CN8CardSaver for NVIDIA GPUs

CN8CardSaver is a high performance CryptoNight NVIDIA CUDA miner forked from XMRig-nvidia.

cn8cardsaver is a miner for CryptoNight coins with GPU temperature and fan control support. With it you can keep your expensive cards save. Keep it below 65 C to be on the safe side. If it gets to 80 C or above you could be damaging your card. Use the options --max-gpu-temp=65 and --gpu-temp-falloff=9 for example

GPU mining part based on psychocrypt code used in xmr-stak-nvidia.

Temperature control:

Command line options

      --max-gpu-temp=N      Maximum temperature a GPU may reach before its cooled down (default 75)
      --gpu-temp-falloff=N  Amount of temperature to cool off before mining starts again (default 10)
      --gpu-fan-level=N     -1 disabled | 0 automatic (default) | 1..100 Fan speed in percent
