Watercooling Advice

[Burty117]

Hello to the poor soul reading this.

I've built lots of PC's in my time, I've never dabbled into the realm of custom watercooling loops though, until now.

The case is the NZXT H500, I plan on using the EK-KIT P280 to cool my CPU (De-Lided 8700k) and GPU (980Ti but will be upgraded to whatever the next Ti Nvidia release). My question is, will the single 280 Radiator be able to cope with both? The CPU dropped 15-20C just by De-Lidding it but the GPU just naturally gets very hot. Should I consider adding an extra Radiator? The only space for one though is probably a single 120 as the exhaust which isn't ideal. A top mounted 140mm is out the question as there isn't room.

Any ideas welcome

Interestingly, I can put my exact config into the EK Custom Loop builder on their website and they have this to say:

Based on your choices we estimate the heat load (of the liquid cooled components) to be 430W.

Therefore we recommend the use of EK-CoolStream CE 280 (Dual)on front and EK-CoolStream SE 120 (Slim Single) on back of your computer case.

So basically, add an extra Radiator, got it. That's fine, next question.

What's the recommended way to plumb it all in? Do I go:

Pump/Res > Radiator (280) > Radiator (120) > CPU > GPU
or
Pump/Res > CPU > Radiator (120) > GPU > Radiator (280)
