CR-Q4B

High-Performance 140mm PWM Chassis Cooling Fan for Controlled Airflow with the CR-Q4B

The CR-Q4B is a 140 x 140 x 25mm PWM fan engineered for predictable chassis airflow and heatsink fan replacement in workstation and server platforms where thermal stability matters more than peak RPM. CR-Q4B integrates into standard 12V 4-pin headers, enabling closed-loop fan curves via system firmware or BMC policies to align cooling response with real component telemetry.

With a rated speed of 1000 RPM and an acoustics profile specified at 19.5 dBA, CR-Q4B targets deployments that require continuous operation without excessive noise, including edge and branch environments. The 159g fan assembly supports low-vibration mounting, while PWM control helps reduce unnecessary airflow during idle and light-load periods, improving overall system efficiency and reducing recirculation risk in compact chassis layouts.

Why Choose the CR-Q4B?

CR-Q4B provides a pragmatic density-to-performance balance for enterprise enclosures by delivering stable, controllable airflow in a common 140mm footprint that simplifies spares, standardisation, and service workflows. CR-Q4B is well suited for scalable rollouts where consistent fan behaviour, predictable power integration, and reliable operation are required across mixed server and workstation fleets.

Cryorig’s component engineering focuses on mechanical robustness and repeatable thermal performance for long duty cycles, aligning with modern data centre expectations for maintainability and platform compatibility. The CR-Q4B reflects this approach through straightforward 4-pin PWM integration and form-factor adherence that reduces qualification effort during system builds and refresh cycles.

Key Applications:

Workstation and server chassis airflow
Heatsink fan replacement
Edge and branch systems with low-noise targets
Lab and development systems thermal management
