2pcs DC12V PWM Fan Controller - 4-Wire Temperature Control Module With Thermistor

About This Product

PC builders and cooling enthusiasts, this PWM fan controller gives you serious control over your system's temperature! This 2-pack of DC12V 4-wire controllers supports Intel's standardized four-wire fan protocol, meaning it works with virtually all standard four-wire chassis fans and CPU fans. The compact 2.0x1.7x0.5 inch board packs impressive features - it can handle up to 5A per output channel with a total bus current of 9A, giving you plenty of power for multiple fans. The temperature control is where this really shines: it comes with NTC 3950 thermistors that sense temperature and automatically adjust fan speeds across four different temperature zones. When temperatures get too high, the built-in buzzer alerts you before components overheat. You get both automatic temperature control and manual speed control options, plus three-way independent control for different functions. The stall detection alarm feature monitors your fans and alerts you if any stop working properly. Each controller can manage up to four 12V fans simultaneously, making it perfect for custom PC builds, server cabinets, or any application needing precise thermal management. The included cables and probes make installation straightforward. Whether you're building a quiet office PC or an overclocked gaming rig, these controllers give you the granular control you need to balance cooling performance with noise levels perfectly. The quality construction ensures reliable operation, and having two controllers means you can set up multiple zones or keep a spare on hand.
