Extension Cable for PWM Fans

The Silverstone SST-CPF03 is a 300mm PWM fan power extension cable sold in a two-pack. It connects directly to a 4-pin PWM or 3-pin fan header on a motherboard or controller. The one-to-one design adds length without splitting the signal. Builders working in large chassis or routing cables behind motherboard trays use it to reach distant fan mounts.

Length and Connector Limits

At 300mm the cable extends a fan lead by roughly 30cm, which suits most full-tower and mid-tower layouts. It carries the PWM control signal and power on the same four conductors, so fan speed regulation remains intact. The 3-pin compatibility allows voltage-controlled fans to run, though PWM speed reporting is only available on 4-pin headers. Daisy-chaining multiple cables is not supported by the one-to-one design.

Sleeved Build and Daily Use

Each cable is wrapped in a black sleeved jacket that resists abrasion and keeps the bundle tidy behind the motherboard tray. The connectors seat firmly on standard 4-pin and 3-pin headers without blocking adjacent ports. The flexible sleeving bends cleanly around tight corners, reducing strain on the fan header during installation or future upgrades.

Questions about this item

Should I buy the two-pack or look for a single cable?

The product is sold as a two-pack containing two 300mm extension cables, so you receive both in one purchase.

Will the 300mm length reach my rear exhaust fan from the motherboard header?

At 300mm (11.81 in.) the cable adds roughly 30 cm of reach, enough for most mid-tower rear or top fan placements.

Does the 4-pin PWM connector work with my 3-pin fan header?

Yes, the terminal is compatible with both 4-pin PWM and 3-pin fan connectors, so it fits either header type.
