Fans Delta PFB2048HT 200mm 4800 RPM 4 Pin Server Fan

200 mm Server-Grade Cooling Fan

The Delta PFB2048HT is a 200 mm case fan built for server and high-density chassis. It spins at 4800 RPM and moves 569.5 CFM of air through a 70 mm thick frame. The four-pin connector allows PWM speed control. Ball-bearing construction supports continuous operation in demanding environments.

Suited for High-Airflow Server Builds

This fan targets administrators who need maximum airflow per slot in rackmount or pedestal servers. The 68.5 dBA noise output makes it unsuitable for quiet workstations or home labs where acoustic comfort matters. Buyers who want low-noise cooling or RGB lighting should look at something else.

Sustained Load Airflow Stability

Under constant load the ball bearing maintains the rated 4800 RPM without the wear-related slowdown seen in sleeve designs. The 48 V 2.85 A motor delivers steady torque so airflow remains at 569.5 CFM during extended duty cycles. The thick 70 mm frame resists vibration that can degrade performance over time.
