Cooling of Laptops - It it possible to use copper pipe and heat convection to achieve this??

I have a compaq laptop that runs the cpu at 55 °C which is equal to 130 - +°F. I have constructed a fan extraction system using my computer desk that has two fans underneath extracting the hot air from the bottom of the laptop unit and 2 fans directing cool air into the laptop  from behind. I am only getting a 5C temperature drop. That is when the computer is idle. If the computer is actively processing this temperature goes up. The core temperature is constant 4 degrees high the cpu.
I have read that using a hot water bottle is an effective way of reducing the temperature. I actually tried this method and it gave me much the same result as the fans. see this site http://digitalcomposting.wordpress.com/2008/04/30/water-cooled-laptop-stand-6/
Has anyone tinkered with the notion of using  a sealed copper coiled tubing with water or coolant. That the laptop can sit on via a thin aluminum plate as its base and acting as a heat transference agent then using the  natural heat convection en.wikipedia.org/wiki/Heat_transfer to cool the laptop. This is achieved by having one of the sealed ends of the copper tube immersed into cold liquid. The convection would presumably happen due to the heat and cold differences. Your opinions and further Ideas are welcome.

It's not a terrible idea - the trouble is the exterior of the laptop isn't designed to sink the heat directly.  What you need to do to help the cooling is cool the input air (look for vents that suck inward) and remove the hot air as expeditiously as possible.

Physically cooling the outer casing will do little, as its generally somewhat insulated from the really hot components inside.  All you can really do with an intact case is make it easier for the existing cooling system to do its job - which it seems you already have.

Exactly what I was thinking.

You could try just sitting the thing on aluminium for a start, as it will spread the heat out giving better cooling with the fans you've got already.

Some guy hacked his laptop, what he did is here:

You could use a PC watercooler kit though.

Laptop's by their very nature run hotter than PC's and are designed with high heat tolerances in mind.The temp's you describe are not out of the ordinary for a laptop and you should not be concerned.Should the temp actually rise due to a fan/heatsink failure the unit would shut itself down automatically thus avoiding any permanent damage to the CPU.If you are still concerned remove the plate covering the CPU and heatsink and blow out all the stuff you find there with a can of compressed air designed for electronic's
