Again, I wouldn't change that 70 on the temp... the fans shouldn't be a problem and it appears the undervolt will be coming out soon
Good information from Canaan - thank you for contacting them (just gave you one of my few merit points I have to give

). I just changed the temp target to 80 - the fan seems to be still tolerable and keeping the steady chip temp at 70 with this setting.
I agree that when they have a working undervolt that could be a better options.
