Heat = autoshutdown

Must make this short...

I just switched to water-cooling and realized something. If pump fails the CPU, Video Card, and mother board are instantly ruined. I can't find ANYWAY in the whole world to make the PC shut itself down incase the CPU or other components get to hot.

Don't they put auto0shutdown features IN the motherboards? I know some mobos come with this feature and it would be exactly the thing I need. I'm 2 days away from buying a Epox 8RDA+. Does this support auto-shutdown of some kind? I can't seem to find anything that says it does.

If it doesn't, can anyone recommend a ~$80 (shipped) mobo that will let me overlclock a lot?

Thanks

Most motherboards have BIOS settings to do that...My old Epox 8KHA did and it still fried an 1800+

I use Motherboard Monitor 5. You can download a program called Shut down Now! that can be incorporated with MBM5 to shut your system down when any sensor gets to a temperature, or fan slows down below a certain point, or voltages go high or low...wonderful app.

Install MBM5 and then go here: http://www.dworld.de/

I was trying to keep it hardware oriented. A program can always crash, or windows can freeze. I could forget to start the apps. Also, in the 3 seconds it takes an Athlon to burn up, i don't know if a software program could react fast enough.

If I can't find a mobo that will do it, taht will have to be my last resort. I will keep my fingers crossed.

it doesn't take an athlon 3 seconds to go from a normal temperature to die burnup. It takes it several minutes...I have mine set to shut down at 55°C...by the time it shuts down completely it won't be 60°C with water not moving over my waterblock.

Telexen: Is that a hardware shutdown like the mobo cutting power, or a software shutdown. Shutting windows doen takes about 30 seconds for me.

if its a pentium, it'll cut the processing power in half until it cools down and resume normal operation. My gigabyte board won't boot if its too hot and will turn off. Most new mobos and processors have protections against burning up.

Athlons don't have that like the P4 though.
There are aftercoolers you can get, and you could probably wire something to the power switch so that it will close it when the pump stops, but how would you detect it.
Telexen: If the water pump stops, then there is nothing removing the hot water from the waterblock. It will burn in a matter of seconds.
Joker: How do you find watercooling, is it quiet? I've been thinking about switching, but I don't know if it would be too loud to stand. my current setup is pretty noisy when going at full pelt.

Except for this HUGE problem of pump failure, water-cooling has been the coolest PC upgrade I have EVER made. I had 7 80mm fans in my computer, plus 2 HD's, plus 2 60mm fans on my video card that whine like crazy, AND a fan on the northbridge.

When I switched, I dcided to cool my CPU, Video card, and my northbridge all at one time. I have NO fans in ym computer right now except for the two whisper fans in the psu. I replaced the HD's with 1 big one and it is EXTREMELY quite. (thx Maxtor) I leave the pump running all the time even when the computer is off.

Can't hear it, really.

the CPU will NOT burn up in seconds if the pump is not running....I've turned mine on without plugging the pump in and it ran 5 minutes before the Diode got about 60c...the socket was still reading under 40c

just because water isn't moving doesn't mean it's not pulling heat away from the CPU. It's an all copper block...heat transfers through it well, and goes to the water...which doesn't just heat up in one spot - it spreads the heat.

I FINALLY FOUND SOMETHING THAT IS EXACTLY WHAT I NEED!

http://www.procooling.com/articles/h..._detector_.php

I had thought this was impossible. It's not! It's just INSANLY hard.

I read the article, but he doesn't explain it enough. I have no clue how to build something like this. Maybe I'll wait until school starts and see if my electronics teacher can build one.

I was SO close!
