Water cooling my own designed case

[Marshall Rico]

Hello,
After researching pc cases for about a week i finally decided to make my own i have a access to a discounted laser cutting service in canada so i thought why not(i also love a challenge). Anyways moving on i wanted to ask how i can calculate the amount of water cooling needed for a 780 TI (2 in the future) and a i7-4770K, overclocking will be used once i set myself up and are happy with rig im in no major hurry. ATM my case design incorporates 2, gtx xtreme 240mm radiators (or any radiator of similar design) in the top with sets of 120mm gentle typhoons in push pull, this wc loop would then run down about 300mm to the motherboard with half of that being vertical (are pumps going to be a problem running water vertically for that length?) the reservoir would be located down the bottom with the motherboard.

Can anyone see of any reason why my design would not work if so please post below so i can adapt my design to make it work

Thanks in advance
Marshall

2 290x watercooled would save you money? The performance difference is about 0 and you can still OC them like crazy.

For a 4770k, 780ti SLI or even a 290x Xfire, you will need at least a 360+240 rad both 60mm thick for low fan speeds and less noise. Keep them in pull only to save space. a 30mm rad with 50mm of fan speed=85mm whereas a 60mm thick rad with a 25mm thick fan=85mm yet allows the rig to be more quiet w/same performance.

Pump and tube res depends on location and spacing. How much space do you have in the bottom?

One huge help would be the actual design/layout of the case.

Real quick design in sketch up im a terrible user of the program so i will admit it looks terrible at the moment

Simply its two boxes that measure (WXDXH) 300X300X140 that are connected by a vertical wall acting as the motherboard tray

The radiators up top have 90mm between them and the piping runs from the back towards the vertical wall, the holes allow for pipes and cables to run down/up the back wall to get access to the motherboard while remaining out of sight

Primary material will be aluminum with a acrylic or plexi glass surrounding the motherboard for looks

Down below simply stores the power supply and hard drives i will be adding fans to keep an air flow to the motherboard and lower box but havnt yet put it into the design

Probably should have just posted this on the case forums as now the design of the case is in question rather than the water cooling side : / my bad

How many fans will you have blowing in to the case to supply the rads? and where will you put them?

I would agree with NeverBackDown here, for a CPU + dual GPU loop I would use at least a 360mm + 240mm 60mm thick rads with push fans.

One of the main reasons to go for water cooling is great temps and a quiet rig.

the more rad space you use the lower you can run your fans (in theory), its generally accepted here on the forums that a 360 + 240 60mm thick rads are the ideal amount for this kind of loop.

Also the Gentle Typhoon fans are out of production, if you cannot find enough in stock at our preferred retailers I would suggest corsair SP120 Quiet edition fans as a replacement.

Personally I will vouch for the corsair fans. I've found them to run perfectly silently in my rig, even on 12v. I don't hear them at all.

Corsair SP fans are too loud after 7v and even then 7v to me is pushing it.
