I have just built my very first computer with a 6400 and so far I like it. Bear in mind this is the first day my computer was working. I would like to know how long to wait before I try to OC. I believe my current cpu temp is about 45 degrees Celsius. Would that have any impact as to how soon I should begin to OC. I also have a scythe infinity cooler that I intended to use but it was so big it was almost touching the NB chip set and was even closer to touching my exhaust fan. Should I use it in an attempt to cool my cpu further?
