The best solution for down pressure radiator and DC cooling fan.Cooling Fan Vendor

　　Nowadays, we often use computers in our daily life, and computers are a very important part of us. The DC cooling fan is an integral part of the computer host, which can effectively dissipate the heat generated by the computer during operation. So how should a down-pressure radiator match a DC cooling fan?

　　It has been a while since the last time I discussed where the chassis fan should be installed, and the smell master finally freed up his hand for the next experiment. This time, we will replace the previous tower radiator with a push-down radiator, and study how different CPU cooling methods match the number and position of the chassis fans.

　　This test still uses the previous configuration. Due to the use of a push-down radiator, I will adjust the CPU heat through the bios to maximize the experimental effect.

　　After several experiments, I finally set the multiplier of the Core i7-7700K to 40. After all, the performance of the aluminum bottom pressure radiator is incomparable with the heat pipe tower radiator. During the test, AIDA64's FPU single-bake mode and FurMark's 1080P baker mode were turned on at the same time, and the test time was 20 minutes.

　　In addition, since we have come to the conclusion that "the case fan is best installed in the back position" in the last test, we saved a lot of effort this time. Test directly from the best three positions, these three positions are the middle of the 360mm fan position on the front panel (which can bring low-temperature air to the graphics card and CPU), and the 240mm top plate corresponds to the position above the CPU radiator (pull away through the CPU). and graphics card to heat up the rising air), as well as the best 120mm fan bit on the back. The chassis adopts Huntkey GX600P tower chassis.

　　Due to the different air ducts formed by the down-pressure radiator and the tower radiator, the down-pressure radiator absorbs air from the top of the radiator and then blows it out 360° around, taking away the heat on the fins, which will affect the components and hardware around the CPU. have a greater impact. Some netizens mentioned that the push-down radiator is beneficial to the heat dissipation of the power supply module and the memory. This statement is not entirely true. When the heat emitted by the CPU is small, the temperature of the air blown from the radiator is low, which is beneficial to the heat dissipation of the surrounding components, but when the temperature of the CPU is high, the hot air will affect other components.

　　Unfortunately, the Core i7-7700K has already experienced individual core throttling within 4 and a half minutes of the test. Of course, this is also expected by the smell master. Here we mainly show you when the frequency reduction will occur when there is no chassis fan. It can be seen that the current temperature and maximum temperature of the CPU top cover are both 89°C, which also means that the CPU is still heating up, and the other 3 cores have actually exceeded the 100°C frequency reduction line, and then returned to 98 and 99°C. The graphics card's current temperature and maximum temperature have reached 75 ℃.
