Re: Monitoring CPU temperature: mbmon shows 201 degrees C
Just to summarize (after 5.5 days of uptime), i'd like to recap on what happened next. I burned the SiS 651 based motherboard, while memtesting, and i replaced it with a new Asrock, Intel 82865G based motherboard. All run fine, no panics, no unexpected segfaults. It seems that the old SiS was fine until i fitted the kodicom4400 on the PCI bus, when all the problems started. Now at idle i can get CPU temps as low as 35 deg Celsious, altho it turned out that was not my problem in the first place. Thank you all for your help.

I tried to monitor CPU temp with mbmon, which shows a very big value in COU temperature: I also opened the case in order to get ventilated with fresh air from the room. Actually, that doesn't work, your components will get hotter. This is because the case provides a through flow environment where air is forced to flow over most of the components most of the time. By opening the case you remove the force, and now have to rely on convection. What you want to do is make sure all the fans are running freely. Especially the processor fan. It may have stopped silently an dthat would definitely cause crashes. A fan at the front of the case blowing IN is more effective than one on the back blowing out, so if there isn't one on the front, add one. The 80 to 120mm ones can be very quiet and some can control their own speed if your motherboard cannot do it. If one can blow in the front and directly on the harddrives then that is a bonus, cool harddrives last longer. The basic idea of a case is to have air coming in the front and exiting at the rear. So make sure all your fans are blowing in the right direction. My office goes to 38C in summer, and all 5 computers just keep on going, using the principles above.

As others have said, I would recommend adding a rear out-take fan. Do not rely on the PSU's fan to take all the warm air out. The PSU generates heat on its own, and the fan may not be sufficient. A rear out-take fan should be located rather high - at CPU height - since warm air always goes up. This is where most cases have a place for the fan anyway. It is indeed as you say. The fans on my case are: the PSU fan, one takeout fan just below the PSU and the CPU fan. It is a medium tower size case. The thing is on the bottom PCI slot i have installed a Kodicom 4400 for video capture for use with zoneminder, (the FreeBSD port is available from the zoneminder site) and right above that a LML video capture card. and then while capturing 5 full frame-rate (25fps) cameras in zoneminder a) the load never falls below 0.4 even while no users use it (it is our family workstation as well:) b) all the heat from the kodicom flows higher to the CPU/memory area of the case Having said that, the issue with the temperature must not be my thing :( after kldload coretemp, i get [EMAIL PROTECTED] ~]% sysctl -a | grep tempera hw.acpi.thermal.tz0.temperature: 40,0C dev.cpu.0.temperature: -1 [EMAIL PROTECTED] ~]% The first always is stuck to 40 and dev.cpu.0.temperature to -1. This -1 probably means your CPU is not supported. The man page says Intel Core or newer CPUs, and as I understand this is specific to Intel and will not work on AMD. It works fine on my core2duo laptop. I don't know if it works with the earlier Intel CoreDuo (not core2duo) Assuming the heat is what is actually causing you the problems, your options are rather limited: Move to a bigger case with options for better ventilation (maybe 12cm fans in front / rear) or use fans with higher CFM ratings (that will also make it more noisy, one more factor to consider). I currently have a machine with a 25cm side fan. Completely noiseless, and always runs cool. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Achillea, have you told us what CPU you have? Manolis presumes you have an Intel, but I do not see this information anywhere in your posts. If you have a recent AMD, try the port k8temp. -- Tore ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I tried to monitor CPU temp with mbmon, which shows a very big value in COU temperature: I also opened the case in order to get ventilated with fresh air from the room. Actually, that doesn't work, your components will get hotter. This is because the case provides a through flow environment where air is forced to flow over most of the components most of the time. By opening the case you remove the force, and now have to rely on convection. What you want to do is make sure all the fans are running freely. Especially the processor fan. It may have stopped silently an dthat would definitely cause crashes. A fan at the front of the case blowing IN is more effective than one on the back blowing out, so if there isn't one on the front, add one. The 80 to 120mm ones can be very quiet and some can control their own speed if your motherboard cannot do it. If one can blow in the front and directly on the harddrives then that is a bonus, cool harddrives last longer. The basic idea of a case is to have air coming in the front and exiting at the rear. So make sure all your fans are blowing in the right direction. My office goes to 38C in summer, and all 5 computers just keep on going, using the principles above. I fitted a fan to the UPS as well (-: My box has 3 fans, one on the case blowing from outside=inside, one in the power supply and one on the CPU. In the evening, i will have the case/board inside blown/cleaned with air, i am gonna close the case, and i am gonna tune BIOS to fail-safe settings. When blowing the dust out, be sure to put the nozzle up against the edges of the cooling vanes on any coolers, especially the one for the CPU(s). Often such vanes are very close together and trap dust easily that will not be blown out when just cleaning the case and the motherboard. My portable, a Dell Inpsiron XPS, was running in a reduced-speed mode with COU temperatures in the high 70s C to low 80s C, but was also doing frequent emergency shutdowns at 89.5 C. After replacing two of the three fans and blowing out visible dust, the temperatures were reduced by about 15-18 C. Replacing the third fan brought the temperatures down another 2-3 C. Blowing the dust out of the cooling vanes brought them down another 6-8 C. Apart from that, i would like to have a reliable tool to monitor temperature. Is there anything in mind? As was suggested earlier, you should first post your CPU make and model. Scott Bennett, Comm.
