heat! Just one word! With the arrival of summer, the temperature of the author's royal capital has also reached nearly 40 degrees Celsius. Dear Gamer not only suffers from physical suffering, but even the game equipment is painfully squatting. The cart is swaying with sweat. There is no bitterness. Some players can feel the heat waves around them even if they fight with air-conditioning. It seems that this touching temperature comes from the roaring computer host.
Lazy is the source of all evil! Lazy not only allows you to become fat paper, but also allows your combat equipment to die. Dust pollution is not only the environment, but also quietly invade your computer host. If you are not the main ash handling host, then in the depths of the host can not be seen, has long been dominated by dust, a little bit Corruption of its fighting power, until one day will be lifelong because of your laziness.
Boards that have accumulated all year are like artifacts
Inside the computer case, due to long-time operation, inadvertently accumulated thick dust. These dust particles are stuck on the cooling fins and fans of various hardware, resulting in uneven thermal conductivity of the heat sink and poor heat dissipation. This is probably the same as the principle of scaling in the kettle, but heat dissipation is a reverse engineering. Loose dust adheres to the heat sink, allowing the heat to accumulate on the surface. The powerful fan can't blow it away.
The most efficient fan dust removal
The task of clearing the ash is still annoying, especially the chassis that hasn't been cleaned in years. It's not an exaggeration to say that it is plugged. After blowing with a fan, you need to use a small, soft-bristle brush for each cooling fin. Clearing between the gaps in the sheet is actually the source of all evils that cause heat accumulation. To resist the infringement of dust, it is necessary to do preventive work in addition to timely cleaning. The first is the environment, dusty environment will undoubtedly increase the accumulation speed of dust, there is a plot of the use of the environment in terms of dust is also very important, and then is to the chassis with a dust filter, can effectively prevent dust from entering Quantity, as long as it regularly cleans the air filter.
A lot of players care about their own equipment, and often do a quick cleaning of their interiors. They can clearly clean the inside of the chassis, but the temperature is still higher than it is? Add so many fans or useless, really angry baby friends ! According to the inertia of thinking, the more fans are blowing the heatsink, the better, how can they not rise or fall?
Feel the chaos from the chassis duct
Actually not, adding more N fans to blow the radiator can increase the local air flow, in theory, can effectively improve the cooling effect, the chaos of the air duct determines that the hot air is always circulating in this space, Coupled with the loss of efficiency conversion, this is bound to be a vicious cycle.
Air duct schematic
Most of the chassis now support wind tunnels. In fact, the performance of the original hardware radiator is sufficient to dissipate heat. The continuous circulation of hot air blown out is the fundamental reason for the temperature surge. Reasonably use the position of the fan's fan and the direction of the wind, use routines to export the hot air that is accumulated inside the chassis. However, the specific air duct mode must be carefully planned and set according to different chassis.
Silicon grease is the most important and most insignificant heat exchange medium between heat sink and heat source, and many matters will have a decisive effect on heat exchange. Because silicone grease is exposed to the air for a long time, the raw materials will inevitably oxidize with time. Although the most important part is the fastener is pressed tightly on it, the surrounding gap is always the air Locally, if your chassis has heat dissipation problems in many cases, you may be wondering about the aging of grease. Please refer to the oil grease separation rate for this performance.
Already failed silicone grease
The application of silicone grease is also closely related to the heat dissipation effect. The thermal conductivity of silicone grease is generally around 4.5-7.5, and the base of copper radiator is 401. The gap in thermal conductivity is so disparity, it is also destined that silicone grease is used as an auxiliary thermal medium. The presence. The thickness of the grease application is, of course, the thinner the better, and then the uniformity of the application and the contact area of ​​the heat sink and the heat source.
The main components of liquid metal thermal grease are:
As technology continues to advance, the heat transfer medium is not limited to the type of grease. The thermal conductivity of silver-containing silicone grease can be about 8 to 8.5. Only excellent silicone grease can achieve a thermal conductivity of 7.5. Currently more expensive and difficult to use is the liquid metal, its thermal conductivity can reach 127, the main component of which is metal tantalum, but tantalum's thermal conductivity is only about 40, do not know that the liquid metal declared as high as 120 + thermal conductivity is used What technology, assuming liquid metal thermal conductivity of only 40, is also much higher than the ordinary thermal grease.
The author's friend's computer was placed in a corner, often at a high load, and the fan turned very annoying. So the wonderful work put a bunch of books on it. Not to mention that the noise in the resonance of the chassis was significantly reduced, but the problem came along. The air flow in the corner was originally poor, and the “insulation layer†was covered. The temperature was a touching one.
Editing Xiaobin is dustproof in this way but it will be removed when used.
Many people who place the chassis on the ground will habitually regard it as a rack, layered on top of the chassis like a thick quilt, and the temperature is kept in the chassis without reservation. This situation is rare, most people are for dust and beauty, placed on the surface of the dust cloth, the chassis on both sides and there is no heat vent is better, if the fan is blocked, the effect will be greatly reduced .
Platform full nude is also a solution
The dust on the chassis is of course very important. Adding a dust filter on the air inlet of the fan is just fine. Never use it as a rack or cover a very thick object to affect heat dissipation. Long-term high temperature of the hardware will accelerate the aging of the components, which will shorten the life span, and even severely damage the hardware.
Everything about the chassis itself is finished. If the other points mentioned above are resolved, please do not ignore the last one. The environment in which the chassis is located is also crucial. After all, the heat emitted by the hardware will eventually have to be dissipated. It is also necessary to maintain good ventilation in the room or a lower temperature.
Industrial notebook plus small swimming pool is the best solution
When the author was still a new person, he put the computer under his feet and bought it without moving. It was lying there quietly and the room was also air-conditioned, but it was just that the heat screamed from under the feet. Hey, the air under the table has no mobility at all. At the end of the day, the window of a software's temperature warning cuts out the game. Only when the hardware is ready to boil, the chassis is placed in a place with good air flow. It's necessary, and you don't have to sweat with yourself either.
Air-conditioned summer is quite the same for the soothing computer
The hot summer is the peak period of computer “onsetâ€. Everyone does not want the computer to suddenly take the opportunity to clear up the internal dust, and do a good job of various preventive measures in order to ensure that the computers that accompany their battles are protected from high temperatures. , stable and efficient operation is based on a good environment, players suffering from high temperature trouble, quickly hands-on personal computer to do it!
