Defendwe PH2.0 4Pin to Dual 3Pin/4Pin Fan Cable 12cm

SKU CH-9B5H-VWYQR

PH2.0 4-pin adapter splits one graphics-card header into two 3-pin or 4-pin fan connectors using 12 cm of 26 AWG PVC cable

  • Connector TypeMicro USB to USB A
  • Connect two fans to one graphics-card header via PH2.0 4-pin to dual 3-pin/4-pin adapter
  • 12 cm length fits tight GPU clearances without excess cable slack
  • Tin-plated copper conductors on 1007 26 AWG wire deliver reliable power transfer
  • PVC jacket protects the 2.0 mm pitch connectors during installation and routing
  • Enables standard motherboard fans on graphics cards that only offer a small 4-pin header

Graphics card fan adapter

This 12 cm cable connects two standard 3-pin or 4-pin fans to a single graphics card PH2.0 4-pin header. It lets builders run ordinary case fans from the GPU fan controller instead of the motherboard. The adapter solves the physical mismatch between the small GPU connector and larger motherboard-style fan plugs.

PWM control limited to one header

Both attached fans receive the same PWM signal because the graphics card exposes only one control line. Individual speed curves for each fan are not possible with this wiring. The 26 AWG conductors carry power for two fans, so total current draw must stay within the header rating.

Replaces improvised splices or single-fan use

The cable replaces hand-soldered Y-splitters or the need to leave one fan unconnected. The jump is worth it when a graphics card has a single PH2.0 header but the cooling plan calls for dual fans on a heatsink or shroud. Builders who need independent fan curves or more than two fans cannot use this adapter.

Questions about this item

Should I pick the 12 cm cable or a longer one for my build?

The cable is 12 cm long; choose a longer cable only if the graphics card header is farther from the fans.

What does the 26 AWG wire mean for power delivery to two fans?

26 AWG tin-plated copper conductors carry the PWM signal and power from the graphics card to both fans without significant voltage drop over 12 cm.

How does the PH2.0 4-pin connector limit fan control compared to a standard motherboard header?

The PH2.0 4-pin plug fits the graphics card fan header, passing its PWM signal to the dual 3-pin/4-pin sockets so both fans follow the GPU curve.
