Questions about this item

Does the 12 Vdc connection use a standard 3-pin or 4-pin header?

The assembly is built for the Dell OptiPlex 380 and 390 chassis and uses the proprietary connector keyed for those models.

What clearance does the 92 mm frame need inside the case?

It mounts directly to the OptiPlex 380 or 390 fan bracket using the original screw holes, so no extra clearance is required.

How is the fan installed, and which step is often missed?

Remove the old X755M unit, align the Sunon EE92251S3-D020-C99 assembly with the bracket posts, secure the screws, then press the connector firmly until it clicks.
