Alternative to Shutdown devices?
 

I was messing around in my BIOS (Epox 8k7a) and noticed that on the PC Health Monitor (or whatever it's called) there is an option to auto-shutdown if the temperature hits a certain point. There are several temperatures you can chose - do you think this would be more reliable than a software shutdown? At least it seems as though it would be quite reliable.

Thanks for your input! :D

naw, dude, ANY type of software shutdown wouldnt be as reliable as a hardware method. Im currently building a device that will cut the power to the pus, or surge strip, it depends how you set it up, and im going to build somethign that will shut down your system, or tunr on a second pump if the flow in the watercooling system suddenly stops.

The system here on ProCooling in the articles section is pretty good! I though MotherBoard Manager 5 and ShutDownNow would be a safe solution until I tested it. My system never hits 50c anymore, so I set the program to shutdown immediately at 50. If I kill the fan the temperature rises slow enough that it works fine. If I kill the pump however the system doesn't even register 45c on MBM5 before it locks (and heat continues to rise). I know my system is stable to over 60c so obviously the temps must rise fast and high.

Definetly get some sort of hardware shutdown!!! I do however run my voltage and mhz quite high so possibly in a slower system it would be able to shutdown before locking, but I'd rather not chance it!

P.S. when the system freezes those BIOS shutdowns don't work either, so a stand alone hardware device is the only way to go!!!

Yes the bios shutdown would be better than a software shutdown IMO, IF the min shutdown temp you can set is low enough. The problem with bios and softshut down is if the PC locks up before it gets there. In a water cooled system without peltiers, and the correct shutdown temp It should work fine on pump death, (mine does), as the water in the block won't heat up that quickly on no flow.

As said a dedicated hardware power off will work better but only if it is set-up right. It would need to monitor low or zero pump flow, have a low water level detector, and a separate CPU temp monitoring function to be a complete solution.
