CPU temps: how hot is too hot?

I'm now leaning toward a Northwood 3.0 or 3.2 P4 for the system I plan to build in early '05. (Maybe with the D875PBX Intel mboard.) But some Newegg customers write that even these Northwood chips run hot. That concerns me. I want to select components likely to run cool; I want reliability and compatibility.

Generally speaking, how hot is too hot in chip temps? 50C? 60C? And what temperature range is considered ideal?

Also, although I'm leaning toward Intel, do Athlon 64s generally run cooler?

  1. Northwood will idle around 35C and may hit 50C under load with stock cooling. Overclocking will heat it up 5 - 10C.

  2. Northwoods are getting rarer and rarer as weeks go by, chances are you won't find anything but Prescotts by early 2005.

    Athlon 64 run much cooler than their Intel counterparts, some sources reported that A64s on 90nm generate even less heat, those should be readily available in 2005.

  3. If it gets to hot then that is Intels problem. U'll be getting an Intel mobo (on which you cannot overclock) and intel chip with stock intel heatsink. Chips can get to 70C and a bit more whitout being harmed it's when you overclock that high temperatures are dangerous. My father has 4 HP computers in his pharmacy with 3 ghz intels inside they run at 60 C idle (at least I think they are more or less idle). That how HP sells their stuff. So if I were u don't worry about the heat as long as you installed yout stoch HSF correctly ur ok. Worrying about heat is something overclockers do and should but not you.

  4. >>If it gets to hot then that is Intels problem.<<

    No it ain't, it becomes your problem, because it's your machine and you're the one who needs it. I've been going through hell with my Prescott, and my suggestion is to stay FAR away from Intels and go AMD.
  5. Lol ur right but still the cpu will do it's job, it's only reviewers and the likes of us that complain. People that buy one of these things just put it somewhere and use it until they buy their next computer wondering why they don't have that high heating bills :-p . It's not beacause the chips runs hot that it doen't function does it.

  6. Right, everyone should break a sweat, when playing football. Even if it is on the computer.
  7. Thanks for writing, everyone. Maybe I'll look at an Athlon rig. I don't know as much as most posters here, but even I know that heat isn't a good friend of computer components.
  8. Your Dad has 4 Prescott CPU's and not Northwoods. No Northwood in the world idles at 60C! It's amazing how answering a simple question about Northwood temps can bring out 50 dickless flag-waving Kerry-loving AMD fanboys who don't know the difference between a Prescott and a Northwood and make BS statements like, "Northwoods are getting hard to find, DooD!" Why don't you guys go get laid and STFU!
