Is prime real stress of the CPU?
Q: I mean . Ive been running since 6:00 . 1:30 p.m. are here . and the temp is still 41C, almost the same as idle temp .
Best Answer: 60-70C should be about the max. Yes, I recommend an aftermarket cooler.
If all of the stock CPU fans were good enough under all circumstances there wouldn't be any aftermarket fans.
The stock ones are ok in most circumstances but your's doesn't seem to be one of those circumstances.
However, you can re-evaluate your current air flow. This involves balancing the exhaust fans and in intake fans. 5 80mm fans isn't really as much as it sounds. I have 2 120mm exhaust fans, 2 120mm intake fans + 1 80mm intake blowing on the graphics card. And I use the highest airflow (cfm) I could find. I like the Scythe fans. I also use a fan speed controller to get effective cooling with the least noise level.
The concept is that you want high exhaust volume because you won't cool anything if you can't suck the heat out. Then you want just a little bit more total air intake volume than exhaust.
The reason for more intake than exhaust is that you should be running filters on your intake fans. When you have a little more intake than exhaust, you have what they call 'positive pressure' inside the case and then you know that all the air getting into your PC passes through the filters. When you have more exhaust than intake, the extra air comes in unfiltered through any crack and especially through you optical drives and any other opening. Filters and positive air pressure keeps it clean. Big exhaust keeps it cool.
Good Luck.

You'll have a nice little barbecue with S&M too. Lots of good tools here, scroll down to S&M: http://www.benchmarkhq.ru/english.html?/be_cpu.html
Totally agree with that. If I stress my Newcastle with that program, my temps go up to:
72C :Q at stock 2 Ghz / stock 1.5 VID (actual vcore 1.56),
69C at 2 ghz / 1.45 VID (vcore 1.5 – exact Newcastle default)
and 59C at 2 ghz /1.3 VID (vcore 1.35 – almost lowest stable).
So yea, it really does make your computer a space heater.

Re:Try the cpuburn utility. It always heats up the cpu more for me.

Well, that's AMDs 90nm process for ya! Those lower clocked 90nm A64 hardly heat up if you have reasonable cooling. I've noticed this on my brothers overclocked Sempron. Even at 2.2GHz, no case cooling and stock HSF, it still hovers around just 45C under full load. Idle isn't much lower.
But, yes, Prime95 definately loads the CPU. Mine usually gets 2-3 degrees hotter than when gaming.
Nice to hear that…
Im OCing this 3200+ to 2500Mhz @stock voltage and @stock cooling
Thanks for the answers

Re:hmm its a possibility if you are running stock volts.. try S&M if you want to get you CPU toasty
