Trailing edge serrations might be increasing the boundary layer to decrease flow separation. If laminar flow is disrupted at the leading edge, the performance compromise can lower the sound volume at the trailing edge. Too much propeller speed creates shearing and noise in the trailing edge. Or perhaps it makes no difference which side they are on, as along as the are present on one or the other (.or perhaps it is only to try and separate themselves from the vast sea of same old, same old, fans).The leading edge serrations are done to decrease air flow, the trailing edge to increase it, imo. On the Akasa fan, do you think the serrated leading edge created a different sound profile as claimed? For a company like Noctua that focuses on obsessive levels of silence/performance R&D (not saying that in a bad way at all) it makes me wonder why they only choose the trailing edge. Franzen4RealGenuinely curious to see a comparison done between these and the Arctic P12.
Now did that actually work, I haven't seen the evidence.
#Fluctus 120 pwm free
WirkoDo I want my case fan to be my shrink in his free time? Sure I do!We used to heal the insane with ornamental fountains in history. Included 40 cm cable extension provides installation flexibility even in voluminous cases.
The fan is equipped with a 4-pin power cable with a built-in splitter, allowing users to connect another fan to the same power and speed control source. Enthusiasts can even create custom semi-passive cooling systems thanks to a fan stop feature: Fluctus 120 PWM automatically stops when PWM signal falls below 5% duty cycle and automatically restarts when it rises above 10%. Fluctus 120 PWM is ready for all of them. Case fans, water cooling radiators and air coolers all require different fan speeds to reach a balance between performance and noise levels. The speed of Fluctus 120 PWM fans can be controlled by the PWM signal in a wide range from 300 (☑00) to 1.800 (☑0%) rpm, making them suitable for various usage scenarios. All-axis vibration dampeners built into the fan frame reduce the risk of vibrations in adjacent elements without breaking compatibility with standard 120 mm fan placements. It is the heart of Synergy Cooling's patent-pending psychoacoustic optimization and makes Fluctus 120 PWM even more pleasant to the human ear than it is apparent from standard noise level measurements. Serrated leading edges of the fan blades reduce prominent tonal noise, easily discernible over the acoustic background. Compared to other popular solutions, replacing intake fans with Fluctus 120 PWM can reduce video card and CPU temperatures by between 1 and 4 ☌ while reducing noise levels by up to half perceived loudness.įluctus 120 PWM fans provide excellent acoustic performance thanks to technical improvements developed by Synergy Cooling. Thanks to all-round optimization, Fluctus 120 PWM can also create high airflow in less restricted applications, such as in cases with dense dust filters. Thanks to the wide speed regulation range from 300 (☑00) to 1.800 (☑0%) rpm makes Fluctus 120 PWM a perfect match for both bigger (360 mm) and smaller (240 mm, 120 mm) radiators, which usually requires higher fan speeds. In addition to that, the overall noise levels are decreased. Users can expect a 1 to 3 ☌ reduction in temperatures compared to other fans commonly paired with AIO liquid coolers. It provides high static pressure, which is required for creating good airflow through dense radiators of all-in-one water coolers. SilentiumPC Fluctus 120 PWM is equipped with a unique 9-bladed rotor with serrated leading edges.
A revamped, durable fluid dynamic bearing (FDB) with 100.000-hour MTBF ensures high longevity, underlined by the 6-year manufacturer's warranty. It provides outstanding performance on dense water cooling radiators and in cases that are equipped with dust filters. The Fluctus 120 PWM fan is co-developed with Synergy Cooling and features high static pressure, very good airflow and excellent acoustics.
