  • Compact 40 mm frame fits tight chassis spaces
  • Double-ball bearing extends operational lifespan
  • 15 600 RPM delivers 20.6 CFM focused airflow
  • 385 inH₂O static pressure pushes air through dense obstacles
  • 3-pin 12 V connector enables simple motherboard control

Compact 40 mm case fan for tight builds

The CAFELE THA0412AD is a 40 mm square fan designed for small-form-factor chassis, server blades and industrial enclosures where space is at a premium. It runs on 12 VDC and draws 0.60 A, delivering 5.16 W of cooling power through a double-ball bearing assembly.

Upgrade from sleeve-bearing or slower 40 mm fans

Replace an ageing sleeve-bearing unit that has become noisy or a lower-RPM fan that no longer moves enough air. The 15600 RPM motor pushes 20.6 CFM at 1.385 inches of water column, making the jump worthwhile when components run hotter than before or when the original fan has failed.

Check 3-pin header, voltage and physical clearance

Verify that your board or fan controller provides a 12 V three-pin header; the fan will not start on 5 V or a two-pin connector. Measure the mounting holes — 40 mm centre-to-centre — and confirm 20 mm depth fits behind the panel or heatsink. Noise reaches 52 dB(A) at full speed, so ensure the environment tolerates that level.

Questions about this item

Will the 40×40×20 mm frame fit my chassis fan slot?

The fan measures 40 mm square by 20 mm thick, so it fits any standard 40 mm mounting hole pattern.

How do I connect the 3-pin connector without running it at full speed constantly?

Plug the 3-pin header into a motherboard fan header or fan controller; the board regulates voltage to vary the 15600 RPM speed.

When should I plan to replace the double ball bearing assembly?

Double ball bearings typically last several years at 52 dB(A); replace the fan if noise rises or airflow drops below 20.6 CFM.
