An update from Canaan regarding hooking A721 with A741.
Hi, yes you can connect A721 and A741 to the same Controller. The firmware can support A7xx in the same chain
Although the voltage setting is different. So it is up to you if you want to run your setup with the devices separate or not. Actually, let us know if you try this and what the results of the setup are for you ok?
As for the cooling numbers, we are working on that but its nearly Chinese New year so there will more than likely be delay on this.
Thanks
Jon
Will post pictures of the A721 with and without the air forming cooler after breakfast as well as screen shots.
