Suited to server and inverter chassis needing

Builders who require a different voltage, a smaller frame or a non-PWM connector should look elsewhere. The 38 mm thickness may not fit slim enclosures. No other mounting hardware or adapters are included.

Questions about this item

Does my system need a 12 V DC header to run the RZ1238H12B fan?

Yes — the fan is rated for 12 V DC at 2.70 A, so the motherboard or controller must supply a 12 V header capable of at least that current.

Will the 120 mm × 38 mm frame fit the same mounting holes as my existing 12038 fans?

The 120 × 120 × 38 mm dimensions match the standard 12038 footprint, so it aligns with the same four-hole pattern used by other 12038 units.
