40 mm 4-wire dual ball-bearing case fan

This TSUJ Kepler-C72J-OYS-0396 accessory is a 4015 frame cooling fan that runs on 12 V at 0.24 A. The four-wire PWM connector allows automatic speed control from the motherboard. Dual ball bearings reduce friction and extend operating life in continuous use.

Replaces worn or noisy 40 mm case fans

The unit fits any chassis or heatsink cut-out designed for a 4015 frame with standard four-wire PWM control. It is not suited for builds that require larger frame sizes, higher airflow ratings, or voltage levels other than 12 V.

Questions about this item

What mounting-hole spacing does the 4015 fan frame use?

The 4015 designation indicates a 40 mm square frame; check the supplied mounting hardware for the exact hole centres.

How is the 4-wire PWM connector attached, and what mistake should I avoid?

Align the keyed 4-pin plug with the motherboard header and press straight down; forcing it sideways bends the pins.
