This is good advice,   Though all three of my blades are exhibiting the exact same behavior so I don't know how to play them off against each other.  I did however try to move the strongest PSU around them and it made no difference.  I'm convinced the blades themselves have a reset timer built in.  As if a condition exists that is causing them to re-start in an attempt to mine.

I am fairly certain it is not a heat issue, I have the three blades mounted about 2" apart vertically and I have a extremely strong blower blowing between/around and through all three.   It is thousands of CFM.  It is the style you would see at a store to dry off the floor after a long rain.  I have to run it on the lowest setting otherwise I risk blowing the blades across the room!     When I reach into the gale force winds, the blades are warm only.   on all surfaces.

My 'gut' is telling me there is a connection issue causing my blades not to recieve proof of work/submission etc from the pool and they are auto-restarting.   I am going to try to get into my router and make sure I open all ports (if they are not) and see what gives.  I have a feeling these blades think they need to restart because they think they are hashing without reward?    Are they smart enough to check for that and restart?!
