Watercooling, how much rad estate do i need ?

[Skavikeng]

Hi guys !
I am new to this whole watercooling scene. But i want to upgrade
from AIO coolers on both my cpu and gpu and just run a custom single loop.
So the question is, what do i need ? and how much do i need ?

I know this is a complex question, but i have tried my best to read on the web, but i just need someone to tell me if this is going to work or not. i want decent cooling, but i also want silent opperation. when it comes to flow and head pressure i understand what they do, but i am having a hard time implementing it into theory so i can calculate if the pump is going to be strong enough or not.

System components that will be cooled:
• i7 6700K - 95w tdp
• AMD R9 295x2 - 500w tdp

So the parts i have mentally put together is:
• XSPC Raystorm pro - cpu block
• EK-FC Acetal + Nikkel R9 295x2 (only gpu block i could find)
• 2x HW Labs Black Ice Nemesis GTX 420 radiator (this can change depending on case)
• Aqualis XT 450ml res
• Aquastream Ultimate pump
• 6x Thermaltake Riing14 rgb fans in push config.

Is it overkill ? or how much cooling do i really need for a single loop with 6 - 700w tdp,
and to be able to run it fairly silent ? will the pump be able to do it ? since i like its monitoring and controlling capabilities.
Ambient room temp wil be around 22c
I am thinking about building in a BeQuiet Darkbase 900 when it is launched.

Hope this is not a total miss on my part by posting a question about liquid cooling.
But i just cant wrap my head around calculating it my self. Most probably because i live on a small arctic island with 10.000 ppl total So dont have anyone to teach me irl.

The 295 can be a hot card but as with all GPU's they love a bit of water.

You could 'cope' with a single 360 but if you want quiet with low spinning fans the a 360 and a 240 would work well.

Just remember when it comes to the CPU that if you rage the volts too much even your water wont keep it in check and with an overclock on it I wouldnt be surprised to see 70c

Yeah the 295 is running a bit hot with the standard AIO cooler, so i would like to give it more headroom in regards of radiator space.
And price wise there is not too much difference between a 360 and a 420 rad.
In the spec sheet of the Darkbase 900 it says it is room for a 420 in the top and a 420 in the front. But if they both will fit i dont know yet And i would preffer 140 fans over 120 fans.

Have not received the cpu yet, it arrives on friday so what temps to expect i dont know yet.
I have been using a AMD 1090T for almost 6 years but my motherboard died a few weeks back, so had to grab some new components. Have all components here on Friday
Grabbed a EVGA z170 FTW mobo, 6700k cpu and 16gb with Avexir blitz ddr4 3000 ram.

But for the pump, you dont think there will be any issues with the setup i have in mind ?

with 2 x 420s then I think you will be fine. Remember, in WC there is NO such thing as Overkill - the more rads you can cram in the better. You can use slower RPM fans etc.

The _Governour is SO correct about never having enough rad space. Heck I own a MO-RA3-420PRO!
