Description
ARCTIC S8038-10K PWM 80mm High Performance 4 Pack Server Fans
ACFAN00291A
The ARCTIC S8038-10K PWM (ACFAN00291A) is a bundle of four high-performance 80 mm PWM fans designed for cooling scenarios where space is limited but air movement needs to be strong — such as server racks, 2U chassis, compact PCs, radiator positions, or densely packed component zones.
Each fan in this 4-pack features a wide PWM-regulated speed range from 800 RPM up to 10 000 RPM, giving you the flexibility to run quietly at lower speeds or push large volumes of air when temperatures climb. This adaptability makes the pack suitable for both quiet cooling needs and aggressive thermal challenges.
With ~85.3 CFM of airflow and around 16 mm H₂O static pressure, these fans generate strong directional airflow that performs well even through airflow resistance such as dust filters, radiator fins, or heatsinks. The dual ball bearing design adds mechanical stability and longevity, especially for systems that operate continuously.
This fan pack is ideal for builders and system integrators who need reliable, scalable cooling for blades, servers, and other hardware where 80 mm fans are standard, but strong performance is still essential.
Why It’s a Great Choice
Flexible Cooling Control:
With a wide PWM range (800 – 10 000 RPM), these fans dynamically balance airflow and noise — providing quiet operation during normal conditions and powerful air movement when temperatures rise.
High Airflow & Static Pressure:
Rated at ~85.3 CFM and ~16 mm H₂O, these fans can push air effectively through dense filters, radiators, and restrictive system pathways — excellent for server and compact PC cooling.
Durable Continuous Operation:
The dual ball bearing system enhances reliability and mechanical lifespan, making this fan pack suitable for systems that run 24/7, including servers, industrial systems, or performance builds.
PWM Precision:
4-pin PWM allows automatic motherboard or controller regulation of fan speed, giving balanced performance and acoustics based on workload.
Versatile Multi-Use Pack:
As a 4-pack, it’s ideal for multi-fan HVAC jobs like large server chassis, multiple radiator positions, or synchronous airflow roles throughout a system.
Long Warranty Confidence:
ARCTIC’s 6-year warranty ensures peace of mind and reliability for high-performance continuous operation.
