90mm PWM fan for compact CPU cooling

This 90mm square cooler from DELTA fits tight CPU sockets where taller towers cannot. The AFB0912HH F00 model runs on 12V at 0.4A and targets builders assembling small-form-factor or replacement systems. Its black frame and absent LEDs keep the look neutral inside any chassis.

Four-pin connector enables direct motherboard

The 4-wire PWM header plugs straight onto a standard CPU fan header so speed adjusts automatically with temperature. Ball bearings reduce startup friction but can develop audible whine after extended use. No mounting hardware is included, so verify your retention bracket matches the 90x20mm footprint before purchase.

90x20mm frame limits airflow versus larger coolers

The 20mm thickness and 90mm blade diameter restrict static pressure, making this fan suited to low-TDP processors rather than high-heat loads. PWM control cannot overcome the physical ceiling of the smaller impeller. Systems demanding sustained heavy loads will need a larger heatsink or liquid loop.

Questions about this item

How do I confirm the AFB0912HH F00 is running correctly after installation?

The 4-pin PWM connector lets the motherboard report real-time RPM in BIOS or monitoring software; a steady reading that changes with load shows the ball-bearing fan is spinning as intended.

What comes in the box and what must I source separately?

The package contains the 90x20mm DELTA fan with its 4-wire lead; mounting screws, a heatsink base or PWM fan hub are not included and must be purchased if your build needs them.

Which version of this cooler should I choose for a 12V 0.4A header?

The AFB0912HH F00 is the only model listed and it is rated 12V 0.4A, so it matches a standard 4-pin CPU fan header without needing a different variant.
