Why does the chassis still get hot when an ultra-thin cooling fan is installed?clip fan manufacturer

　　A personal computer generates a lot of heat when it is running. If the heat cannot be discharged from the case, it may cause the computer to malfunction or even damage the internal structure. Faced with this situation, everyone generally installs ultra-thin cooling fans. But sometimes it is found that the chassis with the ultra-thin cooling fan is getting hotter and hotter. Why is this?

　　The direction of the chassis fan blowing is very important, and the wrong installation will have the opposite effect.

　　According to the author's personal experience, after installing a fan, the heat dissipation performance of the host has not improved or even worsened. Most of this is because the fan is installed in the opposite direction. The side panels of the mainstream chassis now like to use transparent materials. Generally, only the front, top and back have large heat dissipation holes. Therefore, the three-dimensional air duct design is generally used, that is, the air intake is from the front of the chassis, and the air is drawn from the top. and the back to exhaust the heat (layered design, the heat of the power supply and hard disk is exhausted from the bottom surface). The installation of a fan is to accelerate the air circulation in the chassis to improve the cooling efficiency. It can be seen that in order to establish a reasonable and efficient air duct, the blowing direction of the chassis fan is very important. If the fan is installed in the opposite direction, it will cause the air duct in the chassis to be disordered: the hot air in the chassis was only discharged at a slow speed, but now it cannot be discharged at all. It was more difficult to dissipate heat in summer. More prone to overheating.

　　It is not difficult at all to distinguish the direction of the fan. Experienced players know it, but obviously many novices and novices still do not know, and these problems occur. We feel that it is necessary to say this again: everyone only needs to look at the side of the fan with the beam as the air inlet, and the side with the beam and the wire as the air outlet. In the specific operation, the side of the fan on the front panel with the beam and the wire should face the inside of the case, and the side of the fan on the top and the back with the beam and the wire should face the outside of the case, just keep this in mind. If you encounter the problem that the temperature of the host with the fan is still very high, then it is recommended that you disassemble the chassis to see if the fan is blowing in the wrong direction. Generally speaking, after correct installation, you will find that the temperature of the chassis should have dropped significantly, and the problem of high host temperature can be solved. The side with the brand LOGO without the beam is the air inlet, and the side with the beam is the air outlet

　　In addition, everyone should also note that the blowing direction of the radiator fan also affects the heat dissipation of the chassis. The side-blown radiator has a larger area of cooling fins, a large number of heat pipes, and better cooling effect with a fan. Therefore, most air-cooled radiators on the market adopt a side-blown design. Using a side-blown radiator is equivalent to adding a fan in the middle of the case. The blowing direction of this fan will also affect the air duct of the case. Specifically, in the three-dimensional air duct case mentioned above, the radiator fan should also be consistent with the air duct of the case, that is, blowing air toward the back of the case, and moving in other directions will cause the air duct to be disordered and affect the heat dissipation effect of the case. If you use a water-cooled radiator, you need to pay attention to the blowing direction of the cold exhaust fan, which is determined according to the installation position of the cold exhaust.

　　The side-blown radiator is equivalent to adding a fan to the chassis, so pay attention to the wind direction of the fan

　　PS: Do not forget to clean the chassis when installing a fan

　　The purpose of installing a fan is to improve the air circulation in the chassis, but after the chassis is used for a long time, it will inevitably encounter the situation that the heat dissipation holes are blocked by dust, which will also affect the heat dissipation effect. Especially players who have cats and dogs at home, this problem will be more serious. Therefore, in order to have good heat dissipation performance of the chassis, in addition to installing more fans, it is very necessary to clean the heat dissipation holes of the chassis before every summer. When buying a case, you can buy a product with a heat dissipation hole with a removable dust filter, which is more convenient to clean up at ordinary times.

　　The fan speed can't come up, in fact, it is not adjusted well

　　In addition to the reverse installation of the chassis fan, there is another situation that players often encounter: even if the heat in the chassis is heavily accumulated, and the temperature of the CPU and graphics card remains high, the fan has been kept at a low level "not too fast". Speed, why is that?

　　This is not because there is any problem with the fan, but now many chassis have added the function of adjusting the speed of the fan or the fan has the function of adjusting the speed of the fan. The original intention of the manufacturer is to achieve controllable cooling performance and noise through the fan speed adjustment function, but it only requires players to manually operate. That is to say, when the temperature inside the chassis is high, it must be set to a high speed to improve the cooling performance, and when the temperature is low, the fan speed should be reduced to obtain a quieter experience.

　　When the fan speed is low, you should check whether there are buttons, knobs, etc. for speed adjustment on the chassis. If there is, set the fan speed to high, then you will find that the noise of the fan has increased significantly. The cooling performance also improved.

　　There is a threshold for new cooling technology to play well, which requires players to set precise settings

　　We have introduced to you before that many of the latest motherboards have joined the black technology of playing fans. They are connected to the chassis fan, graphics card fan and water cooling fan by adding a 4pin socket, and then intelligently control various fans through software. In order to ensure the accuracy of temperature monitoring, the motherboard is also equipped with multiple temperature detection points to provide all-round cooling support for the whole machine.

　　These control functions do not mean that the fan should be plugged in. First of all, the chassis fan should choose a product with temperature control function, so as to ensure that the temperature control function is supported. Secondly, after installation, it is necessary to enter the corresponding software to set, you can choose to adjust the fan speed according to the data of a temperature detection point on the motherboard as a reference. The speed of each fan can also be precisely adjusted. For example, after the temperature reaches a certain value, the fan is set at a fixed speed, thereby realizing intelligent control of temperature and speed.

　　In addition to the motherboard, many high-end chassis also have fan controllers. The powerful CAM controller can control parameters such as the light color of the light strip and the fan through the CAM software dashboard, which is very simple to operate.
