How do I know if the fan is failing?

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, using a PSU Molex connector 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 demonstrates strong customization, R&D, OEM/ODM, quality-control, and complaint-handling capabilities. It reports new products within the past year, provides customization from samples and designs through full customization, and serves known brands through OEM. Production includes two lines, inventory capability, defined inspection procedures, and four QA/QC inspectors. However, important operational limitations exist: no available SDK, no overseas agents, branches, warehouse, or showroom, no offline trade-show participation, and only one experienced export-trade employee. Manufacturing controls also show gaps, including no ongoing quantity reconciliation for each batch and no standard operating procedure for outsourced manufacturing. Financial evidence is represented only by years rather than substantive indicators, so credibility cannot be determined. The supplier holds an ISO9001:2015 certificate, but the available information does not establish broader certification coverage.

Supplier typeThe supplier operates as a manufacturer with two production lines, provides OEM and ODM services, offers inventory capability, and accepts FOB and EXW quotations. It also provides full customization, but lacks overseas agents, branches, warehouses, and showrooms.

CertificationsThe supplier reports an ISO9001:2015 certificate. No additional specific certifications are identified in the provided information.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints and corrective/preventive actions, supporting an established service-response process. However, it has no overseas agents, branches, warehouse, or showroom, which limits demonstrated overseas service infrastructure.

R&D capabilityThe supplier reports new products in the past year, provides ODM services, and assigns R&D personnel to product development, design drawings, production support, and specifications. Nevertheless, it has no available SDK and no design input, output, review, validation, or confirmation documents available for audit.

Production capacityProduction evidence includes two production lines, inventory capability, one-month average lead times in both peak and off-season periods, four QA/QC inspectors, written finished-product inspection instructions, and multiple listed production machines. Controls are weakened by the absence of ongoing batch quantity reconciliation and a standard operating procedure for outsourced manufacturing.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, and full customization, with the same capability reported under both R&D and design services. This directly demonstrates broad customization coverage.
