Zyvpee DBTB0838B2S 80mm case fan 12V 2.1A 4-wire 7000 RPM 80 CFM 50 dBA 80x76mm

Zyvpee DBTB0838B2S server fan

The Zyvpee DBTB0838B2S is an 80 mm axial fan built for server and workstation chassis that demand high static pressure. It targets system integrators and IT professionals who need reliable thermal dissipation in dense 1U or blade enclosures where standard low-speed fans cannot move enough air. The 4-wire PWM connector allows the motherboard or fan controller to regulate speed automatically based on sensor data. Its black frame and non-LED design keep the appearance neutral for professional rack environments.

12 V 2.1 A 4-wire integration

The fan draws 2.1 A at 12 V, so the header or fan controller must supply at least that current without voltage drop. Four-wire PWM control frees the builder from manual voltage adapters and lets the system balance acoustics against thermals in real time. The 80 mm by 76 mm frame fits standard 80 mm mounting holes, making it a direct drop-in replacement for OEM server fans of the same footprint. No additional brackets or converters are required when the chassis already provides 4-pin headers spaced for this pitch.

7000 RPM 80 CFM headroom

At speeds above 7000 RPM the fan pushes more than 80 CFM, giving ample headroom for multi-core CPUs, GPU clusters or high-density storage arrays that generate concentrated heat loads. The dual ball bearing is rated for continuous operation at this velocity, reducing the risk of bearing wear compared with sleeve designs. Acoustic output exceeds 50 dBA at full speed, so the unit is unsuitable for quiet office or home-theatre builds where low noise is a priority. Buyers who need silent operation or larger frame sizes should look elsewhere.
