yeah those tems seem fairly... no, really hot for a pentium, even under that stress... could be your HSF is the prob.... i've got a 2500Barton @2.2Ghz and i never go over 46C, usually am down in the low 40's tho. i use vantec aeroflow and arctic3silver. give a different hsf a try and see if your tems are still too high... also, make sure your case is giving enough fresh air to your cpu
