As you can see,S3 have two fans mounted on both front and back ends that mean fans are able to work at lower speed to dissipate all heat easily.

There are two of white Bitmain logo on the both side.

The dimension of the machine:

Size:  255 mm x 136 mm x 158 mm
Weight:5.2kg without package.(5.8kg total)

2.Installation:

S3 is very easy to install.You should just connect the power supply and cables, then it will going to work.
We used 500w psu for test.

First,get 24pin's green line to connect with any black line.

Then,as you can see that there are 4 PCI-e connectors for +12V DC input, but it only needs to connect two of them if without overclocking.

The S3 mines stand alone, needs no proxy server,just connect AntMiner and your PC via Ethernet network cable.
During S3 is working,2 status display lights would flash.

3.Software setting:

Enter  AntMiner’s IP address: 192.168.1.99 into your web browser, then login  Miner
Management interface, both of username and password are ‘root’ by default.

Through ‘Status->Miner Configuration, you will be able to configure your AntMiner.

Pool URL- you should enter the URL of your desired pool.

Worker- this is your worker ID on the selected pool.
Password- this is the password for your selected worker. In general password can be set casually.

After miner worked 18h,the average hashrate is 445G.After 20h,HW value (hardware error) is only 85,almost negligible.

4.Power consumption, noise and temperature test:

Environment:

temperature: 31 degree
humidity: 56%
environmental noise: 41dBA
The on wall power consumption of S3 is 352w.

222420qy3966kzkc9953k9.jpg

The hash boards temperature is about 45degree.The former case temperature is about 37 degrees.

222420rx5bz7lbe3vv9b3z.jpg

From the back,temperature is about 40degree

222420c7nb1knarbviai0a.jpg

Noise, because the room temperature is 31 degree, so the fans always run in high speed mode(speed up to 2400 +). In front of the S3, noise is about 65 dba.

222421p3m4mc33ml61i34i.jpg

On the side,noise is about 67 dba.

5.Internal structure

As same as S1,S3 has 2 hash boards.The customized heat sinks mounted to the hash boards, one box over S3 to control the air flow.

This is S3's controller with network interface, data interface and a small horn.

One of hash boards,with 16 chips(28nm tech process).

The 12cm fans with the logo of AntMiner(12v/1A).This design let S3 run at much lower noise level.

6.Summary

We have to say that the design level of ANTMINER S3 is quite good.If the fans noise can be reduced,there will be better.
