I removed wifi on my batch #2's on Thursday evening... have not cut/removed fused F1, yet. Wanted to report that the NEC usb hub chip is room temperature, to the touch (during hashing).
Leaving it alone, for now. Anyone else besides btclvr try the mod?
Batch#2 was shipped w/o antenna...
I've catched a thought last night that chip overheating could take a place when TP-LINK have enabled Wi-Fi module but missing antenna. If TP-LINK implements dynamic power calibration for Wi-Fi PHY lacking of antenna could force it drawing much more power hence USB-hub chip overheating. This is just my deduction though.
