  • Compact 90 x 25 mm frame with 3-pin 6.5-inch connector

Sunon KD1209PTS2 90 mm 12 V fan

This 90 mm by 25 mm DC fan runs at 12 volts and delivers 44.0 CFM of airflow at 2400 RPM. It produces 32 dBA of noise and 0.14 H2O of static pressure while drawing 1.7 watts. The unit suits builders adding spot cooling to tight chassis spaces or replacing a matching 90 mm mount. It is not for systems that require larger frame sizes or higher static-pressure ratings.

Three-pin 6.5-inch connector installs in seconds

The 3-pin plug fits standard motherboard or controller headers without adapters. Four corner screw holes align with common 90 mm mounting patterns for a secure fit. The only common issue is cable reach in larger cases where the 6.5-inch lead may fall short of the header. Builders needing PWM speed control should note this model lacks a fourth pin.

Questions about this item

How do I verify the fan is spinning at 2400 RPM after installation?

Check the RPM reading in BIOS or monitoring software; it should report approximately 2400 RPM and the 3-pin connector allows the motherboard to display the speed signal.

What comes in the box and do I need a 4-pin adapter or mounting screws?

The box contains the 90x25mm fan with a 3-pin 6.5-inch connector; mounting screws and any 4-pin adapter are not included and must be sourced separately.
