Jiuzhou Fengshen Xuan Dagger Shooter Version

Very good-looking design. Second, open several high-definition devices to test the temperature of the CPU at 100% utilization. The maximum temperature is 47 degrees. Generally, the CPU temperature is around 30, and the heat dissipation effect is very good. Third, the price performance ratio is on the right track

In case of AMD, the fastener installation is laborious. In addition, the noise does not sound like the nominal 21 decibels, which is not ideal

A very good fan, much better than the original one

The exterior design is commendable. When the fan is working, it can form a circular air duct with the CPU as the center point, which can effectively heat the CPU while taking into account the heat dissipation of memory, power supply and other equipment.

I ordered it online on the 8th, 29 yuan Nanjing package mail. It's a 12cm fan with 55.5 air volume. It should be said that the positive energy of heat dissipation is good, but in actual use, I found that the efficiency is not necessarily faster than that of the small fan I installed four years ago. I used AMD5000+, equipped with the original fan. The starting temperature is about 43 degrees. When I use the Hunter version of Xuan Blade, the starting temperature reaches 48 degrees. When I open several pages, the efficiency reaches 50 degrees. I haven't played games yet. After comparison, I found that there were two problems with the heat dissipation base of the Hunter version of Xuanren: 1. The base was circular and could not hold the CPU. After it was installed, the four corners of the CPU were exposed. At this time, the CPU surface was completely coated with silicone grease. The test of the CPU surface could only be carried out directly by the wind from the fan, which was covered with a layer of silicone grease, which definitely affected the heat dissipation. Silicone grease is used to closely connect the CPU and the radiator base. Now the base can't be covered. Instead, silicone grease becomes a burden. It's hard to wipe it off. 2. Under the cooling fan, a concave shape can be designed to increase the cooling area. The base is cast aluminum, and a concave surface can be designed, which will not affect the strength of the base. If the improvement is reasonable, this fan should be a good entry-level CPU cooling fan with low noise, high efficiency and high price.

The round shape of the improved base is square, which is suitable for the surface of the CPU. Increase the heat dissipation area of the base to improve the heat dissipation efficiency.

The design is very similar. The fan is big enough to hold the X2250 to watch videos and open web pages. The temperature is 37 degrees! It's really quiet!

This product can't even hold the X3450. The X3450 is on standby for 47 degrees. Once you open the web page, NM can reach 58 degrees. After playing 3D games for 10 minutes, you can directly get 70 degrees on the CPU! The speed has always been at the highest 1600 rpm and can't be increased. It's not as good as my original fan. The original fan can change speed by about 2200+and play 3D games by about 60 degrees! It's just that the full load noise is too loud, and the no-load original fan is just now! Also, the area of the points below the CPU is too small, and the contact surface is only a round one, which can only contact about CPU2/3! I don't like this!

I really don't want to buy a new fan after a long time. The original fan of the X3450 is very easy to use. The sound of the video on the website is acceptable! When I bought the U, JS said that the original fan could not hold the X3 U, I have used it for two years, but it is still the same!
