Is a 360 mm Radiator Enough?

[Shadow Bullet]

Is a total amount of 360mm of radiator surface area enough? (By this I mean a 160mm (x2 80mm), 1 80mm and 1 120mm radiator) to cool a 5820k, and dual Titan X's?

[Gofspar]

not really.

Should be decent, though you may want to go for larger radiators if possible.

[kittsykat]

it should be good enough for decent temps especially if their thick (45mm+)

 

remember that titan X's run hot so with two of them and an X99 CPU, more will definitely be better.  Also if your at all considering overclocking go with more

I added a dual 80mm rad to my PC more because it was dirt cheap and I wanted to see if it would make a difference. it dropped my temps by only like 2 -3c if even that. 80mm rads are worthless. if you have the money for 2 titan X's you have the money for real rads.

Rule of thumb is 120mm per device (minimum)

you need 240mm per GPU(these are dual GPU cards so 120mm x 4), and 120mm for the CPU to really be able to cool it all. so 600mm of rads is your starting point.

Titan X is a 250W TDP single GM200 GPU card...

Your calculation is still right, and yes 600x120 is what he should have.

If you have the room for it, I'd say get 2 360mm's or 2 480mm's for the best temps & noise.

I'm not sure I get what you mean, but I think you're saying you've got a dual 80mm rad and a single 120mm? If that's right then not counting thickness that's 27,200mm^2 whereas a 360mm rad is 43,200mm^2. For perspective a dual 120mm is 28,800mm^2 and a dual 140mm is 39,200mm^2.

 

That's ignoring literally *every single other possible factor* about your planned loop to show the scale difference here.

 

For reference I present the current AIO reigning king of Frostytech's 200 watt testbench, the Nepton 280L http://www.frostytech.com/articleview.cfm?articleid=2752&page=6 Simply put they dump 200 watts of heat into it to see how well it cools and report the results as a delta from ambient, so the 10.6c result means that if ambient is 24c then it manages 34.6c at the thermocouple. (Meaning the cores in the CPU would be hotter by ~10-20c depending on the TIM.)

 

You're proposing dumping (at stock speeds) 640 watts of merciless heat into only ~70% of the frontal area of that cooler, which is a bad idea before we even consider anything at all about whatever radiators, pumps and waterblocks you've sourced. If you're planning on this you'll want to go much bigger. Also you want to avoid having a bunch of rads if possible as you're adding points of failure and pressure on your pump(s).

Do not use the ft03 for water cooling that setup. 

You are better using air.

 

P.S. I assumed that was the case you were using because i had a similar idea one time
