80 mm PWM case fan for compact builds

The BGears b-BlasterPWM 80x38 is an 80 mm square frame fan designed for cases with 80 mm mounting points. It targets builders who need active airflow in small-form-factor enclosures or legacy chassis where larger fans will not fit. The single unit uses a 4-pin PWM connector so the motherboard can regulate speed automatically.

Installation fits standard 80 mm holes

Four mounting holes match the 80 mm pitch used on most cases and radiators; the 38 mm thickness requires enough clearance behind the mounting surface. The 4-pin PWM header plugs directly into a motherboard fan header — no adapter is needed. Builders should verify that their case or radiator allows 38 mm depth, otherwise the frame will foul adjacent components.

500–5000 RPM speed range defines cooling capacity

The fan spins from 500 to 5000 RPM, delivering 6.4 to 108 CFM of airflow and 0.14 to 13.96 mmH2O of static pressure at a maximum of 55.3 dBA. This wide range lets the same fan run quietly at idle and ramp up for heavy loads. Buyers who need lower noise at full speed or higher static pressure for dense fin stacks should look elsewhere.

Questions about this item

How do I confirm the 4-pin PWM fan is responding correctly after installation?

Enter the BIOS or fan-control software and verify the reported speed moves smoothly between 500 and 5000 RPM as the temperature changes.

What comes with the b-BlasterPWM 80x38 and what must I supply myself?

The package includes the single 80 mm fan with a pre-attached 4-pin PWM connector; you only need a motherboard 4-pin header or a compatible fan controller.

Should I choose the 80 mm 38 mm thick model or a thinner variant for my case?

Select this 80 x 38 mm version when the mounting area has 38 mm clearance and you want the full 500-5000 RPM range delivering up to 108 CFM.
