Simple Method to Overclock i5-3570K Processor?

My PC hardware is:

Gigabyte GA-Z77X-UD5H motherboard
Intel i5-3570K CPU & Noctua cooling fan on Normal BIOS profile
16MB GSkill memory

I've just started experimenting with overclocking and found this simple approach which increases the Turbo ratios https://www.youtube.com/watch?v=3L0EOCWWeIQ

I've obtained a stable overclock by setting the Turbo ratios to x42 and CPU PLL to 1.65V. All other settings are on Auto.

At this setting the PC runs the Intel Burn Test at 77C and the Prime 95 Blend Test at 66C which I understand is quite reasonable.

However, if I increase the Turbo ratios above 42 , I have to terminate the Intel Burn Test since the temperature ramps up above 90C and I get an audible CPU warning.

Has anyone any tips on how to achieve a higher stable clock by increasing the Turbo ratios. I'm aiming for a stable, reasonably quiet overclock.

A really good cooler and watch the voltage (that you can provide enough), basic tips ;)

I noted the VCORE voltage on the Auto setting increases to 1.306V under load whereas Google research suggest 1.25V should be OK. How do I limit the VCORE voltage under load but let it drop to the standard setting when idle?
