What's a good CPU stock temp?

i am currently sitting down and looking at the hardware monitor in my bios on my new build (no OS installed yet) and it is currently sitting at an idle temp of 44 - 45.5 degrees celsius. I don't know if that is good or bad. I have three chassis fans, a PSU fan and a CPU fan all blowing at once... i would've thought it would be cooler than that considering my room is chilly. Anyway, just wondering if that is a good, stable temp.

More about what good stock temp
  1. 12 to 15 degrees C above ambient (the temp of the room) ... at idle with +15 to 20 more under load.
  2. The more important temp is the one under load.

    Runn OCCT or Prime95 and watch your temps.

    45C aint great but it depends what your cpu is?
  3. Intel Core i5 650 3.2GHz
  4. 45 C idling in the BIOS is pretty high. What kind of case, meaning how is the airflow through it?
