    Hi, I'm hoping to be putting together a computer soon and I want to have it watercooled, now I am completely new to watercooling, so lets just pretend I'm an idiot that needs to have everything explained, haha! So anyway, I really have no clue what I'm doing, I think I have the basic parts decided on, but I don't know if they're compatible and I still need to choose tubing and fittings I think :confused: So yeah aaaaanyway, here is my case:
    CM Storm Trooper w/Window (http://www.pccasegear.com/index.php?main_page=product_info&cPath=25_31&products_id=19722)
    and here are the watercooling bits I've selected so far (as much feedback as possible thanks!)
    CPU Waterblock: Bitspower Summit EF CPU Liquid Cooling Block - AMD Series - Ice Red

    GPU Waterblock: Heatkiller GPU-X³ 79X0 Radeon HD 7970 Reference Design Full Coverage Water Block

    Radiator: XSPC AX240 Dual 120mm Radiator w/ Aluminum Enclosure - Black

    Pump: Danger Den / Laing DDC Rev. 3.25 Liquid Cooling Pump - (12 Volt -18 Watt)

    Resevoir: Alphacool Repack Single 5.25" Acetal Reservoir - Special Edition White
    So obviously I'm missing the tubing, coolant and fittings (idk if I need fittings [remember I know nothing hahaha]) so yeah as much help as possible thanks, also if you could tell me if this is all compatible, decent quality and what I may also need. Thanks!
    Also preferably a transparent Red tubing and UV Red coolant :)

    Hi there, welcome to the adventure that is water :toast:

    The loop components are not as important as the loop integrity. Without looking at the parts the things you need to watch out for are:

    Most loop components have 1/4" threads. So all your fittings must be compatible to screw in to that.

    Your tubing size is vital to leak prevention. Tubing is best understood as ID/OD which means inner and outer diameter. It is the INNER diameter which is most important. You need to select a tubing size with an ID equal to or slightly narrower than your fitting width. Lots of guys use 7/16" ID tubing over 1/2" (8/16") barbs. I cannot speak for compression fittings but the same rules apply although i think with compression fittings the OD is also important.

    Loop order is not vital but the reservoir should feed the pump, otherwise you'll spend forever getting air out of it.

    Create a drain point in your loop at the lowest point. Some radiators have drain points (yours doesn't?). Use a 'T' fitting and drain plug at the lowest point in your loop (Google it for ideas).

    Figure out your tubing position and lengths before cutting and attaching. You can unscrew fittings by poorly planned tubing as the torsion in some set ups can slowly unscrew the fitting, leading to leaks.

    If the above is a concern, use rotary fittings - they allow the tube to turn in situ.

    And make sure your fans match the radiator. Dense radiator fins are best for high pressure fans (more noise, better cooling) and low density fins are better for slower fans (less noise, decent cooling).

    Finally, a single 240 radiator is okay for what you have but wont make the best case for overclocking.

    I'd add more but need to shoot off to work now.

    Try this forum for even more ideas and plenty of folk with better knowledge than me.

    Ok, thanks for the feedback guys, after looking around I think I may have an Idea of what I want to get, also do the individual parts (radiator, pump etc. come with fittings and clips or no? If not can you tell me if the fittings I've chosen will supply the clips? Might be a newb question haha)
    Tubing - PrimoChill PrimoFlex Advanced LRT Tubing Clear 3/8ID 5/8OD 10ft

    Fittings - Bitspower G1/4 Matte Black 3/8 Fitting (I think I need 12? Correct me if I'm wrong though haha)

    CPU Waterblock - Koolance CPU-380A CPU Water Block for AMD

    GPU Waterblock - Heatkiller GPU-X3 79X0 Water Block (Hopefully getting an MSI Radeon HD 7970)

    Radiator - XSPC AX240 Radiator Black

    Resevoir/Pump combo - XSPC Acrylic Dual 5.25in Reservoir Pump Combo with Two Laing DDC

    Coolant - Koolance Fluorescent Red Liquid Coolant 700mL

    So yeah, thats it so far. Open to thoughts, and any input on the fittings and clips are appreciated!
