Thank you for the fan fix blissz, couldn't replicate the problem, but had a feeling it had to do with when there's a network interruption, much relieved it's fixed.  Had chips go to 114 degrees on one machine before I noticed and quickly intervened.  Error rate was higher than normal after that on that machine even after restarting, but after a short cooldown period they are working perfectly again, guess I dodged a bullet.

Also received my end Nov batch d3 and the fans on this model is of a poorer quality, different model, lower amp and much louder than the fans on other batches, a shame since my other d3's were all much quieter with the custom firmware and now the new machine just tops out the overall noise level again.
