    Hi there,

    I'm about to venture out and replace the air that cools my important components with water! Though I do have some things that need clearing up.

    Firstly I need to make you aware of what I'm cooling so that you have a better understanding of what I'm going to cool and it is as follows;

    Amd Phenom II X4 10 @ 3.65
    2 x Palit GTX 460 overclocked in SLI
    *Possibly* the gpu ram with water cooling, otherwise I'll just stick ramsinks on

    So I've done some brief reading on water cooling and found out that I'm going to need;

    Cpu waterblock
    2 x GPU waterblock
    Radiator
    Resorvoir
    Pump
    Piping
    Fittings for the GPU blocks
    Maybe some ramsinks and some sort of heatsink to cool the VRM

    Am I missing anything?

    I understand the waterblocks and I'm almost sure about the fittings and piping and I don't understand anything about pumps, resorvoir or radiator.

    Fittings, Are barbs the small connectors that allow the pipe to be connected to the water block? In that case my Cpu waterblock comes with 3/8" barbs and some 3/8" piping has been purchased. I've also got some 3/8" barbs for the GPU waterblocks so I should be fine!?
    About the 3/8" piping what does 3/8" mean? 3 eighth of an inch in width?

    Now about the radiator, does it need to have a fan attached to it? (Not that I'm worried about that or the noise) Also what radiator would you recommend, I don't want to buy something thats going to be an overkill. I was looking at these two:
    http://www.overclockers.co.uk/showproduct.php?prodid=WC-003-BX&groupid=962&catid=1523&subcat=
    http://www.overclockers.co.uk/showproduct.php?prodid=WC-004-BX&groupid=962&catid=1523&subcat=

    I noticed that one is 120 and the other is 240, I don't want to go on the notion that the bigger the number the better but what does that mean?

    Also I was thinking of pairing it with with this pump/rad combo, especially since it uses a dvd drive space: http://www.overclockers.co.uk/showproduct.php?prodid=WC-007-XS&groupid=962&catid=1845&subcat=

    What about the liquid used and maintenence. I'm sure I've heard somewhere that you can get non conductive stuff but I'm not sure.

    What do you guys think?, if theres any simple but crucial advice that I need I'm willing to hear it. One bit of advice that I've heard is to do leak testing.

    Thanks

    If you're only interested in water cooling your CPU, you could get a kit such as the XSPC Rasa (search FrozenCPU.com for it). It is relatively cheap (under $150) and comes with all parts you need for an entire water cooling setup (except coolant/distilled water).

    If you get the rasa 360, which comes with a 360mm radiator, you could buy 2 GPU waterblocks and include the GPUs into the loop too. I'm not sure if the pump will hold up though.

    I was going to say that you should probably customize your own loop, but that's such a great deal that I think this is the better option.

    The great thing about the Rasa is its not a pre-sealed loop, so down the line, you can always add in a larger rad, more pwoerful pump etc as your needs change. The fact that it comes with a pump,rad, res, waterblock, barbs, pipes etc makes it great for first timers.

    The bigger the number, the better performance. Simply because the number ere denotes the size. The 120 is 120mm in size and can only hold one fan on either side. The 240mm is double the size and can hold two 120mm fans on either side for a total of 4 fans in push/pull. Definitely stay away from 120, but if you're including a CPU and 2 GPUs in the loop, either get a 360mm rad, or better yet, 2 240mm rads. You could go something like this (don't hold me to it:

    Pump -> rad1 -> CPU -> rad2 -> GPU1 -> GPU2 -> res -> pump

    As for liquid, some people like colored liquid coz it looks cool. It doe require a little more maintenance as it, over time, leaves residue along your loop. If you really like having color and don't mind the extra maintenance go for it (I did). If you're going for color, you should get the Feser from frozenCPU. They sell in various colors, are reactive to UV light and compeltely non conductive.
    Or get Distilled water from your local grocery/supermarket store. They are also non conductive. Some people like adding a few drop of anti-algae to it.

    This kit is a bit pricey, bu an excellent starter kit that takes out many of the leak points, and makes installation a cinch. http://www.swiftnets.com/products/h20-x20-edge.asp I would read up on it, there are things like variable speed in the pump and the fans. Only thing you would need to add to make this kit work would be GPU blocks of choice;)

    I have the 320 version, it cools a i5 750 at 4ghz (1.4V) and an OC GTX470 (overvolted). I could easily add another card and still be pleased with the temps.

    Lol nice, didn't know you could use normal water. I also didn't think I'd need two rads, thats why its good to ask and not guess:rolleyes: Thinking about it, I am going to cool two GPUs. If I get two 240 rads, does that mean I have to get 8 fans?

    Helpful diagram as well.

    About the coloured liquid. I've purchased these pipes :http://www.overclockers.co.uk/showproduct.php?prodid=WC-050-OK&groupid=962&catid=1530&subcat= so I think coloured liquid may be a waste. Supermarket water it may be then:roll:

    I'll also have a look into that rasa 360 kit but I think I'll still take this route.

    Considering you're only cooling 460s, one 360mm rad should be ample. Though the kit will come with 3 fans, you'd still need to buy a total of 6 fans (you can get Yate Loons for about $5 a piece), and then sell the 3 that came with. The reason you can't use those is because its best to have 6 identical fans around the rad.

    So do you think there would be major advantages if I went with two 240s over 1 360?

    I'm certain two 240s would perform better, but 1 360 would be adequate too.

    Two 240s would make fitting everything inside a little more difficult, would require you to get more pipes and fittings and be more expensive. If you were cooling two 580s, I would certainly reccommend that, but for 460s, one 360 rad should get the job done satisfactorily or better.

    I agree with the fitting thing, I have a 240 and a 120, and coupled with a 470 block directly next to the 120, it makes everything hard to maneuver in the case. The 360 will be your best option for your configuration.

    True, One 360 it is then. I'm already Not sure where the rads are going but hey I should be fine! So I'll have a look at some yate loon fans, I've heard good things. Can't I just put 6 low Rpm fans?

    Yate Loons push about 45CFM and are fairly silent. So they should be good for you. Also, the great thing is they won't hurt you should you accidentally get a finger in them. Six of them will do the job.

    However, if you want something more heavy duty, you could get Scythe Ulta kazes. They push over 100CFM but will be relatively noisy, cozt about 11 a piece and would require case grills to be safe.

    Go with yate Loons. They are quality fans. Don't cheap out or you'll have fans die on you, particularly when they get dusty and there's more load on the motor.

    Agreed with the Yate Loons, I have 5 Mediums and they keep my system nice and chilly while staying relatively quiet. :rockout:

    Yup, Yate Loon mediums are ideal.

    Can't say for sure. 120mm fans should be 120mm (12cm) in diameter. That specifies length and breadth.

    Ok, so calculating using Pythagoras theorem, diameter is 13cm, which probably means it is a 120mm fan (the extra 1cm is the grill). So it should be the right fan.

    Checked it out, Whats with the 650w recommendation?

    I've actually got a 650w my self but now I'm not sure.

    What about the pump/rad combo I mentioned earlier?

    The one that takes one dvd bay has a pump that can do 200 lph
    The second one takes two dvd bays and the pump can do 750lph

    so?

    At that time, we didn't have the efficiencies that we see today with newer PSUs. So I wanted to make sure that even if someone got a PSU that wasn't 80 Plus (Silver/Gold) certified they were above the 80% PSU threshold (depending on PC setup: # hard drives, etc).

    I've never used that combo so can't speak from experience but personally I would not go for a combo. Should you want to go in for a larger pump or res, or should the pump die down the lane, its easier to upgrade if you have individual components.

    The general rule is: if your loop is restrictive you want as high lph as possible. What causes this? Well, it depends:
    -having more then one block (for example, CPU block + full video card water block)
    -any kinks in the loop
    -the waterblock itself
    -etc

    So as long as the block itself isn't restrictive you could get away with a 200 lph pump. For example, water block kits, etc. But if you are using more then one water block you should get the 750lph.

    Would a 750lph also mean that heat would be removed quicker?

    Not necessarily. Depending on the pump it could add heat. But don't worry about that. This is what having a good rad is for. And IMO, any added heat from the pump shouldn't cause an issue. As a rule of thumb I suggest keeping your pump somewhere in your case where it can get good airflow. That would eliminate that concern.
