Compact 70 mm case fan for tight builds
The Rexus DF127015PH is a 70 mm case fan designed for small-form-factor chassis where larger fans cannot fit. It targets builders who need directed airflow in cramped layouts such as mini-ITX cases or rackmount enclosures. The three-pin connector provides simple voltage control on most motherboards.
4300 RPM speed delivers 38.9 CFM airflow
The single specification that determines fit is the 4300 RPM rotational speed, which produces 38.9 CFM of air movement through the 70 mm frame. This fixed speed suits scenarios where static pressure matters more than variable control. Buyers who need PWM regulation or lower maximum airflow should look elsewhere.
Ball bearing runs at 37.5 dBA with low power draw
The ball bearing supports continuous 4300 RPM operation while keeping acoustic output to 37.5 dBA in normal use. Power draw remains modest thanks to the three-pin design and compact 15 mm motor height. Thermal performance stays consistent in restricted airflow paths typical of dense component stacks.

Questions about this item
At 4300 RPM, how much air does this 70 mm fan actually move inside a case?
The fan delivers 38.9 CFM of airflow, which is typical for a 70 mm frame running at 4300 RPM and suits tight builds where space is limited.
The 3-pin connector — does it allow speed control or is it fixed at 4300 RPM?
A 3-pin connector supports voltage-based speed control, so the motherboard can lower the RPM below the 4300 RPM maximum when less cooling is needed.
Will the 70 x 70 x 15 mm frame fit my chassis mounting holes?
Yes, the fan uses the standard 70 mm square footprint with 15 mm thickness, matching the common mounting pattern found on most cases designed for 70 mm fans.
