OK...so I work as an IT Technician for a medium sized manufacturing company. We have a PC that's sole job is to collect data from an Access database, and upload it to an AS/400. Well, as I was sitting here earlier tonight, I got to experience what would happen, if your processor starts to REALLY REALLY overheat. My first clue was that it sounded like someone shot a small gun a few feet from me. This was the sound of a capacitor getting pissed off about the over adundance of heat, and finally deciding that he didn't want to play anymore. I can now tell you from experience that capacitors are LOUD when they decide to blow up. So, obviously, I'm thinking "WTF?!", so I run over, pop the side of the case off, and am met with a nice cloud of smoke. This smoke would be caused by plastic where the processor plugs in that was now beginning to melt/burn. Quite the interesting night. There was really no point in this post, except to warn you to keep your CPU cool. More can happen than just disrupting PC performance....which is something I always heard, but never really paid much attention to until tonight.

Me and a m8 of mine made a new system out of spare parts, we added a Quantum 10Gig hd, and after a a wrking load of about an hour, we smelled something... Opened the case and there was this little orange flame coming out of underneath hd (circuit board). I havent seen a hard disk be removed as fast from a pc in my life.

Be warned ppl have adequate cooling...Scary stuff:

i think my comp might blow up...its moist and hot in my room plus my comps been on for hours...

cool!

one word comes to mind...."FANS"

Use them...i have 1 comp with 6 fans and the other with 7

I haven't cleaned out my tower in years. Sometimes my computer makes wailing noises like a dying giraffe. It's probably so full of dust it's just choking on all of it.

I should probably open it up and check it out?

might be your cpu fan losing its center of balance or something... had that happen to my computer, it sounded like a fucking small airplane... took the fan apart and put some WD-40 in it.... worked like a charm for 2 months, now it's starting to roar occasionally


and i so need a new pc.

your a bit muddy on the terminology, in your post. FIrst you say cpu then you say a capacitor blew, I can tell you these are both mutually exclusive. The processor has no capacitors on it. The circuit boards (motherboard, perhiperal cards etc.) do have them but usually when a cap blows it isn't from overheating it's just a bad cap (been leaking or whatever) or experienced a voltage spike. In that case the PSU would be the culprit. MOst modern CPU's have a thermal protection circuit built in them to prevent a mini-cherynobl like meltdown inside your case.

P4s use clockspeed ramping and a IHS. Both safety features can be disabled (if your a nut.. i mean overclocker) for the sake of teetering on the edge of disaster performance. it takes a bit of handiwork to remove the Integrated Heat Spreader so most people never do that. In any event when the thermal probe built into the CPU die detects abnormally high temperatures a thing called a clock throttle kicks in and basically limits the processors clock speed (thus slowing down electricity to heat conversion significantly). That being said you can take the heatsink off a p4 WHILE ITS OPERATING, and the machine won't hard crash (although expect a myraid of errors, it takes more than 10-20 mhz to keep a modern system running stable). I'm not sure about newer amd processors with on-die thermal probes but the older models would literally melt if you took the heatsink off (as in the die would melt). Interesting stuff :-)

you can look for an old toms hardware article which effectively demonstrates both these points (it was a slow month i guess)...

I recomend the Enermax 12 bay server case, it has space for seven cooling fans

Well, yes...I did relate the CPU and the capacitor, because on this particular Slot 1 motherboard, the CPU sits directly next to 5 capacitors. When the capacitor blew, I immediately killed power to the system, and since the fiber stuff (I have no idea what that is called. LoL) that was inside the capacitor was now all over the CPU and surrounding parts, I started dismantling the system. When I realized that the CPU was actually so hot that I could not stand to touch it long enought to pull it out of the board, that is when I accounted the blown capacitor to the over abundance of heat. Regardless of what caused the capacitor to blow, the motherboard is now pretty much ruined (barring any of our other guys trying to solder a new capacitor in its place). I doubt we will be using this CPU (PIII 600) anymore, either....

Even idle and with the case side off my CPU temperature is currently 53°C! I believe that generally your processor is safe up to 70°C, but the warmer it runs the shorter its lifespan.

You can use an app called 'Motherboard Monitor 5' to observe your temperatures in Windows and set high-temperature alarms. Ideally though your computer should be capable of turning itself off automatically should things get dangerously toasty.
