My T3+ 57Th  have finally arrived and I have them fired up to test before they are off to the Host.
So far so good exactly at spec...57th on performance drawing 3300W Fans steady at 70% with chip temps hovering in low 70's.

So
High performance we have 57Th @ 3300W (Insane jet engine loud when warm)
Reduced settings
Factory setting puts out 50Th @ 2550W Ambient is 65F (Not for long) fans @50%..... chips temps high 60's
Balanced........not checked yet
Economy.....39Th @ 1800W !!!! And Not too loud at all...tolerable

These are early results after only a few hours on each.
Definitely will NOT be running them full tilt.
All this on stock firmware
These units are for sale in Ottawa but will soon be in Labrador at Cryptoboreas
