Case fan for airflow builds

The Fans efwf-45f05m-b is a case fan designed to move air through a computer chassis. It suits builders assembling a new system or replacing an existing cooler. The part arrived on the market in 2021 and is supplied in new condition.

45 millimetre frame thickness

The single specification that determines fit is the 45 millimetre frame thickness. This dimension decides whether the fan clears side panels, cable routing or radiator mounts in a given case. Check the available depth before ordering.

Fits standard 45 mm slots

This fan suits builds that accept a 45 millimetre thick unit in the designated mounting points. Builders needing a slimmer profile for tight clearances or a different mounting pattern should look at other options.

Questions about this item

The 45 mm square frame determines the mounting footprint; it will only fit locations cut for that exact dimension.

What interface does the fan use and what does it limit in practice?

The fan connects via a standard power header; the connector type fixes the available speed control method.

What physical mounting holes or brackets does this fan need to fit?

The 45 mm square frame uses corner mounting holes spaced for that size; verify your case or heatsink has matching holes.
