Arctic P14 PWM PST 140mm Fan Black/Black - ACFAN00125A

Arctic P14 PWM PST is a 140 mm case fan aimed at stable cooling with controlled speeds and a good balance between airflow and noise. With a size of 140 x 140 x 25 mm and a speed of 200 – 1700 rpm, it is a flexible choice for front intake, top exhaust, or radiators if you prefer 140 mm fans. The black design without RGB is for those who want a clean, unobtrusive look and focus on function. The low noise level of 0.3 Sone makes it particularly suitable if you are aiming for a quiet machine.

What you get: a fan that can spin slowly and almost silently at idle, but can ramp up to 1700 rpm when the CPU and GPU heat up. With an airflow of up to 72.8 CFM (123.76 m³/h) and static pressure of 2.40 mm H₂O, the P14 PWM PST performs well even through denser mesh panels or thicker filters. The dynamic fluid bearing is designed for long life and less vibration, which is key if the machine runs many hours a day. The 4 PIN connector gives you PWM control through the motherboard, allowing you to set your own fan curve. The low consumption of 1.44 W (0.12 A / 12 V) is also a plus if you are filling the case with more fans.

• Size 140 mm – larger blade for more air at lower speeds and less noise compared to 120 mm fans.
• Speed 200 – 1700 rpm – wide range for super quiet mode at idle and aggressive cooling under load, depending on the profile you set.
• Airflow 72.8 CFM / 123.76 m³/h – sufficient for effective cooling of components in mid and high airflow cases.
• Max. pressure 2.40 mm H₂O – suitable for mounting behind dust filters or dense panels where higher static pressure is needed.
• Noise level 0.3 Sone – optimized for quiet operation, so your machine doesn’t sound like a hairdryer during normal use.
• Dynamic fluid bearing – better durability and less noise over time compared to basic sleeve bearings.
• 4 PIN connector and 12 V, 1.44 W consumption – easy integration with PWM headers on the motherboard and minimal load on the power supply.
• Black color without RGB – clean, unobtrusive look for stealth builds or systems without lighting effects.
• Warranty 72 months – long-term peace of mind for a fan that will likely outlast one or two system upgrades.

It is suitable if you are building a quiet gaming or work machine, NAS, or just want to improve the airflow of your case without a disco of RGB. It is also a good choice for more serious configurations with more heat, as long as you have free 140 mm slots. If you are aiming for a fully RGB look, there is no lighting here, and you will need to combine it with other models.

The combination of 140 mm format, serious airflow, and low noise level, plus 6 years warranty, makes Arctic P14 PWM PST a very sensible “set-and-forget” fan for almost any build.
