What should I do if the fan is too loud?

Check for loose screws causing vibration, remove dust buildup, lower the RPM via BIOS, or consider replacing sleeve bearings with hydraulic or double-ball bearings.

Is OEM/ODM service available?

Yes, we provide full customization services including OEM and ODM, allowing customization from samples or designs to meet specific customer needs.

What are the main markets and certifications?

Our products are certified with ISO9001, CE, RoHS, and FCC. Main markets include Europe, the US, South Korea, Japan, Russia, and Ukraine.

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.

Product Q&A

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

3-pin uses DC voltage control for fixed or stepped speeds. 4-pin uses PWM for auto speed control, offering quieter and more precise operation. A 4-pin fan on a 3-pin header runs at full speed.

Q:How long does the fan last?

Lifespan depends on the bearing type: Sleeve bearings last ~2-3 years, hydraulic bearings ~4-5 years, and double-ball bearings can last 5-10 years with 24/7 tolerance.

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

The motor has a wide voltage tolerance, operating effectively between 5V and 13V. It might not start below ~7V, but it can spin at lower voltages.

Q:How can I make the fan quieter?

Use rubber pegs or grommets to reduce vibration, use a low-noise adapter to lower voltage, or adjust the BIOS fan curve to keep RPM low until temperatures rise.

Q:Which direction should the fan face?

Look for arrows on the frame. Generally, front/side fans are for intake (cool air in), and rear/top fans are for exhaust (hot air out).
