The 921's are a bit of a clunker: Their best efficiency is very close to the same as an 841 and they are not as tweakable as previous Avalon's (like the A821/841) are. The other gotcha is that they use a bigger fan than any other miner uses - it is 140mm - and those are not always easy to find.

I owned 1 Avalon 941

the Avalon is long dead
the innosilicon t2 is mining as I type I had it since spring of 2019

A good place to start for reviews and settings on the 921 is around here (https://bitcointalk.org/index.php?topic=5085231.msg48770866#msg48770866)

wow so my old memory does suck.

got it in dec 2019 not spring 2019

it was a a921 not a a941

but it did suck and burn up the psu melting all the sockets.

could not clock it freely did not like it and it did not last 2 years.

can’t recommend it over the T2 which still works and is easy to clock.
