Vaccum cooling

Don't seal it too tight... Unless you're trying to reduce the air temp by creating a true vacuum (could be dangerous unless you modify the case to compensate for the stresses involved).

Plus, a high pwered vac will create a lot more noise than any other cooling system out there. Unless you position the vac inside a sound proof room/box you'll have to deal with the excessive noise.

If you're just looking for ultra efficient, or sick cooling, look at either liquid cooling with radiators out the whazoo and blocks on every heat source. OR invest in a VapoChill rig...
 
Why not just flip every fan in your case to exhaust? I would imagine that would be the cheapest solution...
 
why not move to canada or alaska get two zalman reservators stick them together throw em out in the snow get a stronger pump for the extra tube length add alotta anti freeze to your water and run your comp at -20° C for next to nothing?

LMAO!!!!!
 
Next to nothing? Haha good idea.

How about take off a side panel to your comp and use a 12" desktop fan pointed at an angle so there is room for exhaust. Then put the whole setup in a fridge, move to Alaska, and live in a teepee.
 
The idea of the vacuum really makes no sense. Even if there is no air in the case from the vacuum the components will still hold heat; that is if they survive a vacuum at all. While it will still dissipate as radiant energy there will be no air movement to cool heatsinks. Just won't work. If you had an intake and you were pulling hot air out then yes that would work but that would be a waste of time since case fans do this already.

This really is a worthless idea, sorry.
 
vacuum eh? so wheres the heat gonna go?.....if u had a true vacuum, well u need a pretty sturdy case, and then the wholthing bout air cooling is that the air molecules take the heat away from heatsinks via convection, with no air your components are just goin to stew in their own heat as theres nothing to take the heat away....heat will leave by being radiated as IR but, on the whole air is better
 
I suppose the vacuum could work better if you installed some channels in the case for the airflow to follow from an open vent over heat generating components, but suction will only work the best along the shortest pathway.

As well as magnetic cooling there's also laser cooling, which is nice.

Leave it to T'rock to chime in with a little quip. LMAO as well. The move alone would cost more than an army of phase changers.

omg talk about cool.. forget the vaccum lets go to canada
 
How about going with true Arctic cooling and move to the Arctic Circle?? Leave a window open in the room with the computer on it and you'll have one chillin system. Of course, you'll probably need to warm it up just to power it on, but it'll be frosty...
 
Since semiconductors perform better the colder they are, you could probably get your rig to fly if you just left it in a freezer.

Problem is, when other parts get below a certain temp, they either perform worse, or not at all. That's why most computer parts list operating temps above 40F... Also, when below a temp range, electricity tends to perform worse.

For example, at my sister's house, during the summer/warmer months (above 45-50F during the day) they can run just about anything they want in the garage (detached, with a 20AMP breaker). During the winter months, if you turn on anything but the lights (such as the compressor that peaks at about 12AMP draw) it trips the breaker. The same power draw is going on, just the line isn't buried deep enough to protect it from the cold and so the power can't get through it to feed the items on it.

I'd hate to see someone try to run a normal household electic item in sub-freezing temps... Chances are it either won't run at all, or will run poorly and not for long.
 
i am socstealer yet i had to change user name so my idea was to use a high powered vaccum yet the noise and how to seal a case was the hard part of it, yet the idea is not sound consider phase change is a cheaper option if you can believe it

I hear ya there. Honestly, if you could somehow manage to pull a perfect vacuum inside of a case, your components would fry. There would be nothing inside to transfer the heat (like...air for instance) and your CPU would just sit there and cook.

Dude, the problem isn't that the line is cold...LOL It's the oil in the compressor that's cold and thick which in turn requires more power to turn the compressor, which means higher amp draw to the motor, which causes the breaker to trip. I guess that the reason your car is hard to start when it's cold out is because the wires are cold... :roll:
