Looks not bad, but I would checked it during good compilation, using all cores. Just to compare, my Core i7-870 with boxed cooler reports: 31C being idle with tuned power management, 53C being idle without any power management, 85C during `make -j16`. That system did `make -j16 universe` in about 3 hours AFAIR. PS: AFAIK dev.cpu.0.freq won't report you if frequency was lowered due to overheating. -- Alexander Motin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
