Depends on your board and cooling. The firmware changes voltage and per chip frequency in order to maximize performance while keeping temperature in check.

I've some spare thermal pad 11W/mk, $2 + shipping for each (shipping from California).
Payments via Paypal only, shipping same day via USPS.
Each piece is 37x33mm (you normally only need 33x33mm)
PM me for details and purchase.

(The thermal pad is this one: http://www.frozencpu.com/products/16878/thr-164/Fujipoly_Extreme_System_Builder_Thermal_Pad_-_14_Sheet_-_150_x_100_x_05_-_Thermal_Conductivity_110_WmK.html?id=BTEHkam2&mv_pc=312)


I still have some pad left, left me know!

These boards only have room for 8 Chips.

love the design, very clean, well thought out... /tip hat

doing quick math, that works out to about 4.5 btc + cooler for each 30GH board, right? Not counting cooler that's rougly a 4 month ROI, and that ROI is about to get much worse in Dec (8/mo) and Jan (11/mo).

I wish I'd had the option to buy this in August...

This issue on ROI comes up a lot. Is there actually any product available today which has a positive ROI?

Nothing at market will break even if 30-40% increase in difficulty every 10 days forever. Hardware buyer basically betting it won't increase 30-40% every 10 days forever.

Here are pictures of my adapter kit for mounting the Hyper 212 EVO to a Chili board. Since I don't have any boards in hand yet, I made a simple cardboard model.

(click to enlarge)


Notes:
* I recommend at least 3 full turns of the screws into the standoffs from each end for stability. If you assemble them as shown, the screws should meet right about in the middle of the standoff, about 4-5 threads (full turns) from each end.
* The number of washers inserted in the center of the X bracket affects the pressure on the chips/pads, though I'm not sure by how much. By my calculations, 2 or 3 washers should achieve the same pressure as the cooler would apply to a standard cpu with the stock hardware. The kit includes 4 washers for that location, so you can choose how many to use.
* The picture shows 4 pads, each 10x20mm, which you can cut in half to cover 8 chips. You can probably get away with not cutting them and covering 2 chips each if you position them very precisely. Make sure you remove the plastic from both sides of the pads.
* The 12mm long M+F standoffs I'm using for the board's feet, and their nuts, are the ones that come with the cooler and normally attach the backplate to the board.

I already sold all 17 parts kits I had for sale, but I still have thermal pads for 6 more boards, which I'll sell for $2 per board plus shipping.

Is anyone interested in these kits for batch 2? Let me know how many. I figure I can get more parts in as soon as Monday if there's enough interest (at least 25 kits to make it worthwhile).

At the moment the firmware goes for the maximum hashrate allowed for the cooling solution provided.  Colder - faster hashrate.  In the future, we'll release a new firmware that will further support underclocking to reduce power.  

As a couple of data points - in production we're using a TIM that is not very good but is very durable and Chili slows itself down to keep from overheating.  This gives around 20GH/s and under 150W.  But with a good TIM, we routinely are getting over 30GH/s and more than 150W.  Of course we cannot guarantee that speed for all boards, but it seems possible on the few we've tested.  Keeping the chips cool will get more hashrate.

Does anyone from forum really test the Board to tell us the real hashing speed and real watt per board?

The first picture - temp 1 is a single- the second is the Chili that stays 20c cooler
