Description
90mm PC CPU & Chassis Cooling Fan (12V DC, 4-Pin PWM) Product Description Keep your computer hardware or electronic enclosures running smoothly with this high-efficiency 90mm DC brushless cooling fan (industrially sized as a standard 9025 frame). This fan acts as a reliable thermal management component, balancing high-static pressure airflow with quiet operation to expel stagnant heat away from critical processors and internal electronics. Equipped with an advanced 4-pin PWM (Pulse Width Modulation) harness, this fan allows your motherboard or smart controller to dynamically adjust its rotational speed based on real-time temperature fluctuations. Built from high-durability, lightweight PBT plastic with a balanced 7-blade impeller, it is optimized for consistent long-term operation without generating excessive vibration. Key Features Standard 90mm Form Factor: Measures exactly 90mm x 90mm x 25mm, making it a perfect fit for a wide range of desktop CPU heatsinks and compact PC chassis exhaust mounts. Dynamic PWM Speed Control: The 4-pin configuration enables automated speed regulation, allowing the system to run whisper-quiet under light loads and ramp up to full cooling power during heavy tasks. 12V DC Brushless Motor: Rated at 12V DC, 0.60A, providing high rotational torque and rapid heat dissipation with minimal power consumption. Compatible Mechanisms & Equipment Because this fan features a universal 12V DC 4-pin layout, it is a standard component used extensively across computing infrastructure, specialized gaming rigs, and custom electronic builds. It is directly compatible with the following mechanisms: Desktop PC Towers & CPU Coolers: Fits perfectly as a replacement fan for mid-tower desktop chassis or compact 90x90x25mm 4-Pin Computer CPU Cooling Fans on Daraz.lk. Power Supplies & Inverters: Swaps easily into the cooling brackets of mid-sized power supply units (PSUs), solar power inverters, and charging stations. Network & Server Enclosures: Ideal for network switch boxes, compact server drawers, and external hard drive arrays requiring continuous airflow. DIY Smart Projects: Frequently utilized in custom setups like automated egg incubators, 3D printer enclosures, or audio amplifier cabinets that utilize a 12V control circuit. 🛠️ Installation Check: Please verify your system’s fan header before purchasing. This fan uses a 4-pin PWM connector block. While it can physically plug into a older 2-pin or 3-pin fan rail, doing so will cause the fan to run continuously at 100% maximum speed, disabling the automatic quiet-speed control feature.
