EY4A011 ENDORFY Case Fan

Enterprise 140mm PWM chassis cooling fan for stable server airflow with the EY4A011

The EY4A011 is an ENDORFY 140mm PWM case fan engineered as a server component for predictable intake or exhaust airflow in workstation and rackmount chassis. In mixed CPU, GPU, and storage configurations, the EY4A011 supports thermal headroom by maintaining steady air exchange across heat-dense zones such as VRM areas, RAID/HBA regions, and front drive cages.

Designed for standard 12V DC fan platforms, the EY4A011 integrates through a 4-pin PWM header to enable closed-loop speed control from the motherboard or BMC fan curves. This provides an architectural advantage over fixed-speed airflow: it allows cooling to track workload phases, reduce unnecessary acoustic load, and stabilize component temperatures under variable PCIe expansion and storage activity. The 140 x 140 x 25 mm format targets balanced airflow coverage in common fan wall and chassis mount positions while remaining compatible with typical server and workstation mounting patterns.

Why Choose the EY4A011?

The EY4A011 is selected when operational stability depends on consistent, controllable airflow rather than peak RPM. By pairing PWM regulation with a standard 12V ecosystem, the EY4A011 fits cleanly into scalable deployments where identical fan behavior simplifies maintenance, spares strategy, and thermal validation across multiple chassis builds.

ENDORFY focuses on practical mechanical design and dependable electrical integration for enterprise-adjacent environments. The platform alignment of the EY4A011 with standard PWM headers supports modern data centre expectations for predictable fan control, serviceability, and repeatable thermal profiles during hardware lifecycle changes.

Key Applications:

• Server chassis intake and exhaust replacement
• Workstation thermal stabilization for mixed CPU/GPU loads
• Supplemental airflow for storage bays and RAID/HBA zones
• General-purpose datacentre fan wall maintenance
