92 mm 12 V axial case fan
The SUNON KD1209PTS3 is a 92 mm square axial fan built for case ventilation in PCs and embedded systems. It runs on 12 V and draws 0.14 A for a rated power of 1.7 W. The ball-bearing motor is rated for 50000 hours of continuous operation.
Practical limits of 12 V axial cooling
At 2100 RPM the fan delivers 30 to 35 CFM of airflow while producing 28 dB-A of noise. The 25 mm frame depth fits standard 92 mm mounting holes, but the fixed speed and single-voltage design mean airflow cannot be adjusted without external control. It suits steady-state cooling where variable flow is not required.
35 CFM at 28 dB decides fit
The 35 CFM peak airflow at 28 dB is the specification that determines whether this fan meets a build's thermal and acoustic targets. Buyers needing higher static pressure, PWM speed control or lower noise at the same airflow will need a different solution.

Questions about this item
Should I pick the 30 CFM or 35 CFM end of the airflow range?
The fan is rated 30-35 CFM; 35 CFM is the maximum at 2100 RPM, 30 CFM is the minimum — choose based on how much cooling headroom you want.
What does 35 CFM actually deliver inside a case?
At 35 CFM the 92 mm fan moves enough air for modest component cooling or heat-exchanger airflow in a tight 25 mm slot.
The fan uses a 12 V 0.14 A ball-bearing motor — what does that limit?
It draws 1.7 W at 12 V, so any 12 V header or controller rated above 0.14 A can run it at the full 2100 RPM.
