Compact 40 mm cooling fan

The Zyvpee THA0412AD is a 40 mm by 20 mm case fan designed for tight spaces such as router enclosures or small-form-factor CPU coolers. It runs on a 12 V supply drawing .6 A and uses a standard 4-pin connector for PWM control.

Ball-bearing build with four-wire control

A ball bearing supports the rotor for durable operation in continuous-use scenarios. The 4-pin header delivers both power and speed feedback, allowing the host system to regulate fan speed automatically based on temperature.

Replaces noisy or failed 4020 units

This fan serves as a direct drop-in replacement for worn 40 mm x 20 mm coolers that have become loud or stopped spinning. The upgrade is worthwhile when the original unit lacks PWM control or uses a sleeve bearing that has dried out.

Questions about this item

What does the 4-pin connector on this fan control?

The 4-pin connector provides power and a PWM signal so the motherboard can vary the fan speed precisely.

How much clearance does the 40x20mm frame need inside a case?

It requires a 40mm by 40mm mounting hole pattern and 20mm of depth behind the mounting surface.

How do you orient the 4-pin plug when installing the fan?

Align the keyed tab on the connector with the notch on the motherboard header and press straight down until it clicks.
