new prescott heat problem

[dunnleed08]

hey i just updated my system which is now a p4 prescott(stock cooler) on a abit is-10 mobo, centurion 540 case, dual cd drives, ide 140gb drive and an 9800 pro all-in-wonder.....my abit eq temp monitoring prog. says that the pwm is 45, cpu 30, and sys 35 celsius while on idle which is pretty good from what i know......but when under a heavy load it goes to(( pwm 65to75, cpu 40-50 and sys 40) is this good, bad, i just don't know...75 certainly seems pretty high to me(even though i really don'r know what pwm stands for, anyway, if somebody could help out a poor ignorant idiot, it would be much appreciated

old school cpus, cross 70 and dont expect it to run for long

but for some reason, prescotts are designed to work at load between 60 and 80 degrees, they have a maximum temperature tolerance of 120, which i wouldnt test, if you fear for your processor, get a good heatsink like an XP90C from thermalright, but dont worry, prescotts are ment to run hot, i would worry more about my electric bill then the temperature of that processor, that heat is disipaded energy.

PWM stands for pulse width modulation, it's a way to lower DC voltages with low power loss. It basically takes 12V from your PSU and converts it to whatever Vcore you are running your CPU at. All it is is a collection of MOSFETs that do power conversion so as long as they stay under 120 C or thereabouts you should be ok.

thanks

that's a hugh load of my mind...i have this new cpu, and i've been afraid to use it.....with my old p4 2.2 70 degrees on the pwm never even came close to coming up....
