Fans

Fans DP201A 2123HBT 220V 120mm case fan

SKU CH-CCMF-9QT38 MPN DP201A

120 mm AC case fan runs on 220–240 V, delivers 160–188 m³/h airflow at 2750–3050 rpm with 42–48 dBA noise

  • High airflow of 160 to 188 m³/h cools dense component layouts
  • Double ball bearing extends operating life in continuous use
  • AC 220 V direct connection removes need for extra power supply
  • Wide -20 °C to 85 °C range suits industrial environments
  • Compact 120 mm square frame fits standard case mounts

Industrial-grade AC case fan

The Fans DP201A is a 120 mm square AC fan built around a genuine SUNON 2123HBT motor with an aluminium frame and dual ball bearings. It runs directly from 220 V to 240 V mains at 50 Hz or 60 Hz, drawing 19 W to 20 W. The unit is rated for continuous operation in environments from -20 °C to 85 °C.

Sustained-load airflow and noise

At 50 Hz the fan spins at 2 750 r/min and moves 160 m³/h with a static pressure of .33 Inch-H₂O while producing 42 dBA. At 60 Hz the speed rises to 3 050 r/min, airflow reaches 188 m³/h, static pressure climbs to .38 Inch-H₂O and noise increases to 48 dBA. These figures are steady-state ratings, not peak bursts.

Mains-powered interface limits

Because the fan connects straight to 220 V–240 V AC, it cannot be speed-controlled by a motherboard PWM header or a standard 12 V DC fan controller. Wiring requires mains-rated cabling and appropriate safety isolation. The 38 mm thickness and 120 mm mounting pattern suit industrial chassis and server enclosures that accept AC-powered axial fans.

Questions about this item

How loud does the DP201A 2123HBT run at full speed in a closed case?

The fan produces 42 dBA at 50 Hz and 48 dBA at 60 Hz, measured at 2750 and 3050 r/min respectively.

What mains connection does the 220 V AC frame need to operate?

It plugs directly into a 220–240 V, 50/60 Hz socket; no external DC supply or motherboard header is required.

Will the 120 mm aluminium frame fit the same mounting holes as my older 120 mm fans?

Yes — the 120×120×38 mm dimensions match the standard 120 mm hole pattern used for decades.
