Cooler Master MasterFan MF140 Halo Fan
Bottom line: The Cooler Master MasterFan MF140 Halo Fan ($24.99 on Amazon as of 2026-10-21 04:13 UTC): 24 individually addressable LEDs in a Duo-Ring layout, not a single hub glow; main trade-off: 140mm frame won't fit the 120mm mounts on most AIO radiators and cases.

Pros & Cons
Pros
- ✓ 24 individually addressable LEDs in a Duo-Ring layout, not a single hub glow
- ✓ Hybrid static-pressure blades built for radiator fins and mesh front panels
- ✓ Wide 650-1,500 rpm PWM range lets you idle quiet and ramp only under load
- ✓ ARGB header extender included, so you can chain lighting without extra headers
- ✓ Syncs with Aura, Mystic Light, and Polychrome Sync ARGB motherboards
Cons
- ✗ 140mm frame won't fit the 120mm mounts on most AIO radiators and cases
- ✗ Needs both a PWM header and a 3-pin ARGB header, so two cables per fan
- ✗ No sync software of its own; lighting control depends on your motherboard suite
- ✗ 1,500 rpm ceiling is modest next to high-static-pressure radiator fans
Manufacturer description
The Cooler Master MasterFan MF140 Halo brings a Duo-Ring ARGB layout to a 140mm PWM case fan, wrapping 24 individually addressable 3-pin LEDs across two illuminated rings instead of a single hub glow. That dual-ring design is the reason this fan photographs well through a tempered-glass side panel, and the included ARGB header extender means you can chain lighting without hunting for extra motherboard headers. Underneath the lighting is a hybrid static-pressure blade profile that blends an Air Balance blade with a wave-shape edge, so the MF140 Halo pushes air through the fin stacks of a CPU…
SpecPicks Verdict
SpecPicks scored Cooler Master MasterFan MF140 Halo Fan using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Cooler Master'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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will the MF140 Halo fit a 120mm radiator or case mount?
No. This is a 140mm fan and needs 140mm mounting holes. Check that your case or radiator lists 140mm support before ordering.
How many cables does each fan need?
Two: a 4-pin PWM cable for fan speed and a 3-pin ARGB cable for the 24 addressable LEDs. Cooler Master includes an ARGB header extender to help with the lighting side.
Does the lighting work with my motherboard?
It is certified for most addressable-RGB capable boards, including Asus Aura, MSI Mystic Light, and ASRock Polychrome Sync. You control it through your board's software using the standard 3-pin 5V ARGB header.
How quiet is it at low speeds?
PWM control drops it to 650 rpm at idle, and Cooler Master adds noise-reduction technology plus sound-absorbing materials to the frame. It ramps to 1,500 rpm when your thermal curve calls for more airflow.
Is it better as a radiator fan or a case intake?
Both. The hybrid static-pressure blade design is built to push through the resistance of a CPU liquid radiator or a restrictive mesh panel, which is also what makes it effective as chassis intake.
