Compact 3 cm SEPA 3012 fan for notebook hard-drive

The SXDOOL SEPA 3012 measures 3 cm square and runs on a 5 V, 0.2 A supply. It is designed as a case-fan accessory that fits tight notebook hard-drive bays where larger coolers cannot be installed. The double-ball bearing motor targets users who need reliable airflow in a very small form factor.

Double-ball bearing eases installation in tight bays

The double-ball bearing design reduces friction so the fan spins freely even when mounted at odd angles inside cramped chassis. Clearance is the main difficulty — the 3 cm frame leaves almost no margin for cable routing or screw heads, so verify the bay depth before fitting. No PWM or speed-control header is present, so the fan runs at full speed whenever power is applied.

Questions about this item

How can I confirm the SEPA 3012 fan is running correctly after connecting it to a 5 V header?

The double ball bearing motor should spin smoothly and quietly at the rated 0.2 A draw; check for steady airflow from the 3 cm frame and listen for any rattling that would indicate a bearing issue.

What comes with the SEPA 3012 cooler and do I need a separate power cable?

Only the fan unit itself is included; it has a built-in lead for a standard 5 V connection, so no extra cable is required unless your header uses a different connector type.
