This adapter cable powers 4-pin and 3-pin PC case fans from any USB Type A port at full 12V speed. A voltage step-up circuit built into the USB housing converts the standard 5V USB output to 12V, allowing fans to run at their rated RPM instead of the reduced speed they'd experience at 5V.The 24-inch cable uses 22 AWG wire with black sleeving and terminates in a standard male 4-pin fan connector. Compatible with both PWM and voltage-controlled fans, though PWM control is not available through USB. RoHS compliant.Note: USB ports typically supply limited current. This cable is rated for fans drawing up to 0.40A at 12V. Check your fan's amperage rating before use to avoid overloading the USB port. Show more
