Originally I had posted this info on KnCMiner form while bitcointalk was down. Feel free to post your own details as respects your experience with your hardware.

I wish to start of by congratulating the KnCMiner team on the success of their project.

In the case of the spec of the unit they have indeed underpromise and overdeliver.

Below are my first impressions of the Jupiter unit that I had ordered. I will continue to post my observations and results as to performance comparable with other ASIC hardware available today on the market.

Build Quality

Pro:

The unit itself is extremely light compared to what I have grown accustom to.

The case itself including the contents is well packaged together. The heatsinks on the individual boards are secure and snug to the lid with the help of foam pads.

There's two metal plates on the lid that helps move wind threw the unit out the back.

System runs very quiet with the low rpm fans.

Cons:

The stock fans are in my opinion do not provide adequate CFM.

The air intake is in the same location where the cables connect.


Performance and Power Consumption

The stock firmware that had shipped with my unit v0.90 pushed the chips into the high 600 GH/s Range and pulled 860 watts @120v. However due to hardware errors they average performance was 490 GH/s.

Upgrading to v2 0.92 the power consumption dropped from 860 watts, to 570 watts at 120V power. However due to poor ventilation cg miner reports 530 Gh/s average however due to the hardware errors the performance is the same as before at about 490-500 GH/s.

Software

Pro: If you had provided the correct information on your account before shipping then the unit will come preconfigured and ready to go.
Just plug in to your internet and power and your up at 100%.

Cons: I recommend that all persons open up the unit in order to check for loose fans. Seems a little bump can make the fans detach from the heatsinks. It is fairly simple to attach the fans.

Shipping

I was pleasantly surprised when UPS had shipped my unit on time.

Shipped October 2nd and Arrived October 4th.

Another colleague had issues with his order getting misplaced by UPS. However in the end UPS did deliver the unit on time.


Overall impressions

The case design a 8/10
This is due to the connection points and the inadequate stock ventilation for the speed setting of the ASIC processors.

The web interface a 5/10.
The web interface needs to include access to the cgminer log and perhaps poll the details from cgminer onto a page that the average user can use.

The software pre configuration 10/10.
As long as you had provided the needed information to connect to your pool of choice then the system should come ready to mine.

Here is a screenshot of the Jupiter 1 performance. This also includes other units operating in the same environment at the same electrical service.

Ambient room temp is 62.6°Ft or 17°C



Note:

I would just like to add that KnCMiner team has provided an excellent product overall that will help those entering the mining segment with a solid option.

Later on I will be posting screenshots of performance improvements that I will be conducting over the course of the next few days.

Very nice pics!!!!!!!!!  Wink  Thank you !!!!!!!!!!  Cool

Only some snap together stuff popped off in shipping Huh Not bad,could be alot worse,look at some of the Avalon stories  Roll Eyes

Decent looking rig,I may look into one if the price drops by at least 25%  Wink  The "next gen" 28nm stuff will use alot less power.

Congrats & happy mining !!!!!!!!!!!!!  Wink

I touched those VRM modules, they are very hot, so some kind of cooling should be provided, but the case fan is too weak, not even match the avalon's 120MM fan, but so far I have not find a 140mm fan providing enough airflow, they are all weak and quiet case fans

I agree. I have a few spare avalon fans that I will be swapping with the two front fans.

This is the improved results with just the case cover removed and an external fan blowing air over all the components.

Before airflow management change and firmware upgrade from stock v0.90

After airflow management Change and upgrade to firmware v0.92

How can you mount 120mm fan on 140mm holes?

I will have to use tie wraps just to test how the increased cfm helps cool the unit.

This is only a result of the firmware upgrade  Roll Eyes And that 15% hardware error rate is scaring Shocked

sorry for bothering you again but I have to restate my two questions
(see https://bitcointalk.org/index.php?topic=170332.msg3291576#msg3291576)

so you're going to replace this two front fans (https://i.imgur.com/DrBQn0G.jpg), right?

what is the exact type/model/brans of the avalon fans you're referring to?

thanks

Here is an update with comparable results from original firmware and airflow to the new Setup and Firmware v0.93.





So far no cgminer restarts.

This is results with still open case and single fan placed on top of unit facing down to dissipate heat off the boards.

Thats a good permanent solution. Thank you for the link.

I will first try and see if it helps before going full custom.

NP ! fans are my bag, been through so many types when finding the best for my watercooling setup. highest 140mm fan I've seen pushes 140CFM - Yateloon D14SH-12 http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=36_316&products_id=27361
