Okay, I know how to over clock and everything, I've got the Noctua NH-D14 CPU cooler, with arctic 5 silver. After OCing to 4.0, my idle temps were around 45.. When I ran prime95 for about a minute or two, it got up to around 90-100.. I figured thats okay, because most times CPU wont be stressed that much, so I bumped it up to 4.2ghz. Its still the same, around 45-50 idle, and it quickly jumps to 100 when I start it.. Is that too high, and is there any reason its that high, if so how can I lower it? (Do voltages have to do anything with that, like if I lower voltages, will it bring the temp down?) Thanks
