Guy running CPU @ 7.2 Ghz.....

Providing this isn't a total Photoshop job... Click me

How would he cool it? Liquid nitrogen? waters out for sure....

If by some freak accident it is true then remeber two things!

One: The candle that burns twice as bright only burns for half as long...
Two: That DDR 400 is still gonna bottle neck his system, makin that impressive speed nothin more than eye candy...... Though it is very tasty lookin eye candy.

Bah, total bottleneck, should have gotten those new DDR2800+ from I think it was Corsair

.

But impressive.

I dont think that this system get even beyond a system boot up screen. The guy is lucky enough that he got into the BIOS.

At tomshardeware they are often doing such things. Latest test i can remeber was overclocking intel CPUs to about 4-5GhZ. But 7+ GhZ sounds a little bit unrealistic if it comes to stability.

I still think its possible, the problem wouldn't be heat if the geek has liquid Nitro.

The problem would be SLOW responses from the rest of the system.

Tawian's overclockers are famous for crazy overclocking with liquid nitrogen, theres a few of them(Small group of ten or so) who apperntly snaged a supply from somewhere and rigged up a home made heat sink they can pour liquid nitrogen into

Last I heard they were still stuck at 6.3 though

A while back the good folks at the Screensavers poked around with overclocking with Liquid Nitrogen, but that was before the takeover

I suppose if you have buckets of money lying around you could grossly overlock your machine with a constant supply of the stuff, though I suspect you run the risk of burning out your processor over time. I don't honestly know the price of liquid nitrogen, but I seem to recall someone saying it was comparable to coffee.

Someone was running at 6 GHz with liquid nitrogen.

Bean, do you know any website can point us how to buy such heatsink, or at least provides instructions how to build ourselves? Anyone else could also help?

I'm seriously consider having such heatsink, especially if there's a model with the size of VSA-100 chip, so I could use them to *extremely* overclock my V5 5500.

Thanks.

Assuming you're referring to G4...

Such cooling systems are usually one-off jobs and not closed-cycle (someone literally pours in N2 at a rate faster than it evaporates). Also, it'd be a tad bit difficult to get it to work with a video card seeing as they're usually mounted the wrong way to easily work with it.

That'd be the one

What sort of serious OC'ing are you planning on doing? It'd think the cheapest way to do this would be to just refridgerate your box...

Well I see. Thanks, by the way. Anyway, is there any known liquid nitrogen-based, closed cycle cooling system? Or at least a web instruction to build one? Of course the sealing has to be VERY tight, I guess.

Drop the idea, liquid nitrogen is not something you want to screw around with. However if you make more money than you know what to do with (and don't want to give any of it to me

) then I suggest you hire a real engineer to build a system for you.

Praxis · Post by **Praxis** » 2005-02-16 11:45am

Yeah. Spill a drop of that stuff on your hand and you'll be whimpering for a week. And if the liquid cooling system fails for a second, the overclocked processor will burn a hole through the motherboard

Wrong spill a drop of liquid nitrogen on your hand and assuming it acutal touches your hand, your going to loose a good two inch chunk of flesh

Oh and it will hurt a hevlia lot

I once had a wart on the bottom of my foot. Doctor decided to burn it off with liquid nitrogen. "Oh, it won't hurt, the cold will numb your nerves instantly."

And that's why I don't trust doctors when it comes to pain. My only consolation was that I screamed so loud I probably scared the shit out of everyone else in his office.

Off topic, but is liquid nitrogen something aproved and used by medical staff??

He has a Ph.D and was/is (he may have retired by now) a practicing physician. It did get rid of the wart fairly effectively, and if I had to go through it again I'd actually probably be more comfortable with liquid nitrogen than with a scalpel - I'd just insist on local anesthetic this time. (At the time I was like seven years old, so I was hardly in a position to demand it... especially as I was still naive enough to trust those bastards.)

Depends on the size of the drop and how fast you get it off. They killed a wart on my hand with liquid nitrogen, hurt like heck.

The point, of course, is that you don't want to screw around with that sorta stuff.

Yep. I had the same wart burned off three times, by doctors in both Holland and the US.

They dip one of those things with the gauze on the end (what are they called?) in it, then push it on the wart. You hardly feel it on the wart, but some always invariably drips on the skin right around the wart and it burns like heck. And you feel a jolt of pain if anything touches the skin for weeks afterward.

A ten-second application of a tiny amount of liquid nitrogen is enough to leave your hand in pain for weeks. And thats on top of a wart, where the nerves are already mostly deadened.

I don't even want to imagine the effects on regular skin.
