Compact 70 mm 4-wire case fan

This 70 mm square fan fits tight server and workstation chassis where space is limited. It runs on 12 V DC and draws 2.46 W through a standard 4-wire connector that enables PWM speed control. The 25 mm thickness matches the common slim profile used in 1U and 2U enclosures.

Ideal for density-optimised builds

Suits integrators populating rackmount servers, blade enclosures or compact industrial PCs that require 4-wire PWM regulation. Not for builds that can only mount larger frame sizes, nor for headers limited to 3-pin voltage control.

Questions about this item

What are the mounting hole dimensions for the PF70251VX-Q02U-S99 70x70x25mm fan?

The fan measures 70mm by 70mm with a 25mm thickness, matching standard 70mm case fan mounting hole spacing.

How do I connect the 4-wire PWM cable correctly on this 12V server cooler?

Align the keyed 4-pin connector with the motherboard or controller header; forcing it backwards bends pins and disables speed control.
