mining does kill GPU's. most vendors will not give any warranty if they suspect its been used for mining. the amount of heat that they pump out is intense and can anneal the copper heatsink to the point where it can warp and discoulour. just like my old one. a good idea is get a can of compressed air and clean out the heatsink on your 1060, it should make it more efficient. if you still have trouble. head on over to our Discord and someone should be able to help you out.
