EK Water Blocks unveiled the first pictures of its full-coverage water block for AMD Radeon R9 295X2. It takes a meaty block to cool the 500-Watt dual-GPU monstrosity, which is also the fastest graphics card money can buy. The EK-FC R9-295X2 from EK is one of the few full-cover blocks that feature coolant channels that actually span the entire obverse length of the card. The channel is designed in a way that coolant is distributed uniformly to both the GPU systems, their neighboring memory, and the central portion of the card, housing its feisty VRM and PCIe bridge chip. The block comes in two variants, one with clear acrylic top over the two GPUs, with an aluminum central top; and one with opaque acetal top instead of clear acrylic. The two blocks come in two further variants, clear copper and nickel-plated copper block material. To top it all off, EK appears to either be bundling, or separately selling a single-slot expansion bracket for the card (a carryover from its HD 7990 block).

I'm far from an expert in Watercooling.

But wouldn't it be better if the In/Out was in the middle of the block, so the pressure is even for both GPUs?

Maybe but it would need to be where it is so that multiple blocks/cards can be used in line

Looks like the water flows through gpu-vrm-gpu in a single path so it makes no difference. Restriction causes pressure drop which reduces flow rate and flow rate is what affects heat removal(other than block design obviously). Where in the loop is the pressure dropped doesn't matter, there's only one flow rate in a simple serial loop. And unlike air, water has a huge thermal capacity so unless you're removing a LOT of heat and have a VERY low flow rate the temperature difference of cooled and heated water is very minor.

In reality it would not make a noticeable difference. The flow is so fast that it just gets over all the components at a high enough rate that doing different locations of the connectors on the block itself won't really help much so they mostly put the focus on putting it in an area for convenience.

So its not much of a difference if any.

An echo...? ;)

Now i'm not using Watercooling, nor am an expert at it.

But should't the In/Out be in the middle of the Block? The second GPU is quite far away. Wouldn't it lose flow pressure?

Aquacomputer blocks look 10x times better imo.
