if you add the command
-tstop 50
It should stop the miner if your GPU reaches 50C but I think that would be a very low threshold
If you do this the miner will restart immediately (my guess). Any temperature >50 will cause a restart, and any operation in a GPU will cause a temperature >50
What Venum666 wants is a new parameter in claymore which will make miner restart if the temperature drops too low. This does not exist atm.
What exactly is your problem Venum666? What is your scenario? If it is what I think it is, then parameter -minspeed will do the job you want (readme.txt)
