Replacement CPU Fan for HP Omni Series

This four-pin laptop CPU fan fits HP Omni 220, 320, 420, 520 and 620 models using part number 1323-00DU0H2. It serves as a direct swap for a worn or noisy original cooler in those all-in-one systems. Each unit is tested before dispatch to confirm it spins correctly. Buyers with different HP chassis or proprietary connector layouts cannot use this cooler.

Sustained Cooling Behaviour

The fan draws power through a standard four-pin header, allowing the motherboard to regulate speed based on thermal load. Under continuous workloads the PWM control keeps airflow steady without the voltage drops seen on three-wire designs. Bearing type varies between Forcecon, ADDA, Sunon or Kipo depending on stock, so acoustic profile may differ between units. No liquid-cooling integration or external controller support is provided.

Upgrade Context and Fit Check

This part replaces the factory KUC1012D cooler when bearings fail or airflow degrades over time. The jump is worth it when the original fan rattles, overheats the CPU or triggers thermal throttling during long sessions. Systems outside the listed Omni range, or those using a different pin-out, require a different cooler. Verify the part number on your existing fan before ordering to avoid mismatch.

Questions about this item

How loud is the 4-pin KUC1012D fan when the Omni 620 runs all day?

The 4-pin connector allows PWM speed control so the fan only spins as fast as the HP Omni 220, 320, 420, 520 or 620 thermal curve demands, keeping noise proportional to load.

What must my HP laptop already have for this KUC1012D replacement to fit?

Your HP Omni 220, 320, 420, 520 or 620 must use the original 1323-00DU0H2 4-pin CPU fan; the replacement matches that exact mounting and connector layout.

Will this Forcecon, ADDA, Sunon or Kipo built fan align with the heatsink screws on my older Omni 320?

Yes — the fan is tested against the 1323-00DU0H2 specification used across Omni 220, 320, 420, 520 and 620 models, so the screw holes and 4-pin header line up.
