How do I know if the fan is dying?

Listen for clicking/grinding, check for significantly lower RPM than spec, or test if blades spin freely without wobble.

Can I connect the fan to a power supply?

Yes, connecting to a PSU Molex runs it at 12V full speed, but motherboard headers allow for speed control.

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 RPM via BIOS, or use a low-noise adapter to reduce voltage.

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 auto speed control and quieter, precise 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.

Q:Which direction should the fan face?

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

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

The motor has a wide tolerance (5V-13V) and can run at lower voltages, though it might not start below ~7V.
