The Gamdias NOTUS M1-1201 is a 120mm casing cooling fan built for gamers, PC enthusiasts, and system builders who want strong airflow without turning their setup into a noisy environment. With a fan speed range of 400 to 1600 RPM ±10%, it can respond to changing workloads—such as gaming sessions, heavy editing, or sustained multitasking—by adjusting performance as temperatures rise and fall. This makes it a practical choice for both everyday computing and demanding builds where stable thermals matter.
Equipped with a closed-loop control system and a 4-pin PWM connector, the NOTUS M1-1201 supports precise speed regulation through your motherboard’s BIOS or compatible fan control software. Compared to basic DC control fans, PWM-based control typically provides more consistent fan behavior across different temperature points, helping maintain a balanced cooling profile. If you’re building a quiet PC, this control approach is especially useful because it allows the fan to stay calmer at lower loads and ramp up only when needed.
This model uses a hydraulic bearing, designed to deliver long-lasting durability and steady airflow over time. For users who keep their systems running for long periods—like content creation workflows, overnight downloads, or daily gaming—bearing quality is an important factor because it can influence how reliably the fan maintains performance. The hydraulic bearing design also supports smoother operation, which complements the fan’s low-noise target.
The NOTUS M1-1201 is rated at 1.75 mmH₂O air pressure, helping it move air effectively through typical case airflow paths and radiator or vent setups where resistance may be present. At the same time, it operates at a noise level of 17 to 31 dBA, offering an ideal balance between cooling efficiency and silent performance. In real-world use, this range is well-suited for users who want noticeable cooling under load while keeping background noise minimal during lighter tasks like browsing, office work, or casual gaming.
Powered by 12V DC, the fan is designed as a straightforward plug-and-play cooling upgrade for compatible systems. Its physical size is 120 x 120 x 25mm, making it an easy fit for many ATX, mATX, and ITX cases that support 120mm fans. If you’re upgrading an older build or refreshing airflow in a compact chassis, the standard 120mm form factor helps reduce compatibility concerns and simplifies planning for intake and exhaust placement.
The Gamdias NOTUS M1-1201 comes with a 2-year warranty, giving you extra peace of mind when choosing a casing fan for your daily driver or gaming rig. For buyers in Bangladesh looking for an affordable and effective cooling improvement, this warranty coverage supports long-term ownership and helps protect your investment.
