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:What causes fan noise and how to fix it?
A:
Noise can be caused by loose screws (check mounting), dust buildup (clean regularly), or bearing type. Sleeve bearings are quiet but wear out; double-ball lasts longer but is louder; hydraulic is a middle ground.
Q:Which direction should the fan face?
A:
Look for arrows on the frame. Front/side is usually intake (cool air in), rear/top is exhaust (hot air out). Tower coolers push air toward the rear exhaust.
Q:What is the difference between 3-pin and 4-pin fans?
A:
3-pin uses DC voltage control for fixed/stepped speeds. 4-pin uses PWM for automatic, precise, and quieter speed control. 4-pin plugs into 3-pin headers but runs at full speed.
Q:How long will the fan last?
A:
Sleeve bearing lasts ~2-3 years. Hydraulic bearing lasts ~4-5 years. Double-ball bearing lasts 5-10 years and tolerates 24/7 operation.
Q:How can I make the fan quieter?
A:
Use rubber pegs instead of metal screws, use an inline resistor or low-noise adapter to drop voltage, or adjust BIOS curves to keep RPM low until temperatures rise.
