[Doctor Who] The Meta-Crisis Doctor was practically human -- lifespan, one heart etc. -- but with a Time Lord mind. Then why was Donna "burning up", while he was absolutely fine?

Both the Doctor-Donna and the Meta-Crisis seemed to be similar, in terms of their biology and physiology. Therefore, shouldn't the Meta-Crisis be "burning up" from having a Time Lord mind?

The MC Doctor grew out of a Time Lord hand, he's got a hybrid body like Jenny. Donna is purely human in body, a beige PC case that's had a GTX 1080 Ti graphics card put in it and is struggling to deal with the power it needs and the heat it puts out.
