92 mm 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.

Square

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.

High-Temperature Equipment-Cooling Fans

While standard equipment-cooling fan motors degrade when used in high-temperature areas, these fans run continuously without issue in temperatures up to 190° F. They are made entirely of metal and are lubricated with high-temperature bearing grease. This means they are often used to cool electronics near higher temperature areas, such as near commercial ovens. These fans have ball bearings that reduce friction as they run, extending their life. Their bearings also decrease noise for quiet operation.
