Cyper, I don't think blowing across the unit will make a big difference if you close the case. Right now you are bringing fresh air onto that board. Why don't you just strap that fan onto the heatsink on the open side working with the other fan, or switch the location of that board to one of the front slots where they get cold air from the big fans on the front. Otherwise, you could always cut a big hole on the side of the case and mount it properly.
Avenger, I didn't notice you set me straight, all I saw was some lame ad-hominem attack from a sad little boy and didn't need to respond to it. From reading your posts i honestly pity you, it must be hard to live your angry life... You probably need to go outside more, get some fresh air and sunlight.
Bitcoinorama! Good to see you again. Any idea when tuning software will arrive for November units?
I attached exhaust fans to the front grill on the inside of my case. I just wired them up to the grill. It really helps to quickly pull the hot air out of the case. I can't understand why KNC didn't do that in the first place. All PCs use a push-pull configuration for air circulation. So why not do the same for an equally hot ASIC miner?
