Xianma KW240DW integrated water cold radiator evaluation: can be DIY cold head pattern full white cost -effective choice
Xianma’s chassis and power supply is a brand familiar to many users. It has always had a high cost -effectiveness and has high sales in the market. With the development of the business, Xian Ma also launched related radiator products. In the past two years, a variety of integrated water cold radiator has been launched, including all white products with RGB light effects. Player.
Earlier, the first horse launched a integrated water and cold radiator named Bingcai 240W (“First Ma Bingcai 240W Integrated Water Cold Reluctors Review: New Selection of Dazzling Dazzling”), the full white color color is very dazzling, specially, especially It is an integrated shining guide tube, which makes the use of RGB light effects to the next level. This time, the first horse brought another integrated water cold radiator named KW240dW. Although there was no glowing guide pipe, the first horse chose to work hard up and down in the water cold head and adopted the design that supports the custom DIY pattern.
Appearance and packaging: full white shape, chic cold head
Xianma KW240DW integrated water cold radiator outer packaging uses a new style, which is matched with white and light gray. The bottom surface of the product rendering is white and the four sides are light gray. Because KW240DW is a pure white product, it shows the RGB light effect characteristics of the radiator. The front and back of the outer packaging are the same. In addition to the radiator picture, there are models and RGB characteristics. The simple introduction and basic parameters of the product are placed at the bottom.
In the internal packaging of the first horse KW240DW integrated water -cold radiator, including cold and water -cooled heads, two 120mm RGB cooling fans, Intel and AMD platform fasteners, various power supply and control wires, each installation required for installation required Species, hub, installation manual and warranty card. In the internal packaging, KW240DW has actually installed the cooling fan, which has reduced the operation steps for many users. This is worthy of praise.
KW240DW’s all -white shape design is relatively concise, the overall is relatively regular, there are no obvious bumpy places, the appearance looks very white and has a good face value. KW240DW uses the cold head of the first horse mirror series, and the top uses a rotatable design. No matter which direction is installed, the direction of the sign can be adjusted as needed. The user can also replace the acrylic lens, even the custom style, and the LED light circle and unlimited mirror RGB aperture to create a different visual sense. The outside of its guide pipe is wrapped in a layer of fine nylon mesh, making the guide pipe more tough and durable.
KW240DW supports Intel’s LGA 775/115X/1366/1200/1700/2011 platform, and AMD’s AM5/AM4/AM2/FM1/FM2/FM3 platform, which basically covers the mainstream platforms on the current market and in the future for a period of time Essence
The two heat dissipation fans with KW240DW are white as a whole, with RGB light effects. It has 9 semi -transparent fan blades, using a hydraulic axis fan, and 8 corners of the four corners to reduce shock -absorbing and shock -absorbing and shocking to reduce noise. According to the official introduction of the first horse, the maximum air volume of this heat dissipation fan is 73.9 CFM, the wind pressure is 1.22 mmH2O, and the noise is 29.5 dB (A). It is a cooling fan that focuses on the air volume.
Installation experience: simple structure, but need skills
The first horse KW240DW is not complicated in installation. The structure is very clear. There is a lot of operating space around the water -cooled head, and the wiring is very simple, but it is difficult to operate. The long screw cap with a spring is not directly fixed on the water -cooled head bracket, but is separated. Unlike the past Bingcai 240W, the KW240DW uses a separate column.
When installing, it is best to twist the column with your hand first. After the four long screw caps are relatively fixed, then tighten it with a screwdriver. In this process, the position of the water -cooled head is easy to deviate, not only to be more careful, but also take some effort.
After lighting, you can see that the unique water -cooled head design of the first horse KW240DW has a different visual effect, and the light color is also more comfortable. With the white appearance, it looks very chic. KW240DW’s water -cooled head and fan all provide a 3PIN 5V interface. It supports RGB light control. Without a controller, you can directly insert the motherboard to control the RGB fan.
Test and explanation
The radiator performance test adopts our customized test platform to better obtain consistency and facilitate comparison of various types of radiator performance. In our test model, test in the limit load (300W, simulates the power consumption of a fever -level player CPU), high load (250W, simulated high -end CPU power consumption) and mid -load (200W, simulate the power consumption of the mid -range CPU power consumption ) The heat dissipation capacity under the lower position only tests the ability under the load in the load, and the higher positioning can test the ability under high load and limit load. Readers can directly measure the temperature of the heat dissipation capacity of the radiator from the temperature of the model under various load platforms (the temperature when the heat resistance has been calculated by calculating the heat resistance to the temperature of the ambient temperature at 25 degrees), the lower the temperature under the load, the heat dissipation under the load The better the performance, and this temperature is similar to the temperature of the CPU under the heat sink, it can be used as a reference for the temperature of the machine.
During the test, the fan of the radiator is running at full speed. According to the need, we sometimes test the performance at low speed for reference.
In order to better compare the unified comparison, we also transform the heat dissipation performance indicators of the radiator into a super energy index (EXP). This is actually a simple conversion of the heat dissolution of the radiator. The better. At all power consumption, the heat resistance value of the same conditions is basically the same, so this superpower index is also a fixed value. It can be approximate that the superpower index is 1 point every height. Good 1 ° C.
Heatheating test: reach expected
In the heat dissipation test, Xianma’s KW240DW integrated water cold radiator played a normal level. It can be seen that in the heat dissipation test, although KW240DW and XPG L240 ARGB will be inferior, the price of the latter is much cheaper than the price (899 yuan). With KW240DW’s heat dissipation performance, it can meet the configuration needs of ordinary users, which is enough for ordinary PCs.
It should be explained here that our super -net test platform has made targeted adjustments on the new generation of Intel’s new generation LGA platform. There is also a certain reference value for users who want to match Intel’s 12th generation Core series processors.
According to the test data, after converting to the super -energy index, the score of the first horse KW240DW is 73, which is a normal level in the air -cooled radiator.
Stress test: Basic compliance
While Intel’s new LGA 1700 socket (Socket V) retains 37.5mm width, the length is increased to 45mm, from square to rectangular, and its Z height will be reduced from 7.3mm to 6.5mm, a decrease of 0.8mm. This requires manufacturers to use new back panels and brackets to meet the installation requirements of the LGA 1700 socket. In order to ensure the good contact between the CPU top cover and the bottom of the radiator, higher installation pressure is required.
According to the official specifications of Intel, the radiator used by the processor of the LGA 1200 socket should reach the 30 kg level, the maximum of 80 kg for power level. If it is a radiator used by the processor of the LGA 1700 socket, the range is between 50 kg and 100 kg.
The first horse KW240DW is installed in the installation method of the LGA 1700 socket. The results of the pressure sensor test show that the installation pressure is 38.8 kg forces, which is slightly lower than the use of the British LGA 1700 platform.
The important role of installation pressure is that when the heat sink is in contact with the processor, the greater the installation pressure, the smaller the thermal resistance between the two. In the process of increasing installation pressure, the greater the installation pressure, the faster the thermal resistance decreases, but after reaching a certain degree, the decrease rate will slow down until the smooth state.
Fan test: slightly different
In this test, the data is derived from the self -made air volume pressure testing device of the ultra -energy network. This test device is prepared in accordance with relevant national standards and ISO standards. And with the air volume under different system impedance (ordinary cold row, ordinary tower radiator), monitor the instant speed of the fan through the speed tester, and measure the fan at full speed and match the ordinary cold row in the special mute cabinet. Noise value.
The maximum speed of the actual measurement of the first horse KW240DW is about 1800 RPM, the maximum static pressure is 1.82 mmH2O, and the maximum air volume is 63 CFM. In the actual measurement, the wind pressure value is higher than the official nominal value, and the air volume is lower than the official nominal value. If you are more vague about air volume, wind pressure, and system impedance, please refer to our popular science article “True Wind and Wind Pressure of Heating Fan”.
Noise test: quieter
The noise testing scene is a closed space of 20 square meters. The environmental noise is below 30 decibels. The fan is located in the center of the room. The distance between the noise instrument and the center of the fans is 25cm.
The noise at full speed is 34.3 DBA, and the noise value after the overall installation to the radiator is 34.7 DBA. The noise test can only be used as a reference, which is related to the user’s use environment and the chassis style.
Summary: The cost -effective choice with playability
The water -cooled head design of the first horse KW240DW integrated water -cooler radiator does bring a different visual effect, and it provides DIY space, which has a certain playability. Compared with the promotional picture, the effect of the real thing is obviously better. The first horse continued the full white design of Bingcai 240W on the KW240DW, maintaining a simple and crystal clear appearance, and the workmanship is more refined. With the continuous efforts of the first -in -one water -cold radiator market, related products seem to become more and more mature.
In terms of heat dissipation, the performance of KW240DW meets its positioning and can meet the purchase requirements of general users. In addition, KW240DW integrated water -cold radiator performs well in terms of noise, which is more suitable for users who are sensitive to sound and like a quiet environment. If you want to build a white theme system and buy an affordable all -white color matching integrated water cold radiator, the first horse KW240DW is still in line with the requirements.
