What's the cool summer coming in?

In the face of the upcoming summer, I do not know if my friends have any confidence in the cooling capacity of their love machine, especially if the laptops that are accompanied by us have already started to increase in temperature and noise. In the coming short holiday, the little friends may wish to do an in-depth inspection and cleaning of the love machine to prepare for the use of the summer season.

● Blocking of cooling holes and cooling windows

Check the side of the laptop cooling window, if you find that the heat sink and the surrounding shell temperature is high, but the wind is weak or no wind, this is likely to be cooling holes, cooling windows blocked. This is a very common phenomenon, especially when some laptop users use a laptop base with a fan-type cooling fan, or if the environment is not clean enough to use, and even pets that are very vulnerable to hair loss appear almost half a year. Plug hole problem. Use a blower to blow this dust and fluff off to temporarily solve the problem. If there is obvious dust, you can use a paper clip to disperse or hook it out. If this happens frequently, you should disassemble it and clean it thoroughly.

● CPU fan failure

If the heat sink is at a high temperature, but the condition is not improved after cleaning the cooling holes and cooling windows, you should listen carefully to the internal sound. If you hear very harsh noise, or no sound at all, then the cooling fan is probably Has failed or stopped completely. There are many reasons for the failure of the cooling fan. For example, if the fan bearing is free from oil or dust, the frictional force may increase, and the fan power supply may be imaginary or missing. For fan failures, we can solve this by filling the bearings, compacting the interface and contacts, but it is best to buy a new fan replacement.

● Convection cooling holes are blocked

For some laptops that focus on thin and light notebooks, the convection cooling mode of the metal plate and keyboard is the cooling main power that is radiated by the heat pipe and the temperature-controlled fan heat dissipation. The metal plate at the bottom of the keyboard is in contact with the heat dissipation plate on the notebook motherboard, and the heat dissipation plate on the motherboard The heat is transferred to the bottom of the keyboard, and heat is dissipated through the dense “breathable holes”. If there is too much dust or grease on the keyboard, these "breathing holes" will be blocked, affecting the ability to dissipate heat. In the inspection and cleaning of many light and thin books and ultrabooks, the vent holes on the keyboard surface and its cleaning must be taken into account.

● thermal grease failure

Like the desktop computer, the heat sink between the notebook and the chip also need to use thermal conductivity materials such as silicone grease to strengthen the contact. Once the silicone grease fails, the silicone grease layer intake or poor contact, there will be fan mad turn but the exhaust temperature is not high, The notebook processor temperature is still high. In this case, we need to clean up the old silicone grease, re-uniformly spread the grease, and reinstall the heat sink. Due to the small space in the notebook, be careful when using silicone grease to reduce the amount of spillage, otherwise it is easy to contaminate the surrounding components, causing pollution and even short circuit.

● Heat pipe failure

The notebook computer usually adopts a unified heat dissipation design. Each heat chip and heat sink are connected by a heat pipe. Once the heat pipe fails, heat conduction close to the metal pipe also causes the problem of low heat dissipation efficiency. Judging whether the heat pipe is dead or not is very simple. When the lighter is used to burn one end for two or three seconds, the other end will feel hot. Then the heat pipe is no problem. Otherwise, the efficiency is too low or has failed. Heat pipe failure can only replace the entire cooling system, we need to purchase according to the notebook model.

The heat in the hot area of ​​the notebook needs to be conducted through the heat pipe to the main heat sink

After these basic tests and corresponding processing, the small companions' notebooks should provide us with calm and stable service in the cool summer. However, in the process of using the small partner should also pay attention to the operating state of the books, as far as possible prevent them from happening.
