"Computer" is an indispensable product in our work and life. Although the use rate of "mobile phone" is higher at present, we can never deny the glory of "computer". When it comes to "computers", I always have a little pride, because my computer has never had blue screen, crash and other problems in the past 20 years, and the host hardware has never broken. I think all this is due to my efforts in computer maintenance. In terms of software, I will reinstall the system at the latest 3 months. You can also do this part of work by yourself. You only need a USB flash disk with startup function; In addition, in the hardware part, I often clean the dust inside the chassis, timely replace the CPU heat sink, clean the dust on the video card fan and dust in the host power supply, and regularly clean the dust Replacing the heat sink can make the computer run faster and more stable. Recently, I was lucky to be qualified for the evaluation of the "overclocking 3 dragon subduing" heat sink. Taking this opportunity, let's talk about the CPU heat sink today.

I believe everyone knows about the famous brand overclock 3. Its radiator products cover high, medium and low grades. The author will temporarily position this "Dragon Subduing" in the middle grade. The price of "overclocking 3 reduces dragon" JD is 129 yuan. For mid-range CPU radiators, the price is moderate. Let's take a look at the outer packaging, and it is also reasonable.

After unpacking, it can be seen that the internal space is divided into two parts: heat sink and fan blade, of which the fan blade is also mixed with some small accessories.

The fan blade of "overclocking 3 dragon subduing" is quite large. The four wire plug means that the fan blade supports automatic speed regulation, which is also called silent fan. From the appearance alone, the fan blade part of "Overfrequency 3 Dragon Subduing" is quite solid in terms of workmanship. Looking at the fan blades carefully, we can see that the "Overfrequency 3 Dragon Subduing" has a light effect design. When the device is turned on, the light will light up. However, the author is worried about whether it will bring light pollution. Later, we will take a closer look at the experience part.

"Overfrequency 3 Dragon Subduing" mainly adopts nickel plated heat pipe cooling mode in the heat sink part. Four nickel plated heat pipes with strengthened fins can effectively enhance the heat dissipation performance. It is worth mentioning that fin fin of radiator adopts FIN technology. The author has checked the official description information. Officially speaking, using this technology can reduce the wind shear noise and enhance the heat dissipation performance. I will test this in the follow-up experience.

There are two unique designs of the "Overfrequency 3 Dragon Subduing" heat sink. One is that there are three raised metal blocks on the bottom of the heat sink, which mainly play a fixed role; Secondly, a gap is reserved at both ends of the side of the radiator. At first, I didn't understand what it was for. When I installed it, I knew it was for the convenience of fixing the operation window reserved for the radiator.

Let's have a picture of the whole family without installation instructions! The fastener accessories of "Overfrequency 3 Dragon Subduing" are more than 50 in size. They look very complex, but the actual operation is relatively simple. The four black screws are used to fix the fan blades, so we can throw them away first. The first three items in the first row are accessories for the AMD architecture motherboard. In fact, the key is the third widget. The author will not repeat it, because there are detailed illustrations in the instructions.

The computer motherboard needs to be removed during installation, which is the first time that the author has removed the computer so loosely in so many years.

The installation part is simplified by the author. As can be seen from the figure, the author has installed the fixed base part of "Overfrequency 3 Dragon Subduing", and the direction arrow on the metal sheet should face the CPU when installing, so the installation is correct! The fixed nuts need to be tightened by the small class hand provided by the official, so that the top nut can be fastened.

Then we apply the thermal conductive silicone grease on the CPU, and try to apply it evenly. Then put the radiator on it, press it slightly, and then take it up to see how they fit. If you install it in place, the thermal conductive silicone grease at the bottom of the CPU and the heat sink is a whole piece, as shown in the figure.

After placing the "Overfrequency 3 Dragon Subduing", the author checked the space. The heat sink is a certain distance from the capacitor. Although the surrounding space is slightly compact, there is nothing wrong with it.

When fixing the "overclocking 3 dragon dropping" heat sink, you can see the role of the two reserved operation windows, especially the side next to the main board heat sink. If there is no such reserved operation window, it will be very troublesome to fix the screws.

The last part is to install the fan blade, which is fixed on the "overclocking 3 dragon subduing" heat sink with four black screws.

After installation, through a simple test, it is confirmed that the "Overfrequency 3 Dragon Subduing" works normally. At this time, we can see that its light has been turned on. When the light is turned on, its light is not dazzling.

When the lights are turned off, the light effect of "overclocking 3 dragon subduing" does not bring the so-called "light pollution" to the author, which I prefer. In addition, this light has only one color, which I think is very good. It's a bit annoying to flash around.

When there is no case, the author tested the noise level when it runs with a mobile phone. From the photos, we can see that the noise value of "Overfrequency 3 Dragon Subduing" is only 44dB when there is no case, which is already a very low sound. If the case cover is properly handled, I believe the noise value is only about 30dB, which is very good.

After the simple test, the author installed the motherboard and other accessories back to the computer. After starting up, we can see that the "overclocking 3 dragon subduing" light in the chassis will not affect our use at all, which should be emphasized.

The computer was assembled in 2010. As the author said at the beginning of the article, I have maintained the computer well all the time. Is there any obvious change in this computer before and after the replacement of "Overfrequency 3 Dragon"? We speak with data.

Before replacing the "Overfrequency 3 Dragon Subduing", the author made a temperature and pressure test with Master Lu. When the test lasted for two minutes, it ended because the graphics card temperature was too high. At that time, the CPU temperature was also 77 ℃. After replacing the "Overfrequency 3 Dragon Subduing" radiator, what would be a huge change in the test effect of this computer again?

It can be seen that after nearly 3 minutes of testing, the CPU temperature of this computer was only 56 degrees Celsius at the highest after replacing the "overclocking 3 dragon subduing" radiator. The previous test was more than 20 degrees Celsius worse, which really satisfied me. Careful partners will find in the data that the number of revolutions of the "Overfrequency 3 Dragon Subduing" was only about 2000 revolutions at that time, which means that in that operating state, the number of revolutions is still not high, so that no huge noise will be generated. I think this should be attributed to its 12cm large volume and nine leaf silent flow guide design.

Experience summary

After several days of experience, I personally feel that the performance of "overclocking 3 dragon subduing" is very good both in terms of process design and heat dissipation effect, and the mute effect is also very good! Relatively speaking, I am a thrifty person. When I change the radiator, I will consider a very practical problem, that is, the cost. The market price of the 12cm fan blade equipped with "Overfrequency 3 Dragon Subduing" is also very easy to accept. If you have strong hands-on ability, you can change the fan blade regularly! If you are more frugal than me, you can clean the dust of the fan leaf, and it will be OK to use it continuously for half a year.
