Compact 40 mm dual-ball case fan
This 40 x 40 x 20 mm case fan runs on 12 V and draws 0.15 A. The dual-ball bearing design targets builders who need reliable airflow in tight chassis spaces or on small-form-factor boards. It suits systems where a low-profile cooler is the only option.
Limited by 40 mm frame and fixed voltage
The 40 mm square frame restricts total air volume compared with larger fans. Operation is fixed at 12 V with no PWM or speed-control header mentioned, so airflow cannot be adjusted by the motherboard. Buyers who need variable speed or higher static pressure should look elsewhere.

Questions about this item
How do I pick between the 4012 and 4020 model numbers shown for this fan?
The 4012 code is the series identifier and 4020 shows the 40 mm by 20 mm frame size, so both refer to the same 40x40x20 mm unit.
What does the 0.15 A current draw mean when the fan is running in my system?
At 12 V the fan pulls 0.15 A, giving a low power load that fits standard motherboard headers and small-case builds.
