92mm case fan with thermal sensor

This 92mm case fan operates between 3500 and 3999 RPM and delivers 80 CFM of airflow. It uses a 2 Ball bearing and a 3 Pin power connector. A built-in thermal sensor allows automatic speed adjustment based on temperature. The frame measures 92 x 92 x 32 mm and has a black finish with no LED lighting.

Suits builds needing a 92mm mount

The 92mm size fits cases designed for that specific mounting pattern. The 15 to 20 dBA noise range works for quiet systems. Builders requiring higher static pressure for dense radiators or larger fan mounts should consider other options. The 3 Pin connector provides voltage control but not PWM signalling.

3500-3999 RPM range determines cooling capacity

This speed band sets the maximum airflow of 80 CFM and the associated noise level. If your thermal design needs more airflow than this range provides, the fan will not meet the requirement. Verify that your fan header supports 3 Pin voltage control before installing.

Questions about this item

Does the 3-pin connector on the M35172-57 require a motherboard header or a fan controller to power the 92mm fan?

The 3-pin connector plugs directly into a standard motherboard 3-pin fan header or a compatible fan controller to supply power and allow speed monitoring for the 92mm case fan.

Will the 3500-3999 RPM range and 80 CFM airflow of this 92mm fan overwhelm older case ventilation paths designed for slower fans?

The 80 CFM airflow at 3500-3999 RPM moves more air than many legacy 92mm fans; ensure your case vents and dust filters are clean so the higher static pressure does not create turbulence or noise.

How can I confirm the thermal sensor is adjusting the 92mm fan speed between 3500 and 3999 RPM after installation?

Monitor the fan RPM in BIOS or software; the reading should rise toward 3999 RPM as component temperatures climb and fall toward 3500 RPM when the system cools.
