50-pack 40 mm case fans

This pack contains fifty 40x40x20 mm case fans that run on 12 V power. The double ball bearing design is built for continuous operation in tight enclosures. They suit system integrators who need a consistent supply of compact cooling units.

Double ball bearing reliability

The bearing type reduces friction and extends service life compared with sleeve alternatives. This makes the fans appropriate for equipment that must run for long periods without maintenance. Buyers who require PWM speed control or a different voltage should look elsewhere.

Questions about this item

How long do the double ball bearings last before replacement?

Double ball bearings typically outlast sleeve bearings by several years under continuous 12 V operation, so replacement is rarely needed during normal system life.

What limits continuous running at full speed?

The 40 mm frame and 20 mm thickness restrict airflow, so motor heat builds up first during sustained 12 V load.
