Newbie overclock questions.

I recently built a budget system using a Pentium Haswell G3258 @ 3.2GHz stock speed, and an MSI H81 mobo.

I found out the CPU is unlocked, so to overclock all I apparently had to do was enter my BIOS and use a utility to increase the CPU ratio.

I set it at 40 (40 x 100MGz) and it now displays my CPU frequency at 4.0GHz both in BIOS and Windows.

I know there are different methods to overclock, but this almost seems too easy. Is that really all there is to it?

I left the voltages on "auto" and hope the board can figure it out. The system seems stable and I do notice the faster speed.

I played some games and then checked the CPU temp at it was at 42C.

I know these new Haswell chips runs pretty cool, so do you think I can survive for a while with stock air cooling?

Is there any chance I could go beyond 4.0GHz and still use stock cooling?
 
General rule of thumb with alot of people is to never trust auto voltage, especially when overclocking.....However ive been out of the OC game since my SR2 (Nehelem chips....) since im on 2p's now without the ability ..... So i could be wrong.
 
You can get away with the automatic voltage if it is not running too hot, to properly test the max temps that you could download Prime95 to stress the CPU and RealTempGT or HWMonitor to check the temperatures, run tests and see how hot it is running. If you want to go more deep into optimizing the voltage to get better temps and better efficiency you can download CPU-Z to monitor the voltage that is being applied to the CPU on auto while under stress (Prime95) and in small -0.010 or -0.005 steps manually bring it down and run Prime95, continue the process until it is no longer stable, then bring it back up a little. It is very important to monitor temperatures, should keep it at around 70 degrees max.
