I'm thinking about watercooling my system and have searched google for some answers regarding watercooling a multi-processor system, but came up empty handed. My goal is to water cool both my processors and my gpu (radeon 9800 pro). This is the system I'm looking at (I'm trying to stay under $250 total): http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1028632&CatId=499. Can I safely do this on one water cooling system...linking each part inline? Roughly, how much warmer should I expect the temperature to rise for each component after the water has flowed past the previous ones? If I shouldn't run them inline like this, is there something I can add to the system to cool the water in between processors (without buying a whole new cooling system)? One last question: Do you think running a watercooled system like this would pull more power than 2 processor fans and a gpu fan or less? Thanks in advance!

Is your system currently overheating ? List of Lists.

No overheating. I'm considering this system because I plan on overclocking the graphics card a lot in the future and have had my processor fans stop on me a couple of times because of all of the IDE cables hanging around them. I also like how it comes with an lcd panel displaying temperatures, overheating protection, and adjustable fan speeds (for quieter running or higher performance). Should I look for something else? I've seen some great graphics card fans, but watercooling really interests me. I'm looking to change my computer some as it hasn't changed at all in the last year or so.

"...because of all of the IDE cables hanging around the..." Try cleaning up the inside of you case first, cable ties, guides and management is your friend :-) Completely useless? I can always be used as a bad example

lol, alright. i'll do that :). i'll pick up a can of compressed air too to get any dust out. from the responses, it seems watercooling isn't the way to go? should i avoid watercooling then? i've been interested in it for a few months for a variety of small reasons. i'm not looking for anything really high performance, just something to cool my processors/gpu down more than the fans are while keeping it fairly quiet. i checked my processors' temps and they're each running around 50C idle (a few minutes after startup while sitting in the bios...nothing much). that seems pretty warm to me :-/. if it's that at idle, than it must be pretty hot when under load (keep in mind these are 1.5Ghz Athlons....I've seen 2.4Ghz P4's run cooler and I've heard P4's run pretty warm). thanks for the suggestion :)...i'll reorganize the cables.

Water may be the way to go, thats what they did with the high end G5 Power Macs, however, I myself don't feel all that comfortable pumping water into an environment chocka block full of electricity. You may want to have a look at some of the silent high performance air coolers offered by Zalman, just make sure they will actually fit first :-) Completely useless? I can always be used as a bad example. There are 10 types of people in the world. Those that understand binary, and those that don't.

I'll look into Zalman and see what they have. Thanks for the suggestion :)
