Dear all,
Really thanx for the replies! Just another question, where can I buy those specific electric stuff?? 'cos I don't think the DT stall in my school has such thing... Also is it my so-call 'idea' really crap? (yes I know it is, but my DT teacher said yes when I told him this idea... :evil: ) And here is the whole thing, I gonna make the sensor next to the comp somewhere, then connect to a LED and a buzzer, should I connect to a comp fan too, so that it blows when it becomes overheat? Thanks for reading. ^^
well, as someone already mentioned, pretty much all newer motherboards (probably anything 2 years or newer, and most before that), have built in temperature sensors. HOWEVER, alot of computer manufactors like emachines, Dell, HP, Gateway, etc... probably don't have temperature sensors on there motherboards (depending on the particular model of course). Any motherboard you buy for a computer yourself will have at least two temperature sensors, one for the processor, and one for the case in general, and in the BIOS options there will be a place to make it shut down your computer at a certain tempurature, go into standby, etc... There are also many tempurature monitoring programs out there that take advantage of these motherboard sensors such as Motherboard Monitor (google it).
that aside, have it send off a warning around 65C-70C (notice that's celsius), anything over that, and it get's critical for most AMD processors. Pentiums run alot cooler, but i'm sure there temperature range is around the same general area. That's what'd I personally recommend in any case.
Now, as for places to purchase these types of electrical components, assuming you are in the United States, i recommend the following:
www.jameco.com
www.digikey.com
and
www.mouser.com
in that order. I've never used the last one personally, but I know alot of people who swear by them.
...and for your last question, you can add a fan if you want too, or make the computer go into standby or something.. shouldn't just let it fry.
