Compact 12V Case Fan

The TSUJ Kepler-C72J-OYS-0326 is a 4020 form-factor case fan designed for 12V systems. It draws 0.15A and connects via a three-wire, three-pin header. The unit suits builders needing a small airflow device for tight chassis spaces.

Thermals Noise and Power

Operating at 12V and 0.15A, the fan consumes minimal power during normal operation. The three-pin connection allows basic speed reporting to the motherboard. Acoustic output remains low thanks to the compact 4020 frame and modest current draw.

Sustained Load Behaviour

Under continuous duty the fan maintains steady rotation at the rated 12V 0.15A specification. The three-wire design supports ongoing RPM monitoring without PWM control. Long-term reliability suits always-on or server-type workloads within the stated electrical limits.

Questions about this item

How do I install the TSUJ Kepler-C72J-OYS-0326 fan and which wire is the tachometer?

Mount the 4020 frame with four screws, then plug the 3-pin connector so the yellow wire aligns with the motherboard's tachometer pin; reversing the yellow and black wires is the common mistake that stops speed reporting.

What maintenance will this 12V 0.15A case fan need over time?

Expect to clean dust from the 4 cm blades every few months; the sleeve bearing cannot be relubricated, so plan to replace the unit once noise or vibration appears.

What is the first limit reached when this 3-wire fan runs continuously at 12 V?

The 0.15 A current draw is fixed, so the sleeve bearing's heat tolerance becomes the limiting factor before any electrical threshold is hit.
