Having a strange issue that I cannot figure out.

I have a mix of S7, S9, and Avalon6 units. All of the S7s at various times lose about 20% performance. This happens across the board to ALL s7s I have regardless of what pool they are running on. I have tested on Kano, antpool, f2pool, etc. All of the S9's as well as the Avalons do not lose speed at all. The issue is limited to only the S7, which I have a mix of batch 1 through batch 17 and all of them do the same thing. I have different machines with different firmware so it seems firmware independant as well. Any input would be appreciated.
