First time overclocking a CPU, need some advice

Hello there! I plan on overclocking the CPU in the build down below. I would like to gain some knowledge about overclocking. So here is a list of questions that I have:

1: What are safe/stable idle temps on a CPU (before or after overclock) and what are considered normal CPU temps while under pressure?

2: Once I hit a stable clock, is it ok to raise the voltage a little higher to see how far I can push it, or is there a safe voltage that I shouldn't try to go beyond? I have a pretty beast cooler so I am curious if there is a point in time in which I should stop raising it.

3: When overclocking a CPU, you're generally just increasing the clock speed/voltage, yes? Or is there more to it?

4: Turbo Boost, Yes or no?

5: Safety tips so I don't destroy my computer. Even the obvious ones.

My soon-to-be first build - http://pcpartpicker.com/p/wNxTf7

Any help is appreciated.

    Better CPU cooler. Not loud, good cooling.
    Better ram resulting in a raise in minimum fps.
    Higher clocked GPU.
    cheaper PSU still suitable to sli

    To the OP:

    1. idle: under 45, load: under 85
    2. If you keep your temps low enough, any voltage should suit. Note that it will reduce lifespan.
    3. No. There are other settings you need to mess with like uncore, other voltages, ect.
    4. NO

    Already bought the RAM and the cooler. You sure 750W will be good enough for 2-way SLI overclocked 970s+CPU?
  3. yes
