4-Pin Molex to 3-Pin Fan Adapter

This adapter converts a standard 4-pin Molex connector into a 3-pin fan header. It allows a 3-pin case or CPU fan to draw power directly from a power supply Molex lead. The cable is intended for builders who need to add cooling fans when motherboard headers are full or absent.

Dual-Voltage 12 V and 5 V Operation

The adapter provides two 12 V and two 5 V lines so the connected fan can run at full speed or at a reduced voltage for quieter operation. It is not suited for 4-pin PWM fans that require a dedicated speed-control signal from the motherboard. Users needing automatic fan curves should use a motherboard header instead.

Questions about this item

How much extra heat does the Molex-to-3-pin adapter add when fans run all day?

The adapter is a passive cable with no active electronics, so it adds no measurable heat during continuous operation.

What power connector must my power supply have to use this adapter?

Your power supply needs a standard 4-pin Molex output to plug the adapter into.
