AI-Powered supplier vetting
SummaryThe supplier provides extensive customization options and has a strong research and development capability, including ODM services and new product development. However, they lack overseas warehouse and showroom capabilities, and do not have overseas agents or participate in trade shows. Their financial data is up-to-date and they hold an ISO9001:2015 certification. Despite having quality assurance processes, the manufacturing capacity seems limited with only two production lines and no ongoing volume reconciliation or outsourcing SOPs.

Product Q&A
Q:How can I reduce fan noise?
A:
Use rubber grommets instead of screws, lower RPM via BIOS, or use a low-noise adapter to reduce voltage.
Q:What is the difference between 3-pin and 4-pin fans?
A:
3-pin uses DC voltage control for fixed speeds, while 4-pin uses PWM for automatic, precise speed adjustment by the motherboard.
Q:How long does the fan last?
A:
Sleeve bearings last 2-3 years, hydraulic bearings 4-5 years, and double-ball bearings 5-10 years under 24/7 use.
Q:Why does the fan spin at 5V if labeled 12V?
A:
The motor has a wide tolerance (5V-13V), though it may not start below ~7V. It runs at full speed on 12V PSU.
Q:How do I know the fan is failing?
A:
Listen for clicking/grinding, check RPM via software for drops below spec, or check for wobble/stiffness when spinning manually.
