Compact 40 mm PWM fan for tight CPU coolers

The Zyvpee TFB0412EHN is a 40 mm square frame fan with a 28 mm thickness, designed to fit slim tower or low-profile CPU coolers where larger fans cannot mount. It runs on 12 V and draws 0.87 A through a standard 4-pin PWM connector for speed control. Dual ball bearings support continuous operation in confined airflow paths.

Replaces worn 40 mm cooler fans with 4-pin control

This unit directly substitutes an aging or failed 40 mm fan on an existing heatsink that uses a 4-wire header. The upgrade is worthwhile when the original fan has developed bearing noise, reduced RPM or lost PWM response. Matching the 40×40×28 mm footprint and 4-pin pinout ensures mechanical and electrical compatibility without adapter cables.

Suits builders repairing

It serves technicians restoring OEM coolers, DIY builders adapting slim heatsinks, or anyone needing a non-LED 40 mm PWM fan for a specific mounting pattern. Buyers who require higher static pressure at larger frame sizes, RGB illumination, or 3-pin voltage control should look at other models.

Questions about this item

Will the 40×40×28 mm frame fit my CPU cooler's mounting holes?

The fan measures 40 mm square by 28 mm thick, so it matches coolers designed for that exact footprint.

How do I connect the 4-pin PWM lead without reversing the polarity?

Align the keyed 4-pin connector with the motherboard or controller header; the notch prevents backward insertion.

When should I plan to replace the dual-ball-bearing assembly?

Dual ball bearings typically last several years of continuous use; replace the fan if noise or vibration increases noticeably.
