would an h70 work with an intel i5 5.0 2600K?
For a start its an i7, also you can not be sure your CPU of choice will hit 5 ghz, if your asking if a H70 will cope with the heat from a highly OCd i7 2600k, then yes it will if you have it installed in a well ventilated case, but for a high OC such as which you desire for both CPU choices you would be better served with either a H100 or a high end air cooler such as the Noctua NH-D 14 or the BeQuiet Dark Rock PRO.
