Frequently Asked Questions - CF-140-PRO-RGB LC-Power
How do I control the RGB lighting on the CF-140-PRO-RGB?
The fan uses a standard 3-pin ARGB connector. Connect it to a compatible motherboard header (5V) or use the included RGB controller to sync with your system. For motherboard control, enable RGB software like ASUS Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light, or ASRock Polychrome.
What is the maximum fan speed and noise level?
The fan speed ranges from 800 to 1500 RPM via PWM control. The noise level is between 15 and 28 dBA, depending on speed. Higher speeds provide more airflow but increased noise.
Can I use this fan on a radiator?
Yes, the CF-140-PRO-RGB is suitable for use on radiators up to 140mm. It comes with screws for mounting. Ensure your radiator has standard 140mm fan spacing (124.5mm screw holes).
How do I clean the fan?
Turn off the PC and disconnect the fan. Use a soft, dry cloth or a can of compressed air to remove dust. Avoid using water or cleaning liquids, as they may damage the bearings or RGB components.
Does the fan support daisy-chaining for ARGB?
The fan comes with a single 3-pin ARGB cable. If you need to chain multiple fans, you can use a splitter cable (not included) that connects to the motherboard or controller. Ensure the total current does not exceed the header limit (usually 3A).
What is the airflow rating of this fan?
The fan delivers up to 55 CFM (cubic feet per minute) at maximum speed. This provides effective airflow for case cooling or radiator use.
Is the fan compatible with 3-pin fan headers?
The fan has a 4-pin PWM connector. It can be plugged into a 3-pin header, but PWM speed control will not work; the fan will run at maximum speed. For variable speed, use a 4-pin PWM header.
My RGB lights are not working. What should I check?
First, ensure the ARGB cable is connected to a 5V header (not 12V RGB). Check motherboard software settings and update drivers. If using a controller, verify it is powered and the mode is set. Try a different ARGB port.
Can I reverse the airflow direction?
The fan is designed to push air in one direction (indicated by arrows on the frame). To reverse flow, you can mount the fan on the opposite side of the case or radiator. The blade design is not reversible.
What is the warranty period for this fan?
LC-Power provides a 2-year warranty against manufacturing defects. For warranty claims, contact your retailer or LC-Power support with proof of purchase.
