It shares the same 40×40×28mm dimensions and 4-pin PWM connector, making it a plug-and-play replacement for compatible server and networking equipment.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the 4-pin PWM connector do compared to a standard 3-pin fan?\u003c\/h4\u003e\n\u003cp\u003eA: The 4-pin PWM (Pulse Width Modulation) connector allows the motherboard or server controller to automatically adjust fan speed based on system temperature. This results in quieter operation at lower loads and maximum cooling performance when needed — unlike 3-pin fans that run at a fixed speed.\u003c\/p\u003e\n\u003ch4\u003eQ: Why choose a dual ball bearing fan over a sleeve bearing fan?\u003c\/h4\u003e\n\u003cp\u003eA: Dual ball bearing fans offer significantly longer operational lifespans, better performance at higher temperatures, and consistent airflow even when mounted horizontally or vertically. They are the preferred choice for 24\/7 server and datacenter environments where reliability is critical.\u003c\/p\u003e\n\u003ch4\u003eQ: What is included in the package?\u003c\/h4\u003e\n\u003cp\u003eA: Each order includes 1 × 40mm PWM cooling fan.
