How many radiators should I have?

[switchd]

Doing my first custom water cooling build and need advice on the build.

I attached my shopping cart from EKWB, if possible let me know if here is a problem and I'm also concerned if two radiators is to much or could I run just the one larger radiator below.

Here's the link to my PC build, ignore the closed loop cooler that's so I won't get a error in the build.

As well I was planning to change the Titan to a hydro copper, just not listed.

You should buy the D5 pump, it's the better pump you can get.

One 480 rad is more than enough.

Thanks! I'll look for the pump as well.

https://shop.ekwb.com/ek-xtop-d5-pwm-acetal-incl-pump , think this is it?

Yes, it's an industrial pump but is rebranded by aplhacool, ek ecc ecc.

Can't go wrong with that.

1 is fine if your just planning on cooling your CPU

Cpu and GPU, it'll be a hydro copper Titan with 5820k. Would you think one quad radiator in the bottom be alright? Or maybe two average size ones.

EKWB has that crazy large one just worried it's going to take up all the room below where I want to put the pump and Rez.

Which case you got?

General rule for normal cooling is 1x 120mm rad per component, that being said I'd add an extra 120mm for good measure but that's my personal preference. If you plan on overclocking you'll want even more rad space.  So a 480 would be plenty with room for some overclocking.

If you have the money I would spend the extra to put your CPU and GPU on the own loop with there own Rad even if they were smaller like a 360 or a 240mm but a quad would work also.

Alright think I got it, just need to see what fits well and good to go! Appreciate everything!

If you're buying at the EK store, i'd pick up 4 vardars in the colour you like (black, grey or white) they are excellent fans. Most people add more rad space simply for aesthetics, like the rear 120/140, doesnt do much, but it can look nice  I would also get a bottle of copper sulfate (PT nuke) since it lessens the chances of growth and it's dirt cheap

Darn, I was too late, you've already picked a 'correct' answer. Well, here's a more correct answer: http://linustechtips.com/main/topic/332558-how-much-rads-for-cpu-gpu/?p=4541663

 

I explain the math and how to use the chart in that post. For your parts:

 

TDP of CPU: 140W

TDP of Titan X (why not just get a 980 ti? They perform basically identically?): 250W

 

Pre-OC TDP: 390W

 

390 / .00022 {Using the 360mm version of your rad from EK in the chart I linked} = 1,772,727.272

1,772,727.272 / (120 * 30) = 492. Thus, your 480mm radiator is just barely sufficient for a non-overclocked heat load. How much heat will you have if you overclock? Well, truth be told that depends on how far you can push your components, but 200W on your CPU and 275W on your graphics card aren't out of the question.

 

475 / .00022 = 2,159,090.909

2,159,090.909 / (120*30) = 599

 

So...if you OC both, you'd probably want another 120mm radiator (480 + 120 = 600). You could also play it safe and get one of the Monsta thick-rads from alpha cool. That would change the math to being:

 

(2,159,090.909 - (120 * 120 * 80)) / (120 * 30)

 

because I believe those rads are 80mm thick. But yea, 30/80 are the radiator thickness. The reason I do 120 * 120 * 80 in the numerator is because fans are square, and the 2.1 million number is cubic millimeters, so you have to multiple all three dimensions of the radiator in order to subtract a correct value.

 

Anyway, a bit of math can answer your questions.

 

edit: Fixed math on the 80mm rad calculation.

I would use 480/560mm on top and bottom. and a 240/280 next to the PSU. Just like Jay's Skunkworks.

I really like to fit as may radiator as I can without make the tube so crazy.

BTW, try to not use 120/140mm radiator. It take a lot of space and make the tube go crazy, and have little performance increase.
