Why are you different with the same lights? How to select an appropriate RGB fan for the chassis?

In addition to the performance of accessories, many DIYers have begun to consider the issue of lighting. In particular, the side transparent or even full transparent chassis has become the mainstream, and fans without lights are worth buying for nothing? But it is also learned to purchase accessories such as RGB fans a main board The interface of is not corresponding. Light means that the light effect is not synchronized, and heavy means that the light cannot be turned on directly.

Since there are so many lights in the chassis, let's take a look at their principles first. First of all, the light effects of the motherboard and memory are controlled by the motherboard's SMBus, such as ASUS AURA SYNC Shenguang synchronization, MSI Mystic Light and Gigabyte RGB Fusion are all operated through SMBus bus, so remember to install SMBus drive By the way, I will also install light control for you Software 。

If you want to achieve the light synchronization with the motherboard, you need the RGB of the accessory to support the linkage operation with the motherboard. For example, the memory and graphics card that support Shenguang synchronization, RGB Fusion can be seen in the control software, and the linkage or separate light settings can be set. In addition, control software from different manufacturers also supports light synchronization of different protocols. For example, ASUS AURA SYNC can realize light linkage including keyboard, mouse and even router.

For separately purchased RGB fans, we should think about the effect it can achieve. The simplest one is the single effect, which is directly connected to the fan interface of the motherboard. Some products are connected to the SATA interface or the four pin D-type hard disk power interface. Of course, such fans are also the cheapest, but the lighting effect cannot be controlled.

The advanced RGB fan is equipped with a controller that also receives power from the SATA interface or the four pin D-type hard disk power interface. Some products can provide multiple light outputs. This RGB fan can set a variety of light effects. There are buttons on the controller to switch, and even adjust the brightness of the light. In addition, some players have arranged light strips inside the chassis, which is often the same wiring method. However, such products are rare on the market, and are commonly found in some chassis with light strips and fans.

Next is the fan that can synchronize with the RGB light effect of the motherboard. Here we need to pay attention to the type of light effect interface supported by the lower motherboard. Early motherboards often used 12V 4pin sockets, and gold plated cylindrical cross-section pins were used to distinguish them from the fan and I/O panel wiring. It should be noted that this 12V 4Pin is controlled by an analog signal. The four Pin is the simplest "red, green and blue+common ground". The three color light beads can be adjusted by the control software of the motherboard. Such fans are inexpensive, but the disadvantage is that they can only display the same color at the same time.

The newer mainboards all use 5V 3Pin digital signal sockets and comply with the WS2812B specification. The 3pins are 5V positive pole, digital signal and ground wire respectively. The mainboard sends out signals continuously according to the specified time sequence. The lamp beads of the fan can show the dynamic effect like a movie. It also supports more lamp beads, which can show up to 16.7 million colors, And it can be linked with the light effect of the motherboard to achieve a uniform effect, of course, the price is more expensive.
