What the b-Shark 120mm fan delivers

The BGears BG01794 is a single 120mm case fan built for chassis intake or exhaust. Its 15-blade impeller and fluid dynamic bearing target high airflow at a rated 26.5 dBA, suiting builders who want stronger cooling without a loud system.

Practical limits of the 3-pin interface

The 3-pin power connector allows voltage-based speed control but lacks the fourth wire required for PWM regulation. Motherboards that only support 4-pin headers will run the fan at full 1500 RPM unless voltage control is available in BIOS or via a hardware controller.

Deciding spec: 82.6 CFM at 1500 RPM

This airflow figure determines whether the fan moves enough air for your thermal load. If the chassis or radiator needs more than 82.6 CFM, a higher-RPM or larger-diameter model is required; if the noise budget is tighter than 26.5 dBA, a slower fan should be chosen.

Questions about this item

How do I decide between the 120mm 25mm thick model and a thinner fan?

The 25mm thickness fits standard 120mm mounts; choose it when your case or radiator has the full depth available.

What does the 82.6 CFM rating mean once the fan is installed?

At 1500 RPM it moves 82.6 CFM of air, delivering strong case or radiator airflow while the fluid dynamic bearing keeps noise to 26.5 dBA.

What does the 3-pin connector limit in practice?

The 3-pin connector provides voltage control only, so speed varies with motherboard voltage regulation rather than PWM duty cycles.
