I was thinking about how to make my own water block when this idea hit me: Why use a water block at all? If I glue a chipset heat sink onto the CPU and construct a box over it, then I can run water directly over the chip. The resistors can be coated with silicone and unless the CPU chip can rust, there shouldn't be any problems - right?
(I posted this because I'm wondering why I haven't heard of anyone doing this before - please tell me if you think of something that could go wrong
I'm not sure I'd like to try something like that on my AMD processor... even with the silicon application. I honestly have no clue what it could do to the chip itself... certainly is a question worth asking.
