Whoops I made the mistake of checking out the picture of Princess Leia.

Sorry Pc hardware, I was unfaithful, but this has only made me stronger and never again will I make that mistake.

*hugs Pc*

is it just me or does anyone else think these Global electronics giants are a bit tight with prizes and prize money?

Oh my God: The bloke on page 2, bottom left hand picture - they way he's pouring out the LN2 - he's just ASKING to lose his hand!

I'm not some health and safety freak, but come on, show the stuff the respect it deserves!

Ive seen heston Blumenthal (the chef) flick it like water with his bare hands so as long as your quick its not that dangerous.

I'm not at alll a pro of exteme overclocking buta question came trought my mind:why instead of pot don't they use tubes so the LN2 is directly on the CPU?

Because as soon as you take the LN2 out of its storage container it starts to evaporate. So, a) its not pumpable and b) you need a vent for the nitrogen (now in its gaseous state) to escape.

Poor old england, I'm sure the same couple of problems happen at each event :(

Why were our guys using the wrong bios? Was the one they were using not sanctioned? Or did it just not allow the performance levels needed to be competitive?

There was a bit of confusion over BIOS versions. Normally moderators come round and check but this didn't happen apparently so they'd already done a few rounds in Super PI before the found out!

I've never used the stuff but I think it evaporates too quick to freeze your hand, you would have too dip your hand into it.

OK. But MSI provided the motherboards, CPUs, GPUs, PSUs, and HDDs, so why weren't all the boards loaded with the same bios before the competition started? What about OS configuration, and display drivers? Isn't everyone given the same basic setup? Is the team's ability to find the right bios, and drivers and install them correctly something they're judged on?:|

having used LN2 everyday for about 7 years I can say it burns if you leave your hand in ti for too long - but you can flick it or throw it at someones jeans quite safely! ...I've been stuck to the spot for fear of shattering my frozen trousers a number of times :-)

All the hardware is retail boxed so it stands as good a chance of arriving in good order but I guess it's easier and quicker to get each team to flash to the correct BIOS than one person doing this 15-20 times. But yes, it's unfortunate that this wasn't picked up on...

Are those capacitors normally like that? :?

It's modded?

It's called the Leidenfrost effect. What happens is that part of the LN2 evaporates into N2 gas as soon as it touches, so there is a always layer of gas between the liquid and your hand, so it won't freeze you unless you really try to.

I think he meant sealing an open ended tube to the CPUs integrated heatsink and pouring directly that way, so like a pot with out a bottom.

I wish some video could be taken at these events. pictures are nice but video would be cooler (pun intended) ^_^

There's a vid on the final page :D

Thanks for the info guys - I was obviously basing my shaky knowledge on urban myths & too many Hollywood films! The Leidenfrost effect was a good read.

Bit-tech, not just entertaining - it's educational too! :)

ooh lol my bad I thought it was another picture lol didnt catch the caption, okay let me correct wish there was a video that covered the event. not a small snippet like that. Like have one OCing session recorded from them setting up the gear to then tweaking the gear and what not.

@Lizard
Thank's but what I mean was: using a tube the same way you use the pot but since it has no bottom it be directly on the CPU, like HourBeforeDawn said.

A pot like that would be very a poor usage pot the problem is that some cpu's don't like -196c they just stop functioning with a pot with no mass at the bottom by putting ln2 in the pot it would drop way down to fast and have no load holding the pots with larger mass between the cpu are used in a different way the pot is cooled by the ln2 and the cpu is cooled by the pot but due to the large mass that is cold it stays colder longer which makes it light work :)

The pots with no mass are very hard to control but use little ln2 the larger pots like mine in the pics take more to get cold (1l for -100c) but stay colder longer say a 5c drop every 30's or so.

You could say there tuned to load the same as a single stage phase cooler would be.

Some pics of my pot build can be found here for anyone interested :)
