Manufacturer description
The Noctua NF-A14 iPPC-2000 PWM is a heavy-duty 140mm cooling fan built for systems where airflow and durability matter more than silence. It is the high-speed industrialPPC version of Noctua's award-winning A-series 140x25mm fan, so it spins up to 2000 RPM for radiators, dense server racks, workshop PCs, and enclosures that run hot around the clock. Its 4-pin PWM connector lets your motherboard or fan controller scale speed automatically across a 500-2000 RPM range. That means near-idle operation at light load and full airflow when temperatures climb. At maximum speed the fan is rated at…

Frequently Asked Questions
How fast does the Noctua NF-A14 iPPC-2000 PWM spin?
It runs from 500 to 2000 RPM. The 4-pin PWM connector lets a compatible fan header adjust the speed automatically within that range.
How loud is the NF-A14 iPPC-2000 at full speed?
Noctua rates it at a maximum of 31.5 dB(A) at 2000 RPM. With PWM control, it runs slower and quieter when your system is under light load.
What does the IP52 rating mean for this fan?
IP52 means limited protection against dust ingress and protection against dripping water. Combined with the fibre-glass reinforced polyamide frame, it suits dusty or humid industrial settings, but it is not designed for submersion or direct water jets.
What size is this fan and will it fit my case or radiator?
It measures 140x140x25 mm and runs on 12V. It fits any standard 140mm fan mount or 140mm radiator. It will not mount in 120mm-only positions.
What warranty does the Noctua NF-A14 iPPC-2000 come with?
The fan is rated for more than 150,000 hours MTTF. For current warranty terms, check the product listing or Noctua's official website.
