100% ghetto home made watercooled SLI laptop. This is the kind of thing I think of to keep myself from being bored. Ghetto because I wanted minimal outlay while building one as a project to play around with the cooling on it. If I screw it up and stuff dies no great loss. (Of course naturally when I first fire it up the Extreme Edition CPU 3940XM is all of a sudden dead - I'm not inclined to pay ~$250 to replace so testing for now is on a 3.8ghz quad eating 55W instead of a 4.5ghz eating 90W) Ingredients: 1/4 inch OD copper tube from hvac supplier DIY waterblocks, rads and heatplates harvested from the stock heatsinks Bunnings 6mm pvc soft tubing (more heat resistant silicone tubing is in the mail) There has to be zipties to qualify as ghetto - there's one black ziptie on there in the upper right - when complete all joins will be double zip tied as hose clamps because there just isn't the clearance for anything bigger in a lot of spaces Tiny $10 pump and 55c boost converter pcb arrived today so I can start wiring an internal pump run off 5V (SATA or failing that, USB) inside the empty optical drive bay (lower left) Along with a couple of screw top saliva specimen tubes that I will be making into an air trap/reservoir/fill&bleed port.
