Zyvpee 3007 12 30mm sleeve bearing 12V transparent case fan

Compact 30 mm transparent fan

This Zyvpee 3007 12 case fan measures 30 mm square by 7 mm thick and runs on 12 V through a two-wire DC connector. Its transparent frame and sleeve bearing suit small-form-factor builds and custom 3D-printed GPU shrouds where space is at a premium. The fan delivers a quiet 25 to 30 dBA noise level without any LED lighting. It is aimed at hobbyists who need a tiny, unobtrusive airflow source for tight clearance zones.

Replaces stock 30 mm coolers

The unit serves as a direct drop-in for noisy or failed 30 mm fans on CPU coolers or experimental graphics-card ducts. The jump is worthwhile when the original fan exceeds 30 dBA or when a transparent blade matches a see-through build theme. Builders who require PWM speed control or a three- or four-pin header will not find that functionality here. The two-wire design limits automatic motherboard regulation to voltage control only.

Limited by two-wire DC interface

The 12 V two-wire connection provides power and ground but no tachometer or PWM signal, so the motherboard cannot monitor RPM or adjust duty cycle. Speed changes rely solely on varying the supply voltage, which may not be supported by all fan headers. The sleeve bearing offers quiet operation at low speeds but can wear faster than ball bearings in continuous high-RPM use. No mounting hardware or adapters are included in the package.
