ok i got a p4 3.0ghz hyperthreading cpu can anyone tell mw aht the maximum and minimum temps should be plz cos i run at 52oc up to 68oc

With the amount of information you offer here, I'd have to say your temps are OK.

What processor, motherboard, heatsink and fan? How much of an overclock? Did you raise the vcore? What are case temps? What is ambient temperature? Poor, mediocre, or good case ventilation?
