AI Server Fan Axial Runout Inspection Solutions

Upgraded Thermal Performance for AI Servers: Fan Axial Runout Inspection

With the rapid development of large AI model training, high-performance computing (HPC), and cloud infrastructure, AI servers are continuously evolving toward higher computing power and unprecedented power consumption. As a critical component ensuring stable server operation, thermal management systems place immense demands on the dimensional accuracy, assembly consistency, and reliability of their moving parts.

Challenge: High-Speed Fan Instability

During the high-speed rotation of server cooling fans, axial runout, the degree to which the fan wobbles along its axis, can cause catastrophic systemic issues. Excessive axial runout adversely affects overall cooling efficiency, generates unacceptable operational noise, and significantly reduces the product lifespan of the fan unit. Traditional tactile measurement tools cannot accurately inspect these components while in dynamic motion.

Solution: SinceVision SG Series Laser Displacement Sensors

To address these critical inspection needs during manufacturing, SinceVision offers advanced, non-contact measurement solutions utilizing our SG Series laser displacement sensors.

The SG Series is engineered to provide high-precision, high-efficiency in-line dimensional inspection for cooling components. By deploying this technology, manufacturers can measure axial runout dynamically while the fan is operating at maximum RPMs.

Core Technical Capabilities:

• 590 kHz High-Speed Sampling: Ultra-fast sampling frequencies allow the sensor to capture minute displacement changes in high-speed rotating targets without data loss or motion blur.

• Micrometer-Level Precision: Achieves an inspection accuracy of up to 5 μm. 

• Non-Contact Detection: Utilizes advanced laser triangulation technology to eliminate mechanical wear on the fan blades during the testing phase.

Solution Advantages

• Supports high-speed, in-line automated inspection.

• Meets the micrometer-level dimensional measurement requirements of next-generation AI hardware.

• Balances extreme inspection accuracy with rapid production cycle times.

• Seamlessly integrates into automated manufacturing and assembly lines.
