SilentiumPC Presents the Innovative Fluctus 120 PWM Fan with Psychoacoustic Optimization

[btarunr]

SilentiumPC, the European manufacturer of CPU coolers, Power Supply Units and PC cases, introduces the new Fluctus 120 PWM axial fan as a stand-alone product for the DIY market. The Fluctus 120 PWM fan is co-developed with Synergy Cooling and features high static pressure, very good airflow and excellent acoustics. It provides outstanding performance on dense water cooling radiators and in cases that are equipped with dust filters. A revamped, durable fluid dynamic bearing (FDB) with 100.000-hour MTBF ensures high longevity, underlined by the 6-year manufacturer's warranty.

SilentiumPC Fluctus 120 PWM is equipped with a unique 9-bladed rotor with serrated leading edges. It provides high static pressure, which is required for creating good airflow through dense radiators of all-in-one water coolers. Users can expect a 1 to 3 °C reduction in temperatures compared to other fans commonly paired with AIO liquid coolers. In addition to that, the overall noise levels are decreased. Thanks to the wide speed regulation range from 300 (±100) to 1.800 (±10%) 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.



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. Compared to other popular solutions, replacing intake fans with Fluctus 120 PWM can reduce video card and CPU temperatures by between 1 and 4 °C while reducing noise levels by up to half perceived loudness.

Psychoacoustic optimizations
Fluctus 120 PWM fans provide excellent acoustic performance thanks to technical improvements developed by Synergy Cooling. Serrated leading edges of the fan blades reduce prominent tonal noise, easily discernible over the acoustic background. 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. 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.

Versatile PWM control
The speed of Fluctus 120 PWM fans can be controlled by the PWM signal in a wide range from 300 (±100) to 1.800 (±10%) rpm, making them suitable for various usage scenarios. Case fans, water cooling radiators and air coolers all require different fan speeds to reach a balance between performance and noise levels. Fluctus 120 PWM is ready for all of them. 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%. 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. Included 40 cm cable extension provides installation flexibility even in voluminous cases.

MSRP: 10.90€ including VAT.

Akasa has been making similar fans since as far back as 2013 but nobody ever talks about them.

That might be akasa's fault, as they haven't done much marketing for their products for a very long time.
I used to review a lot of their products back in the day and had a really good relationship with them and still try to catch up with the one guy I still know there when we happen to be at the same trade shows.
They actually make some rather good products, but they're too low key.
I guess it doesn't help that the UK seems to be their main market. Can't even buy their stuff in Taiwan, despite it being a Taiwanese company...

That's some grade A marketing wank

I think most fans nowadays have that type of dents in the blades, yeah.

Do I want my case fan to be my shrink in his free time? Sure I do!

And the only spec shown is the RPM range. I know paper specs don’t tell the whole story but, seriously? A whole essay and nothing about CFM or mmH2O.

Psycho-acoustic = crazy sounds.

I have 3 of these in my case really good fans

So the acoustic improvements are just in their minds not actually applied to the product.

Props for those mad google skills professor.

Uh what are those fans exactly? As far as I know every brand AIOs usually use their own very different fans lol

Strange, normally the number of blades is a prime (to generate less harmonics).

Genuinely curious to see a comparison done between these and the Arctic P12.

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. 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).

We used to heal the insane with ornamental fountains in history. Now did that actually work, I haven't seen the evidence.

The leading edge serrations are done to decrease air flow, the trailing edge to increase it, imo.

Too much propeller speed creates shearing and noise in the trailing edge. If laminar flow is disrupted at the leading edge, the performance compromise can lower the sound volume at the trailing edge. Trailing edge serrations might be increasing the boundary layer to decrease flow separation.
