Re: q6600 what's too hot?
If I'm not mistaken B3 steppings are rated up to 62.5C so I wouldn't even worry about it until you get upwards of 60+C and even then there usually reserve left from advertised specs.
Mine runs around 55C at 3.2ghz quad orthos prime at priority 8 with 120 ultra air cooling and a fairly quiet fan.
