4.69" Fans | McMaster-Carr

Running on 48V DC power or lower, these compact fans fit inside electronics and other small, heat-sensitive equipment to keep things cool. They're also known as muffin fans. Some meet American and Canadian safety standards.

Quick-Disconnect Terminal Connection—Fans with quick-disconnect (QD) terminals are compatible with quick-disconnect power cords.

Ball Bearing—Fans with ball bearings generate less heat as they run, so they have a longer life than fans with plain bearings.

Plain Bearing—Fans with plain bearings are good for less demanding applications, such as cooling prototypes or parts that aren’t used often.
