Question about my 7970

post #1 of 4
Thread Starter 
I have a Sapphire HD 7970 Dual X. It is the blue PCB version. From what I gather, this is not a reference PCB, so there really aren't any waterblocks for it. Is that right? I'm considering putting it under water (H220 with an i5-2500K), but I really don't want a universal block. Otherwise I would consider running down a reference card. Is all of this right, or is there a good block that will go on this card?

You can find blocks that fit non reference cards, you just need to look up their compatibility list. EK should work

Though it's just speculation based on that chart. By the way, universal waterblocks will usually outperform full coverage blocks, just so ya know.

Really now? I always thought it was the other way around?

Full coverage blocks cool the VRMs and VRAM chip, so they have that vantage, but they have a directional flow lane based heatsink over the GPU.

A good quality universal GPU waterblock like the EK-VGA Supremacy has focused flow over the GPU. This removes heat from it much better than a full coverage block. If you do go the universal route you need to make sure to put heatsinks on the VRMs and VRAM chips and be sure to have adequate airflow over them.

Developing a full coverage block with focused flow over the GPU would be a nightmare to design, and would also be a LOT more restrictive. Oh, I should note that focused flow universal coverage GPU blocks will also be about as restrictive as a CPU block.
