Frequently Asked Questions
What is Delta Electronics BFB1012SHA01?
BFB1012SHA01 is a Delta Electronics DC brushless centrifugal blower commonly sold as a graphics card cooling fan. Multiple complete-model supplier listings identify 12 VDC, 2.40 A and a four-wire connection.
Is BFB1012SHA01 an axial fan or a centrifugal blower?
It is a graphics card-style centrifugal blower with a radial impeller. Some supplier catalogs classify it generically as a cooling fan or axial fan, but its physical GPU blower design differs from a conventional square axial fan.
What is the rated voltage?
Complete-model suppliers consistently specify 12 VDC. A manufacturer approval document establishing the full allowable operating voltage range was not independently located.
What is the listed input current?
Multiple suppliers identify 2.40 A for BFB1012SHA01. Confirm the rating printed on the supplied fan and ensure the graphics card fan power circuit is appropriate.
What is the input power?
Multiplying the supplier-listed 12 VDC by 2.40 A gives 28.80 W. This is a calculated electrical reference, not an independently verified typical or maximum operating-power value from Delta.
What are the dimensions of BFB1012SHA01?
Several suppliers list approximately 75 x 75 x 27 mm, while another retail listing gives 76 x 76 x 25 mm. Verify actual housing dimensions, impeller diameter and clearance against the removed fan.
How many wires and connector pins does the fan have?
Multiple exact-model listings specify four wires and a four-pin connector. Pin positions, wire colors and connector keying must match the graphics card's cooling assembly.
Does BFB1012SHA01 support PWM speed control?
Some GPU replacement sellers advertise a four-pin PWM version. However, the specific PWM signal requirements and wire assignments were not independently confirmed from an exact-model Delta engineering datasheet.
What is the rotational speed?
One retail listing states 6000 RPM, but a matching Delta performance specification confirming that figure was not established. Confirm the exact fan variant if rotational speed is required for engineering evaluation.
What are the airflow, static pressure and noise specifications?
Reliable manufacturer-confirmed CFM, maximum static pressure and acoustical noise ratings for the complete BFB1012SHA01 model were not established. These values should not be inferred from other Delta BFB-series products.
Which graphics cards are listed as compatible?
Replacement suppliers mention selected AMD Radeon RX Vega 56, RX Vega 64, R9 390X and Radeon HD-series reference cooler assemblies. Compatibility is not universal across every graphics card bearing these GPU names; different board manufacturers and revisions can use different fan mounts.
What should be checked before ordering Delta BFB1012SHA01?
Confirm the complete BFB1012SHA01 fan marking, 12 VDC supply, 2.40 A listed current, actual housing dimensions, approximately 75 mm impeller diameter, mounting-hole geometry, four-pin connector, cable length, wire order, airflow outlet direction and exact graphics card cooler compatibility. Supplier mounting-hole measurements conflict, so direct comparison with the installed fan is especially important.
