How do I know if the fan is failing?

Listen for clicking or grinding noises, check if RPM is significantly lower than specified using monitoring software, or check for blade wobble.

Can I connect the fan to the power supply?

Yes, connecting to a PSU Molex runs the fan at 12V full speed. However, motherboard headers allow for speed control, which is preferred for 4-pin PWM fans.

What is the minimum order quantity?

The minimum order quantity is 30 sets.

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?

Use rubber grommets instead of screws, lower voltage with an inline resistor, or adjust the BIOS fan curve to keep RPM low until temperatures rise.

Q:What is the difference between 3-pin and 4-pin fans?

3-pin fans use DC voltage control for fixed or stepped speeds. 4-pin fans use PWM for automatic, precise speed control, resulting in quieter operation.

Q:How long does the fan last?

Sleeve bearings last 2-3 years, hydraulic bearings 4-5 years, and double-ball bearings 5-10 years, depending on usage conditions.

Q:Which direction should the fan face?

Follow the arrows on the frame: intake arrows point to cool air in (front/side), and exhaust arrows point to hot air out (rear/top).

Q:Why does the fan spin at 5V if labeled 12V?

The motor has a wide voltage tolerance (5V-13V). It may not start below ~7V but can spin at lower voltages.
