Compact 90 mm PWM case fan

The BGears b-PWM 90 Blue is a single 90 mm case fan built for systems that require a slim 25 mm profile. It uses a dual ball bearing rated for high speed operation and a 4 pin PWM connector that also fits 3 pin headers. Fifteen translucent blue blades and matching blue LEDs give a distinctive look while moving air through tight spaces.

Suited for small form factor builds

This fan suits builders working in compact cases or upgrading legacy chassis that only accept 90 mm mounts. The 500 to 4000 RPM range lets the motherboard balance airflow against noise automatically. Buyers who need higher static pressure for dense radiators or heatsinks should consider alternative designs.

88 CFM maximum airflow

At full speed the fan delivers 88 CFM while producing 39 dBA, a level that remains audible in quiet rooms. The 10 percent RPM tolerance means actual peak flow can vary slightly between units. If your thermal target demands more airflow than 88 CFM at 90 mm, this model will not meet it.

Perguntas sobre este artigo

Does my case have a 90 mm mounting area for this fan?

The fan measures 90.00 x 90.00 x 25.00 mm and includes four screws, so it fits any standard 90 mm case opening.

Will the 4-pin PWM connector work with my older 3-pin motherboard header?

Yes, the fan ships with a 3-to-4-pin Molex adapter and can also plug directly into a standard mini 3-pin header.

How can I confirm the fan is running within its 500 to 4000 RPM range after installation?

Check the RPM reading in BIOS or monitoring software; it should stay between 500 and 4000 RPM with a tolerance of ±10 %.
