What causes an overheating CPU graphics card?

Poor contact of the radiator, altered air duct, low wind power of fans (including power supply, CPU, and graphics card fans), dirty and blocked radiators, poor contact of buckles, no thermal grease or uneven coating or too much coating, and long-term high-load work will all lead to excessive temperature.

1. Check whether your u has been overclocked, and go back to COMS to restore the initial value.

2、Kyushu Fengshen Beta200st Fan heat is not very powerful,It is recommended to use overclocking three Red Sea Extreme Edition140 or so,You can also consider adding a fan on it,Mine is two fans,CPU is AMD631X4 is used by him,CPU temperature does not exceed 70°,Graphics card HD6790R temperature does not exceed 70°,Including playing large-scale 3D games。 Hey...

The heat dissipation effect of the fan you change should be good, whether you have a good silicone grease wipe, and whether there is too much dust inside the air intake, air outlet and power supply of the case, and whether the air duct of the case is not blocked well will also affect the CPU and graphics card. If not, consider adding a case cooling fan.

If the heatsink and case are fine, then there is a possibility that there is a problem with the CPU. The 7750 consumes a lot of electricity and heat, and it is speculated that after two years of use, it will age seriously and may be close to the end of its life. Of course, it's just speculation, if you have the conditions, you can try it again.

If you feel that the temperature is high, you can try a new fan!! After all, the old fan has been in service for 2 years

If you use it again, it is generally safer to use it at 75°.

First of all, I will tell you that adding a cooling base has little effect, and it will only blow more dust into the inside of the machine anyway. Another point is that during the operation of the laptop, the fan does not rotate all the time like a desktop, and only turns when the temperature reaches a certain height, and the higher the temperature, the faster the rotation. Your Sunburst C466A is a discrete graphics card, so it's normal for the temperature to be a little hotter.

When you clean the fan and heat sink, you must clean it, and when you apply silicone grease, it should not be too thick, otherwise it will affect the heat conduction. The installation of the heat sink should be screwed diagonally, and after the four screws are installed, remember to tighten them. The heat dissipation of the graphics card of this machine is particularly large, my friend's is the same as your machine, after I help him deal with it, the boot temperature is generally around forty or fifty degrees, you try again according to my method.

Upstairs, I added: Oiling the fan, do you think the fan is a leather shoe? The fan in the notebook is strictly forbidden to fill the oil by itself, otherwise the excess oil dripping onto the motherboard will burn the motherboard, and it will also make the fan absorb more dust, resulting in more difficult cleaning of the fan page, don't answer blindly if you don't understand, alas。。。

It's okay to buy a radiator, which is generally in the 60 to 100 plus.

It would be better to buy a heat sink, which can be reduced by about 5-10.

The fan has not been maintained, so you can maintain the fan first.

An external fan is a must, and at the same time, you have to consider whether there is too much ash in the inner box, and if you can't clean it, go to the repair shop to clean it all at once, ** It's not very expensive. By the way, you can oil your fan, so that the effect will be better. Also, try not to open large programs at the same time, so that the CPU and the burden will be relatively large, and the temperature will naturally increase greatly.
