As an addendum to my last reply, it's important to note that i'm really happy so far with the SP20's and the hash rates they are putting out.
I'm just curious about finding how and why they tick and finding the balance between power draw and hashing rates.

Given the progress i made from advice in another thread running 2 SP20's from 2 PSU's and finding a happy medium that'll be the way forward, it's simple curiosity that's got me asking how and why these things work and what they could do with excessive cooling. Especially until i need to pay for the power! At that time, it'll be low and slow
