I got both my v2's back today. Ran about 5 minutes and everything seems to check out just fine. Ran ultra cool. The fan seems to blow stronger, but then again, I have been running mine without a fan for the past month, so I might not remember what it ran like.

They added some padding in the case to help prevent the fan plug from breaking. There also appears to be shim on the fan to keep the blades from catching. I actually can tigten down the zip ties on it real good now and not interfer with the fan blade.

I don't think a fan is needed, but they are good insurance. I ran a 30 minute A main with NO FAN on 4s last weekend.

I am really digging the bullet plugs. They seem more sturdy than soldering to the board.
