I just wanted to say I really like Avalon machines. Honestly compared to bitmain, Canaan make the better machine from someone that works on these machines.  I really like how each chip has its own temp sensor, Also to remove a fan you dont have to pop the top off which is super nice.
here is the avalon 1246 96T, check it out: https://shop.canaan.io/products/canaan-avalon-miner-a1246-96t?VariantsId=10001
