--- Comment #4 from Mark Millard <[email protected]> --- (In reply to gmbroome from comment #3) Do not interpret my notes as an attempt to block the changes. The notes are just general background. Keeping a failure-mode machine operational can be worth while in the right kind of context. I just did not want the performance tradeoff and I did not want to ask Justin Hibbits to do more than he already had done. I have access to an example "quad core Powermac G5" of each type relative to one pump vs. two, where both work without overheating problems and always have: # sysctl -a | grep pump dev.smu.0.fans.cpu_a_pump.rpm: 1716 dev.smu.0.fans.cpu_a_pump.maxrpm: 3600 dev.smu.0.fans.cpu_a_pump.minrpm: 1250 (So only one pump.) $ sysctl -a | grep pump dev.smu.0.fans.cpu_b_pump.rpm: 1485 dev.smu.0.fans.cpu_b_pump.maxrpm: 3600 dev.smu.0.fans.cpu_b_pump.minrpm: 1250 dev.smu.0.fans.cpu_a_pump.rpm: 1480 dev.smu.0.fans.cpu_a_pump.maxrpm: 3600 dev.smu.0.fans.cpu_a_pump.minrpm: 1250 (So two pumps.) I put the same kinds of loads on each, although one has 12 GBytes of RAM and the other has 16 GBytes. As far as I can tell if a PowerMac G5 Quad Core has an overheating problem then something is in a failure mode, usually the cooling system. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
