Bumped the frequency to 600 overnight and got pretty good temperatures so I bumped it to 625 and while I'm not getting 4.7TH I'm getting anywhere from 4.2 to 4.4TH and temp wise the blades are at 68c, 64c and 60c. Fans are at 40%. Currently have the miner still in my bedroom in the closet which has dampened the noise quite a bit. I was able to sleep with the miner on last night.
