Industrial AC Case Fan

The SXDOOL IKURAFAN UHS4556M is an AC-powered case fan built for 220 V mains supply. Its all-metal frame measures 120 mm by 120 mm by 38 mm and is rated for high-temperature resistance. The unit targets industrial enclosures and server cabinets that require robust airflow without a separate DC power source. It suits builders who can wire directly to AC mains.

Suited For And Limitations

This fan suits installers needing a 12038 form factor that runs from 220 V AC without a power supply unit. It is not for builders who need PWM speed control, standard 12 V DC headers, or low-voltage safety wiring. Buyers wanting quiet residential operation or software fan curves should look elsewhere. The fixed-speed design also limits tuning for noise-sensitive workstations.

Deciding Specification

The defining specification is the AC 220 V 18/20 W power rating combined with the 120 mm by 120 mm by 38 mm all-metal housing. This voltage and frame size determine whether the fan fits the cutout and wiring of the target enclosure. Verify that the chassis accepts mains-voltage fans and the 12038 mounting pattern before purchase.

Questions about this item

Does the AC 220 V connection limit the fan to fixed-speed operation?

Yes, the fan runs directly from 220 V mains at 18 W or 20 W with no PWM or voltage control built in.

Will the 120 mm by 120 mm by 38 mm all-metal frame fit a standard 120 mm case mount?

The 120 mm square footprint matches standard mounts, but the 38 mm thickness and metal construction need clearance for depth and weight.

How is the IKURAFAN UHS4556M wired into a PC, and what mistake do builders make?

It must be wired to a 220 V AC source — typically a separate IEC lead — not to a motherboard header; connecting it to 12 V DC will damage the motor.
