Water Cool Chain w/ Pelt
 

Im building a WC system and I plan on using a pelt (172W) on the cpu (AMD XP 1800). Idealy I would like to add GPU, NB, and HDD water blocks into the chain. My question is, will the water be cool enough after the rad (BI extreme + 2 120mm fans) to cool the entire chain? What is everyones opinion on how this loop should be configured? I know for optimal cooling the CPU should be after the rad in the chain, but is the water cool enough to provide any benefit to anything else after it??? If not I suppose I could go with a second smaller WC setup for everything else and have the CPU on its on loop, I would prefer of course to keep things as simple as possible. Just looking for some advice!

Thanks in advance,

I would use a Y splitter and cool the GPU and northbridge in a separate loop. If you are mechanically inclined you could make a couple of manifolds to split the flow 3 ways before the parts that you are cooling and then rejoin with a second maniford prior to returning to the pump. It is kinda involved to get the flow rates properly tuned in a system such as that though.

2 120mm fans on the BI Extreme? Why? It is only big enough for one. stacking the fans or putting one on each side won't help too much. I think that the BI Extreme is powerful enough to perhaps cool everything, but the water will heat up considreably after it gets to the CPU so you will be throwing VERY warm water onto all of the components. Ideally, I would get a second radiator and have the water go like this: pump - rad1 - components - rad2 - CPU - pump

Ahhh, both very good ideas! Thank you very much. =P

As for the 2 fans, I am building a shroud that will somewhat resemble a funnel, with the rad at the 'bottom' and with the 2 fans sucking from the top, I thought a little negative pressure would do good for cooling (please correct me if im wrong) this shroud is going to be as air-tight as I can make it. Also while im on the subject, for the other side of the rad I was planning on using a tube/duct to bring in ambient air from outside the case. Im also deciding if adding a fan to draw the cool air into the duct would be overkill or not with the cooling properties of the BI extreme... At least if I use too much I can throttle them back a bit and have a quieter setup...

I appreciate your opinions!

Best way to do it is to have the fans pushing into the radiator. A fan can create way more positive pressure than it can nagative.
