Well damn it! I was hoping there would be only two intake fans so that I could add two exhaust fans to make it a bit more quiet. But at least I will be able to add two exhaust fans on the PSU. I'm told the PSU fans are the loudest ones with a whinny high pitch noise.
Actually there are plenty of pictures at the Bitmain shop, but yeah, 4 BIG LOUD fans, and 3 little irritating noise makers on the psu, and TWO power cables required, not one.
Its a beast of concentrated power. I'm not sure of the wisdom of that, you could get the same efficiency split in two separate units of half hashrate each, and get better heat dissipation... But i guess that the latest trend with the newer miners.
