Ok guys, i've had it with the loud noise the constant crashes in the summer for my pc....i'm taking the plunge and going over to water cooling. Just ordered all my parts from various websites, and hopefully they should all come in by the end of the week .....as for the waterblock, I'm gonna make my own. Why? just cause I can ......now here's what I'm building: a really big cubic water block, about 2inch cubed....it will have water going in right through the center, and then have pipes around the block (think heat pipes) just to circulate the water even more around the block. Now the only part I'm having problems with is the water impingement structure...anyone have any thoughts or ideas on the best way to design that? I'm looking at other waterblocks and can't decide which one would be the best. I'm open to any advice you guys have. So how can i maximize water impingement?
