I've got an ibuypower computer with two Nvidia EVGA 1080TI's in it running nicehash when the computer isn't in use. One of the GPU's is at 84*C and the other stays at 75*C. Any idea why there is such a difference between them, and how can I set the temperature limits for the cards?  What is the max safe temp for these cards? Unfortunately the computer is 400 miles away and I can't remotely access it to make any changes until Friday. So hopefully I'm not nuking one of my brand new cards.

thank you for your help
