Here it's probably a variation of at least 10C. The computer CPU use itself is fairly constant throughout the day, so it may well track ambient temperature: http://www.satsignal.eu/mrtg/performance_feenix.php Another PC in the same room running a FreeBSD system has about half the jitter, but far less offset - PC Pixie at the top: http://www.satsignal.eu/mrtg/performance_ntp.php I recall trying some of the motherboard temperature monitoring software, but probably not for that PC. I'll look again. David _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
