This DC 12V automatic fan speed controller adopts intelligent temperature sensing design to dynamically adjust fan speed. When the detected temperature rises, it increases fan speed to boost heat dissipation; when temperature drops, it lowers rotation speed to cut down running noise, balancing cooling performance and quiet operation.
It features a maximum output current of 1A, capable of driving multiple case fans, CPU cooling fans and radiator fans at the same time. Compatible with all mainstream 2-pin, 3-pin and 4-pin PWM fans, covering most PC cooling fan specifications on the market.
Comes with a flexible temperature sensor probe, which can be firmly attached to CPU heatsinks, graphics card backplates or internal cabinet walls to capture accurate hardware temperature data. Compact lightweight body saves limited space inside computer cases, easy to fix with double-sided tape or cable ties.
No driver or software installation required, just connect to 12V power supply and link cooling fans for instant automatic temperature control. Ideal accessory for gaming PCs, silent workstations, server chassis and small industrial equipment to reduce idle fan noise and prevent hardware overheating under high load.
