I began overclocking my e4300 and I've got it up to 2700mhz, but I'm concerned my temps are high. I'm idling at 49-50 degrees and going up to 70-71 under load. Is this too high? I've bumped the voltages up slightly because I wasn't stable at stock, and I think I can get more out of it, but I'm just not sure what temperatures to keep it under.
