FIRST PRE TESTING RESULTS / PRE BETA
Hi Everybody, I'm happy to report that everything is going fairly well and that the first results are positive.
I so far mounted 4 Cards (7950 Gigabyte WF3 with F43 BIOS, BAMT), 5th coming this afternoon. I found the following.
Depending on ambient air temperature (tested at 17-18C outside), I got the thing stable at 67C-72C, 1080W. Hashes average for testing 580-600 kH/s .
For cooling, I used a 24" industrial fan (low speed) which only really pushes air on the edge (design flaw), which is not good at all. It seems a shroud would help a lot to push the air in between the cards and not around the frame.
I'm going to see if I can get some space to allow the cards to stay correctly positioned. Right now, I used a foam spacer otherwise some of them touches (you'll understand when you see the pictures).
Posting again soon.

The 5 cards setup so far. Waiting for #6 and some special parts to customize the rack.



Just a note.   Some of us here honestly trying to offer you suggestions have studied heat transfer and worked in the field.

And yes, it is rocket science.

Hi everybody,

I'm open to all suggestions. But I would like the parts we use to build the frame to be widely available.

Extracting 4000-5000W of heat is not going to be easy, no doubt about that. The air cooling is going to be the hardest way to do so, and this is why I'm looking at various options. I just order this fan:
http://www.ebay.com/itm/01-05-Chrysler-PT-Cruiser-Radiator-Cooling-Fan-Assembly-NEW-/130632543695?pt=Motors_Car_Truck_Parts_Accessories&fits=Make%3AChrysler&hash=item1e6a4e6dcf&vxp=mtr
http://i.ebayimg.com/t/01-05-Chrysler-PT-Cruiser-Radiator-Cooling-Fan-Assembly-NEW-/00/s/MTIwMFgxMjAw/z/TnIAAMXQuu9RjLtl/$T2eC16R,!zcE9s4g3JJwBRjLtlIWq!~~60_57.JPG
I will give it a try and see how well it performs.
Here is what I found for it:
Cooling Fan Assembly with Ø415mm Universal, Suitable for Chrysler PT Cruiser
# Power: 150 and 180W
# DC voltage: 12V
So I can expect it to pull roughly 15A.
I'll run a few test and report back as soon as I get some results!

Lol thats really impressive..

But its funny to see high end cards of that quantity and variety being loaded on Windows 98.. should be hack proof though.. i dont think anyone in this current era of hackers would even know what to do with it?
