B866S2 Thermal Modification Comparison and Experience

To check the temperature, you need to open telnet, I am a R23S200 system Unicom original, log in with ultra-secret, and open telnet on the "security" page. If the interface is gray, you can press f12 to open the foreground to remove the disable of the checkbox, this is a bug, if it is fixed to the background inspection, this trick will not work.

1. The heat dissipation of the device is from the front, and there should be no thermal conductive material in the back shield cover to transfer heat to the back shield cover, so there is no need to remove the veneer screws.

2. FPGA has the highest temperature Aluminum sheet for heat dissipation is pasted, in fact, FPGA is more resistant to high temperatures, so the original factory does not design heat dissipation.

3. The second is the mask, note that the laser is afraid of silicone oil penetration, the thermal pad will penetrate the silicone oil after a year or two, and the low temperature of the laser can greatly extend the life.

4. The black radiator on the front is pasted with a vapor chamber, and then a cooling pad is added to the top cover. Pay attention to the compression amount of the thermal pad should not be too large to avoid excessive stress on the board and reduce the life of the solder joint.

5. I use carbon fiber thermal conductive film and carbon fiber thermal pad, the thermal conductivity of 35w is a good material but conductive, use this material to pay attention to the debris short circuit.

6. Both the WiFi and the SOC are depressed by 10°, in fact, I am more concerned about the WiFi temperature affecting the throughput performance, the WiFi chip and CPU are under the black heatsink. The wifi temperature is closest to the threshold with the least margin.

Black heatsink plus material top cover large cover sheet SoC and WiFi chip temperature.

Add another radiator to the case

It's easy to go directly to the temperature control fan

The fan has more or less noise, which is unbearable in the dead of night, and accelerates the aging of power supply devices.

The appearance is not good-looking

It doesn't matter if he doesn't use it for a lifetime, he will change it when it is broken

Picture a toss for fun.
In fact, the more you toss, the faster it will break.
We must believe in the design quality of Huawei's major manufacturers.

My weak current box is behind the sofa, and I keep the light cat inside, which is not breathable at all, and it is used well. I used to throw a sub-light cat in it, and it was very hot. It's been almost 1 or 2 years for the light cat, and if it's broken, just find an operator to replace it.

I bought this one for 230 oceans, so I take care of it。
Figure a 2.5G port and 2x2 full-blooded wifi7, the latency of a device with router and optical modem will be less! Otherwise, it will affect my lol and cs scores! One step ahead of others

I bought it back as a 200 system, Unicom original 24.10 machine
