I was having problems with stability when I raised it to 2.5ghz so I've rolled it back to 2.4ghz. I also found a space heater and turned of the heater and am using it as a fan, my cpu can get as low at 24*C now, the heatsink is actually cool to the touch.
I haven't overclocked the ram or run 3dmark yet. I will be doing try them tonight. Prime95 ran for 10 hours no errors last night so I think I've stabilized it.
