How hot is hot?

I'd like to ask advice on the following:

1.) Mobo Intel 865PERL & P4-3E: processor idle temp ~47ºC/50ºC, with load ~60ºC/64ºC, temp in other zones of the mobo (idle/loaded) zone1 ~35ºC/43ºC & zone2 ~40ºC/52ºC... would you consider this "acceptably normal"?. I know the cooler the better, but I am not paranoic about it. I just want to know if these could be considered acceptable.

2.) Under certain circumstances (f.e. resizing a few thousands JPG images, that is, with CPU quite active -nearly 90 or 100%- for let's say five minutes) CPU keeps getting hoter and hoter... up to 66ºC/70ºC. Then when this particular task is over, it gradually reduces to 50ish. This is also normal (getting "that" hot), isn't it?. And I should not worry in excess if it ocasionally reaches 68/70 for a few seconds/minutes, should I?. This only happens with very specific tasks (the ones really processor-intensive I guess). Again, I am not a cooling paranoic, I just want to make sure I am not unknowingly frying my PC.

3.) I read at the Intel webpage I should deactivate hyper-threading in my Intel 865PERL mobo if my OS is not XP. (http://www.intel.com/support/processors/sb/CS-017343.htm). Actually mine is W2K Server. Although I understand the (very) basic idea behind HT I don't quite grasp what HT really does or how it works, therefore I can't really assess if Intel is "exagerating" or indeed if I SHOULD deactivate it. Any chance you can advise here?.

BTW: Due to space restrictions I have my PC in a flat box -can't switch to minitower!. I've applied AC5 in my processor/heatsink and I have three internal fans with a decent (!) airflow... actually, the best I could do considering.

I'm no newbie, short responses will suffice.

Thanks a lot.
 
your fine

i had a p 4 3.2 E clocked to 3.9 GHz before my AMD and it maxed at 65 c with load to called intel thay said your fine at a 70 c operating temp you will get 2 years out of the chip max after two years that chip will be a thing of the past lol. so clock that SOB and have fun . O thay said do not go past 85 c or kiss it good buy.
 
If you are running 60C+ for hours on end i think that's too hot personally. It shouldn't damage anything in your computer, but you PC becomes a little oven for your room and if running for an hour or more easily reaches 70C+ i bet. 50C-60C is normal for stock cooling i believe (load temp) but anything above that i would get better cooling if you plan on running your PC over night.

With the AS5 make sure you put the right amount on there. Aplying too much/little coudld give you worse temps actually. Just a thin layer shoud do it, and after a day or 2 of running you might notice a few C drop if the cooling b4 was really bad.
 
HT is okay to stay on for win2k server. Intel says turn it off if you don't run XP because they expect home users to use win98 or XP and win98 is flakey when running 2 threads
 
I use 2000 pro and just bought an Intel 3.4 Prescott. I had heard of these processors becoming quite hot, so i bought with it, an Asus 4 in 1 fan specifically made for cooling the cpu. I get my computer sometime this week so ill check how well the fan works so i can recommend it (or not). I also heard the Asus P5AD2 Premium MB which i also bought keeps the cpu pretty cool as well with their Q-Fan2 and Stack Cool™ Technology. If it ever goes over 55 degrees though, ill be pissed.
 
the P5* boards from asus are a different socket than the 865PERL. LGA775 was designed to fix the S478 prescott heat problems because it passes the same voltage through more contacts. A 3.4 will probably pass 50 under load, I don't know about 55 though. Q-Fan does nothing to keep the processor cool, it's just a noise reduction feature, lowering the CPU fans RPM when its not needed to cool it. Stackcool cools the motherboard voltage control circuitry (this is my understanding of it, not what the marketers say) so you can run higher voltages without overheating the regulators too badly

And sometimes when it is needed :P The StarICE cooler is very nice however :)
