40 mm DC 5 V Side Blower

This 40 mm centrifugal turbine blower runs on 5 V DC and draws 0.30 A. The side-blowing layout pushes air across tight component stacks rather than straight down. A 10 mm frame depth lets it fit in slim enclosures where standard axial fans cannot. It is sold as a single unit for targeted spot cooling.

Suits compact PCs and industrial chassis

Builders who need a low-profile blower for narrow ducts or small-form-factor cases will find the dimensions and voltage a direct match. Buyers who want higher airflow volume or PWM speed control should look elsewhere, as this model provides fixed-speed operation only. Shoppers requiring larger frame sizes or different voltage rails will need a different fan.

Highlights

  • Compact 40 mm frame fits tight builds
  • 10 mm thickness suits low-profile cases
  • 5 V 0.30 A draw keeps power use low

Questions about this item

How do I install the BSB0405LA 40mm side blower fan and which step is often missed?

Mount the 40*40*10mm frame with four screws, connect the two-wire lead to a 5 V header, and ensure the side exhaust port faces the component you want to cool — the directional outlet is the step most builders overlook.

What maintenance will the BSB0405LA centrifugal blower need over time?

Periodically remove dust from the turbine blades and intake vents with low-pressure air; the sealed sleeve bearing is not user-serviceable, so replace the unit if noise or airflow drops noticeably.
