If the cpu heats up, it will take a while for the clock crystal to heat up and will not heat up as much. Ie, the cpu could jump to 70C briefly while some calculation was being done, while the clock crystal heated up almost nothing. It is probably better than nothing but if the computer has a very variable useage, so the temp fluctuates a lot, this will be much noisier than directly measuring the temp of the crystal. If the computer is pretty stable, it should be fine to use other proxies. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
