ID-COOLING AT-120-K 120mm High Static Pressure Fan, 5.04mmH2O, Dual Ball Bearing, Closed-Loop Motor, Rectifying Ring Blade, Smart 0RPM Mode, Performance PC Cooling Fan

【5.04mmH₂O High Static Pressure – Built for Radiators】 Delivers powerful 5.04mmH₂O static pressure, ideal for liquid cooling radiators, tower heatsinks, and dust-filtered cases where airflow resistance is high. 【Dual Ball Bearing – Long-Lasting & Heat Resistant】 Premium dual ball bearing design provides extended lifespan, improved heat tolerance, and stable performance during high-speed operation. 【Closed-Loop Motor – Consistent Airflow Output】 Automatically adjusts electrical input to maintain stable RPM under resistance. Prevents airflow drop-off and ensures reliable cooling performance. 【Rectifying Ring Blade – Focused Vertical Airflow】 Ring-structured blade channels air vertically in a concentrated stream, reducing turbulence and preventing airflow diffusion for more efficient heat removal. 【Smart 0RPM Mode – Silent at Low Load】 Fan stops spinning when temperatures are low, delivering zero-noise operation during idle. Activates automatically when cooling is needed.
