  1. Yes it would easily the x40 outperforms d14
    The temps would be around 55 on full load
    Its dangerous after 65-70
  2. I got the x60 and OCed to 4.2 and getting temps around 73°C using Prime.
    I guess yours will be the same.


    Always depending on your chip of course.


    "Dangerous" is pretty subjective when it comes to overclocking...especially Haswell. ;)
    Let me put it like this: Your CPU will throttle at 105°C. Most overclockers try to stay under 80°C or in the low 80s at max.

    Will the lifespan of my CPU shorten? Even at 'safe' temperatures (55 C)

    Everything you do to or with your CPU will shorten its lifespan.
    Chances are you will upgrade your system before it dies.

    So, my advice: Make sure to stay below 1.3V vcore and below 75°C-80°C under Prime.
    That way your temps will be more than safe under day to day use (gaming etc.).
