Building custome laptop cooler - water based

Hi,
As I have an overclocked full aluminum laptop which due to its design dispenses a big amount of heat through its body and gets uncomfortably hot (60+ Degrees - meassured with heat gun) during demanding gaming sessions I was thinking of building my own laptop cooler.
As of now I have two designs in my head and wanted to hear your thoughts on them:

1. Water colled -- I take a standard 3 fan laptop cooler and place several connected small cooper pipes on the top and the bottom of the cooler which are then connected to a small usb water pump. The laptop would rest on the top copper pipes and transmit the heat to the bottom pipes where it is able to cool down (possibly I would also install cooling fins on the bottom)

2. Copper based -- Take laptop stance and cut a rectangle into it. Then I take one of my old desktop GPU cooler (Accelero XTREME 9800 - http://www.hardwarecanucks.com/forum/attachments/air-co...) and connect a 15cm x 15cm copper plate (with a few holes drilled into – for air flow) to where normally the graphic card goes. If everything goes smoothly the copperplate will be on top of the laptop stance and the GPU cooler connected to the bottom.

Both options would cost me less the $50.

Here a pic:


Apart from maybe diamonds and silver (correct me if I am wrong), copper (Thermal Conductivity of ~ 400) is a perfect heat transmitter.

To cool a CPU it makes sense to use liquid and water (small area which gets very hot). But I have a big area which does not get that hot.

A big copper plate will surly attract more heat than a few copper pipes and a professional GPU cooler might actually cool the copper more effectively then my water based solution – in the end it can never get cooler then room temperature

What are your thoughts?

So what do you thing will yield the better results?
Would you do it differently?

Best,
Chris

 

Have a dual way. Water cooled and copper.
