40 mm 12 V DC case fan

The CHA4012DB-M is a compact 40×40×20 mm case fan that runs on 12 V DC and draws 0.18 A. Its two-wire design provides basic cooling airflow for tight spaces inside a chassis or small enclosure. The small frame fits where larger fans cannot, making it a practical choice for targeted component cooling or replacement in legacy systems.

Fit for tight 40 mm mounts only

This fan suits builders who need a 40 mm frame with a two-wire 12 V connection. It does not meet the needs of users who require PWM speed control, higher static pressure, larger frame sizes or different voltage ratings.

Questions about this item

How do I install the CHA4012DB-M fan and which step is often missed?

Mount the 40×40×20 mm frame with four screws, then connect the two-wire lead to a 12 V header; the step most people miss is checking airflow direction so the fan blows the right way.

What maintenance will the CHA4012DB-M need later?

Clean dust from the blades and vents every few months with compressed air; the sleeve bearing cannot be relubricated, so plan to replace the fan when noise or vibration increases.
