power consumption is currently not a concern
Settings on MSI:
1.3 volts
20% power
1220 core
1070 mem
80% fans
Drop the memory to 150 or 300 since it doesn't effect mining output and it will put out less heat. Drop the core clock from 1220 to 1200 if it's crashing. If it stays stable for a day consider toying with 1210.
80% fan is fine if you're going to only mine for the next 2 weeks, otherwise you're putting more wear resulting in buying a new fan (gonna cost more than you'll make in BTC). Run the fan at 50-60%.
