Well, I'm new at overclocking, but I did buy a 1.6a & P4B533-E combination so that I could try overclocking for the first time. Well, right now I'm at 2159.99mhz @ 135fsb. My CPU temps have not gone above 26C. So my question is... when should I start worrying about the temp getting too high? And when do I know when to adjust my voltage?
