Beware: Asus A7N8X-X is a fire hazard

Hi,
I'm a user of an Asus A7N8X-X.

A couple days ago, I almost lost my house because this motherboard does
not have a simple temperature monitor.

Imagine this situation: you left your computer running at home while
you
go to work. But, your cpu fan stop wroking, you Athlon XP CPU goes to
100Celcius and your wooden furniture start to burn.

You come back from work and find your home in ashes.

I got lucky, I could shutdown the computer while the CPU was at
80Celcius.

As a longtime (8years) Asus fan, I have buyed many Asus mobos, but I
can
not understand why they can not put a temperature monitor in their
flagship
Nforce2 chipset mobos.

Anyways, if you think to buy this or another mobo, check if it would
stop
your house from burning.

Regards, a hardcore Asus fan.

My mates Asus P4P800 E Deluxe fried his P4 cpu recently and it was agreed at
his supplier the mobo was faulty.......is this why it didnt shut it down...I
didnt even know there was no temp sensor
 
You are an idiot. Do you really believe that the cpu will burst into flames?
Get yourself a calculator instead, its more your speed.
 
You must have skipped a lot of important stuff in school.
100 C is the temperature where water boils. It's not even
close to the temperature where wood burns. Around 450 F
is where woods begins to burn. That's 232 C. Take a trip
back to grade school. My 3rd-grader knows this much.

Huh! 100c is a safe temperature with respect to fire hazard. There is
nothing in the machine or probably in the room or house that would
combust at 100c - that only the boiling point of water!

Most electronic components will survive that temperature. Even if they
don't, the glass fibre multi layer board will not even change colour
let alone set your wooden furniture to burn.

Think about it - solids or liquids do not burn as such, they must
reach a temperature high enough for them to convert their molecules in
to a flammable gas. Then you must have a source of ignition whose heat
must meet or exceed the flash point of the flammable gas.... I know of
nothing in the domestic environment that has a flash point as low as
100c

Apart from anything else, your subject line opens you up to
litigation by making a definitive statement like that. Especially on a
sampling of one unit!

May I suggest a more cautious approach in alerting folk to a
'possible' problem that may cause a smell of something getting hot...

If you check this link:
http://mbm.livewiredev.com/comp/asus.html

the A7N8X-X has eight pin Winbond chip W83L785TS_S
near the processor socket. The chip is next to the upper end
of the two DIMM sockets. That chip is an overtemperature
detector, and it senses the diode temperature of the processor.

(The file name is wrong, but the file is actually for the W83...)
http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W86L785TS-S.pdf

On page 10 of the datasheet, you can see the chip is programmable
by resistors, and is intended to trip somewhere around 85 to 90C
of diode temperature.

If the diode in your processor is bad (open circuit), this controller
can fail, but Asus was not negligent - they did waste good money on
an overtemperature detector (a.k.a Asus C.O.P - see feature set
in your manual).

you are more dangerous to your house than that system will ever be

Classic title for a science fiction novel. Fahrenheit 451. The temperature
at which paper burns (basically wood)...
Worth also being aware, that if a component reaches a temperature, the
stuff round it will be cooler. The element in a toaster, runs at perhaps
600C, yet it doesn't set fire to the toaster, or the kitchen worktop.
As you say, a trip back to school is definately called for.
Worth also saying, that dependant on the processor, the peak manufacturers
'working' temperature, may well be well over 90C, so the 80C seen, is not
even exceeding this.

Best Wishes

Have you worked for Gigabyte for very long?

Oh no! So what happens at Fahrenheit 911??? What bursts into flames
then???


Sorry, was really trying to pass up this troll post, but the opportunity
was just too good...

The problem is your case is not adequate, you need one that can take the
heat like this one:

Ok, Ok, no need to flame.
Maybe I over reacted, but my point is that the C.O.P. feature
should be a default feature in mobos of hi quality like the Asus ones.

Thanks for the usefull links,

What are you talking about? That board has this feature!

You said the CPU temperature reached only 80 degrees, that is below the
85 degrees max die temperature of the Athlon XP specs I checked..
 
Hi Robert,
many thanks.
You're right. I could not find the C.O.P. feature in the BIOS so I
asume it didn't have.

So, this mobo does not support changing the C.O.P. settings? I think
the 85 celcius should be the temperature when the C.O.P. feature
shutdown the PC.
Thanks for the info.

Regards,
Oliver
