Each fan in this three-pack uses a brass-housed impeller with dual ball bearings, supplies high static pressure and up to 180 m³\/h airflow, and supports PWM or voltage regulation through a standard 4-pin connector. Protective circuits guard the fan against common electrical faults, while the long cable lets you place the fan where it performs best.\u003c\/p\u003e\n\n\u003ch3\u003eHow much cooling performance does the S12038-4K deliver?\u003c\/h3\u003e\n\u003cp\u003eThis fan combines significant static pressure with strong airflow to move air efficiently through dense radiators or tight heatsinks. With a static pressure of 11.45 mmH2O and a peak airflow of 180 m³\/h, it excels where resistance is high.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStatic pressure: 11.45 mmH2O for pushing through radiators and fin stacks.\u003c\/li\u003e\n  \u003cli\u003eMaximum airflow: 180 m³\/h for effective heat dispersion.\u003c\/li\u003e\n  \u003cli\u003e120×38 mm size for higher swept area than typical 25–25 mm fans.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I control fan speed and connect it to different headers?\u003c\/h3\u003e\n\u003cp\u003eYes—speed is adjustable via PWM or voltage, giving you precise regulation across a wide RPM range. The fan uses a standard 4-pin plug but remains compatible with 2-pin and 3-pin headers, so it fits most motherboard or controller setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e4-pin PWM connector for automated motherboard control.\u003c\/li\u003e\n  \u003cli\u003eBackward compatibility with 2-pin and 3-pin headers.\u003c\/li\u003e\n  \u003cli\u003e30 cm cable for flexible routing and placement inside cases or racks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the S12038-4K durable and reliable?\u003c\/h3\u003e\n\u003cp\u003eLongevity is built into the mechanical and electrical design: the impeller is secured in a brass housing with two ball bearings to resist heat, dust, and mechanical wear.
