70 mm PWM case fan for compact cooling
This 70x70x25 mm fan runs on 12 V and draws 3.7 W through a four-wire PWM connection. It fits standard 7025 mounting points in small-form-factor chassis or on low-profile CPU coolers. The new unit is ready for immediate installation.
PWM control is the deciding specification
The four-wire interface lets the motherboard vary speed automatically, so the fan stays quiet at idle and ramps up only when temperatures rise. Buyers whose boards lack a PWM header cannot use automatic speed control and should choose a three-wire alternative instead.
Highlights
- Precise speed control via 4-wire PWM
- Compact 70x70x25mm frame fits tight spaces

Questions about this item
What does the 3.7 W power draw mean for my fan header?
The fan draws 3.7 W at 12 V, so it stays well within the typical 1 A limit of a standard motherboard header.
What does the 4-line PWM connection actually control?
The fourth wire carries the PWM signal that lets the motherboard vary speed precisely, while the third wire reports the current RPM back to the BIOS.
