Depends on what you're looking for - the Zalman watercooler is almost totally silent, one of the main reasons it works so well is the large volume of water in the reservoir. It is, by all accounts, easy to setup. Because the cooling is entirely passive, it won't cool as well as the other model, but then it has near silence as its main benefit. That and the fact that it looks damned cool 8). I'm fairly sure that Zalman do blocks for the graphics card and northbridge as well (but don't quote me on that one)
 
As to the second - who's the manufacturer? It looks like a bog-standard Eheim pump, but I couldn't say who makes the other parts. This version will make some noise because of the fan and pump - but it's still quieter than air cooling your CPU. You should also be able to extend this to cool other parts of the PC, but check before you buy!
 
Bear in mind that you will still need some airflow through the case to cool things like hard drives - so you won't be able to get rid of fans completely - but you could get away with some low speed quiet fans.
 
Hope this helps

Sorry about the German:)
 
This can all be found on this wesite

I'm going to Heidelberg next week to buy one of these and believe me or not, I still cant make up my mind as to which one I want :x

Personally, I'd go for the Zalman - but only because it's quieter and looks [censored]ier! But that's only my personal preference!
 
It depends on whether you want performance or looks - the Zalman looks good, but isn't a spectacular performer (I think most of the cooling comes from the sheer volume of the reservoir - about 2l); the Eheim/Black Ice/Titan solution may give you better performance, but doesn't look half as [censored]y as the Zalman.
 
All IMHO of course

I know, it looks great, and the blue will match my PC, well, the lights in my PC, my PC itself is black with little red and a window on the side with blue lights and fans and one red fan and my screen card has 2 fans with built in blue lights.
 
I cant find a pic of my box, but this is a nice one too:)

I like looks, but I think performance and reliability has the upper hand in this situation.

Sorry, the other option, the one with the separate parts in the picture.

Ah ha, I thought so, but I just had to make sure, you know

Now I cant make up my mind, I was browsing around again (I know, I'm evil), I'm sorry.
 
But now I have to choose one of these 2 and I dont know which one to choose. The one is a lot cheaper but I still dont know which one to take.
 
1.) Thermaltake BigWater Liquid Cooling System - Universal 99€


 
2.) Alphacool Xtreme Pro Set 240 12Volt - Sockel 478 269€
