i have to say thanks to Mr Teal and ChipGeek again Smiley
I wish i was able to get 2 of these and ditch my BFL 30GH so it would fit nicer in my pc case at work but oh well

I went the cheap option and got a slim heatsink + fan + thermal pad
This was the only option really for me as the BFL 30GH takes up so much room in the pc case that im using that i had to go for the slim profile look. the case runs cold anyway so i do not think that heat will be a problem. If anything does arise from it i will just have to add a extra fan in to the case. I plan on fixing the case and make it a little bit better so the air flow goes threw it with out a problem. I'm thinking of taking the DVD ROM out of the case aswell and adding a fan in that area of the case so more flow goes around.

Anyone interested in a drop-dead simple open-air case for Chili boards?

[picture omitted - see above]

This basic design could be expanded to accommodate more boards (in either/or width and depth) and could be stacked.

Interesting, but I don't like the exhaust of one heatsink feeding into the next heatsink. I would expect better performance if you rotate those heatsinks 90 degrees and point one of  these bad boys at the rig to provide adequate the air circulation, lol.

Fixed.   Roll Eyes

Cost, if fully assembled and shipped to California?

The case is $29 plus shipping (from NH).  The final shipping weight is still tbd.

Anyone have pads left? Need enough for one 8 chip board.

And is this even an option? http://www.ebay.com/itm/LOCTITE-Thermal-Conductive-Pads-Self-adhesive-Phase-change-Interface-1-Foot-/331046544007?pt=US_Memory_Chipset_Cooling&hash=item4d13e96287

Or this? http://www.frozencpu.com/products/19922/thr-208/ATI_Original_Thermal_Adhesive_Tape_-_35mm_x_15mm_x_10_-_8_Pack.html

Anyone try using paste with success? Results?

Bitcoin miner... space heater... mood lighting...
Yes, I know fans should be turned 90 degrees. Didn't seem to make much difference. Running around 203GH/s w 6 boards and temps ranging between 52 and 69.

Now that a few people have hashing Chilis can someone provide feedback to allow people to get ready for batch 2 shipments.

-How big of an area of thermal mat/pad does each Chili Need (i.e. 2"x2")
-What cooler is best value (cooling per dollar spent).
-Were there any surprise parts that were needed to get the Chili hashing?

thanks in advance

The block is 25 BTC + Tx Fees.

You receive that if you are solo mining but if you are on a pool, it just goes in the pool and gets dispersed evenly from everyone that helped find it.

Less variation that way.

If you still have the FTDI driver, you can open up the comm port in  Hyperterm or Putty and type in ZCX, it will report the number of engines.

One Chili user on the BFL forum reported some great results using a Hyper212 Evo using some high grade thermal paste.

If you're lucky and your chips are very coplanar, you can get away with paste. But usually pad is required because of variance in chip levels.

If I had to guess, I'd say the biggest improvement in that setup is that each heatsink has two fans on them, not one. Adding a second fan is much easier than removing everything, applying a different type of thermal solution, and then putting it all back together.
