Start with the space available for the blower and the voltage supplied by your equipment. Open a model page to check its mounting dimensions, outlet position and performance curve.
Use the table to shortlist models by size and rated voltage. Each row shows the airflow, static pressure and noise ratings for the example configuration. Open the model page to check other speed options and the performance curve.

| DC9733 | 97 x 94 x 33 mm | 12V, 24V | 12V / 6,500 RPM | 52.27 CFM | 113.74 mmH₂O | 63.60 dBA |
Airflow and static pressure ratings represent separate points on the performance curve. Use the curve to estimate airflow at your equipment’s expected pressure drop.
Start with the airflow path inside the equipment. Identify where air enters, which components it needs to cool and where it exits. Then check the mounting dimensions, electrical requirements and performance at the expected system resistance.
Measure the available width, height and depth. Check where the outlet needs to meet the duct or enclosure opening, and allow clearance around the inlet. Use the model drawing to confirm mounting holes and housing dimensions.
Choose a version that matches your equipment’s DC supply. Check rated current, connector pinout and any speed control or feedback requirements. If your design needs PWM, FG or RD, confirm the available functions and wiring for the exact model.
Ducts, grilles, filters and dense heat sinks can restrict airflow. Compare the blower’s P–Q curve with the system resistance curve to estimate the operating point. If system resistance is unknown, evaluate cooling with a sample installed in the equipment.
A side outlet can help route air through an enclosure where space or vent position limits the cooling layout. These three examples show what to check for each airflow path.
01
02A narrow duct can direct air toward a component away from the blower. Check the resistance added by bends, changes in duct width and the outlet opening. For designs that can accommodate a 75 x 75 x 30 mm blower, review the DC7530 voltage and speed options.
03Position the outlet so air passes across the heat sink fins. If closely spaced fins or nearby components restrict airflow, use the DC9733 performance curve to check the available airflow at the expected pressure drop.

Find answers about blower sizes, supply voltage, installed airflow, speed control, replacements and OEM purchasing.
Consider a blower when the equipment needs to direct air through a side outlet, into a narrow duct or across a specific heat sink. An axial fan can suit an enclosure with a clear path straight through the fan frame. If both layouts fit, compare the airflow each option delivers at the expected system resistance.
Voltage options vary by model. The DC2006 measures 20 x 20 x 6 mm and comes in 5V and 12V versions. The B8020 measures 80 x 80 x 19 mm and comes in 12V and 24V versions. The DC7530 measures 75 x 75 x 30 mm and comes in 12V, 24V and 48V versions. Use the model drawing to confirm mounting dimensions and outlet position.
Match the blower to the equipment’s supply voltage, then compare rated current, speed and the performance curve. The 12V and 24V versions of the B8020, for example, list the same airflow and static pressure at corresponding speed ratings. Check the specifications for the exact version you plan to order.
The intersection of the blower’s P–Q curve and the system resistance curve estimates the installed airflow. Ducts, filters, grilles and dense heat sinks can increase resistance and reduce airflow. If system resistance is unknown, check cooling performance with a sample installed in the assembled equipment.
Check the mounting holes, housing clearance and outlet position, then verify the voltage, connector pinout and airflow requirements. The DC5015 measures 50 x 50 x 15 mm, while the DC5015F measures 52 x 51 x 15 mm. Compare their drawings and wiring before choosing a replacement.
Some configurations offer PWM speed control, FG speed feedback or RD rotation detection. Confirm the available functions and pinout for the exact part number. If the blower runs at a low setting after startup but will not start from rest at that setting, check the model’s startup requirements and verify the behavior with your controller.
Compare noise ratings for configurations that meet your airflow and pressure requirements. Then check the sound in the assembled equipment, where mounting, inlet clearance and duct geometry can affect what users hear. If buzzing occurs only at certain speeds, check both the speed control settings and the mounting.
Send your housing, voltage, cable, connector or control requirements for an OEM or ODM review. You can also request a dimension drawing, performance curve and any test or certification documents your project requires. Confirm which options and documents are available for the exact configuration.
Send the target model or existing part number, available mounting space, supply voltage, connector details, required airflow or static pressure, and estimated quantity. If you do not have airflow data, include a drawing or photo showing the equipment and its airflow path. These details help YCCFAN review model fit, sample availability, MOQ and lead time.
