CPU & GPU Fan Set for Acer Predator Helios Neo 16

This set contains one CPU cooling fan and one GPU cooling fan designed as direct replacements for the Acer Predator Helios Neo 16 500 series. Both units operate at 12V 1A and connect via a 4-PIN power connector. The package includes both fans needed to service the laptop's thermal assembly.

Fits PHN16-71, PHN18-71 and N22Q22 series

The fans match part numbers FQ1H, DFSCL12E16486M and 23.QLTN7.001 for the GPU side, plus FQ1J, DFSCK22D05883M and 23.QLTN7.002 for the CPU side. Owners of other Acer models or different laptop brands cannot use this kit. Buyers needing a single fan only should look elsewhere.

4-PIN 12V 1A power specification

Each fan draws 1A at 12V DC through a standard 4-PIN connector, ensuring the correct PWM control and power delivery for the original thermal solution. Verify that the motherboard headers on your unit match this voltage and pin layout before ordering.

Questions about this item

What does the 12V 1A rating mean once the fans are installed in my laptop?

Each fan draws up to 1 amp at 12 volts, so the pair will not exceed the motherboard header's current limit under full load.

What does the 4-pin connector cap in practice for speed control?

The 4-pin PWM header lets the system vary fan speed precisely from minimum to maximum RPM based on CPU and GPU temperature curves.

Will the two fans fit the PHN16-71 and PHN18-71 chassis without modification?

Yes, the set matches the original CPU fan (FQ1J) and GPU fan (FQ1H) part numbers used in those models, so they mount directly to the existing screw holes and heatsink brackets.
