how unsafe is it to use to cool ya cpu for a fast bench mark? will it short my board?

[DF9sLGSU]

Well there are a lot of precautions. Umm, good thought. but you need to be well educated to even entertain the idea.

I think you should elaborate as to what you have and to why you want to.

"Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid oxygen. Further, if soaked in liquid oxygen, some materials such as coal briquettes, carbon black, etc., can detonate unpredictably from sources of ignition such as flames, sparks or impact from light blows. Petrochemicals often exhibit this behavior, including asphalt."

You tell me....

LN2 is the way to go.

yeah maybe iu beter scratch this plan sure dont wanna kill my cpu i was thinking a ocing my 8120 to around 7 k

Are you trying to justify your handle?

[Pharmadryg]

nah i was just talking pcs to a freind and super cooling came up and she said she can get some liqiud o2

[exchpaypalgold]

Extremely dangerous - make sure you use LOTS of video cameras to record it!

It's seriously nasty stuff! Stick to LN2!

[SNUfR8uI]

ty for the advice everyone looks like ill skip this plan

[goctorsurger]

Smart, if disappointing decision - even without reading this -

Haven't you heard? Oxygen is extremely flammable.

Uh, no it isn't - quite the opposite

Blind leading here...

Lots of fire on earth is oxidation with carbon-based material as the fuel and CO2 as the (one of the) products. Without oxygen there is no flame. Without fuel there is no flame.

[AngelinaTheElf]

I'm surprised at you Will.
You simply CANNOT 'burn' oxygen in air - you need a fuel - as the oxidant it is used but isn't of itself flammable by definition. That's why I said quite the opposite to being flammable in that it isn't the fuel.
The problem is that pure oxygen will allos some materials to spontaneously ignite and others which may not normally be flammable to burn fiercely.

Would it be safer than petrol to have in the kitchen, with the cooker on, and transfer into different containers? [chin]

I ask because I don't want to suffer the same fate as this woman: http://www.metro.co.uk/news/894722-f...rol-in-kitchen

Poor, stupid woman - I've some burn scarring and it wasn't a nice experience, she has my sympathy.
Petrol can be nasty stuff - people forget it's the fumes, not the liquid, that burns and those fumes can travel a LONG way and be quite easily ignited.

Regarding liquid oxygen, it depends, while the oxygen that gassifies won't can't burn, if it came into contact with a pilot light or gas heating the oven, then it may cause it to burn a little more fiercely - or even cause it to go so lean it extinguishes, I suppose, like with an oxy-acytelene flame when too much oxygen is introduced to it - never tried it with a pilot light, or know of it being tried.
If there is an oily rag, spilled chemicals, or such materials that the oxygen comes into contact with, they may self ignite in the oxygen rich atmosphere.

Probably the most well known disaster due to an oxygen rich environment is the Apollo 1 (AKA some other program I can't recall ATM) test fire that killed three astonauts. At the time they had a pure oxygen environment in the capsule - in space, the NASA vehicles used a low pressure, pure oxygen atmosphere in their crafts to reduce the pressure differential to space vacuum and maintain the partial oxygen ratio found on Earth.
It's believed that an electrical short caused a strip of velcro (which is relatively non-flammable in normal atmosphere) to burn fiercely, this ignited most of the other materials in the capsule which also burned fiercely, burning the poor sods alive - some other design errors also contributed and sparked a major delay and redesign of the whole thing.

This.

In the world of scuba diving, regulators that contain titanium are only rated for 40% O2 content for this very reason. Titanium has been known to react with high oxygen gasses.

Interesting... I guess my wife isn't the only one to react from high gas contents! [stupid]

Women hate when you laugh at their farts, I hope you have a dog she can blame it on.

im sure glad i asked wanna here something crazy we have folks down here who use it to help them breath and they smoke while doing it i assume thats whats in them green tanks you see them with
