      The article isn't very clear on what exactly caused the fire in the presario, though it does use "electrical system to malfunction" in the case of the monitor that burned down the business. Suffice it to say, this might not be an issue of ventilation. More likely, they were severe electrical problems in all cases. I would bet money that the cause of the Compaq Presario "bursting into flames" was the power supply, and not a poorly ventilated processor. When they overheat, things just tend to melt. No low-voltage IC should ever "burst into flames", even in a poorly ventilated case. In fact, the poorer the ventilation, the fewer the flames.

        And a properly-made power supply should never burst into flames. Normally, a power supply has a fuse in it that will blow to prevent the circuitry in the PSU from becoming overloaded. Sounds like there is a serious product liability issue with the PSU in the Presario in question.

          I might be willing to acknowledge that, though it really is well outside my area of expertise. On its face though, it does seem possible for a few hundred watts of power to ignite something. As long as the power supply maintains a nominal power consumption, the fuse won't blow.

        CPUs won't overheat anymore anyway; they cut their processing power until they reach an acceptable temperature. If they still can't cool down, there are failsafe mechanisms in place that shut down before any true damage can be done. Modern PCs won't even boot if they're too hot.

      The problem is almost exclusively the power supplies.

      Over the last few years, I had 5 power supplies fail, 2 of them with a giant bang. Heck, I'm sure that they would result in the place being burned to the ground if it wasn't for me pulling the cord out of the wall. The culprit in both cases was a cheap-ass power supply that came with the case of those $50 deals.

      Scenario one. The box (P3-450) was powered off. Was changing the network card though I noticed the power supply was suspiciously warm even though it was off. When I plugged the box back in (didn't had time to turn it on), caps popped in the PS with 3 large bangs and 12V rail became 120V AC rail. Yanked the cord out of the wall within about 2 seconds but the damage was done. Everything connected to 12V was fried. Sound gone. CD/HD fried (CD drive opened spontaneously like in those horror movies and the CD that was in it flew out, hit the wall and shattered!). The mobo/CPU/ram survived as only the 12V rail was affected. Later, I plugged in the PS on the workbench and within 2 seconds there was a fire inside the power supply. I didn't wait longer to see what would happen, but I can image that the place would burn down if that PS popped in the middle of the night.

      Scenario two. A different power supply. This was an old ATX power supply I was using for a different purpose - powering some equipment 5V equipment on stand-by power rail (yes, less power than it was rated for at that rail :). Was working fine for a long time. All voltages were fine. Then one day it just exploded in flames. Now, this PS was not in a PC at the time, so maybe not worthy of "burning the house down" scenario as it was only plugged in when someone was around.

      The last 3 cases are power supplies that died or were about to die. One of a Antec 300W PS - that one worked fine then just stopped working. Another was an HP propriatory PS - working fine then not. Died the Right Way. And the third one was an unnamed PS that just stopped giving right voltages. The 12V went down to 9V over one year and system stability was gone.

      So, at least 1 in 5 cases so far would result in "house burn down" scenario. Now, I do not keep any but the best PS boxes (Enermax) anywhere where a fire would destroy they house. The cheap ones are relegated to the concrete basement.

      There is NO OTHER component of any electronic device but the power supply that can destroy your house. And yes, a monitor also has a power supply, though a bit safer than the PC box.

      Of course, there is no 100% fire proof anything so the only way is to mitigate the problem, and also mitigate the energy waste problem at the same time. Unplug your devices when you are not using them. Unplug the TV/DVD/computer when you are not around. If you need the box up 24/7 (eg. server running your home phone system, bt, etc.), put that box in the basement on a concrete floor without flammables around it. For the rest, keep it unplugged when not using - surge protected works great here. This may save your house, and maybe $100+ in wasted "stand-by" power per year.

    • That doesn't matter much. I've seen systems go up in smoke and everything was perfectly in order from an approval standpoint. One was caused by one of the infamous electrolytic capacitors we had fun with a few years ago, and one was a manufacturing defect in a backplane that caused a slow short between a power layer and ground.

      I can see a simple solution: Develop a cable that either opens or shorts out hard when it gets too hot. String that next to some of the high power components and in the area where air
  • Well, although I would not expect an off-the-shelf PC to catch fire, I always felt strange about my self assembled PCs. Let's face it, there are components in my server which were never certified to work together. And this machine runs day and night.
    However, there is a simple solution: a small Cyprian company (FirePro http://www.firepro.info/products.php [firepro.info]) offers aerosol fire extinguishers. You can basically have a protection solution like it is used in data centers; --- but on a shoestring budget.

      The same could be said about your TV and DVD player. Really, you could say that about any electrical device and your house wireing. So, you should feel just as nervous about that off the self PC. To make matters worse, the plug in your house is generally going to be running with uncertified devices at 120v/20amps. The stuff you are plugging in together in your self built PC is certainly lower in both voltage and amps.

    Where's the UL [ul.com] while all this is going on? Or the NFPA [nfpa.org]?


    Its possible that these incidents are statistically insignificant given the number of products sold that don't explode. Or there would be new rules proposed in the codes to address these problems. These folks just live for writing new rules. In fact, there are some pretty strict rules covering electrical installations in hazardous locations like gas stations. Its just that no construction code can keep someone from running an extension cord and plugging in a PC around gas fumes.

    I've seen a desktop PC or two ignite - not just smoke, but a nice flamey burnout. The source of the problem in every one I've inspected was an electrolytic capacitor failure. Those components are under a lot of stress when they're used in switch-mode power circuits - such as the main power supply or the CPU voltage regulator.

    Fortunately, these fires self-extinguish very quickly when you disconnect the power - if your PC (or whatever random piece of tech) starts smoking / burning, pull the plug. These failures are only really dangerous in unattended machines - then this failure can and does result in a fire.

    Those little capacitors are relatively expensive, and manufacturers who are doing everything they can to shave costs discover they can replace the low-ESR computer grade electrolytics with cheap aluminum electrolytics - and then take it another step by sourcing the cheapest cheap caps they can buy. They manufactures know that this choice will result in a much shorter life for the equipment but those failures will occur after the warranty has expired so it's OK with them.

    Remember this next time you buy yet another power supply for your computer. It could have lasted 10 or more years, but the manufacturer saved a couple of bucks on the components so it died after a year or two. A fire caused by these cheap parts is actually fairly rare - less than one in a thousand machines (probably much less).

    The way to eliminate the majority of these fires? The manufacturers should spend the money it takes to use the right components - capacitors designed and rated for high temperature / switch-mode operation. That would also make power supplies last the life of the machine, slightly reduce power consumption, etc. But as long as consumers insist on the lowest price for products the manufactures will continue to give them what they are asking for.

    Imagine a shelf at the computer parts store: there's two different 400 watt PC power supplies for sale. One sells for $40 and the one next to it speaks of high quality parts and long lifetime and sells for $60. Which one do you think most consumers would buy?

      In 2001, 10% of the 100+ new Dell monitors burst into flames within the first two months. Because of very high ceilings, there were no real damage. And because we were a very big customer anyhow, they were falling over themselves to replace all the monitors, throw in plenty of extra equipment for free, and give us their bullshit form speech about how they take safety seriously, so there w

    • I see your point, but consumer electronics are not EVER supposed to catch fire. When's the last time you heard of someone's razor, blow dryer (1500 Watts and gets hot enough to glow inside) etc. catching fire when less than 5 years old (or ever for that matter). Price pressure is no excuse to create a situation potentially hazardous to life. If fire safety means the PS can't cost less than $60, then that's what it should cost.

      I imagine a few big dollar settlements will apply some correction to the problem

  • I had a several year old Dell 21" LCD monitor catch on fire. Luckily I was in the house and awake at the time, so I smelled the smell of burning plastic and found the monitor sizzling inside and emitting smoke.

    After unplugging it and setting it outside I called Dell support and after finally getting a real human to talk to told them my monitor caught fire. Apparently they were not paying attention because I was told I had to turn it on and run some diagnostics to make sure it wasn't my computer that was a
