Short multicoloured cable with a 5.25 inch Molex plug splitting into four 3-pin fan sockets

Vszerda

Vszerda 6 inch Molex 4-pin to 4× TX3 3-pin fan adapter cable, 2×12V/2×5V, speed reduction, 20AWG

SKU CH-4N4F-DP9GJ

Connects four 3-pin TX3 fans to one 5.25" Molex 4-pin LP4 connector, supplying two fans at 12 V DC and two at 5 V DC with speed reduction on the 5 V pair using 20 AWG UL1007 wire

  • Connects four 3-pin fans to one Molex connector
  • Two fans run at 12V and two at 5V DC
  • Speed reduction lowers noise on two fan headers
  • 20AWG UL1007 tinned copper wire ensures reliable power delivery
  • Short 6-inch length keeps cable routing tidy inside the case

Connect four fans from one Molex connector

This adapter splits a single 5.25 inch Molex LP4 male connector into four TX3 3-pin female headers. Two headers supply 12 V DC and two supply 5 V DC, allowing mixed voltage fan operation from one power supply lead.

Two fans run at reduced speed

The 5 V DC headers lower the voltage to those fans, cutting noise and airflow compared with the 12 V headers. All four connectors carry only power and ground wires, so no tachometer signal reaches the motherboard and fan speed cannot be monitored.

Short 6 inch cable with 20AWG UL1007 wire

The 6 inch length keeps routing tidy inside cramped cases but limits placement options for distant fan mounts. Missing tachometer pins mean the motherboard will report zero RPM for connected fans, which may trigger BIOS warnings on some boards.

Questions about this item

Do the 3-pin fan headers on this adapter include a tachometer wire for speed monitoring?

No, each TX3 connector uses only two wires so the tachometer pin is absent and the motherboard cannot read fan RPM.

What is the combined current limit of the single Molex LP4 connector supplying all four fans?

The adapter draws power from one 5.25-inch Molex 4-pin LP4 male connector, so total fan current must stay within that connector's rating.

Will the 20AWG wires and 6-inch length add noticeable heat or voltage drop when all four fans run continuously?

The 20AWG tinned-copper UL1007 wire and short 6-inch runs keep resistance low, so heat and voltage drop remain minimal under typical fan loads.
