Single 140 mm ARGB case fan

The Cooler Master MasterFan MF140 Halo² White is a 140 mm case fan designed for chassis intake or exhaust, liquid-cooler radiators and air-cooler heatsinks. It uses a 4-pin PWM connector for 0 to 1600 RPM speed control and a 3-pin addressable RGB header for dual-loop lighting effects. The rifle bearing and Air Balance blades deliver 59.51 CFM at a rated 27 dB(A).

Builders who want a white 140 mm fan

This fan suits builders who need a single white 140 mm unit with addressable RGB and PWM control for case, radiator or heatsink mounting. It is not for systems that only have 4-pin RGB headers, for installations that require a different frame thickness, or for buyers who need a multi-fan kit in one package.

140 mm frame with 25 mm thickness

The fan measures 140 by 140 by 25 mm, so it fits standard 140 mm mounting holes with 25 mm clearance. Verify that your case, radiator or cooler accepts this exact frame size before purchasing.

Questions about this item

Will the 4-pin PWM connector on this fan plug directly into my motherboard CPU or chassis fan header?

Yes, the fan uses a standard 4-pin PWM connector that fits any motherboard 4-pin fan header for speed control from 0 to 1600 RPM.

Can I daisy-chain the 3-pin ARGB lead of this fan with older 3-pin ARGB strips I already own?

The fan includes an extended 3-pin ARGB plug designed for daisy-chaining, so you can link it with other 3-pin ARGB devices on the same header.

How do I confirm the dual-loop ARGB lighting is running in Gen 2 mode after I connect the 3-pin header?

When the 3-pin ARGB header is connected, the onboard auto-detection enables full Gen 2 customisation via motherboard software; if the header is unplugged the fan falls back to a default spectrum pattern.
