Thank you for posting you power supply pictures. Your unit is using a different power supply the our BTmine units, who manufactured yours and how is the quality? Can you post more images of your Avalon clone.

Thank you

Your fan speeds are excellent, is this with stock or upgraded power supplies.

What fan speeds are you seeing on your units. I am getting 2880 rpm on the upgraded power unit running at 1500 mhz. My other three units with the factory power supplies just can not keep the fan speeds up and I an running them under clocked until my other eight upgrade power supplies arrive. They are all running fan speeds at about 2280 rpm, if I raise the mhz the fans speeds drop and eventually quit due to the weak factory power supplies! One is still sitting cold just our of the box, waiting for the power supplies to arrive.

Just wondering what is the best setup of fan speed that everyone is going for ?
Me after 3 weeks with my machines, the best combination for me is:

Chip Frequency(Default: 300) 1300 or 1400 (1500 drain too much energy, and increase the % of error too much so no point
Target Temperature: 65
Overheat Cut Off Temperature: 75
More Options(Default: quiet): --avalon-fan 20-20

These setup are giving me:
Temp1: 25
Temp2: 65
Temp3: -1

Yep, there's no way you're going to be able to run at 1500 with those temps at that fan speed. If I don't do anything to the fan speed, I'm at 29 and 41 and I can run 1500 no problem with about 4% error, which is perfectly fine.

Here are my Fan Speed: (all at 1300Frequency) Room temperature 22/25°C
Machine 1=> Fan1:4080 / Fan2:3480 / Fan3:3360
Machine 2=> Fan1:3120 / Fan2:3120 / Fan3:3240
Machine 3=> Fan1:3240 / Fan2:3420 / Fan3:3360
Machine 4=> Fan1:3240 / Fan2:3120 / Fan3:3240

I am using the original power supply.

Power (i measured a maximum of 1050W)

Hi back,
So for the factory i can only know the name in Chinese and the factory is located in Shenzhen.
(PM Me if interested and i will share the contact person if you want),
I am living in Hong Kong, so i went directly there to make sure it was legit and properly working (checked 4 factories before buying anything and found this one was much better than the other 3).
What kind of photos do you want to see ? Because honestly they all look the same pretty much. Just mine inside is extremely clean (all the cables are properly binded together, no missing screw, ) If you want anything specific let me know and i will try to take some photo for you.

So yes overall i am extremely happy with the quality.
I bought total 8 of them, and using actually only 4 of them for around a month now (because of power limitations in the warehouse i am running them).
So I just sold one machine 3days ago and shipped it already, and still have potentially 3 for sale (still hesitating to find a place to run them instead, but because of the noise and the power needed it's not that easy here in Hong Kong).
