Product Identity

The BGears b-BlasterPWM 90 is a 90 mm case fan built around a dual ball-bearing motor and a four-pin PWM controller. It targets system integrators and enthusiasts who need high airflow in a compact frame for small-form-factor or densely packed builds.

Suitability

This fan suits builders who want a wide 1200 to 5000 RPM range and strong static pressure up to 12.0 mmH2O for restrictive radiators or heatsinks. It is not for buyers who need a larger frame size, integrated lighting or silent operation at low loads.

Decisive Specification

The 90 mm frame with 118 CFM maximum airflow and a 6.24 W power draw at 0.52 A determines fit. Verify that your case or cooler mounts accept a 90 x 90 x 25 mm unit and that your fan header can supply the required current.

Highlights

  • High airflow of 118 CFM for strong case cooling
  • Wide PWM speed range from 1200 to 5000 RPM for flexible control
  • Dual ball bearing design for durable long-term operation
  • Peak static pressure of 12.0 mmH2O handles restrictive airflow paths
  • Compact 90 mm frame fits tight build spaces

Questions about this item

How do I mount the 90mm frame and connect the 4-pin PWM header without reversing the wire order?

Align the four 90mm mounting holes with the case or radiator, secure with the supplied screws, then plug the 4-pin connector into the motherboard PWM header so the keyed notch matches — the fan will not spin if the plug is seated backwards.

When will the dual ball bearings need replacement?

The 2 ball bearing design is rated for continuous operation at up to 5000 RPM; under typical case airflow loads expect several years before audible wear appears, at which point the entire fan unit is replaced.

At what static pressure does airflow start to drop off during sustained high-RPM operation?

Maximum static pressure is 12.0 mmH₂O; beyond that point the 118 CFM airflow curve declines sharply, so the 12.0 mmH₂O limit is the first constraint you hit under sustained load.
