Sorry Linus I don’t think you were specific enough! People need actual numbers or else the debate will continue to ad nauseum!

Mate, as both me and Linus mentioned (at 0:48), at higher temps – this is 105°C for most modern CPUs – the in-built temperature protection kicks in throttling the speed and dropping both the temperatures and the performance.

So it’s impossible to reach unsafe temperatures and nobody should ever worry?

Except about lowered performance with substandard cooling?

That’s right. If you aren’t into super-duper high voltage overclocking, there’s no way you’re going to damage your CPU due to heat. Even in that case, heat is primarily avoided as the main obstacle to reaching higher clocks.

For instance, I myself have ran my Core 2 Duo moderately overclocked at 95+C in GAMES probably for at least a year before discovering this (box cooler’s thermal paste turned to cement) and it’s still as good as new. Modern 32nm and smaller process CPUs are even more resilient.

You might say: “well, I would still feel more comfortable sticking to a lower temp threshold just in case”, but then remember that for the manufacturer who sets the Tjunction, it’s not just a matter of “comfortable”, it’s a matter of RMAing hundreds of thousands of broken CPUs if they don’t get their temperature margins right. That’s why I personally trust them with it.

heat tranfers through radiation in empty space, outer space near the earth is at 7 celcius, so your gpu would be well cooled, heat is also released through other mechanisms in space but im no scientist

+Juan P. Reynoso Well it may be 7c but… the solar rays on one side heat up to 180c and on the otherside getting no heat would go down to -150c but you are right by saying that there are other cooling mechanism and by having no environment to transfer heat, more % will exit into infrared rays

Heat transfer through radiation is rather inefficient though, so I doubt it would stay cool in space using standard equipment. Also space has a very high range of temperatures, some of which are definitely not good for hardware.

MrDeeb8 try to dial back your voltage slightly, it’s not terrible but you’re risking throttling if your temps spike, if you get throttled your overclock becomes basically pointless. Al about the sweet spot
