- 12 V DC power fits standard PC headers
- 20 °C to 75 °C range handles harsh environments
92 mm IP54 axial fan
The ebm-papst 3312U is a 92 mm square DC axial fan rated at 12 volts and 2.5 watts. It delivers 47 CFM of airflow at a noise level of 37 decibels. The plastic housing carries an IP54 rating for dust and splash protection. This fan suits builders who need a compact, water-resistant cooling device for tight chassis spaces.
12 V DC lead connection
The unit operates on a 12 volt DC supply drawing 0.2 amps and terminates in bare leads rather than a standard motherboard header. No PWM or speed-control signal is provided, so speed is fixed at the rated voltage. Builders who need variable speed control or a 3-pin or 4-pin connector must add external circuitry or choose a different model.
47 CFM in -20 to 75 °C range
At 47 CFM the fan can move enough air for small-form-factor cases, industrial enclosures or heat-exchanger ducts within the stated temperature limits. The IP54 seal helps in damp or dusty environments, but the single fixed speed may not satisfy high-static-pressure radiators or silence-focused builds that demand lower noise at idle.

Spørsmål om denne varen
Should I pick the 92 mm fan with 2.5 W power draw or a higher-wattage model?
The 92 mm frame and 2.5 W rating give 47 CFM airflow at 37 dB; choose it when space and power budget are tight, otherwise a larger or higher-wattage fan moves more air.
What does 47 CFM actually deliver inside a chassis?
47 CFM pushes enough air through a 92 mm vent to cool a modest heat load such as a low-TDP CPU or a small radiator without creating high static pressure.
How does the IP54 rating affect where I can mount this fan?
IP54 means the motor and electronics resist dust ingress and water splashes, so the fan can sit near intake filters or in damp industrial enclosures without failing.
