Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if affected while spinning, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Cncmd.exe miner can easily lead to graphic processing unit failure3. GPUs are also tend to have fast wearing when utilized for crypto mining. It is likely an unwanted situation when your GPU’s performance decreases on 20-30% just after several weeks of being used in such a way.
