Fear of overheating

[leichaolan]

Hello all. Just a curious/paranoid question for you guys. I'm sure all of you usually just leave your pc on for the day rather than turning it off and on and off an on. Usually, this means turning it on in the morning and off at night. Therefore, any excursions (work/play) that you take, your pc will be unattended. What happens if the power supply and/or cpu fan both go out when you are not home? Would there be some sort of safety that would shut off said devices or would they continue functioning until they fry themselves?

some mobo bios you can set the temp to shutdown, look at your motherboard manual and see if it supports it.

Also if you find your bios does not support shutdown on over heat or fan failure
You can install on of the system monitoring program .

I use Mother board Monitor (MBM5)with my systems that run 24/7.
it monitors both temperatures and fans.
if the temps get to high or a fan speeds drops below a preset speed.
It sounds an alarm and then runs a shutdown program .

Almost all newer motherboards sense the CPU fan speed and will shutdown if 0 RPMs is sensed and will not boot until there is a working CPU fan plugged into the CPU fan header (unless you have the CPU HSF plugged in elsewhere and another fan like the north bridge HSF plugged into the CPU fan header never do this). If the fan is too large and/or too fast and burns out the CPU fan header the system will shut down and will not reboot until the motherboard is replaced unless it just burned out the fan power and not the sensor if this is the case you may be able to use a fan that uses the sensor wire to the CPU fan header and is powered by a 4 pin molex from the PSU. I use this settup on both my systems to keep from burning out the CPU fan header. My Athlon system has a Thermoengine with a Delta 60X60X38 8000RPM HSF and my P4 system has a Alpha PAL8942 with a Delta 80X80X38 5700RPM HSF. The only fans that I have that are powered by a MB fan header are the northbridge HSF and the AGP GPU HSF. If the PSU quits the system will shutdown and stay shutdown until it's replaced no power=no damage.
