Thanks for confirming. That would place your payment time at 9:55PM in China, where as my order was paid at 12:31AM Chinese time. Maybe that has something to do with it. 

Just sent them an email at webmaster@bitmaintech.com

Best case scenario for me is that they actually manually verify payments and nobody was working at 12:30am over there. 9:55PM is pretty late to be working too, so I'm probably wrong about that. I'd imagine that they must have an automated system to confirm payments.

Guys, I want to buy a 2nd fan to put at the front.
Is it a 120mm?

I really like the Arctic F12, but it doesn't come with a 3 pin fan header to 4 pin molex adapter, so can you recommend a cheap fan that does.

Thank you.

Search for "Arctic f12 pwm"   I have a few of those on my ants connected to 2nd blade pwm.

Yes it is a 120 mm PWM fan.
I use a Coolermaster Blademaster 120 mm PWM fan, but I have to shave away the clip, otherwise it don't fit.
They use special fans where the clips are slight different than aftermarket casefans.

I connect it directly to the fan pin of the Antminer.
It is definitely worth to put another fan onto the Antminer, using a push pull configuration.
Look at the hashrate, it slightly improved without OC.

You have to shave away the the 2 small clips at the fan header, otherwise they don't fit.
They don't use common pin headers.
The Coolermaster Blademaster PWM are cheap and works great, no throttle sound anymore if you put an extra fan in front of it.
The Ants hash slower when they get warm.

Without an extra fan you will hear the fan spins faster from time to time.
Hashrate will be a bit higher due to extra work for the Ant and then hashrate will drop.
If you put an extra fan, the Ant is running smooth and hash better

Do these Antminers come with Wifi built in?  If I go out and get the Wifi antenna, I don't need to get an access point ?

Muchas Gracias Elasticband!!

8.8.8.8 
8.8.4.4

still cant access the rig without the ether cable, despite it hashing via wifi....

wierd but whatevs. lovely & quiet! plenty heat coming off the sinks
;
i dont like the flickering LEDs but it mines, thats what counts,

Bah,  My antminers computer gaming portals seem to be held up at for least a day at US customs. They have not released them yet and I am getting a little nervous.  Anyone else have this happen to them?
