i was bored today so i decided im gonna water cool my computer and do some serious overclocking. i looked at the water cooling systems available and decided to build my own. heres what im thinking , tell me if you think i need to change part of it: im gonna take a copper heat sink, drill holes running parralel to the bottom of the heat sink very close to the bottom of the heatsink and put copper tubing through there so the water will be goign through the bottom of the heat sink. id do the same kinda thing for the GPU. and if i get really bored maybe solder some copertubing on the heatspreaders on my RAM. im gogi nto use plastic or rubber tubing to connect everything instead of trying to use all copper. the radiator will be a coil of copper tubeing in some type of enclosure with fans mouted on both ends (both pulling air in the same direction of course) the resevoir, pump and radiator will all be on the outside of the case my fulltower case is already full. good idea or bad idea?
