In a hyperscale data center running AI workloads on 40U HP BladeSystem enclosures, integrating the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt ensures consistent airflow at 200 CFM per chassis. This targeted solution maintains inlet temperatures below 25 °C under 90% CPU utilization, reduces hot-spot formation by 35%, and drives a 20% improvement in Power Usage Effectiveness (PUE), enabling 99.99% server uptime and predictable capacity expansion.
When retrofitting a 10 MW cloud hosting facility, deploying the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt across over 1,000 HP ProLiant BLc servers delivered a 15% reduction in fan power draw and a 25% increase in heat-extraction capacity. This upgrade translated into $350 K annual OPEX savings, accelerated rack deployment cycles by 30%, and bolstered SLA compliance with sub-30 msec thermal response times.
Telecom operators deploying micro-data centers at remote tower sites leverage the 517520-B21-HP BLc 6X Active Cool 200 FIO Fan Opt for sealed, dust-resistant cooling under extreme ambient conditions (−20 °C to 55 °C). The robust FIO bearings sustain 200 CFM airflow while cutting service‐call rates by 30% and extending Mean Time Between Failures (MTBF) by 40%, ensuring continuous 4G/5G packet processing and reduced field maintenance.

The HP BLc 6X Active Cool 200 FIO Fan Option is a high-performance, hot-swappable fan module that delivers up to 200 CFM of airflow across six fan bays to optimize cooling in HP BladeSystem c-Class enclosures.
This fan option is fully compatible with HP BladeSystem c7000 and c3000 enclosures, as well as any c-Class chassis that support FIO fan modules.
Simply slide the module into an empty FIO fan slot in a powered-off or hot-swap-allowed c-Class enclosure until it clicks into place; the enclosure auto-detects the fan and adjusts airflow.
Yes. The HP BLc 6X Active Cool 200 FIO Fan Option supports hot-swap operations, allowing you to replace or add fans without powering down the BladeSystem.
Each module delivers up to 200 cubic feet per minute (CFM) of airflow across six high-speed fans, ensuring efficient heat dissipation for densely populated blade servers.
Under typical load, the module operates at approximately 52 dBA, balancing high cooling performance with acceptable sound levels in data-center environments.
The six-fan module draws a maximum of 50 watts under full speed, with dynamic power management reducing consumption during lower thermal loads.
When installed in pairs or with existing FIO fan modules, it provides N+1 redundancy to maintain cooling even if one fan module fails.
HP recommends installing at least four 200 CFM fan modules in a c7000 enclosure and two in a c3000 chassis to achieve proper airflow and redundancy.
The unit measures 6.8 x 1.0 x 7.5 inches (W×H×D) and weighs approximately 0.7 pounds, fitting standard full-height c-Class FIO slots.
It is rated for continuous operation between 10°C and 35°C (50°F to 95°F), meeting common data-center thermal standards.
Yes. The module is certified for UL, CE, FCC Class A and RoHS, ensuring safety and environmental compliance in enterprise installations.
Inspect and clean airways and fan intakes quarterly; the hot-swap design eliminates disassembly, and filter maintenance follows standard HP enclosure guidelines.
The HP BLc 6X Active Cool 200 FIO Fan Option is backed by a one-year limited warranty that covers defects in materials and workmanship.
Check the Onboard Administrator logs for fan-related alerts, reseat the module, verify enclosure firmware is up to date, and replace the fan if errors persist.
You can order this fan option through authorized HP resellers or directly from the HP Parts Store using SKU 517520-B21 for accurate fulfillment.
