cooling without unnecessary effects. With a maximum of 1200 RPM and noise of only 20.1 dBA, it is a good choice if you are looking for a balance between airflow and acoustics. 56.4 CFM airflow is more than enough for a normal to more serious configuration. The clean black design and standard dimensions allow you to install it in almost any mid or full tower.

What you get
With a size of 140 x 140 x 25 mm, this fan covers standard mounting positions for 140 mm, providing greater airflow compared to 120 mm at lower speeds. The hydraulic bearing offers a longer lifespan and less noise compared to the most budget sleeve solutions, especially under 24/7 operation. Thanks to the 4 PIN PWM connector, you can control the speeds through the motherboard according to the temperature – idle it is almost inaudible, and under load it increases speed only when needed. With 0.28 A and 12 V power supply, the load for the power supply and motherboard is within normal limits for a case fan. Add to that a 24 months warranty, and you get peace of mind for long-term use.

• Standard size 140 x 140 x 25 mm, making it compatible with most cases that support 140 mm fans.
• Maximum 1200 RPM for a good balance between cooling and low noise during everyday use and gaming.
• Airflow of 56.4 CFM, sufficient for effective air exchange in the case in a front intake or top/rear exhaust configuration.
• Low noise level of only 20.1 dBA, suitable for quiet systems and working close to the PC.
• Hydraulic bearing, providing smoother operation, less vibration, and longer life compared to basic bearing solutions.
• 4 PIN PWM connector, allowing automatic speed control through the motherboard according to temperatures.
• Operating voltage 12 V and consumption 0.28 A, completely standard for modern case fans.

Who it is suitable for
It is suitable if you are looking for a quiet 140 mm fan for front or rear position in your case – for gaming, office, or home workstation. It is also a good choice if you want to replace noisy stock fans with something more civilized, but without entering the RGB and premium segment. If you are aiming for extreme airflow and high speeds for heavy overclocking, you may need a more aggressive model.

The combination of 140 mm size, 56.4 CFM airflow, and only 20.1 dBA makes this Chieftec fan a sensible choice for a calm, well-ventilated build. With PWM control and hydraulic bearing, you simply install it, set the curve, and forget it exists.
