7970 Waterblock Advice Needed (Reference)

post #1 of 11
Thread Starter 
I have recently come across a Diamond 7970 reference card and would like to incorporate it into my WC loop. I have my eye on this block to match my Raystorm CPU block:

How does a block like this add up against a Heatkiller (or any other blocks for that matter). Any better suggestions are welcome!

I prefer ek blocks because they have great flow and they cool the vrms better

XSPC blocks are great; performance wise, it will be pretty close to other blocks. The thermal performance will all be within a few degrees, really. The only 'better' suggestion I have is the EK Nickel block; the clear acrylic top looks fantastic to me. I love being able to see the coolant across the block, but as for being a better block, it is purely aesthetic. Get whatever you personally looks best, really; performance differences are negligible at best.

The XSPC 7970 blocks only passively cool the VRM's while most other FC blocks feature active cooling. The build quality of the XSPC block is also less refined than the other brands like EK, Heatkiller, Aquacomputer.

Alphacool NexXxos blocks aren't bad at all, and i also like EK and XSPC. The only advices would be to get the NexXxos v2 (if you go with Alphacool) as it has active VRM cooling, and avoid the nickel-plated EK blocks (i do not trust their plating).

Just be aware that the Alphacool Nexxos V2 is not a 7970 water block. It is designed for the 7950 PCB

I have a Watercool HEATKILLER GPU-X³ 79X0 for my HIS card and the build quality is top notch. It also has active VRM cooling and as Jakusonfire said the EK is only passive cooled.

Here is a thread by SonDa5 comparing the EK and the Watercool that might help. If I had to buy again I would most definitely by the Watercool again.

XSPC generally make very good and competitive blocks. Their 7970 block however is a dud. It's one of the worst performing fullcover blocks on core temp, and it has no active cooling on the vrms. It looks great with the new look, but that doesn't change that it's a dud in their current lineup.

Thanks for the tip! I'll be going with a Heatkiller block for the reference 7970 smile.gif

Top choice, look great and very well built. I'm probably being no help here but I hope it confirms you're decision tongue.gif
