I've seen many people using cardboard under the base of their motherboard, and i'm wondering, isn't cardboard a fire hazard?

The thing is, most people leave their rigs on 24/7 and go to sleep at night, yet i haven't heard of a single report of a house burning down in flames.

Paper catches fire ~451F

Those cards don't go above ~250F or they will auto-shutoff.

Cardboard I believe to be more durable to heat.

i'm more worried about small pins on the back of motherboards. They don't use much energy, but they get very hot.

cardboard would require almost a direct flame to catch fire. A GPU or mining rig would not produce near enough heat.

Cardboard I believe to be more durable to heat.

The 451F thing is largely popular opinion based on the book "Farenheit 451" but realistically different kinds of paper will have different autoignition temperatures depending on their thickness, coatings, impurities, cotton/wood ratios, etc.

Here's the real way to find out:


Yeah that's way more complicated than pulling 451F out of your ass, but suffice it to say the resulting number IS somewhat higher than the 105C (221F) most cards shut off at.

As for the solder, yes some varieties melt at temperatures as low as 90C but those varieties would never be used for computer parts. More likely would be solders in the higher end of the temperature range - some solder doesn't melt until 450C - so I wouldn't worry too much about that.

I was trying to show that cardboard theoretically would be more heat resistant than paper.

+1 I agree completely, I have been running several months using a small piece of cardboard to life one of my cards up and never had any problems and the cardboard piece is not hot.

Maybe their mine caved in?

Talk about waste!  Turn off your mining rigs until September!

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'
