If they are using good thermal adhesive and a good fan, it ain't impossible after all.
Avalon 6 comes with a one fan and at least my temps are at reasonable level.
yes it is tru the avalon 6 has 1 fan but it has huge massive heatsinks. It also pulls 1000 watts or less at the ac plug.
the s-7 has 140+ heat sinks and it pulls 1400 watts or more at the wall.
Like I said in my case I have lots of fans so it is an easy fix.
But the price drop of 7 dollars is insulting.
It should of went to 560 not 575
sidehack has a good point if your mining room is 70 f or less you may be good but if you have a 90f or more room you will suffer.
Comes down to drop the freq from 700 to 600 maybe 500 or add a fan
