I guess you wont read anything from burnin today... *g* Looks like he has some things to play with... (Sorry for spoilering burnin... Wink

(though one could guess anyway that they reach today))

Correct, I will do some initial tests dead-bug style.

There they are:

That's some sexy picture.

He hasn't received the PCBs yet...

I thought he can do tests with the chips alone too. With prototyping boards. But im no technician so far.

Hmm, read about KNC, but never looked at their setup. Guess we think alike. Grin

(Anyone got a link to their designs?)

Heatsinks are "custom". Plenty of room. Fan is 120mm. Wiring can be routed through side slots.
Of course it's all prototype until the boards ship.

In my unprofessional opinion your design

is far superior to KNCs

for a number of reasons. Two of them are: less cabling and far less mechanical parts, which will, beyond a doubt, fail sooner or later.

Your cooler fins could start low at the side and grow higher to the middle, like this you could suck out a substantial mass of hot air fast.

Thanks.

A heatsink could be manufactured like that, but cost vs benefit isn't worth it, IMHO. We've hashed through the temp calcs in the Klondike thread and due to the low W per chip, virtually any heatsink design will be more than capable to cool these boards. Unless OC'ing becomes a factor later; a cheaper, simpler design is the way to go for now. But in the future, who knows?

looking at those gaps between PCBs - I think one more can fit in - a pentagram would create nice devil's machine

Yes! And it could be stacked like a beehive.

burnin before opening orders please post up if you can the last final prices in order to get the money ready

Also post some power supplies or have some ready to order. I wouldn't want to have boards in hand but no power supply. Thank you.

Where are you from? I would suggest to get your power supply yourself. There is a pcie connector if i remember correctly, so buying a atx psu sould be suitable, depending on how many boards you will power.

Burnin, do you think 12v 15A power supply will be fine for 3 boards?
Your specs say each board with 20 chips will draw approx. 40W, that is 3.33A @ 12v, so for 3 boards it would be exactly 10A, so 15A power supply should handle it fine... I was thinking about something like this: http://www.ebay.co.uk/itm/DC-12V-15A-180W-Switch-Power-Supply-Driver-For-LED-Strip-Light-Display-220V-4-/200725152098?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item2ebc26c162

Yep KNC design but its so optimal for save time and space to assembly

Sure, i was only drawing six because i got tired Grin

you can use a one-size-fits-all case, providing space for 8 pieces. If you only have 2 this is not the perfect case for you, but with 4+ you can get either more space between each or simply use half of the case, putting other stuff in the other half. A shee-metal bend to the form of a U with screws coming from the sides would provide a fitting for any possible combination (every second slot is used, every third or whatev you like). Maybe this couldbe considered

also you can make a case for 4 units, if you need to stack 8 just put another one next to it.

I've been messing around with a 4 board, single 120mm fan arrangement:

looooll...design by KNC ;-) ..but really not bad....

cause of security reasons, such a device need a full case around...my opinion
And i think that the heatsinks will not have enough space. Look at brunin's ones
