Jonsbo has officially introduced the HF3-120 series cooling fans, marking a significant advancement in their product lineup. These fans feature a robust 120x30mm thickened frame design and utilize high-strength liquid crystal polymer (LCP) for both the fan frame and blades. The series is equipped with NMB dual-ball bearings, ensuring extended longevity and stable performance.
Enhanced Stability and Precision Engineering
By leveraging LCP material, Jonsbo has achieved a more rigid fan structure that significantly reduces deformation during high-speed operation. One of the key design highlights is the ultra-narrow 0.5mm clearance between the fan blade tips and the frame. This precision engineering minimizes air leakage, leading to a more concentrated airflow that enhances overall cooling efficiency.
To further optimize performance and durability, the HF3-120 series incorporates integrated silicone shock-absorbing pads at all four corners, effectively dampening vibrations. Additionally, the fan axis is adorned with a CD-shaped concentric circle pattern, contributing to its refined aesthetic and mechanical balance.
Three Variants for Different Applications
Jonsbo offers three variants of the HF3-120 series to cater to diverse cooling requirements:
- HF3-120B (Black) – Standard Edition
- HF3-120W (White) – Standard Edition
- HF3-120HB (Black) – High-Speed Edition
The HF3-120B and HF3-120W, with a maximum rotational speed of 2800 RPM, are ideal for PC cooling applications. Meanwhile, the HF3-120HB pushes the limits with a 4000 RPM maximum speed, making it well-suited for industrial and server environments where high static pressure and airflow are essential.
