6700k Overclocking

Been on my 'new' machine for about a week now and starting to think about overclocking.

i7 6700k @ stock atm
Maximus VIII Hero
R9 295X2
16GB Corsair Dominator Platinum 2400mhz
Corsair AX1200 PSU

At this second the CPU is running at 26C.

What do you all recommend trying? I'm not really a tinkerer when it comes to overclocking i usually tend to find somewhere I like and just stop once i know its stable lol. I don't want anything crazy just a nice 24/7 overclock.

My 6600K runs at default voltage @4.2GHz on CPU and cache. It's frequency at which I'm testing all memory kits and it's enough for me. You can probably keep low voltage up to ~4.5-4.6GHz without playing with other settings.

What cooler?
What is the load vCore?
What are the load temps?
