R7000 is a router with high cost performance. Currently, Jingdong sells for 799 yuan.
NETGEAR R7000 AC1900M dual-band gigabit wireless router 799 yuan good stability, 200 square meters of residential coverage is good. Jingdong direct link to Wikipedia The culprit point of the NETGEAR router is that the original firmware responds slowly and cannot install plug-ins. Since Koolshare's big gods have developed Merlin firmware, the playability becomes very high. For example, the software center can scientifically use the Internet to advertise. , AppleDNS acceleration, office and operating system activation and so on.
Of course, this router inside Broadcom processor's "temper" is not small, when the summer reached 85 degrees once, during the past has been added to the notebook under the router cooling base, but unfortunately the effect is generally like, can only drop a few degrees only, The decision to transform into active cooling, while also ensuring the aesthetic appearance of the router, has been explored for many times and is now showing the finished product to everyone. Through the transformation, the temperature can be maintained between 40 and 45 degrees (at room temperature 20 degrees).
Note: The items required for the renovation are all purchased from Ma's grandfather's home, and the expenses do not include postage, then 5 yuan (fan 3 yuan, heat sink 2 yuan).
The first step: disassemble the machine, the steps are no longer described, online search. The transformation needs to be done as follows: 1. As shown in the figure, remove the two passive heat sinks attached to the bottom shell. 2. Add a turbo fan, and at the same time refer to the fixing hole of the fan to make a hole in the corresponding position of the bottom shell, and fix the fan with a screw (one of the holes can perfectly use the built-in cooling hole). Note that the fan should not be too thick. If it is larger than the distance between the main board and the bottom case, then the fan's thickness is probably a bit thicker than the diameter of a cigarette (see figure). Of course, if you want to be lazy, or do not want to break the bottom shell, you can use 502 glue or 704 silica gel to fix the fan at the bottom shell. Note: The fixed position of the fan needs to be adjusted according to the size of the fan. What needs to be done is that the fan is kept facing the heat sink. The position of the heat sink is shown below.
The second step: paste the heat sink in the CPU, paste the location can refer to the location of the CPU in my disassemble picture, ensure the heat sink above the CPU, note: the bottom of the shield, the top of the chip silicone heat sink is the router comes with, everyone Do not need to open the shield, I just open to let everyone look at the location of the router CPU, ROM and RAM.
The third step: to take power for the fan, to tell the truth, the quality of the online 3 yuan to buy Xie Xi fan is really beyond expectations, fans can be easily removed to facilitate the late cleaning, while the wind pressure and sound are good. I took the power at the rear USB to take 5V. This step requires electric iron. If the iron is not to be used, external power can be used to find a USB data cable, leaving the USB interface plugged in outside the router. The other side is connected to the fan. At the same time, I took 12V at the power supply (it turns out that the 12V power can not be taken) because after comparing my experiments, 5V is a guarantee of heat dissipation, while taking into account the noise (almost inaudible). 12V cooling is indeed more violent, but it is also noisy. Note: I don't personally use the rear USB, so if you take the power here, it may cause the USB device's power supply to be insufficient.
Step 4: Install the motherboard and install the shell. The process is not repeated. The steps to disassemble the machine will be reversed. Merlin firmware also has a handy convenience is the frequency of ultra-CPU and memory, as shown in the figure, the processor I overclocked to 1.2GHZ use, temperature boot for 1 week, also 44 degrees, compared with more than 80 degrees before It's a heaven and earth. When the voice is heard, it can be heard by the ear close to the router. Even in the dead of night, there is no sound at a distance of 1 meter.
Above, the transformation was completed, basically did not damage the appearance of the router, than I saw other people before the thermal transformation, that is still very successful, the cost is not high, the turbine fan can be used to disassemble the laptop, heat sink size Also free, as long as it is not too thick can be, it is not enough, without heat sink, the fan directly blowing against the shield can also be, the temperature may be higher, but also much better than the passive cooling. Inadequacies, please also correct me
