New CPU Waterblocl Idea

[joeswm8]

Instead of the traditional thick copper waterblock with a ton of pins, how about an extremely thin piece of silver to go over the CPU. a 30mm by 30mm by .5mm piece of silver soldered to surrounding copper which is what the housing goes on.

this yields basically immediate heat transfer to the water, like the water is touching the CPU, and thats the ultimate goal, right?

would this idea work?

Hiiii

I'm up for new things, try it on an old PC. It would be cool also to have an infared surface temp scanner in a PC.

Whats the worse that can happen.
Think about the worse, then the impossible. Then go for it.


Lol.

Not sure if there's enough surface area to remove heat as fast as the CPU produces heat under stress.

The ultimate goal is to remove heat as efficiently as possible.

you said it youself before, water heats up slower than copper. Well, the samething would apply here. The principal behind water cooling is to use the copper to quickly dissapate heat from the cpu and then use the water to take heat away from the copper. The copper has a bigger surface area for heat to be absorbed into. Its the same principal as using a piece of copper plate to tig weld on to create less distortion on the actual work piece or burning a hole through aluminum if thats what you're welding. Silver has about the same properties as copper but copper is a lot cheaper to work with. What you are talking about doing is really way too thin. As an experiment, take a piece of copper block(at least 1"^3) and a piece of copper sheeting 1"x1"x1/64"(about the same dimensions as your sheet of silver). Holding each one by your thumb and forefinger in each hand, place each one on the tip of a candle. Let us know what happens.

using radiotor fluid or something would have you way better off..

Not really, radiator coolant is a mixture of water and antifreeze. You should use some (or other corrosion preventing additive) in your water anyway. bldgengineer has it right, you want a big surface area for the liquid to be in contact with. All the liquid is doing is taking the place of air removing heat from the heatsink.

something like that might be better.

It gives a good area for the water/coolant to be in contact with the heatsinc, and should dissapate heat very good. Only thing is it is going to be difficult to make unless u start with a normal copper heatsinc, and then add the copper walls and the holes for the coolant tubes.

IMO it's pretty silly to make your own blocks now. There are many really good ones you can buy.

yeah but it is just for fun and for the experience. And hey, what if one of the designs you run into works really well, and is revolutionary? lol

Not too expensive and would be really fun over the summer. The tools are also handy for a variety of other things
