Manufacturer description
The Bgears b-PWM 80mm Red LED fan is built for small cases, older towers and rear exhausts that still use 80mm mounts and need more airflow. It spins from 500 to 4000 RPM and moves up to 78 CFM at full speed, which is a lot of air for an 80x80x25mm frame. The fan uses a mini 4-pin, 4-wire PWM connector that plugs straight into your motherboard fan header. Your BIOS or fan-control software can then read its speed and adjust it. Under light loads it can idle near 500 RPM, and when temperatures climb it ramps toward 4000 RPM. Bgears rates the noise level at 37 dBA. Nine translucent red blades…
SpecPicks Verdict
SpecPicks scored Bgears b-PWM 80mm Red LEDs Gaming PC Cooling Fan using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Bgears's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How much airflow does the Bgears b-PWM 80mm fan move?
It is rated for up to 78 CFM at its top speed of 4000 RPM. Airflow drops as the fan slows toward its 500 RPM minimum.
Can my motherboard control the speed of this fan?
Yes. It uses a mini 4-pin, 4-wire PWM connector that plugs directly into a motherboard fan header, so the board can monitor RPM and adjust speed between 500 and 4000 RPM.
How loud is the Bgears b-PWM fan?
Bgears rates the noise level at 37 dBA. Real-world loudness depends on how fast your motherboard runs the fan, and it will be quieter at lower PWM speeds.
What size is this fan, and will it fit my case?
It measures 80x80x25mm, so it fits standard 80mm fan mounts. Check that your case or bracket has 80mm mounting holes and at least 25mm of clearance for the frame depth.
What color are the LEDs, and what voltage does the fan use?
It has red LEDs and 9 translucent red blades. It runs on 12VDC. The listing does not mention separate lighting control, so expect a fixed red glow.
