How to identify the thermal performance of a laptop

The most direct way is to boot up and run some large software, and after a period of time, touch the bottom of the notebook and the heat dissipation vent with your hands, and feel the temperature of the level, although the method is dirty, but the most effective. But in reality, when purchasing, you can't always try to run each one to compare, we can judge the heat dissipation effect by observing the emissions of several large heating users of the notebook.

The heating "masters" of notebooks mainly include: CPU, battery, hard disk, and PCMCIA slot. The author estimates that many people know the first three things, but why are PCMCIA slots also included in the "blacklist"?

When we use this interface device, such as network card, moden, 1394 adapter, card reader, etc., the PCMCIA device generates a lot of heat. After inserting the network card and using it for a period of time, the temperature will be around 60 degrees, and it feels very hot when you take out the network card. No wonder there is such a warning on the notebook manual: "After unplugging the PCMCIA device, do not touch the interface part to prevent burns".

Therefore, when we buy and sell notebooks, we can pay attention to the internal structure design to roughly know the quality of heat dissipation in the future, these parts can be seen from the different panels at the bottom, and the design of placing these large heating households separately is designed to widen the distance between them as much as possible. Then the heat dissipation is definitely better than the relatively concentrated. Just imagine, if the CPU, power port, hard disk, and PCMCIA slots are relatively close, think about the four big households "working" at the same time, then it will definitely become a "flame mountain".

Then the performance of the notebook must be affected to varying degrees.

Therefore, when buying a notebook, as long as you pay attention to whether its internal structure is reasonable, run some large software on the spot, and measure the temperature of the fuselage by hand, you can roughly know how good the heat dissipation is. Because it has a close relationship with heat dissipation.

You can use Master Lu or other detection software to check the temperature of the current CPU and graphics card, and the temperature will rise significantly when running large programs; At present, laptop heat dissipation mainly uses copper tubes to dissipate heat, and copper pipes are used to conduct heat until the fan is discharged. Upstairs said that the graphics card with a fan is a desktop machine, and the graphics card on the laptop is actually a chip.

Summary. At present, the mainstream notebook cooling system is a heat dissipation base, which aims to improve the heat dissipation effect by raising the notebook and increasing the wind power.

Hello dear, please wait a minute.

Hello dear, judging the heat dissipation of a notebook should be judged from two aspects1Heat dissipation hardware configuration 2Thermal testing.

What are the mainstream cooling systems on the market and which one works best.

The heat dissipation test can be divided into these several square clusters of knowledge 1Full load CPU temperature, power consumption, Xi Zhengna frequency 2Single-bake CPU temperature, single-bake graphics card temperature 3Test the surface temperature of the notebook. Includes keyboard, wrist rest.

Hello dear, please wait a minute.

At present, the mainstream notebook cooling system is a heat dissipation base, which aims to improve the heat dissipation effect by raising the notebook and increasing the wind power.

As long as it is not used in a high-temperature environment and with high loads for a long time, the effect of the heat dissipation base is still okay.

At present, there are also heat dissipation bases with liquid cooling mode, and the effect is not too different from <> air-cooled base

There is one more problem.

Dear dear, please say <>

It is to use a notebook in life, an external graphics dock and a desktop display, so that it can be used as a desktop.

Use is usable.

However, compared with desktops, the performance release of CPUs and graphics cards will be more conservative.

If you use it to design or play games. The same configuration is not as effective as a desktop <>

Is there anything that needs special attention or defects in the use process?

There is no special place, it is all the same, oh dear <>

It's just that the size is different, and the performance release is not the same<>

Won't this put a little more load on the notebook?

No, pro, electronic devices are produced to be used.

Okay thank you.

Notebook I'm not afraid of bad performance, I'm afraid that the temperature is too high to drop, especially in the hot summer, how can this book be less about the topic of heat dissipation, but a good notebook heat dissipation system starts from itself. Let me teach you how to test the thermal performance of the notebook.

Laptop heat dissipationPerformance testingMethod:

Material is everything.

Generally speaking, a large number of material problems should be considered for heat dissipation, and the shell material should be better to choose alloy as much as possible, while the traditional ABS plastic.

The heat dissipation is a bit worse.

Notebook internal channel.

The position design of the internal units can form a good air duct and a good ventilation duct to form a sufficient space for heat dissipation and heat dissipation.

Location of heat dissipation holes.

This is mainly to take into account the user's feelings, because our mouse interface is on the right, so if the air outlet of the notebook is also on the right, wouldn't it be a bad effect, who can accept the summer to be hot air.

What about blowing? Touch the body to feel the temperature.

Generally, there will be prototypes in stores around the clock for customers to try. We can touch the keyboard, palm rest, bottom, and heat dissipation holes to feel the temperature of the keyboard, and the temperature that the hand can't feel is about 25; There is a feeling of temperature around 35 degrees; Warm, that is, quite warm, should be around 45; Hot but still continuous contact should be around 55; I feel hot, but I can still endure the temperature for three to five seconds, so it should be around 70.

1. You can use notebookhardwarecontrol test software to understand the temperature of the CPU and hard disk in real time, and you can use copy software such as SETI to pull the CPU load rate to 100%, and continue for a period of time, and then measure the temperature.

The function of the heat sink is to absorb this heat and then dissipate it into or out of the chassis to ensure that the temperature of the computer parts is normal. Most heat sinks absorb heat by contacting the surface of the heat-generating parts, and then transfer the heat to distant places, such as the air inside the case, and then the case transfers the hot air to the outside of the case to complete the heat dissipation of the computer.

There are many types of heatsinks, CPUs, graphics cards, motherboard chipsets, hard drives, chassis, power supplies, and even optical drives and memory will all need heatsinks, and these different heatsinks cannot be mixed, and the most common contact is the CPU heatsink.

Depending on how heat is taken away from the radiator, the radiator can be divided into active and passive cooling. The former is commonly used for air-cooled radiators, while the latter is common for heat sinks. Further subdivision of heat dissipation methods, it can be divided into air cooling, heat pipe, liquid cooling, semiconductor refrigeration, compressor refrigeration, etc.

Generally, the heat dissipation of the notebook is on the side, and the heat dissipation is normal! If it's underneath, it's better to buy a radiator!

The next Master Lu is the previous Z** that can detect the temperature of the CPU and hard disk, and the heat dissipation of the general ASUS notebook is good, and the hard disk can reach 7200 rpm.
