Elfidelity PC Filter 4Pin Fan Power Noise Filter Power Purification PC-HiFi 

Introduction
PC Hi-Fi Fan Interface Online Power Filter Purification Isolation The filter adopts a bidirectional filter ground wire isolation design, which isolates the harmonic interference of the fan motor to the entire PC power supply environment and avoids the interference of the fan motor clutter to other devices in the PC. Especially in the PC audio field, which is very sensitive to clutter, you can get immediate results by eliminating ripple interference. A good internal power supply environment has positive benefits for the stability of all electrical equipment. (PC power supply has always been the short board and drawback of PC Hi-Fi)

The "fan" mentioned here is narrow in scope to "PC fan", and only refers to the "fan" that supplies power inside the PC. DC power supply, the general working voltage is between 3V-12V, the speed is 400-5000 rpm, the size is usually within Φ200mm, and the current is within 2A. Regardless of power consumption or size, the fans used in our PCs belong to the little guy in the fan category. DC motors do not need to study the advantages and disadvantages, life or efficiency of brushes and brushes like AC motors. Over the years, PC fans have basically not played any tricks, at most ball bearings, liquid bearings or something, or golf-faced blades. Of course, in fact, such a simple and mature structure does not have much new ideas to hype. If it must be classified, it is divided into 2pin, 3pin and 4pin through the tap (socket). The interface modes are all up and down compatible. That is, the 2pin fan can be plugged into the 4pin interface. The 2pin is generally a constant speed fan, and it is a DC motor inside, and has no other functions. 3pin has one more speed test. 4pin and one more PWM pulse speed regulation (actually it doesn't matter whether it is a stepper motor or not, there are many adjustment methods).

 

 

 

 


Compared with hard disk motors, PC fan motors have basically negligible power supply quality requirements. This thing is 10 rpm faster, 100 rpm faster, or 50 rpm slower, and it doesn't matter. The speed is basically within 2500 rpm, because of the noise of the violent fan above 3000 rpm, I can't stand it anyway. The hard disk motor, 7200 rpm is the usual speed, SAS easily up to 15,000 rpm. Therefore, for the fan, filtering is not necessary for its protection, but to prevent it from harming other hardware.

The 4Pin interface fan isolation filter is not the first creation of Elfidelity, but the works of the predecessors are relatively simple, lacking rigorous design, excellent materials, and reasonable structure.
 The Fan Power Noise Filter from Elfidelity's Small Wind Sugar adopts the design idea of two-way independent parallel filtering and isolation, step-by-step filtering, and selects the Japanese Ina ELNA red robe fever audio, and cooperates with the Japanese Ruby RX30 professional Power filter capacitors, together with polymer solid capacitors, Philips BBC metal film capacitors, and TDK high-power inductors create an excellent two-way filter, which can effectively isolate the impact of the fan motor on the internal power grid of the PC, purify the PC power supply, and ensure that the PC audio environment.

There is also a blue LED on the Small Wind Sugar, it is not a decorative vase, it serves as an indication of the working condition of the Fan Power Noise Filter isolator. If the LED is obviously flickering or pulsing off. It shows that the interference generated by the fan is greater than the maximum margin that Small Wind Sugar can smooth out the peak burr. If this happens, I highly recommend not to use this fan, because its interference is too great, which may not only seriously affect the stable work of your PC, but also damage peripheral precision electrical equipment, such as hard drives.

The installation of Small Wind Sugar is very easy. It comes with a self-adhesive backing and comes with a 30cm 4pin twisted snake mesh cable. It can be installed freely, and it is convenient for cable management and routing. The only thing that needs to be reminded is that Small Wins Sugar is an isolated design, and the input and output are directional. The power supply must be connected to the "IN" interface and the fan connected to the "out" interface, otherwise the fan will not work.
