Our Take

Best for: PC builders looking for a reliable 140mm fan with bright ARGB lighting.

The Cooler Master MF140 Halo² is a 140mm fan built for PC builders who want both performance and looks. Its main draw is the dual-ring ARGB lighting, which is noticeably bright and diffuses well through the frosted blades. The larger fan blades do help move air, making it a solid choice for case airflow or as an addition to a cooler.

What stands out is the PWM control. You can set it to run very quietly at low speeds or ramp up to 1600 RPM when your system needs more cooling. The hybrid frame is supposed to help with stability, though the fan feels quite heavy, which might be a concern for some mounts.

The limitation is its size and weight. At 140mm, it won't fit in all cases, and the heft means you need to secure it well. For the sale price, it's a good value if you specifically need a 140mm fan with reliable lighting and adjustable performance, but it's not a revolutionary upgrade from other decent fans.

Price Analysis

At $19.99, this fan is 26% off its typical $26.90 price. The 30-day and 90-day averages are around $26.80, so this is a significant drop. While we don't have an all-time low for comparison, this price is well below its recent selling point, making it a good time to buy.
