How to install the chassis fan cooling best

Once we in the " computer Assembly Course " column for you to introduce a variety of computer assembly tutorials, rarely involved in a number of chassis cooling fan installation tutorials, for the recent netizen asked how to install the chassis fan, today's computer depth of the small compiled to share with you. For many general installed configuration, the chassis does not need to install a cooling fan is not small, but for all kinds of mainstream game computer users, in the summer is very easy to cause the internal chassis cooling, resulting in computer blue screen, crash or even burned the computer situation occurs, so the chassis cooling is also different neglect, The following small series to teach you how to install the chassis fan cooling the best, easy to help you install the chassis fan.

How does the chassis fan teach you how to install the chassis fan cooling best

　　The chassis cooling fan is not a random installation

Many computer enthusiasts think, as long as buy several chassis radiator, installed in the chassis out of the air or into the air can be, in fact, this is wrong, the installation of chassis fan also need to master skills, the technique here is refers to--chassis air duct. about what is the air duct, the wind tunnel to the computer chassis heat impact, you may wish to read under:

　　Internal structure of the chassis and knowledge of the distribution of heat sources inside the chassis

Chassis internal fans can be divided into 2 areas: one is the air inlet; The best way to install the chassis fan is in front of the chassis, or the side of the installation of 1 or 2 fans, as the inlet, and then to the rear of the chassis to install 1-3 fans as the outlet, one into a drive inside the chassis air convection, which will heat transfer out so as to achieve a good heat dissipation effect, Let's take a look at the internal distribution of the inside of the chassis:

Distribution diagram of heating source inside the chassis

As shown above, in the computer chassis, the calorific value of higher CPU area, video card area and hard disk areas, red area for high-temperature zone, that is, our CPU and power supply area. You can also see that the chassis has a front chassis fan, a rear chassis fan, a power supply fan these three locations as the main outlet, chassis fans can only be installed in these locations.

　　Single/dual fan installation schematic

If there is only one cooling fan, then we can only use a single chassis fan installation. It is not suitable to be installed behind the chassis if you want to take a single fan to draw the cold air outside the chassis. As shown above, you can also see that the airflow into the memory only went into the CPU by the power supply fan out, so the other parts did not get effective cooling, so as to not achieve the overall chassis memory temperature reduction, So this method is not reasonable. If users want to buy a single fan, it is recommended to use the form of ventilation in the front of the chassis, or the form of air supply in the back of the chassis.

If there are two of the latter two chassis fans how to install it? In fact, the two fans can be from the front of the chassis to absorb the wind and then through the rear and the power fan to send out the internal parts of the heat, the following figure:

Through the above simple fan internal air duct principle, I believe that we have some understanding of the Yu Fendao, let's take a look at the current most common three kinds of chassis wind tunnel, to see what kind of more suitable for you.

Schematic diagram of horizontal air duct of chassis

Schematic diagram of chassis stereo duct

Schematic diagram of chassis vertical duct

After reading the above classic three kinds of chassis duct schematic diagram, do you think which kind of chassis air duct heat is better? We enclose the authoritative evaluation chart of the media:

Comparison of heat dissipation between horizontal air duct, stereo duct and vertical duct

By comparing the temperature data above, we can see that the vertical duct temperature is relatively low, and it is the highest cost in these three kinds of air duct. We can sum up a few points through the above set of comparison values:

　　1. Vertical Duct Heat dissipation : from the actual effect, vertical wind duct natural heat dissipation effect does occupy the advantage. Because of such a chassis only a brand with a belief that familiar with DIY players must understand, so that the chassis of the hard disk is located on the backplane, so good cooling effect, so out of the hard disk temperature, CPU, GPU cooling effect, is really good, and better than other structural design chassis.

　　2. Three-dimensional air duct cooling needs many fans : through the above air duct diagram we can see the chassis of the 5 fan bits all use the fan, in order to build a good heat dissipation of the stereo, for the players need some cost to buy the fan, at the same time the use of multiple fans for the noise of the new pair will also be larger , which requires players to choose the fans according to their own needs.

　　3. Practical Horizontal duct : For players who choose the horizontal duct, their platform heat is not very high, and they do not need too good thermal performance. Often choose such an air duct is also from the original chassis fan to set, small white players unobstructed will use such an economical and practical wind tunnel.

　　PostScript Language : Introduced here, this article is basically over, don't look just a small chassis fan installation, but it hides a lot of knowledge principle, novice friends can not be belittled, how according to their own computer situation, to install chassis fan, to achieve the most suitable for their own heat dissipation mode is the best, Not necessarily choose the best heat dissipation, but should be based on the characteristics of their own computer to choose the cooling air duct, blind pursuit of high heat dissipation will also cause unnecessary waste, is not advisable, I believe that reading this article will choose the most suitable for their own chassis heat duct installed.
