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.
Hope for the future.
Reflect on the past.
But focus on the present you mofo.
Since you haven't given the S spec number of your cpu I can't give you the exact thermal specification for your cpu.
The lowest thermal specification for a P4 2.8C is 72C. This rating is the highest possible core temperature where reliable operation is guaranteed. If you go above 72C the cpu's thermal protection may begin to lower internal clock speed to reduce the core temperature.
Depending on your S spec number the thermal specification for your cpu could be 72C, 73C or 75C.
Don't worry if you overheat your P4. They have built in protection to prevent internal destruction. Running your P4 for extended periods of time at high temperatures +60C may shorten the life of the cpu and other components. But do you think you will be using this system five or more years from now?
