What should we pay attention to when choosing a CPU radiator cooling water pump?

With the development of e-sports and computer technology, players have higher and higher requirements for hardware, but high-end hardware brings players a high-quality game screen while bringing huge heat. If the heat is not dissipated in time, it will lead to a crash at light level, and may burn the CPU in severe cases. The CPU heat sink is used to dissipate heat for the CPU. Many players use a split liquid cooling solution to solve the heat dissipation problem of the hardware. The split liquid cooling means that the cooling system is formed by connecting the water pipe with the water pump and the cold row. The core component of the liquid cooling block is the water pump, which is comparable to the human heart, and its importance is self-evident.
However, there are many types of cooling water pumps commonly used in computer CPU radiators. What should we pay attention to when selecting models? This article focuses on the basic parameters and points of attention of the more commonly used 400LPH small computer cooling water pump.

The main basis for the selection of PC cooling water pumps
The purpose of installing the cooling water pump is to better dissipate the heat of the whole machine, so that the hardware inside the chassis is in a cool working environment, so that the core hardware can give full play to its performance, and can effectively prolong the service life of the core hardware. This special purpose of use determines the special requirements for the selection of the pump. When choosing a computer cooling water pump, the main consideration is the lifespan, size, noise value and stability of the pump.

1. Lifespan
Life refers to the total time the pump can work continuously. For cooling water pumps, at least 20,000 hours of lifespan are required. Because the water pump is an electronic product, there will always be an aging phenomenon. If the wear and tear is too fast and the life cycle is too short, it will increase the daily maintenance cost, which is very inconvenient for players and increases the cost. Therefore, it is recommended to pay attention to this parameter first when selecting a cooling pump. The TOPSFLO pump structure is specially designed, the magnetic drive rotor and impeller rotate on a ceramic bearing, which prolongs the life of the pump, making it higher than the industry standard, and adopts the high-efficiency ECM brushless DC motor, the actual service life is more than 30,000 hours.

2. Size
The size of the crate is too small to determine the type of water pump used. For example, MATX or ITX computer case, it is difficult to support the use of large water pumps. In addition, the space-occupying components such as the drain water tank, so there is little space left for the water pump. Therefore, before choosing a water pump, the first task is to check whether there is enough space in the crate! It is recommended to use TOPSFLO TDC small water pump, the size is only 30*62*86CM, the shape of the cuboid, it looks very mini, and the installation is really convenient. Its matching straight-in and straight-out barb type joints are easy to install and beautiful in appearance. For larger water cooling systems, you can also consider dual TDC pumps in series or parallel.

3. Noise value
Operating quietness is an important indicator that water cooling must consider. Generally, the noisy workshop is 90dB, the subway car is 80dB, the ordinary conversation is 60dB, and the urban late night and library are 40dB. The noise of the CPU heat sink cooling water pump with better noise control should be within 40dB. At this value, the sound of the water pump can hardly be heard half a meter away from the computer. The TOPSFLO water pump adopts the precise combination of high-precision shaft sleeve and ceramic shaft, which has good wear resistance and realizes quiet and smooth operation. The noise value is as low as 26dB, providing customers with a comfortable experience.

4. Stability
The stability of the water pump determines whether the water cooling system can operate normally. If the water pump fails during use, the temperature in the chassis will rise rapidly, and even lead to problems such as unstable memory and equipment freezes. The stability of the water pump has a lot to do with the electronic accessories selected. From the current situation, the batch consistency of electronic components of international brands is still better than that of small brands or domestic accessories. For example, TOPSFLO TDC pump adopts ATMEL chip, Samsung, TDK, Melexis and other brands’ electronic components, which not only has high efficiency, low power consumption, stronger anti-interference ability, and smoother operation. At the same time, TOPSFLO TDC pump adopts advanced magnetic drive technology for static sealing, and there will be no leakage in long-term use.
In addition, when choosing a computer cooling water pump, its ease of use should also be considered. TOPSFLO TDC pumps can be plug-and-play and can be directly connected to any computer power supply through a standard power connector to quickly solve customer needs.

There are many factors that affect the quality of pumps, such as raw material channels, R&D and design capabilities, manufacturing processes, quality control, etc., and when we choose the right supplier, it means that we are not far from choosing a good product. As the first domestic company to enter the field of micro-pumps, TOPSFLO has been focusing on the R&D, manufacturing and export of high-end brushless DC pumps for nearly 20 years, and has been occupying the leading position in the export of micro brushless DC pumps in the world. TOPSFLO is committed to helping customers in various industries solve their actual needs and pain points, and provides customized product solutions. At present, there are more than 10 million TOPSFLO micro-pumps running stably in more than 60 countries and regions around the world!
