Which radiator for my config ?

post #1 of 8
Thread Starter 
Hello,

I'm new to watercooling, i've read some guides but i've a little question.

Which radiator should i choose for a i7 6900k + GTX 1080 (OC planned), i've a Corsair Carbide Air 540 so i can place a 360 and a 280mm radiator,
i'll go for a 360 slim (SE) but i'm affraid this should not be enough, can you confirm ?

Is the thickness of the radiator change a lot ?

Btw is the EK-XTOP DDC 3.2 PWM Elite is enough too ?

Thank you !

Usually the accepted method is at least 240mm per component. However with things becoming more efficient thats out the window lol.

Me personally i would do a 360 (non slim if you can) and add a 280 to get very very good temps. A 240/280mm dissipates about 200w for a 10°C water delta temp above case temp, which is pretty much average. A 360mm wil dissipate about 300w for a 10°C, this is also very dependent on the fan you use, the speed, whether its push/pull.

Depends if youre going for quietness or lower temps. And yes a DDC 3.2 is plenty.

Hmmm for now i'll go for a PE 360 (https://www.ekwb.com/shop/ek-coolstream-pe-360-triple) in a first place and maybe add a 280 if the temps is not good enough

For the fans i plan 3 noctua 120 pushing controlled with rehobus

Is the DDC 3.2 is quite ?

Actually i have one noctua 120mm at 100%, 140+150mm noctua pwm with silent adapter, two noctua 140mm at 80% and it's always powered on, i sleep aside the computer, it's okay

Yea there pretty quiet, i have a D5 and i hear the fans over the pump. Idk how the DDC is but from what ive seen on the forum the D5 is quieter but its all personal preference.

Thank you !

A 280mm rad in the roof of your 540 would do an excellent job at cooling your CPU and GPU. thumb.gif

We have a nice kit that has a 280 rad and all you would need to add is your GPU block and 2 more fittings.

EK-KIT P280

Extra fittings needed to match the kit : EK-ACF Fitting 10/13mm - Nickel

I'll go for a custom with hard tubing, btw, is the performances change with the diameter of the tubing ?

Oh ok biggrin.gif

Tubing size won't affect your temps and/or performances.

Even if you're going custom, I still recommend you the 280mm rad. thumb.gif

The surface area of a 360 is larger than that of a 280 (432cm2 vs 392cm2). The DDC isn't super quiet and generates quite a bit of heat and vibrations (at 40% it's non detectable though). The diameter of the tubing should have no detectable performance difference.
