Fans AFC0912DESize 90x90x38mm 12V 4-pin case fan

SKU CH-XPN7-X7V4H MPN AFC0912DESize

A 90 mm double ball-bearing case fan delivers 39.17–180.97 CFM at 5,500 RPM with a 4-pin PWM connector

  • Double ball bearings extend service life to 80,000 hours
  • 4-pin PWM connector enables precise 5500 RPM speed control
  • High airflow range of 39.17 to 180.97 CFM delivers strong cooling
  • 44 dBA noise reference keeps acoustic levels moderate
  • Compact 90x90x38mm frame fits standard 92mm mounting

Purpose and audience

The Delta AFC0912DE is a 90 mm square case fan built for systems that need strong airflow in a compact frame. It suits builders who want high static pressure for radiators or dense heatsinks and who prefer a 4-pin PWM connection for precise speed control.

Build integration

The fan fits standard 90 mm or 92 mm mounting holes and draws 0.5 A at 12 V, peaking at 2.5 A during spin-up. Its 4-wire connector plugs directly into a motherboard PWM header, freeing a 3-pin header for other devices and allowing the board to modulate RPM without extra controllers.

Sustained-load behaviour

Double ball bearings and an 80,000-hour rated life keep the fan stable during continuous operation. Speed holds at 5500 RPM ± 10 % while moving between 39.17 and 180.97 CFM at a noise level of 44 DBA, so airflow remains consistent during long rendering or compute sessions.

Questions about this item

How long is the rated working life before the bearings reach their limit?

The double ball bearing design is rated for 80000 hours of continuous operation.

What noise level and power draw should I expect when the fan runs at full speed all day?

At 5500 RPM the fan produces 44 dBA while drawing 2.50 A at 12 V.

Does my motherboard need a specific header to use the 4-pin connector?

A standard 4-pin PWM header supplies the 12 V and speed control the fan requires.
