After shoveling tons of rocks and doing other yardwork, my step dad agreed to buy me the Cooler I mentioned in the thread title. I want to change from the stock cooling I've been using since I bought my computer, to get better temperatures but mostly to overclock a bit. How high of an overclock should I expect in an NZXT Source 210 case with no extra fans, on the Gigabyte GA-970A-D3P motherboard? I want to at least get over 4GHz, above 4.5 if possible.
