In recent years, due to the higher power consumption of the CPU generation after generation, downward pressure air cooling heat dissipation has been rare, only some pursuit of the ultimate ITX small chassis can still be seen in the use of downward pressure air cooling, also due to changes in the market, the new products of radiator manufacturers in the past two years are mainly based on high-performance integrated water cooling and a variety of tower air cooling, and it is rare to see high-performance downward pressure air cooling.
Until recently, this downward pressure air cooling product from Nine Sharks was discovered, which can be said to be a new form of downward pressure air cooling, which increases the heat dissipation area horizontally and is equipped with parallel dual fans to improve heat dissipation performance. When I first saw this push-down heat dissipation, my first reaction was that the mini ITX host could finally be stuffed into a more powerful CPU, but after testing, I found that it was a bit difficult to stuff into the ITX case, but this design did have unexpected effects.
The first time I bought the radiator product of the nine sharks, the radiator is packaged in a color box, and the appearance of the radiator is printed on both sides of the outer packaging, the nine shark JF13K mini provides two colors of black and white, and the black version is optional, and I started here with a white ARGB model.
On the side of the package, the detailed specifications of the radiator, 6 heat pipe design, dual 10cm cooling fans, full platform buckle support, maximum depyretic power consumption of 260W, etc. ·
When the package is opened, the upper layer is a separate buckle bag, and the lower layer is the radiator body wrapped in a pearl cotton liner box.
List of accessories, in addition to the radiator body and cooling fan, with Intel, AMD full-platform metal buckles, standard with a heat dissipation silicone grease, Nine Shark JF13K mini This buckle is very good in a small package, it looks very regular.
Let's take a look at the main body of the radiator first, two 10cm cooling fans side by side at the top, with a conventional thickness, the outer size of the entire radiator is 204mm long * 123mm wide * 101mm high, and it can be seen from the height that this push-down heat dissipation is not designed for small ITX installations, but is more focused on performance.
The heatsink fins have a multi-stage layered avoidance design to avoid conflicts with the motherboard's thermal armor and memory. In terms of specific compatibility, the height of the side of the motherboard's IO bezel on the left side of the heat dissipation is 50mm, which can avoid the height of most motherboards' IO thermal armor. The height of the right memory bit is 59mm, which is basically compatible with vest strips on the market.
The main body of the radiator adopts 51 layers of large-area heat dissipation fins, full reflow soldering process, compared with the traditional FIN process, the thermal conductivity efficiency is higher, the stability of the heat dissipation fin is also better, of course, the process cost is higher than that of the FIN process.
The nickel-plated copper heat sink is connected to the fins of the radiator through six 6mm heat pipes.
The pure white heat dissipation body is also sprayed with nano graphene material, which can avoid the risk of long-term oxidation and corrosion of the heat dissipation fins, and can also improve the overall appearance.
The fan is equipped as standard, with dynamic hydraulic bearings, with a maximum speed of 2200 and a maximum air volume of 4754cfm, maximum noise 302dba。
First of all, let's try the motherboard compatibility of the Nine Shark JF13K mini.
First of all, the colorful Z790 Flow ATX large board, the memory and the motherboard heat dissipation vest are perfectly avoided, and the memory here uses a light bar with a relatively high height of the vest, and there is still a certain distance between it and heat dissipation.
ITX motherboards don't actually need to be tested, the length of the heatsink is more than 20cm, and ITX motherboards are only 17cm*17cm in size, even if the motherboard can be installed, the chassis may not be able to be stuffed in. Here I tried it with the GIGABYTE B760i, and I can see that both the IO side and the memory side are beyond the motherboard.
Therefore, in terms of compatibility, the Nine Shark JF13K Mini is not suitable for ITX installation. Let's directly use the combination of Z790+13600KF to test the heat dissipation performance.
Here we directly use the bare metal open platform for testing, and the specific test platform configuration is shown in the figure above.
The first is daily standby, at room temperature 25, 13600kf temperature 37, memory temperature 36. The design of the Nine Shark JF13K Mini, in addition to improving the CPU heat dissipation performance, can also cover the memory well under the downward pressure air duct and provide active heat dissipation for the memory.
Single-baked FPU with AIDA64, 13600kF (voltage 1.)19V)P core E core average turbo frequency full load,10 minutes laterCPU core temperature is76,CPU power consumption175W,The overall heat dissipation performance is relatively good,Suppressing 13600KF is still no problem,Performance is at the same level as ordinary 240 water cooling,You must know that the price of Nine SharkJF13K Mini is only more than 200,The long-term stability of air cooling and heat dissipation is better than that of water cooling。
Finally, take a look at the lighting effect of the white ARGB Nine Shark JF13K mini, the light effect of the high light transmittance fan blade is still very good, and the effect of installing it into the chassis is definitely better.
The design of Jiusha's dual fan downward pressure heat dissipation is still very innovative,The overall height of 101mm will have good compatibility for some ultra-thin cases,The dual fan design is definitely the ceiling of downward pressure heat dissipation in terms of performance,It can suppress the 13600K level CPU,There is also a large heat dissipation area that can cover the memory bit,It can also meet the high-frequency memory heat dissipation needs of the DDR5 era。
Unfortunately, this cooling is not designed for ITX installations, and it cannot be used by ITX users who need strong cooling.
