Hi,

I need tips in overclocking this combo (haswell 4670k + asrock z87 pro3). The AssRock apparently has crappy power phase design and not-so-efficient VRM cooling etc. I'm planning to overclock with a Cooler Master EVO 212 Hyper CPU cooler.

If I bump up the multiplier a bit to get 4GHz, will the cooler do fine in term of temps? Is the stock voltage sufficient or can it go any lower?
