Linus needs to read this !!

nope , its on the gpu itself , or are you talking gpu bios? im shure they have a hadware shutoff tho , non software/bios

The firmware controlling the card is what tells it to shut off. I'm pretty sure it's impossible for the silicon itself to detect the temperature.

So if you do manage to make a custom bios for it, how will you address the melting point of the solder?  Convincing a board to stay functioning long enough to reach the flash of any of the components is mostly a pipe dream.

Set temp limit to 40000000 and set the voltage to 5? You'd fry the motherboard and PSU but still

Anyway, I think that's a terrible idea for a video. It's not a review, not a guide, not informative, not helpful in any way, not even particularly entertaining. Just destructive.

I'm sure that if you dig long enough, you'd find videos that:

1) Don't go in any of mentioned categories

2) Are even more useless than the idea at hand
 

For instance:

The chances are that the silicon will simply stop working long before anything catches fire or does anything more interesting than give off some smoke.

 

More interesting may be to get an old Pentium 2/3 machine, get it running under high load with some older games, and over-volt the 5v rail slowly and see what pops first.

Yeah surely the gpu would just die before it caught fire

[samcool55]

It would just die, couple of things to keep in mind.

 

You need more than heat, with just pure heat it would very likely melt and that's it.

Also if something shorts out and is a potential firestarter, the PSU would just flip into protection and nothing would happen.

 

In the ideal case you have a overheating gpu, powered by a cheap-ass psu and the gpu causes a short and the PSU explodes.

Which is also stupidly dangerous and in the worst case, you die.

 

Sounds good, but it's stupidly dangerous and not a good idea.

 

It's like mythbusters, if you want a bang, you have to get rid of all the safety measures which is stupid because if you do that and aren't careful, you might die.

I'm not sure if GPUs actually implement it, but it is entirely feasible to detect the temperature in silicon and, in fact, it wouldn't be very hard to do at all. Instead of the sensor data going straight to some MCU or whatever the firmware is run on, it would go to a dedicated circuit whose entire job it is to take that value and see if it's above a threshold. It would add the overhead of essentially one comparator and some extra control logic to deal with the comparator signaling that things are too hot, which in the scale of the entire GPU, is almost entirely negligible.

 

It may just be that the firmware threshold is typically set to be below this hardware threshold. Doesn't mean there is or isn't one, though.

It's locked on a hardware level.

I just had an amazing idea for a video, what if you could remove the temp limit of a video card and run if maxed out without cooling to see if it could set on fire. That would be the coolest video ever. Maybe like an older card would be able to do this. Please can we try get this idea through to Linus. 

lol well, he does have that GTX 480... /s

 

But actually, that's not how it works... fire needs fuel, heat, and air.  The "fuel" part would be missing in this case since metal does not burn (well, not at those temperatures/in those conditions)

[theadult]

Now that does sound good. If anyone can destroy hardware it's our man Linus.

You know, the sad thing is that the last two were some of my favorite LMG videos.
