SKU CH-S2Y1-NSW50 MPN RAH1238S2

A 120 × 120 × 38 mm cabinet fan running on 100–125 V at 0.30 A for chassis cooling

  • TypeCase Fan
  • 120×120×38 mm footprint fits standard 120 mm mounts
  • 100–125 V AC input powers directly from mains supply
  • 30 A draw keeps energy use low
  • 38 mm thickness allows high static pressure
  • Tested before dispatch to confirm reliable operation

High-voltage AC case fan

The CAFELE RAH1238S2 is a 120×120×38mm frame fan designed for 100-125V AC mains input at 0.30A. It serves as a direct replacement for cabinet or server enclosures that require high-voltage cooling without a separate power supply.

Installers replacing a 12038 AC unit

This unit suits technicians swapping a failed high-voltage fan in industrial cabinets, telecom racks or legacy server chassis where the wiring delivers 100-125V AC. Builders assembling new PCs with standard 12V DC headers cannot use this fan and should select a low-voltage PWM model instead.

100-125V AC operating voltage

The defining specification is the 100-125V AC rating at 0.30A; the fan connects directly to mains-voltage wiring rather than a motherboard header. Verify that the target enclosure supplies this exact voltage and that the 38mm thickness clears the mounting location before ordering.

Questions about this item

What voltage supply do I need to run the RAH1238S2 120×120×38 mm fan?

The fan is rated for 100-125 V AC, so a standard mains outlet in that range is required; no separate low-voltage adapter is used.

Will the 12038 frame size line up with the mounting holes on my existing 120 mm fan bracket?

Yes — the 120×120 mm footprint matches common 120 mm brackets, but verify the 38 mm thickness and hole pattern against your old unit before fitting.

How can I confirm the fan is spinning correctly after installation?

Power the system and listen for steady airflow; the 0.30 A current draw indicates normal operation, and the blades should turn smoothly without vibration.
