For an inverter cooling fan replacement, start with the equipment's specified fan and the complete model on the original label. Similar frame sizes or a shared brand do not establish compatibility.

Cooling and fit checks

• Model and dimensions: record the full suffix, frame thickness, mounting holes and cable exit.
• Electrical supply: match the stated AC or DC input, voltage and relevant frequency. Do not assume one model accepts both AC and DC.
• Airflow requirement: compare exact-model performance data against the inverter's cooling path and specification.
• Noise and bearing information: use the selected model's documented values and conditions rather than a blanket brand claim.
• Connection: compare the connector, wire count, lead length and documented pinout.
• Approvals: confirm the required records for the exact model where the equipment specification calls for them.

Signal functions depend on the exact model

A fan or inverter may use speed feedback, alarm, PWM control or a separate start/stop function. Confirm which functions the original equipment expects and the electrical interface for each. Wire count and colour alone do not establish those functions.

A PWM input allows a compatible controller to command speed; it does not by itself prove that the fan senses temperature. Consult the equipment's control documentation and the connector guide.

SXDOOL product references and sourcing

SXDOOL is used here as a product-brand reference. CoolingFanStore is operated by Guangzhou Yougu Electronic Technology Co., Ltd. (广州幽谷电子科技有限公司).

If an SXDOOL-labelled model is proposed, review its exact specifications and connection against the original fan. Do not substitute a PC case fan solely because it shares the mounting width.

For a replacement, use Photo Support with the full label, connector and mounting photos. For quantities or sourcing requirements, request a bulk quote; availability, pricing, included parts and lead time are confirmed for the specific request.
