I used it as a mining machine before, and I posted an article when I bought it https://imglan.com/308.html
Ask me if I have paid back the money. According to the previous and the current high point, I have really paid back, but I reinvested in the altcoins, and I also lost money in my own cash. =
Due to the summer, the temperature of this machine is basically 83+, and the maximum life of the graphics card is below 75 degrees. It seems that the fan must be cleaned and silicone grease must be cleaned. Before Lenovo 60 yuan to pack silicone grease and clean the fan, I was very satisfied. But Raytheon is basically an outsourcing shop. I called and asked, 99 to clean the fan, and 100+ for silicone grease.
Forget it by yourself, although it is still under warranty, but I really don’t like Thor, so I think I can make some extra money for the last silicone grease.
I saw that Lenovo only used silicone grease sheets before, which is much more evenly spread. Taobao bought Honeywell 7950 phase change thermal grease sheets, 31 50 0.2mm, free shipping 20
Note on disassembly:
The removal of the case requires the use of plastic cards to slowly lift up. If you have removed the iPhone and changed the battery, it is very easy.
The screws must be classified. In addition, after dismantling the outer cover, take pictures inside. Because the screws are of different lengths and wrongly installed, there will be important hidden dangers.
Do not use a metal spudger to open the internal cable, but use a plastic spudger. I have replaced it myself because I bought an iPhone battery before, so I still have extra tools to fill it up.
After cleaning the old silicone grease special cloth, similar to the material of glasses cloth, cut the corresponding size of the silicone grease and paste it, not too much nor too small, just cover the chip a little more.

Ignore the clutter and don’t want to take pictures seriously~~~ By the way, I was pleasantly surprised to find that this machine can actually have 2 SSD hard disk interfaces + 1 FDD hard disk interface.
After changing the silicone grease, when the mining is indoors at 30 degrees, the GPU is reduced from 83 to 73-75, which can basically be reduced by 10 degrees, and I am very satisfied.
