Common Applications
The Barrow BF04-PR is a 120 x 120 x 25 mm radiator fan on the LRC 2.0 5V platform, which combines fan power, PWM speed control and addressable RGB lighting into a single 6-pin connector. The motor draws 1.56 W and uses a fluid bearing rated at 40,000 hours, producing roughly 64.19 CFM of airflow at about 21 dBA, with peak speed around 2000 RPM (+-10%). Because the 6-pin LRC 2.0 interface is proprietary, the fan does not plug into a motherboard fan or RGB header and must be driven by a Barrow LRC 2.0 controller hub, which in turn exposes standard 5V A-RGB and PWM signals.
Frequently Asked Questions
Q: Can the BF04-PR run standalone on a motherboard fan header?
A: No. The 6-pin LRC 2.0 connector combines power, PWM and 5V A-RGB data on a single plug and requires a Barrow LRC 2.0 controller. A 4-pin PWM header alone will not power it.
Q: Is the lighting 5V addressable or 12V analog?
A: 5V addressable RGB. Connecting it to a 12V RGB header through any adapter will destroy the LEDs.
Q: What are the airflow and noise figures?
A: Approximately 64.19 CFM peak airflow at about 21 dBA, with peak speed around 2000 RPM (+-10%).
Q: What bearing does the fan use and how long is it rated?
A: A fluid (hydraulic) bearing rated at 40,000 hours.
Q: What is the fan's footprint?
A: Standard 120 x 120 x 25 mm, matching nearly all 120 mm and 240/360 mm radiators.
