When it comes to cost-effective liquid cooling radiators, PC DIY users will definitely think of the brand Yajun. In recent years, Yajun has gained a firm foothold in the highly competitive water cooling radiator market with its affordable EA and GA series products, and has brought consumers a series of sweet and fully functional water cooling radiators.
Recently, the design of water cooling radiators with cold heads and multi-function screens has become popular, so in order to ensure that its products do not lag behind the market wave in terms of functionality, Yajun launched a 360 water cooling radiator product with a cold head with a screen today (December 22, 2023) - Yajun BASIC5 Pro. Surprisingly, Yajun's 360 water cooling radiator with a multi-function screen is only priced at 399 yuan, which is the first 360 water cooling radiator with a screen within 500 yuan.
Preview'); table().init();The Yajun Basic5 Pro we received this time uses a white box, so the product packaging cannot be displayed here. After taking out the radiator body, I found that the product has been pre-installed with a fan for the user, and it can be installed on the machine immediately after hand, and it can surprise people in terms of texture. The product adopts an all-black design, although there are no design elements on the fan and radiator, but the visual perception of the product will be very textured under the all-black background, and the screws and cold head fixing brackets used to fix the fan are silver, which will have a certain visual contrast with the all-black design of the product, and also break the visual boredom.
In terms of accessories, the preview includes the Intel LGA 1700 mounting base (metal), AMD mainstream platform mounting bracket (metal), several screws to fix the radiator, and a small tube of W17 heat dissipation grease produced by Yajun.
The size of the Yajun BASIC5 PRO cold head is smaller, and the specific data is 67 67 47mm. In terms of appearance design, the cold head part of the product has more design language, and the overall structure of the top of the cold head is the outer ring + RGB light strip + screen. The outer ring adopts a special-shaped design, which is a circle with a notch, and the outer ring has a certain space from the screen, which is equipped with an RGB light strip, and Yajun uses a black rubber ring with a scale design to fix it, and the middle screen part also has a "bulb-shaped" RGB light strip to wrap the screen.
On the whole, the cold head of Yajun BASIC5 Pro has a strong three-dimensional sense of vision, and the styling design with RGB lighting effects makes it look very similar to a reactor. Although the pleasing appearance of the product depends on the user's personal aesthetic style, the cold head design language of Yajun BASIC5 Pro is richer, and it can be seen that the brand has also put a lot of thought into the appearance design.
In terms of performance, the maximum speed of the pump is 2400 10%rpm and the operating life is 30000h. At the same time, in order to facilitate the user's installation, Yajun BASIC5 Pro has been pre-coated with heat dissipation silicone grease for the user on the copper bottom, which is convenient for users to install and use directly.
*In terms of cable management, there are two cables extended by Yajun BASIC5 Pro cold head, which are 9pin USB interface cable and a dedicated 7pin flat head design cable, the end of the special cable has a 4pin pump interface and 3pin RGB interface, it is worth mentioning that the RGB interface end is also designed with a 3-pin RGB adapter, which is convenient for users to access their own RGB expansion cable.
In terms of fans, the Yajun Basic5 Pro comes with three black fans with no RGB lighting. The three fans are connected with a custom 4pin flat head cable, because the cable, radiator, and fan are all made of black color, so the gap between the fans hidden in the series cable will not produce a visual abruptness, so the product looks neat in the radiator fan part. There is also a 4-pin fan connector at the end of the dedicated serial cable, which can be connected to three fans on the CPU fans pins of the motherboard to run normally.
In terms of performance, the official nominal data is a maximum speed of 2000 10% rpm and a maximum wind pressure of 24 10% mmH2O, maximum air volume of 68 10% CFM.
PreviewBecause our cooling test platform is Intel LGA 1700 platform, and the PC on the computer this time is the AMD platform, so I have experienced the installation method of both platforms this time.
First of all, let's talk about the fixed bracket on the cold head, the product is designed with four screws at the bottom of the cold head to fix the brackets on both sides, and you can switch the fixed brackets of Intel and AMD platforms after unscrewing the screws.
The process of installing the Intel LGA 1700 platform is not easy, the product directly inlays the fixing screws into the cold head fixing bracket, and the fastener base is pre-pasted with 3M glue to help users fix it on the back of the motherboard, but the fastener base will loosen and slip off if you push a little harder during the screwing process, so it is recommended that the user hold the base with your hand, and then align the screw holes in turn and screw them into the fastener base.
As for the installation process of the AMD platform, the installation process is relatively easy, because the AMD base can be screwed on top of the motherboard and will not slip off, so users only need to put the two holes under the cold head fixing bracket into the base and tighten the screws.
The cable management process of Yajun BASIC5 Pro is quite easy, after all, the fan cable of the product has been connected in series, and the pump interface and RGB interface cable on the cold head are also equipped with a special one-point cable, so you only need to hide three cables to achieve a beautiful and concise visual effect after getting on the machine.
The control software of Yajun Basic5 Pro is "PA", and the software section is divided into four parts, namely homepage, theme editing, settings and about.
In the "Home" interface, users can select a preset theme here, and there are a total of 8 themes officially prepared for Yajun Basic5 Pro users. Users can directly click on the theme** in the interface or the text box below to display the effect, and the screen is more responsive.
In the "Theme Editing" interface, users are allowed to customize the display content, the display effect of the current screen is displayed at the top of the interface, and the two directional icons below can be clicked to rotate the screen display content.
In the "Theme Editing - System Information" column, users can click the "t" sign next to the value to adjust the font type and size, and click the color block module next to it to adjust the text color. The left and right parts of the same module correspond to the upper and lower lines of text.
Previews in the "Theme Editing - Background Display" area allow users to upload or display background content.
Click on the "img" software to allow the user to select the jpg format file to upload, after uploading the software will be generated into a preview style, the user can adjust the zoom below the preview area, and drag the screen directly with the mouse to select**display area.
The first icon on the right side of the preview area provides the vertical centering function, after clicking, the scaling ratio will be restored to 100%, and the position will become vertically centered, and below the icon is the horizontal centering function, after clicking, the effect is the same as the vertical centering function, but **will become vertically centered. Below the vertically centered function key is the **Rotate button, which can be rotated**90° with each click, and the application button at the bottom can be clicked to take effect.
Preview click "gif" software allows users to select their own GIF format file to upload, after uploading the software will be generated into a preview style, effective immediately after uploading, and there is no custom function of the above **.
There is also a hidden area in the preview "Theme Editing", click the arrow button on the far right of the interface, the software will pop up multiple hardware information, after selection, the screen can enter the carousel mode, and the screen will switch the selected hardware information every two seconds.
In the "Settings" interface, users can choose whether the software will start automatically at boot, the temperature unit form, and the display angle of the boot animation, and there is an update reminder at the bottom.
At the bottom, the "About" interface displays Yajun's logo, **, and the version number of the software.
In summary, Yajun basic5 ProAlthough the screen cannot be set*** and the degree of theme customization is not high,Only support to change the background** and text style,There are no other pattern icons for users to DIY theme,But the screen responds faster to the software,And PA software is not difficult to get started because of its relatively simple functions,Combined with the price, I think the screen software experience of this product can be regarded as an excellent level。
The test platform uses Intel Core i9-12900K and MSI B760 platform to conduct thermal testing, in which the CPU power is set to 260W, the room temperature is about 22, and the temperature rise of the CPU is recorded by the test data obtained by copying the CPU for 15 minutes (CPU temperature - room temperature).
PreviewIn order to make a better unified comparison, we also convert the heat dissipation performance index of the heat sink into the super energy index (EXP), which is actually a simple conversion of the heat sink thermal resistance, the larger the EXP, the better the heat dissipation performance of the heat sink. Under each power consumption, the thermal resistance value of the radiator under the same conditions is basically the same, so this super energy index is also a fixed value, and it can be approximated that every 1 point higher in the super energy index will have a good cooling effect on the 300W CPU1.
PreviewIn the heat dissipation performance test, the CPU temperature rise of the test platform is only 59 under the effect of Yajun BASIC5 Pro3. The Conversion Super Energy Index (EXP) score is as high as 822 points, such a strong heat dissipation performance is considered an excellent level even in the entire water cooling radiator market, which can meet the needs of most users.
In this test, the data is based on the air volume and air pressure test device made by the super energy network, which is prepared according to the relevant national standards and ISO standards, and measures the air volume and air pressure of the fan through the multi-nozzle orifice plate of the pipeline test air chamber, and the air volume under different system impedances (ordinary radiator, ordinary tower radiator), and monitors the real-time speed of the fan through the speed tester.
Preview'); table().init();The official nominal value of the Yajun Basic5 Pro fan is a maximum speed of 2000 10% rpm and a maximum wind pressure of 24 10% mmH2O, maximum air volume 68 10% CFM. In the actual measurement, the maximum speed of the fan is 2131rpm, and the maximum static pressure is 291mmH2O, the maximum air volume is 78cfm, and the fan speed, air pressure and air volume values are better than the official nominal values. If you are still vague about the air volume, air pressure, and system impedance, you can refer to our popular science article "Really Understanding the Air Volume and Air Pressure of Cooling Fans". Here is the test of the pressure of the heatsink on the CPU surface, too low pressure will affect the contact between the heatsink and the CPU surface, long-term excessive pressure may cause the motherboard to deform, generally speaking, the thermal resistance of the silicone grease between the heatsink and the CPU surface will slowly decrease with the increase of pressure, when the pressure reaches a certain level, the thermal resistance of the silicone grease will tend to stabilize. According to our long-term observation and testing, the pressure of the general air cooling radiator is recommended to be more than 15kg, and the pressure of the water cooling radiator is recommended to be more than 20kg.
We installed the Yajun BASIC5 Pro with the LGA 1700 socket, and the results of the pressure sensor test showed that the installation pressure was 512 kgf can completely minimize the thermal resistance of silicone grease.
The important role of the mounting pressure is that when the heatsink is in contact with the processor, the greater the mounting pressure, the smaller the thermal resistance between the two. In the process of increasing the installation pressure, the greater the installation pressure, the faster the thermal resistance decreases, but after reaching a certain level, the decline rate will slow down until it is in a flat state.
The noise test scene is our specially built anechoic room, the lowest ambient noise is about 15dB(a), the fan is located in the center of the room, and the distance between the noise meter and the center of the fan suction surface is 30cm.
Preview: The single fan of Yajun Basic5 Pro idles at full speed with a radiator connected to the noise level of 458dba, the overall noise level of three fans is 51 when installed to the radiator5dba, the fan runs at full speed under the open platform without obvious hearing, and the noise control is excellent. The noise test can only be used as a reference, and the user's use environment is related to the chassis style.
Before Yajun basic5 pro went on the market, the cheapest 360 water cooling radiator with screen was also sold for about 500 yuan, so combined with the market**Yajun basic5 pro is very competitive in terms of price, in addition, this product can also bring users excellent heat dissipation performance and noise control level, the screen response to the software is also quite fast, no obvious operation delay, and great value for money is definitely the most appropriate adjective for this product.
But after all, there are ** limitations,Yajun Basic5 Pro It is impossible to do everything,The installation experience of this product Intel LGA 1700 platform is average,And the degree of screen customization also has room for optimization,The fan does not have RGB lighting effects。 But if you don't mind the shortcomings mentioned above, Yajun Basic5 Pro can definitely bring you an excellent product experience with a relatively low price**.
