Portugal , Setúbal.
Hello, mates and watercooling enthusiasts.
I have almost all the parts for my new build, whitch i hope to be the build that brings me more work in custom builds whit watercolling for clients.
Iam aiming for preformance and looks , ill list the parts so ppl that respond to this thread have an idea , while giving me theire personal opinion :).

Case:. Fractal Design Define S.
Mobo:. Asus Crosshair V Formula-Z
MEM :. Gskill Trident x
GPU:. XFX Fury trple dissipation ( but i already bought the EK nikel+acetal and backplate for it, yesterday actualy )
CPU:. FX 9370
Reservoir :. Circular 200mm Modular from Monsoon blood red container colour.
Tubbing :. petg , Blood red from monsoon aswell.
Fittings :. Economy fittings RED , from monsoon aswell.

now for my problem \ doubght , please give me your personal opinion in terms of looks and preformance. iam undecided between 3 CPU waterblocks.

Watercool Heatkiller IV Pro Acetal top:.

Watercool Heatkiller IV Pro Copper\nickel:.

EK Supremacy EVO RED:.

note:. from what i have seen the heatkiller nickel is the best in preformance but it would look like crap in the built and i dont think that it would be a good idea to paint the Nickel top whit plastidip ?
The Heatkiller whit acetal top or that beautifull EK red would match the build perfectly...

Can you guys give me your personal opinion ? :):) pls.

I agree. Those blocks will be within 1-2c difference. I would also agree with Jack on the red EVO. Will match your color scheme.

This is the one I use Koolance 380a , good performance and looks plu durable. Had it a couple years and have had it on and off probably over 200 times. Good solid backplate too which is important.
