What is a dangerous tempature for a P4?

I have been reading the boards and have not seen a good breakdown on what tempatures begin to become dangerous to a CPU. Everyone agrees that 65C and above is bad news.. and 40C is fine. But what about in between? Is 50C ok? 55C?

I have a 2.8c and I can clock it to 3.2GHz but it hits 57C with Prim95 in full heat test mode, and drops to 25C at idle. For now I am dropping it back to normal, but would like to know.. whats a safe speed to boost it to? (Room temp is about 18C)

Pentagram4 CPUs are good to go till... well I don't think you have to worry about that. The midi-chlorians within these things are smart enough to know how to feel heat you see. So, after much heavy operations, with the core heating up by so much, it will "throttle" the speed back down.

The midi-chlorians sortof eat each other when it's too hot, then there's not so many of them to produce enough heat (they're constantly mating, so they're always hot).

If your temperatures doubles to 100%, then you're all good, cuz then you have healthy & supple midi-chlorians, good for constant mating.

Reflect on the past.
But focus on the present you mofo.

Increase but as much as 10%

2800 * .10 = 280
2800 + 280 = 3080 Mhz

So that it won't go very hot.

Try also a much better HSF solution.

I think 50C is bad for a long period of time.
Just stay below 50C ASAP.

If the computer lasts three years, thats plenty. Dying in 3 months, thats more what I am worried about. Yes, it's the stock heatsink.. I plan to get something better.

Not sure what the S spec number is. It's a Northwood P4 2.80C. CPU-Z reports F,2,9,0,0,D1.

How can you tell if the CPU enables the thermal protection? I don't plan on running it anywhere near 72C, but do wonder how and if it can be detected.

Thanks!
