Here some picture of my board that just arrived

And fan picture, i bet Gator-hex will be surprises

Bottom fan is "SUPER FAN" SUNON PMD1209PMB1A rated at 12,5 W, 4900 rpm & 57 dBA
Upper fan is SUNON PF92251V1-000U-S99 rated at 4,7 W, 4500 rpm & 46 dBA
After trying some setting:
Hex8A1 Chip Frequency : 250
Hex8A1 Chip Core Voltage : 980
Hex8A1 Set ASIC difficulty to one : 1
Ampere usage on 12 V rail is 30 A
Do you think about any replacement options? I'm still on the looks for good fans right now
BTW: 30 A are quite ok, so you get approximately 1,44W/GH with this settings ,right? (i have avg 250GH/s)
