Introduction

Shenzhen Chaopin Three Technology Co., Ltd. is a leading national high-tech enterprise in the industry, integrating the R&D, production and sales of radiators. This company provides global customers with efficient silent cooling solutions in PC personal computers, LED lamps and other fields, as well as comprehensive and considerate after-sales services. Overfrequency III Technology has a number of sharp patented heat dissipation technologies, such as HDT heat pipe direct contact technology. Now this technology has been applied to many high-end radiators.

The overclocking three U-4D dragon reducing CPU radiator is a professional CPU heat pipe mid end radiator newly developed by the overclocking three technology. In terms of structure, this radiator subverts the design of traditional radiator fins directly contacting the heat source, and boldly adopts the scheme of suspending the fins. Only four 6mm pure copper nickel plated heat pipes support the fins and fans, and four heat pipes constantly and evenly guide the heat source generated by the CPU to the suspended fins, Then a 12mm downforce fan is used for heat conversion. Although this slightly thin design is exquisite and compact, it does not take up space, but it will make people wonder whether this design can bring good heat dissipation effect? This time I got it with this question Love to play computer games Try this product provided by the platform, install it into my computer, and find out the answer.

Product unpacking and appearance

I am an old user of the overclocking three radiator, because I have used an overclocking three water cooling radiator for nearly two years. This water cooling radiator I use is the most popular classic water cooling radiator of the overclocking three - Julang 120. The price of this water cooling radiator is less than 200 yuan, but it can bring excellent heat dissipation effect, Under the protection of this water-cooled radiator, the temperature of my computer is stable below 30 ℃ all the year round.

Dragon Subduing Radiator is a new series of radiator products newly developed by Hyperfrequency III Technology. The price of this U-4D Dragon Subduing CPU radiator I got this time is about 100 yuan, which is also inexpensive. The product information on the front and back of the package of this product is very rich. The design features and technical composition of this radiator are introduced respectively. The HDT heat pipe direct contact technology, FIN button technology and the use of four high-efficiency nickel plated pure copper heat pipes make people feel that this is a very reliable heat dissipation product.

Open the package and take out the protagonist of this product. The fin area of this radiator is not large, and the width is about the same as my open palm, which is fairly standard. The use of FIN technology keeps the spacing of these fins consistent, allowing the airflow generated by the fan to pass through evenly and smoothly, not only reducing the wind cutting noise, but also enhancing the overall heat dissipation performance of the radiator.

It can be seen from the side that four nickel plated pure copper heat pipes with a diameter of 6mm pass through the middle of each radiator. The heat pipe and the fin fit closely without gaps. This process is called the fin threading technology, which allows the heat pipe to pass through the fin directly by mechanical means. The contact surface between the heat pipe and the fin section is almost identical to welding, which can effectively improve the heat dissipation performance while reducing the thermal resistance.

There are many bumps on the side of each fin of the overclocking three U-4D dragon subduing CPU radiator. It is said that this design is also to increase the wind area and make the heat dissipation more efficient.

Because the HDT heat pipe direct contact technology is used on the contact surface between the heat pipe and the CPU of this radiator, it can be seen that the pure copper heat pipe is closely bonded with the aluminum heat sink block through a fine polishing process, so that the copper and aluminum atoms are connected to each other to some extent, eliminating the thermal resistance and greatly improving the heat conductivity of the radiator.

Despite its small size, the overclocking three U-4D radiator uses many cooling technologies. Of course, in addition to the heat sink, the overclocking three U-4D is also equipped with a 12mm giant fan. The rated voltage of this fan is 12VDC, which belongs to DC power supply, and it also has an intelligent stepless speed regulation function. The speed regulation range is 1000-1800RPM ±% 10 RPM, and the fan speed will be adjusted in real time according to the heating condition of the CPU.

From the side where the fan contacts the cooling fin, the nine blades of the fan have many guide grooves. This design can accurately locate the wind direction, so that the wind generated by the fan hydraulic bearing can efficiently press on the cooling fin. In addition, the noise generated by the fan hydraulic bearing is extremely low, only 18-25dBA, and this bearing can keep the fan stable when rotating at high speed.

Now, all computer accessories have entered the era of playing with lights, and this product of Overfrequency III is no exception. The outer edge of the fan of Overfrequency Sanjianglong U-4D is also embedded with a circle of blue LED lights. When the fan works, the LED lights will turn on accordingly. The lights are beautiful and not dazzling, and they can always remind themselves whether the fan works normally.

Fan installation process

The overclocking three U-4D dragon subduing CPU radiator supports multi platform installation, so it provides a wealth of screws, brackets and other accessories. In fact, only about two-thirds of them are actually used. The main motherboard platforms supported by this radiator are:

Intel Platform: LGA2066，LGA2011，LGA1366，LGA115x，LGA775

AMD Platform: AM2/AM2+、FM1、FM2、AM3、AM4

Therefore, before installing the fan, be sure to read the installation instructions of the heat sink carefully and find out which platform your motherboard is on.

My computer case is a relatively old standard ATX case, which was found at a computer store in SEG Computer City for 90 yuan (excluding power supply). The motherboard backplane of this chassis is a whole steel plate, so when I install the high-speed three water cooling fan and the overclocking three U-4D air cooling fan, I must remove the motherboard from the chassis. The cheap design of the chassis pit makes me have to remove it often. Alas, so much dust has accumulated in the chassis!

Before dismantling this super frequency three billows 120 water-cooled radiator, which has accompanied me for many days and nights, I took a special close-up of it. I will take it down later. I still can't bear it. The two aggressive black thick rubber pipes of water cooling are also covered with a thick layer of ash, which will be cleaned up later.

First step of fan installation . After removing the dusty computer motherboard, I used a cotton swab dipped in anhydrous alcohol to carefully wipe the front and back of the motherboard, which consumed half a bag of cotton swabs. How laborious! After the mainboard is cleaned, the first step of fan installation begins. I took out the 3M PC insulation sheet in the package and stuck the side with adhesive tape on the CPU welding position. This insulating sheet produced by 3M Company is very thick, and it seems that the insulation performance is not bad. The reason why this radiator is equipped with this PC insulation sheet is that the support backplane in the accessory is a whole stamping steel plate, conductive! Therefore, it is very necessary to do a good job in insulation.

Step 2 of fan installation . Continue with installation. Because the metal backplane provided in the accessories is dual-use, the installation direction of the backplane needs to be selected according to the model of the motherboard. My motherboard is an AMD platform, so I choose the side of the backplane engraved with the word "AMD" to stick closely to the computer motherboard. After selecting the direction of the backplane, follow the radiator installation instructions and put the four screws marked G through the backplane, Then put on 4 hard rubber pads marked with I respectively, and this step is completed.

Step 3 of fan installation . Insert the backplane with screws and rubber pads into the four holes on the back of the motherboard. At this point, the third part is complete, and the installation steps on the front of the motherboard are left.

Step 4 of fan installation . At this time, the installation on the back of the motherboard has been completed. From this step, you can enter the installation process on the front of the motherboard. This step is very simple, just put the remaining four rubber pads marked as I on the instruction manual on the four screws protruding from the front of the motherboard, and then proceed to the fifth step.

Step 5 of fan installation . This step is to screw the 4 studs marked H in the fan installation manual onto screws G. Note that the size of the openings on both sides of the H stud is different, and the end of the large opening should face the motherboard. After the studs are tightened by hand, they need to be tightened and reinforced with the help of the wrench provided in the packaging box. In my experience, it is only necessary to tighten a finger gently without turning the wrench. Don't be aggressive. Remember!

Step 6 of fan installation . Install the fastener. This radiator provides AMD and Intel two sets of fasteners. My motherboard is AMD platform, so I choose AMD fasteners. There is an arrow on each fastener, and the arrow must face the CPU. Then screw the four nuts marked L in the instruction manual on the protruding screws, and then find a cross screwdriver to tighten the nuts. Pay attention to the force, and repeat again. Never use brute force!

Step 7 of fan installation . At this point, the main body of the fan and the CPU are launched. This step is also very simple. Just clean the fan base and the CPU surface, and put the CPU into the CPU socket in the correct direction. Pay attention to the number on the fan base. Each fan has a unique number.

Step 8 of fan installation . Apply thermal conductive silicone grease. In fact, there is no technical content in the work of applying thermal conductive silicone grease. The fan base does not need to be applied, just apply the thermal conductive silicone grease to the central position of the CPU surface. When installing the radiator, the radiator base will evenly squeeze the silicone grease to the position around the CPU. If you are not confident, you can also use a cotton swab and other tools to remove the spilled thermal conductive silicone grease. The amount of thermal conductive silicone grease supplied with the radiator is relatively small, only enough for one use, but the quality is good.

Step 9 of fan installation This is the most critical step. Find the fixing fastener marked D in the installation manual from a stack of accessories, as shown in the following figure, place the fixing fastener on the upper edge of the radiator base, let the hollow position of the fastener be embedded on the module protruding from the middle of the upper edge of the radiator base, and then screw the fixing fastener onto the protruding screw of the AMD fastener with the spring nut marked K. Note that there are two types of spring nuts: long and short. On the AMD platform I installed, the shorter one is needed. The process of fixing the spring nut with a cross screwdriver requires a little skill. It is best to use the alternate tightening method. One nut is tightened one circle, and then another nut is tightened. It is OK to feel that the radiator cannot be rotated by hand. The tension of the spring itself plays a role in preventing loosening. Therefore, it is not necessary to tighten too many cycles to avoid crushing the CPU.

Step 10 of fan installation . This is the last step of this fan installation. The front and back sides of the four corner threaded holes of the overclock three U-4D dragon subduing CPU radiator fan are cushioned with thickened damping rubber pads. After the fan is installed, it can effectively reduce the vibration and noise generated by the fan operation, and the damping rubber pads can also increase the stability of the fan rotation. The installation process in this step is very simple. Just fix the fan to the heat sink with the four black fan screws marked F in the manual. Because the two fasteners of the heat sink to fix the fan are moving parts, so the four corners of the fan have no direction, just go up at random, but pay attention to the positive and negative sides of the fan, and make the side without trunking face outward, otherwise the wind direction will change.

So far, the installation of the overclocking three U-4D dragon reducing CPU radiator has been completed. Before getting on board, take another picture of the removed JL-120 water cooling and the installed U-4D. After this JL-120 water-cooled machine was dismantled, I cleaned it for more than an hour before I cleaned the dust embedded in the water-cooled cooling grid. I was exhausted.

Installation test

When disassembling the machine, because the dust inside the case was too thick, I spent a whole afternoon cleaning up the dust on the removed parts. Especially in the power supply, the dust was so terrible that I just gritted my teeth and bought a new power supply (Patriot 700) on JD. The next day, after the arrival of the power supply, I threw away the old Hangjia 350W power supply. It seems that we need to work hard to keep the computer in good condition! When the new modular power supply is installed, the space in the chassis is much fresher, and a lot of air flow space is made for the U-4D Dragon CPU radiator.

After installation, the device did not light up once. This is an old problem with my 2010 Onda motherboard. According to past experience, I first unplug one memory and try to start the device with a single memory. The computer successfully enters WIN10. Then I shut down the computer, plug in another memory, and restart it. The computer returns to normal. The second time I started up, I entered the BIOS and adjusted some parameters. By the way, I looked at the CPU temperature and the fan speed. The CPU startup temperature was 33 ℃, and the speed of this newly installed radiator was 2008 RPM, which seems to be a little high.

After entering the system, I downloaded Master Lu. Look at the computer information scanned by Master Lu. My computer configuration is old enough, and the graphics card is still onboard. However, this configuration is still very smooth when running WIN10 64 bit, but it is just not able to play large 3D games. It is appropriate to play the quasi guaranteed flower screen. Want to eat chicken? Stew one in the pot yourself!

Turn on the computer and enter the system, browse the web page for a while, chase several episodes of Japanese drama, open Master Lu to watch the temperature monitoring, the CPU temperature is 33 ℃, the fan speed is 2057 RPM, no problem, Laotie.

Seeing that everyone is using Master Lu's temperature and pressure test to test the heat dissipation performance of the CPU radiator, I also came to play and join in the fun. After opening the temperature and pressure test, less than 5 minutes later, the CPU temperature soared to 40 ℃. It seemed that the temperature rose very fast. Then I let the computer continue to burn itself.

After watching TV for 20 minutes, I came back to watch the temperature displayed by Master Lu. At this time, the temperature and pressure test continued. I found that the CPU temperature seems to have stabilized at about 43 ℃, and the fan speed has also risen to 2083 RPM. At this time, the temperature of the hard disk and the motherboard also rose. I thought that this computer could not be used to do such a big thing anyway, so I ended the temperature and pressure test. As for the power played by this overclocking three U-4D dragon subduing CPU radiator, I would like to quote a swimmer's words: I am very satisfied!

summary

It's time to summarize again. As an old user of overclock III, I would like to say that the water cooling of my own overclock III is better than the air cooling of this trial, because the CPU temperature monitored by my Julang 120 water cooling is rarely higher than 30 ℃, while the U-4D Dragon CPU radiator is more than 30 ℃ when it is turned on. However, the noise of this U-4D is much less than that of my Julang 120 water-cooling device. Anyway, the temperature of more than 30 degrees is normal. In addition, the U-4D design is very lightweight, which will not take up too much space in the chassis or cause too much lateral pressure on the motherboard. Therefore, I think this overclocking three U-4D dragon reducing CPU radiator can meet the daily needs of ordinary computer users, Of course, if you are a super player in a large 3D game, I suggest you buy a high-end water-cooled radiator with an overclock III.
