I bought a Jetway Mini-top barebones nettop with an intel atom D525 ion2 combo inside. Please see here:http://www.guru3d.com/article/jetway-minitop-review/5
for some internal pictures for reference. The fan is too loud for me, so I want to go completely passive cooling. I have a cool-running SSD installed already. I don't care about aesthetics at all here, so here is my plan:
take the top cover off and discard it. The copper heatpipe that runs from the atom processor to the northbridge to the ion gpu is all connected and ends with about 3 inches worth of copper that is flush with the top of the case. I tentatively plan to buy a thin sheet of copper that is the same size as the top cover was and weld it to the part of the copper heatpipe that is flush with the top surface of the case. I have already removed the heatpipe and cleaned the thermal paste off and would do all welding outside the case. I would also cut some holes in the top copper sheet so that I would be able to line up and screw in the small copper plates to the cpu and gpu after slowly lowering the whole system down into place. I would also add a non-conductive rubber buffer along any edges of the case that could pose problems (there really shouldn't be any, it's mostly plastic)
My question for everyone here is whether they think that this copper cover would provide adequate passive cooling for this rig. The copper sheet would be 7.3x8", and I could get it in various thicknesses. I am guessing the answer is yes, based on the passive cooling systems of other D525+ion2 motherboards available:http://www.newegg.com/Product/Product.a ... -_-Product
The nice thing about this plan is that if I find that the temperatures are getting too high, I can either reinstall the small fan or keep welding additional copper heatsinks to the top of the case.
I do have a fair amount of rig-building experience, so I don't need advice regarding applying thermal grease etc., I would just like some thoughts on whether people think this will be adequate passive cooling for this particular cpu/gpu combo.
