depends on the computer... most Athlon's run from 90 -120 anything over aout 130 i think i'd be worried about...

The maximum safe operating temperature of an AMD Athlon is 90 C. That means that as long as the CPU is under 90 C, it will run. It may not run reliably, but it will run. Once it gets above that, then AMD no longer guarantees the safe operation of the CPU.
Note, however, that today's motherboards do not actually read the core temperature of AMD processors. Instead, the thermistor measures the air temperature below the CPU, so it is always less than the core temperature. Some motherboard manufacturers, like Asus, have offset the temperatures to more realistically reflect the core temperature, but no motherboard thermistors are completely accurate.
Most AMD processors today run between 40 and 50 C, as measured by the thermistor. As a rule of thumb, anything under 60 C is acceptable, anything under 50 C is good, and anything under 40 C is excellent. Of course, this changes from motherboard to motherboard, but generally those numbers apply to most cases.
Intel processors, on the other hand, tend to run cooler. I do not know the maximum safe operating temperature of Intel CPUs, but Pentiums and Celerons do run 5-20 C lower than AMD processors. Most P3s rarely get above 40 C, and many P4s stay around 40-45 C. Also, I believe that Intel processors have an on-core thermal diode, so the temperature is the actual core temperature. Thus, if an INtel Pentium 4 and an AMD Athlon were both running at 42 C, the Athlon's core would still be hotter because the AMD is not accurately measured.
Sorry about my long-winded reply. I am sure I answered your question in much greater detail than you wished. What can I say? I tend to wax lengthy on this subject.

thanx, your reply was very helpful

I run an Athlon 1.4 and I have it at a steady 45C after about 2 hours it gets to that temp. After that it doesnt get any hotter. now, once after running it 1.8 ghz and only 3 fans (now i have 6) it got to 86C and it just froze itself. But.... get water cooling if you can afford it ! then you can overclock it!

Please note that the 90C temp is an ABSOLUTE MAXIMUM. You NEVER want it to get anywhere near that. Transistor junctions quickly deteriorate above that temp and the life span of the CPU if shortened by temperatures anywhere near it.
REALISTICALLY I would never want to see a CPU run hotter than 60 C. Most motherboard temp alarms go off around 70 C and most mobos are setup from the factory to throttle down at 80 C.
Onboard temperature probes are notoriously unreliable so don't take the temperature you see on Motherboard Monitor on faith. Use it as a basis to judge safe operating temp.
For example from long experience I know my CPU runs at around 35 C at idle at 50 C while playing a 3D game. I don't necessarily believe that's the real temp, but since I know that's the normal temps displayed for this system, I'd be concerned if I see it go much higher than 55C.

Sorry to bring an old thread out of the dead, but I am running an Athlon 1.4 & am constantly getting all sorts of errors. I see the Blue screen way too often, & my programs are always performing all sorts of illigal operations. My system temp is usually around 60C when I restart my pc in the boot menu. I have two questions. First, why can't I get my temp below 60C. I have tried at least three different hs/f's. And second, what could be causing my problems? Is it the overheating? I have tried changing everything besides the cpu, mobo & ram. Which is these is most likely causing the problems?

Check the contact with the core. And, did you use thermal paste? If not, get some on ASAP. Also, whtat mobo do you have?
About the topic, I have a Gigabyte board, and their themisisor is bendable, so you can bend it to be closer to the Proc. Bottom, or further. i currently have it touching the bottom of the core..

SPECK: Might also be RAM or power supply.

Speck102,
A very simple way to rule out a heat issue, is to open the side of the case, and place a small house fan blowing on the mobo and components. If you pc works, then heat is your problem. It's probably being trapped inside the case without proper means of exhaust.

I think it could be a heat issue. I am currently running with the side of the case open, and I noticed that it has a bunch more probs when it's hot in my house. I probably need to add more cooling to my case. I do have thermal paste, but the temp still seems a bit high for my liking. Even when it's cold inside it still runs around 58-59C. Maybe it is the thermal diode thing. I have an Epox 8k7a+.

The inside of my case is always around 80F (of course, I am upstairs, and my room gets up to 90F I think (sometimes). My parents refuse to turn the airconditioner higher (the basement is freezing). What do I say? PUT ME IN THE BASEMENT.. (I have 2 92mm intake, and 2 92mm outtake. All on fanbus).
Oh well, never gonna happen.
