If I understand you were running a high overclock (CPU 1000 MHz, Core 500 MHz, SDRAM 600 MHz, 6 volts) when it crashed.
Obviously when busy with a high overclock the temperature rises.
When the temperature rises lots of physics change. Current may increase. Propagation delay may increase. Both these effects may affect overclock stability.
So, I don't think it's accurate to say the temperature reaching 70C results in a crash due to overheating.
You can say a borderline overclock setting may fail with increased temperature.
(when testing the temperature limiting overclock code, I deliberately tried to get the temperature as high as possible and got close to 80C.
for this specific Pi/power supply that was still stable, but with overclocking, your milage may vary).
