The Gamdias Notus M1-1201 ARGB has been profiled as a budget alternative 120mm fan designed to appeal with its modular features. A key standout feature is its blade design, which includes both forward and reverse blades in the box. This allows users to easily swap between them depending on whether they require intake or exhaust airflow. The unit also incorporates addressable RGB lighting, connecting via a standard 3-pin 5V header.
The fan operates within a speed range of 400 to 1600 RPM. Its technical specifications include a maximum airflow rating of 57.56 CFM and a static pressure of 1.75 mmH₂O, which makes it viable for both standard case ventilation and integration with radiators or heatsinks.
Construction details point to the use of PBT material for the fan frame, noted for its durability in electronics. The opaque blades contribute to diffusing the RGB illumination. Wiring features a 4-pin PWM cable equipped with a daisy-chainable tail, enabling multiple connections from a single motherboard header. For connectivity, the ARGB uses a 3-pin 5V link compatible with other linked devices.
While functional, the build quality received mixed feedback. Reviewers pointed out excessive flex in the plastic frame and blades, along with a noticeable wobble during rotation. The overall finish was described as typical of budget fans, lacking the confidence found in more expensive models.
Performance testing yielded varied results. At peak speed, the fan recorded 50.5 dBA, placing it slightly quieter than both the Noctua NF-A12x25 G2 and Phanteks D30-120. However, when tested at a normalized speed of 1400 RPM, it measured 48.2 dBA, making it louder compared to competitors which recorded 45.2 dBA (Phanteks) and 45.6 dBA (Noctua).
Furthermore, in noise-normalised thermal testing at 40 dBA, the Notus M1 displayed a drop in performance relative to more efficient options. CPU and GPU temperatures ran several degrees warmer than those recorded by Phanteks, Noctua, and Sudokoo alternatives.
The review concluded that the Gamdias Notus M1 ARGB is intended for budget builds or users seeking basic ARGB lighting without significant expenditure. Priced at roughly £12-£13 per fan (or £33.75 for a three-pack), it offers good value, particularly due to the inclusion of swappable blades.
However, potential buyers should note that while adequate for budget applications, its thermal performance is unremarkable, and its noise levels are not comparable to premium fans at normalised speeds. The unit is summarized as being unable to compete with higher-priced models in areas such as ultra-low noise operation or top-tier cooling capacity.
