HA1250H12SB-Z Avalon A13 A15 Fan

HA1250H12SB-Z: reliable Avalon cooling fan selection

HA1250H12SB-Z is a replacement cooling fan for matched Avalon ASIC miner maintenance. This PunkHash listing identifies the hardware by its complete model and installed configuration, helping repair teams choose the required part before arranging a mixed spare-parts order.

HA1250H12SB-Z specifications and applications

How to match the HA1250H12SB-Z

The source describes a dual-interface arrangement with two fan connections on one unit. Match both connector housings, lead lengths and the original fan label; one dual-connector fan is not automatically equivalent to two separate chassis fans.

This 50 mm frame is mechanically different from a 38 mm A1246-style fan. A1566I immersion and A15eHA Hydro configurations are outside this air-cooled replacement listing.

Diagnose cooling before replacing parts

A low fan-speed reading can result from a worn fan, a loose harness, a blocked air path or a controller-side problem. Check the reported fan channel and inspect the connector with power isolated. Dust buildup, damaged guards and reversed airflow can also affect cooling; replacing a fan alone does not establish that the underlying fault is repaired.

HA1250H12SB-Z and related Avalon repair parts

For A1346/A1366 repairs, compare the Avalon A1366 controller family and the PSU3400-03 A13 supply. The controller family also lists model-specific A1466 and A1566 configurations, but the linked PSU page does not establish A1566 compatibility. For an A1566 power-supply order, send its complete original PSU label for separate matching.

Common questions about HA1250H12SB-Z

What should I send to confirm compatibility?

Send the exact miner model, full original part label, clear photographs of all connectors, required quantity and destination country. Add the board revision and cable length where relevant. For a farm with mixed hardware, list each machine variant separately so the quoted part is selected for that configuration.

Can a matching brand name replace a hardware check?

No. Miners within one brand can use different frame sizes, connectors, board platforms and power supplies. Shared model-family names are useful for narrowing the search, but the installed hardware remains the selection reference. Request confirmation of the quoted version before ordering.

How is an international HA1250H12SB-Z order prepared?

PunkHash can review a spare-parts inquiry for mining operators and repair teams in the United States, Mexico, Colombia, the UAE and other destinations. Provide the delivery country and postal code for freight and import planning. Lead time, batch condition, warranty and included items are confirmed in the quotation; they are not inherited from another seller.

Plan a matched HA1250H12SB-Z replacement

Keep the original identification in the maintenance record and verify the repaired miner under monitored operation. For fan work, confirm airflow direction, unobstructed guards, secure cables and a stable speed reading. For controller or PSU work, use the correct machine configuration and a qualified installation process. Send model, quantity and destination to PunkHash for quotation.
