AC-powered 90 mm case fan

The BGears b-Blaster-AC 90x38 is a single 90 mm by 38 mm case fan that runs directly from 100-125 V AC mains. It spins at 2700 RPM with a tolerance of ±10% and delivers 62 CFM of airflow at a noise level of 36.7 dBA. The frame is heavy-duty cast aluminium and the motor uses a dual ball bearing for extended life. Impedance protection prevents overheating if the rotor stalls.

Check voltage and mounting space

Verify that your installation can supply 100-125 V AC power and that the chassis has a 90 mm fan mount with 38 mm clearance for the thick frame. The package includes two finger guards, a 4 ft US two-prong AC cord, an open wire lead and a screw set with 60 mm screws, nuts and washers. No onboard speed controller is present so plan for external switching if variable speed is required.

Suited for high-static-pressure cooling

This fan suits industrial enclosures, server chassis or ventilation projects that need strong airflow from mains power and can tolerate 36.7 dBA. It is not for builders who want a quiet desktop fan, for systems limited to 12 V DC headers, or for mounts thinner than 38 mm.

Questions about this item

What is included in the package and what must I buy separately?

The box contains the 90 mm × 38 mm fan, two fan guards, a 4 ft USA non-polarised AC power cord, a 2-pin open wire lead and a screw set with four 60 mm screws, nuts and washers. No separate mounting hardware is required for standard case installation.

How do I choose between the 80 mm, 90 mm and 120 mm versions of this series?

Select the size that matches your case mounting holes: 80 mm for 80 mm cut-outs, 90 mm for 90 mm cut-outs and 120 mm for 120 mm cut-outs. All three share the same 38 mm thickness, 2700 RPM speed, 2-ball bearing and 100–125 V AC operation.

What does the 62 CFM airflow figure mean when the fan is running inside a real PC case?

At 2700 RPM the fan moves 62 CFM of air through an unrestricted opening; inside a case the actual flow will be lower due to grille, filter and component resistance, while the 36.7 dBA noise level is measured at one metre in free air.
