Nice....
a18kiska - Im running the same 4u case as you on my 6th 8gpu build now..... Firstly sweeet build can i ask you a few questions...
What rack rails are you using for the 4u mining racks?
Whats the config of the 3 front internal fans blow out? or blow in? Take it you upgraded these? I went 3000rpm for those.
Whats the config of the AC Infinity using about each miner? Is the lid off? and what direction is the airflow?
Cheers
Rails:
https://www.amazon.com/gp/product/B01D3FJ5HC/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1All airflow goes in the front and out of the back.
The 3 front fans blow out at 5200RPM/240CFM. There are also two in the back running at 9000RPM/132CFM.
The lids are on, AC Infinity fans are reversed so they also blow out the back and remove any heat radiating from the lid. All of the heat is exhausted through the ceiling and, depending on success of this ICO, cold air will be moved through the floor and pulled up by the miners.
