    Hi all/. I am new to this forum and hope to get some info. I want to get into water cooling. Any advise that can be given is mucho appreciated. Even Recommendations on where to buy. I am thinking of making a watercooling setup outside my case for my 7970 in crossfire. I may over clock some day but the noise is the big thing at this time.Thanks

    Welcome to TPU, home of the awesome!

    I fancy your idea to watercool your 7970's; mine are on water too :p

    Running 2 360 rads with Scythe GT 1450s, and I'd say the loudest thing is probably my pump :D

    Thanks . What pump are you using.Still trying to pick this stuff out. Water blocks. and RES. I have a spot in a cabinet that is part of my desk with a door. I want to put everything in there and make it look clean. My case is a corsair 400R. Not enough room for what I want.

    I have a 550d which is a similarish to your case which I am watercooling but you are looking for more rad space than I was. I put a 240mm monsta rad that is 80mm thick up front where the drive bay goes to cool my 2500k and 7970. I also used the corsair SP fans. When I turn all the fans down my rig is very very quiet, near silent, and my 7970 reaches a high of 50c while overclocked. I usually keep the fans a bit higher just because I like better temps and the noise is not that bothersome.

    [​IMG]

    That is just my rig. I am showing you this just to give you ideas. You can do whatever you want. I just love my apogee drive II and would recommend it to anyone because it saves space and works awesome. You are probably going to need at least a 240 if you are just doing your gpu's but anything more than that just means you can go quieter. You need to do is figure out how much you want to spend, space you want to use, and how much cooling and quietness you want. Be creative and figure out where you can fit your rad and how your tubing will run. I really recommend getting some good fans because that will be how you make your rig quiet. You could get some low rpm yate loons like manofthem which are near silent. It might be a good idea to get faster fans and have a fan controller to turn them down to a sound level you find acceptable. I feel like I am just throwing out information, but that is because I am just trying to give general information since you did not ask for specifics.

    Some good shops are performancepcs, frozencpu, sidewiders, and jabtech.

    jesus did you take a piss in your reservoir or whatever and use that as liquid? What is with the tubing color?

    OP: Just get a Maelstrom res, MCP35X pump, 2 EK blocks for your 7970, and 360 radiator, but id run a 480 radiator honestly.

    I run 2 x 7970's with XSPC blocks for them.


    1 x 360 plenty but 480 better

    This. Look up pics of 400r watercooling and use their ideas. There is some interesting stuff in just google results. I wasn't that lucky with my 550d, I had to figure out all placement myself.

    You mentioned that desk space. You could probably do something very cool with that. I have seen some very cool desk watercooling stuff out there.

    All is see is flaws. I see the scratches on my rad, the tim smudge on my rad, the tubing is cloudy. Yes MxPhenom, I see it. The water is clear as clear can be. What I get for using cheap hardware store vinyl. It is going to be replaced with xspc black tubing soon enough. I don't use a res because I find it annoying. My rad does a good enough job and cutting the res out made my loop simpler. But this isn't about me.

    You will probably get everyone telling you which blocks to use. Here is a review of 9 different 7970 waterblocks.

    Thanks for all the info.All the different suggestions are great to see. Lots of different ideas and I am always changing my mind. I am still considering the desk thing.I think I will go with the 480 rad instead of the 360. Piece of mind and room for expansion if needed.

    I was looking at those monsta rads. They seem like they would be good for slow fan running. Also the swiftech QP rads are suppose to be good with slow fans. Any thoughts? Pronlems is they don't seem to be in the size I would like. I was thinking of a quad fan rad for the gpus. Then a 360 later for the cpu.

    The monta rads, which I have one, may be low fpi but are just so thick they need a lot of static pressure still. I use the corsair fans and they do pretty good and are quiet. Also, I like the monsta rads just because ... well look at it.

    For slow moving fans you are going to want a any low fpi rad really. Those thermalchill rads are great for that.

    I am thinking you are looking at more rad than you need, not that that is a bad thing. One 480 should be enough for slow fans especially in push pull. I am sure someone will disagree with me on that.

    Where are you located?
    I see that they were bought out...

    I personally like EK and Aquacomputer. I have owned several XSPC rads as well. I hear/read that many like Phobya rads as well.
    I frequently use these two sites to buy my water cooling gear:
    http://www.performance-pcs.com/catalog/index.php?main_page=index&cPath=59_457_667
    http://www.frozencpu.com/cat/l2/g30/c95/list/p1/Liquid_Cooling-PC_Water_Cooling_Radiators.html

    Here is a good thread to help you understand what you will need:
    http://www.techpowerup.com/forums/showthread.php?t=52032&highlight=how to water cool

    It would also be helpful if you filled-in your System Specs in your User CP.

    Great thanks. FP seems to be a good retailer. I will try to figure how to fill in my system specs. Thanks

    Cant find heading in profile for system specs.

    Sidewinders does not have Thermochill radiators.

    http://www.sidewindercomputers.com/radiators.html

    Why so bent on the Thermochill radiator if its hard to find? Why not take a look at EK XTX, Alphacool XT45 or UT60, or XSPC RX series?

    To put your system specs in, its in UserCP on the side near the top.

    EDIt: They are all about the same price. XSPC RX480 and Alphacool UT60 480 are $119 and the EK XTX480 is $124 on performance-pcs.com

    Oh I know they are. Known as the King of radiators...............and still are really. But they are super hard to find new.

    I think the new runner up is the Alphacool radiators. Martin and martinliquidlab.org hypes them up a lot. the XT45 and UT60s. Im still debating if I want to go 60mm thick or 45mm thick radiator when I get a 360. haha.

    What do you guys think of the Alphacool monsta. They are thick. The 3 fan would fit in my desk. Quiet.. Would the 3 fan be enough or should I go 2 3fan radiator

    I can fit the 480. This would cool both 7970 and I can have the fans on low. I will later add to the system to cool the cpu and get rid of the corsair. What would be a good pump with this rad. And would this rad be to thick for fans on low

    You will need to run push pull with the monsta radiator. And just because its a thicker radiator does not mean its better. Martin will consistently say that front surface area is better then thickness of the radiator. so going up to a radiator that fits 140mm fans but is thinner then the 120mm fan radiator itll be better.

    You actually will need to run your fans faster on a thicker radiator or in pushpull to get air all the way across the radiator fins. Thinner radiators, allow for much lower RPMs, and that are still able to hold their own again thick radiators. Thick radiator are great though if you do want to run your fans at about the 1600rpm mark. Which is why thin radiator performance kind of drops off.
