Alphacool NexXxos NVXP-3 GPU Waterblock

Close Look - Alphacool NexXxoS block

The Block Itself

The Alphacool block is made up of a solid copper full cover base that has been milled down to a very nice finish. There is a channel for the water to run over the memory modules and hit the contact area where it is spread out with these channels.

The copper base is covered by an acrylic top, which makes the block very nice to look at. This is sealed by rubber "o" rings and seems to be pretty water tight.

The finish of the base is pretty nice in all honestly. It is very flat and even though the packaging the block came in was pretty un-protective, the block seems to be fine.

It is worth noting that Alphacool say that you should clean off the base with some cleaner. This is good advice and I always do this on any block I install anyway. I used TIM cleaner and the finish came up even more impressive than before.

That looks pretty impressive to me. I also put the block on some glass and found that it was very flat.

The block has inlets and outlets clearly labelled, making it very hard to get the flow wrong.

These are 1/4" BSP and should let a decent amount of water in.

When I first looked at the block I did wonder how it would fit the inlet and outlets, make contact with the RAM AND the GPU. Here's the answer: it is sloped in design.

As mentioned previously - the block does not come with any barbs at all. I am using this with my high-flow 1/2" setup so I acquired some 1/4" BSP to 1/2" Bar connectors.

Looks pretty nice so far - let's see how it performs

Today we take the Alphacool NVXP-G8 full-cover block for a bout of friendly, water-cooled frolicking against EK's best.

Great review mate, I sadly can think of many improvments they could make to the design.Quote

Mr. Smith
Sound methodology and a balanced conclusion.

I'd take the EK over the alpha due to ability to change barb direction... That and it performs better lolQuote

Thanks guys for the feedback, it's very much appreciated as it allows me to refine the process. Is there anything else that you would like to see done in future reviews that I haven't included?Quote
