If you CPU was very cool during operation

[Drastik]

due to system cooling, wouldnt it have the same negative effect if it was very hot and at like 90c?

 

[linkin]

Only if the temperature is so cold that the chip could no longer funciton.
Something like -30C is the coldest temperature that the chips will function at.

 

[StrangleHold]

I dont think so!

AMD's product manager Brent Barry was noted saying that liquid nitrogen and liquid helium are best suited for high-overclocking environments, the former bringing the temperature down to about -140 degrees and the latter to around -240 degrees.

maybe that just means the liquids were at that temperature but the processor, though quite cold, was much warmer due to operation.

Makes sense. Temperature may read that cold, but processor internals may still be functioning and giving off enough heat to keep a-workin'.

No, liquid helium and nitrogen are at -270C and -196C, respectively.

Both are correct, Yeti, those are the temperatures that the liquids are at, but stanglehold is correct in the fact the cpu can only get so cold due to it operating and creating heat itself.

No, the amd phenom II Line of chips do not coldbug, which means you could run them daily at -270c and they wouldnt mind it. For the phenom II's colder is better. For the Phenom I and intel cpu's though, they coldbug if they get too cold and wont boot.

The processor will stay around -240 to -230 while running under lhe, and around -150 to -160c while under ln2.

I never said Stranglehold was wrong. I was replying to konsole as he said that the temperatures that Strangehold cited might be for the liquid cryogens. Also, it isn't really correct to say that the CPU can only get so cold due to it operating and creating heat itself. The heat is there whether it is being cooled by superfluid helium or open air natural convection.

True, but even then the cpu will never be as cold as the lhe is, as can be proved by the current lowest temperatures acheived on both lhe and ln2 with the phenom II cpu's.

 

[Yeti]

True, but even then the cpu will never be as cold as the lhe is, as can be proved by the current lowest temperatures acheived on both lhe and ln2 with the phenom II cpu's.

Again, I never said that it would get that cold. Obviously with a passive phase change coolant you can only get as close to the boiling point temperature as the thermal resistance allows. In the case of cryogens, the resistance is greatly increased by film boiling.
