Is a personal opinion, I would like the thread is not filled with photos of products and things that are not our FPGAs.

The link alone would probably have been better suited.  Roll Eyes

two ztex boards, host and power supply pictured

two X6500 and 10 singles have been ordered

power supply will run it all - is already wired to the ztex with 12 volts and usb hub with 5 volts and running on p2pool

Some pics of the Bitcoin Syndicate FPGA Rig (it looks a little different now, I no longer use that motherboard, as it had USB chipset issues, and I have switched from the el-cheapo 4 port USB hubs to some nicer 10 port ones. Don't have updated pics yet though) lol




(these were posted elsewhere too just thought I'd add them to this thread since it's relevant) Smiley

Looks to be 18 Icarus so somewhere around 6Gh/s.  Smiley   nice!

Just out of curiosity, do you still need those small fans on the Icarus heatsinks? Wouldn't it be sufficient or even better to close the "case" on the top and force the air through the heatsinks?  What's the airflow (cfm) of these fans?
 
In case this is suited better for another thread, let me know.

No, that wouldn't work, the Icarus stock heatsinks are way too small for that and need quite a bit of airflow. Even a huge fan sitting next to them (but blowing from the side is barely sufficient, so at least the second-row boards wouldn't be happy with such a setup.

Sadly you can't easily swap the heatsinks on these boards...

I would think that the turbulence caused by perpendicular airflows would have lesser cooling capability than higher-velocity ducted flow that was relatively linear. So, fans in a push-pull and a cover on the case (clear plexi?) ought to give even better cooling.

Only if you put bigger heatsinks on them or prevent the air from flowing around the heatsinks.
These heatsinks provide way too much air resistance (partially due to the direction in which they are mounted), causing barely any air to flow through them. Their surface is way too small to cool the chips adequately at the low air speeds (within the heatsink) that you would end up with.
