Compact 80mm case fan for tight builds

This 80mm case fan fits small-form-factor chassis and low-profile CPU coolers where larger units cannot mount. The rifle-bearing design spins between 2000 and 2499 RPM while producing 20 to 25 dBA of noise. A standard three-pin connector provides direct voltage control on most motherboards.

Builders who need quiet airflow in confined spaces

The 25 to 30 CFM output suits compact workstations and HTPC cases with restricted ventilation paths. Buyers who require higher static pressure for dense radiators or significantly greater airflow for full-size towers should look elsewhere. The non-LED black frame keeps the appearance neutral in windowed builds.

Three-pin voltage control limits automatic speed

The fan uses a three-pin power connector so speed is regulated by varying voltage rather than a PWM signal. Motherboards that only implement duty-cycle control on four-pin headers cannot modulate this fan automatically. Check your board’s header specification before purchasing.

Questions about this item

What speed does the 3-pin connector limit the fan to?

The 3-pin connector supplies 12 V and allows the fan to run at its rated 2000-2499 RPM range; speed control depends on the motherboard varying voltage.

Will the 80 mm frame with 25 mm depth fit my case or cooler mount?

The fan measures 80 mm by 80 mm by 25 mm, matching the standard 80 mm mounting pattern used on cases and CPU coolers.

How do I connect the three pins so the motherboard reads the speed correctly?

Align the keyed 3-pin plug with the motherboard header tab, press it fully home, then enable fan monitoring in BIOS so the tachometer signal is read.
