Sudokoo MACH120 120 mm 30 mm Case Fan

The Sudokoo MACH120 is a single 120 mm case fan with a 30 mm thick frame designed for high static pressure cooling. It uses a 3-phase 10-pole 12-slot FOC motor with a hybrid hydraulic bearing and liquid crystal polymer blades reinforced with 40 % glass fibre. Speed is controlled via a 4-pin PWM connector across a 500-3000 RPM range.

Builders targeting dense radiators

The thick 30 mm frame and 7.31 mmAq static pressure suit builders who need strong airflow through dense fin stacks. The hybrid hydraulic bearing and sub-39.9 dB(A) noise level also fit quiet-focused systems. Users who require RGB lighting or a slimmer profile for tight clearances should consider other models.

30 mm frame depth for radiator clearance

The 30 mm thickness directly determines whether the fan clears a radiator or heatsink in your build. Verify that your case or mounting hardware accepts a 30 mm fan before purchasing.

Questions about this item

How do I install the 120mm 30mm fan in my case and what step do people get wrong?

Mount the fan using the four corner holes with the supplied screws, then connect the 4-pin PWM header to the motherboard. The common mistake is forgetting to enable PWM control in BIOS so the fan stays at a fixed speed instead of following the 500-3000 RPM curve.

What maintenance or replacement will the hybrid hydraulic bearing need later?

The dual-circuit hybrid hydraulic bearing is sealed for life and requires no lubrication. If noise rises above the rated 39.9 dB(A) after several years, replace the entire fan unit — bearings are not user-serviceable.

At what point does the 7.31 mmAq static pressure limit show up first under sustained load?

The 7.31 mmAq static-pressure ceiling is reached when the fan hits 3000 RPM against a dense radiator or filter. Beyond that point airflow drops sharply while noise approaches the 39.9 dB(A) maximum.
