Here the Update after overclocking and adding Heatsink's to the ASCI Chips (64) and the Converter chips ( 8 )
http://s26.postimg.org/9o51g751x/Antminer_Status.jpghttp://s26.postimg.org/fb1edo7kl/CAM00448.jpgDue to my config I only get 0.69% Hardware errors and stay @42 Degrees C
Here again the Error rate Formula: Error % = HW / ( HW + DiffA + DiffR) * 100
PS: Not a Delta Fan connected wait for my 50W controller

but with the stock fan and a cheap 120mm out of a old Tower I get down to 42. Guess for -3 degree with the delta it's not worth it when I see people OC temp of close to 50
