12V Step-Up USB Fan Power Adapter Cable, 24 Inch (60cm) Black Sleeved Wire, Full Speed Fan Power Cord for 3-Pin & 4-Pin PC Cooling Fans

This 12V step-up USB fan power cable is specially engineered to power standard 12V PC cooling fans using common 5V USB power sources. It boosts USB 5V voltage up to steady 12V, enabling your computer fan to run at full rated speed and deliver maximum airflow without speed limitation.

The cable supports both 3-Pin and 4-Pin PWM cooling fans, covering most conventional chassis fans, radiator fans and auxiliary ventilation fans on the market. It offers a convenient power solution when you need to add extra fans but run out of motherboard fan headers.

Measuring 24 inches / 60 centimeters and wrapped in black sleeving, the wire achieves neat layout aesthetics while protecting internal conductors from abrasion. The moderate length provides enough routing space for PC cases, mini ITX builds, electronic equipment cabinets and custom DIY cooling setups.

Built-in stable voltage boost circuit ensures consistent output voltage during continuous operation. It maintains reliable fan rotation and avoids stalling or uneven fan speed. No complicated software or driver setup is required; simply plug the USB connector into a USB power supply and connect the fan terminal to start operation.

Perfect for auxiliary chassis cooling, home server ventilation, DIY electronics, media cabinet heat dissipation and retro computer upgrades. Please verify the power consumption of your cooling fan before use to avoid overloading the USB power supply. This sleeved USB step-up fan cable is a cost-effective choice for hobbyists looking to expand their cooling system.
