Best Water Block?

[Daniel Johnson]

Ok, so I'm using an ASRock X99 LGA 2011-3 Extreme 11 motherboard and an i7-5960X CPU.
I'm being pulled between these three waterblocks:

1. EK-Supremacy EVO - Full Copper (Original CSQ) [3831109800164]

2. EK-Supremacy EVO Elite Edition - Intel 2011-3 [3831109800324] with EK-TIM Indigo Xtreme ETI

3. EK-Supremacy EVO - Full Copper (Original CSQ) [3831109800164] with EK-TIM Indigo Xtreme ETI

I know that copper has one of the highest thermal conducitivities, far greater than nickel, making the full copper block very appealing, but then I realized that the elite edition block come with EK-TIM Indigo Xtreme ETI which is apparently the best thermal paste available. So I wasn't sure...
Now I'm thinking, what if I combine the best of both worlds and use the full copper block with the EK-TIM Indigo Xtreme ETI?

Which is best?

And would de-liding the i7-5960X, applying better thermal paste like Coolaboratory liquid pro onto the die, and then reseatting the CPU allow for lower temps, even just 1 or 2C lower?
