What causes the fan to be too loud?

Loose screws, dust buildup, or bearing type (sleeve is quiet but wears out; double-ball is durable but louder).

What are the MOQ and lead time?

Minimum Order Quantity is 30 sets. Lead time is one month for both peak and off-season periods.

Is OEM/ODM service available?

Yes, we offer full customization from samples or designs, including insulation resistance and voltage specifications.

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 a resistor, or adjust BIOS curves to keep RPM low.

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

3-pin uses DC voltage control for fixed speeds, while 4-pin uses PWM for automatic, precise, and quieter speed control.

Q:How long does the fan last?

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

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

The motor has a wide tolerance range of 5V-13V, though it might not start below approximately 7V.

Q:Which direction should the fan face?

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