uhm.. check TTIC heatsinks in "on the testbench" forum
those have a heatpipe in the center!

Didn't think of that, might be a good idea.

I heard once, that there was already made some kind of heatsink, with in the base, little channels. Their they put some kind of liquid, which had a low boiling point, and when the sink was "on temperature" some kind of faster heat stranfer started...

So there's coming air into the circuit, pump becomes louder.

I have no pussy hence no litter box.

Almost as new But, hey, you don't need a cat to go with it... Just take a cat's litter box, some used cat food cans to create the illusion you've got one, and here ya go, nobody's gonna look at it

I'm sure the docs will remain "unharmed"..

From liquid to vapor; well I will do more research on it.
Theoretically yes. but due to the boiling process, the air that's in the water comes together, and makes bubbles ? The water in Belgium does at least

So there's coming air into the circuit, pump becomes louder.

I would keep my most secret documents in a fish tank, let those thieves search the house

Reaction to "H2O" ...

Unintentional ...

There are important papers to be kept safe ....

We can always laugh at anything ..... not knowing we are being laughed at.

Btw, who's gonna put a book under water (exception made for schoolbooks, which are made to be destroyed asap )
Comment from Xploited Titan @ 2004/04/14
Indeed, but you can put your computer in it And it works...

M3 water destroys a book.
Comment from Xploited Titan @ 2004/04/14
Such products are 'common'... M3 has invented such stuff before... Problem is the price and the quantities in which you need to buy... And I think it's suited to cool your computer down, even though the liquid needs to be cooled too.

not if this is true:

Stunning, although it seems to have a boiling point of 49.2°C ?
Comment from Sidney @ 2004/04/14
The $30-40 cost is for fire protection cost base on square footage.

Where does the 49C boiling point show?
