Description
ARCTIC S40-28 6K PWM 40mm High-Speed Server Fan
ACFAN00185A
The ARCTIC S40-28 6K PWM (ACFAN00185A) is an ultra-compact, high-speed cooling fan designed for systems and devices where space is extremely limited — such as 1U server cases, routers, NAS units, DVRs, mini-PCs, HTPCs, HDD enclosures, and 3D printers.
Despite its small 40 mm frame, this fan delivers impressive airflow and static pressure, thanks to its capability to spin up to 6000 RPM under PWM control. The dual ball bearing and robust mechanical design ensure durability and stable performance even in continuous-operation environments.
Its 4-pin PWM interface provides flexible speed regulation, allowing the fan to adapt from low-noise operation during light workloads to maximum performance when needed. Whether you’re replacing a server exhaust fan or adding airflow to compact enclosures, this fan offers dependable cooling in tight space applications.
Why It’s a Great Choice
Super-Compact Cooling:
Ideal for very small spaces (40 mm fans), perfect for 1U servers, mini PCs, DVRs, HTPCs, and other enclosures where standard fans won’t fit.
High Max Speed:
With a maximum of 6000 RPM under PWM control, this fan delivers strong airflow and static pressure — excellent for pushing air through tight or restricted pathways.
Balanced Performance & Noise:
PWM speed control lets the fan scale its performance with system temperature: quiet at low loads and active when needed, giving a versatile balance of acoustics and airflow.
Durable Build:
The dual ball bearing design improves longevity and performance stability, making it suitable for continuous 24/7 operation environments.
Versatile Application:
Beyond server systems, it’s great for routers, NAS, DVRs, mini PCs, HDD enclosures, and 3D printers — wherever compact forced airflow is needed.
Long Warranty Confidence:
A 6-year manufacturer warranty reflects ARCTIC’s confidence in its reliability and build quality — giving peace of mind for long-term operation.
