90 mm 38 mm High-Speed PWM Fan

The BGears b-BlasterPWM 90x38 is a 90 mm case fan with a 38 mm thick frame. It uses a Japanese dual-ball bearing and a 4-pin PWM connector for automatic speed control. The unit ships without any LED lighting.

Suited for Tight High-Pressure Cooling

Builders who need strong static pressure in a 90 mm mount will benefit from the 0.17 to 17.16 mmH2O range. Buyers who need a slimmer frame or lower maximum noise should look at other models.

500 to 5000 RPM Speed Range Decides Fit

The wide 500 to 5000 RPM span lets the fan drop to 10.4 CFM for quiet idling or reach 128 CFM under load. Match this range to your thermal curve to decide if the part fits.

Questions about this item

Will the 90 mm by 38 mm frame fit my case's 90 mm mounting holes?

The fan measures exactly 90 x 90 x 38 mm, matching the standard 90 mm hole pattern used on most cases.

How do I connect the 4-pin PWM connector so the motherboard controls speed from 500 to 5000 RPM?

Plug the 4-pin PWM header into a CPU or chassis fan header on the motherboard; the fourth wire carries the PWM signal for automatic speed control.

When should I expect to replace the Japanese 2 ball bearing?

The dual ball bearing is rated for extended lifespan at high speed; replace only if noise rises above the rated 57.2 dBA or rotation becomes uneven.
