NZXT F140 Q 140mm PWM Fan

The NZXT F140 Q is a 140mm case fan built for quiet, high-volume airflow in standard mounting points. Its nine sickle-style blades and chamfered frame concentrate air for effective intake or exhaust cooling without LED lighting.

Check 140mm Mount and 4-Pin Header

Verify your chassis has a 140mm fan slot and that your motherboard or fan controller offers a 4-pin PWM header for speed control. The fan is 25mm thick, so confirm clearance against side panels or cable routing before ordering.

29.8 dBA at 1500 RPM with Fluid Bearing

At full speed the fan reaches 1500 RPM and delivers 102.90 CFM at 1.77 mm H2O while producing 29.8 dBA. The fluid dynamic bearing and PWM curve keep noise low during typical loads, and the 500 RPM minimum allows near-silent idle operation.

Questions about this item

What comes in the box with the RF-Q14SF-B2 and do I need extra screws or cables?

The box contains one 140mm PWM fan with a 4-pin connector attached. Standard case mounting screws are not included, so use the screws supplied with your case.

Should I choose the 140mm model or a 120mm version for my build?

This fan is 140mm wide and 25mm thick. Pick it when your case has 140mm mounting points; a 120mm fan will not fit those holes.

What does the 102.90 CFM airflow rating mean once the fan is installed?

At full speed the fan moves 102.90 CFM with 1.77 mm H2O static pressure, delivering strong airflow through radiators or restrictive meshes while staying at 29.8 dBA.
