NEED personal Help watercooling 2 MSI R9 280x's and an i7-4790k.

Okay, getting my first build ready, and with the r9 280x's running hot, I plan to watercool them and maybe overclock them a little or something. And especially to watercool my i7 processor as well. So I'll need a custom loop. Thing is: haven't bought a case yet and I will be taking recommendations. Other than that I will be having 1-2 HDD: 3.5 inch and one SSD. So I'll need mounts for that.

  1. corsair 750, 800 or 900D,

    any super/full tower from antec would be my recommendation.

    the cooler master cases are mostly just tin cans till there $500

    Yeah the 750D did look pretty good. The case looks very solid for radiator mounting space and with res and pump. I guess I'll go with that, and maybe I can fit a 360 mm rad on top and a 280 mm rad in the front? Will that be enough to cool everything? (1 CPU & 2 GPU)

    oh yeah, well into the overkill zone.
    i reccomend just starting with a dual d5 kit from XSPC. if you have a micro center that's local, get one there. if not Frozen CPU is the place to go.

    Is there a specific kit that I'm looking for? The dual one? I'm looking at a pump/res combo then just a pump. Can you link me?

    If your cards are reference, I would go for the heatkiller block http://www.frozencpu.com/products/22136/ex-blc-1585/Heatkiller_GPU-X_R9_280X_Radeon_Reference_Design_Full_Coverage_Water_Block_15025.html

    I also prefer alphacool nexxxos rads (ut 60 and xt45) but that's personal preference :D

    If your running pure distilled water in a windowed case I would go for solid black tubing to block the light (vs algae)

    Yeah that waterblock looks real good. I'll get 2, and the backplates, along with the bridge for 2 cards. But if I'm going with this kit: http://www.frozencpu.com/products/17221/ex-wat-224/XSPC_Copper_Raystorm_AX360_Extreme_Intel_CPU_Water_Cooling_Kit_w_Twin_D5_w_Free_Dead-Water.html?tl=g59c683s2175#blank

    what are the best fittings for the waterblocks? Please reply thanks!

    Alright seems very good. I guess if I go with that I should prchase or add another 240 mm radiator in there?
  8. Another 240mm would be good, a 120mm should be enough too, but if a 240 i would go for one...

    Some say 120mm radiator per block plus another 120mm are enough, but I wouldn't skimp on radiators :D

    The kit includes some barb fittings, for 2 GPU blocks with bridge you'll need 2 more, also 2 more for the additional rad. So you can get whatever 7/16" x 5/8" (size of the includes tubing, ID x OD) fitting, either you stick with barb fittings or go for compression fittings (more expensive, but better lookzz).
    You could also 'copy' the kit (put the parts separately in the cart) and replace the barb fittings with compression fittings, same goes for the tubing itself. 7/16" x 5/8" has not that thick walls, 3/8 x 5/8 is a bit thicker (and the inner diameter is therefore smaller) and won't kink that easy.
    If you planned the loop and have many bends, 3/8" might be better.

    I'm on 2g right now and therefore to lazy to link some examples (loading takes forever)

    Alright I'll probably P.M you later, but i need like a ballpark answer on this: obviously I'm going to over clock the cards and the CPU, and with EVERYTHING my build, how much wattage of a power supply should I get?
  10. I would get atleast 850watts, a high quality 750w might do it to but it would run at high load the whole time. Especially if your overclocking, a little overkill like a 1000w PSU might be a good idea

    Seasonic, xfx and corsair make good PSUs, what's your budget and are you living in the US?

    I'm still on home leave, I could help you more at home...

    I don't really have 1 specific budget, but i would like to stay under the $200 price range. I live in the U.S. There is a 1300 watt full modular power supply on sale I was wondering if i could snag that or if that might be too much overkill..

    UPDATE: By the way I would like to have a fully modular power supply so I could sleeve of buy aftermarket cables to match the rest of my build.
  12. Which 1300w PSU is on sale? Although most PSU in that price range are good/great, some are better than others at the same or a better price.

    It also depends on the efficiency @50% load and @100%, a PSU with 1300w might only be @50% load while a 1000w is @65% load... But all 80+ gold should be fine.

    There used to be a list with ratings of PSUs, I'll try to find it...

    Yeah the one I'm looking at is the EVGA Supernova Power supplies.

    1000 watts: http://www.ncixus.com/products/index.php?sku=88518&promoid=1413

    1300 watts: http://www.ncixus.com/products/?sku=85573&promoid=1248

    They're both basically the same price after rebates, but I want to get what's best for the build.
  14. They are both tier 1, I would go overkill and take the 1,3kW if they're the same price...
    What other parts next to the 2 280x and the 4790k are you going to use?
