Phanteks G1080 GPU Water Block Assembly and Flow

Phanteks recently sent us its Glacier series water block for our Founders Edition GTX 1080 Ti. We take you through the full process of getting it installed. We check out the mating surfaces of the GPU, capacitors, and MOSFETs and show you just how well it all fits together. Then finally we show exactly how the coolant flows in 4K!

Phanteks Glacier G1080 GPU Water Block Assembly

This marks our second GPU water block that we have brought in for review, with our first being the XSPC Razor Neo. Given that AMD and Intel are bringing more cores to the desktop, and given that many of us like to overclock those cores, many of us will surely be finding ourselves moving to custom water cooling loops as many AIOs and air coolers on the market are just not going to cut it. And if you are going to be water cooling, there can be a huge upside to adding your high end video card to the loop. Who does not want dramatically cooler video card operating temperatures and higher boost clocks?

The Phanteks Glacier G1080 GPU water block is specifically for the NVIDIA GTX 1080 and GTX 1080 Ti, however Phanteks does build blocks for cards from ASUS, Gigabyte, MSI and others.

As you can see in its final form it is an impressive piece of hardware.

Before you get to installing your new GPU water block, you of course have to remove the original equipment. You can see our full video here of what it takes to strip your Founders Edition naked.

Below is the full process that we had to go through to reliably get our Phanteks G1080 attached to our 1080 Ti properly. We did run into a few hurdles that we point out in the video and we we surely discuss these in-depth in the full review, which should be published this week. As noted, we take our time and show you just how well the GPU mates to the block and then we go through another install process to show you just how well our thermal pads for the VRAM, capacitors, and MOSFETs mate as well. Not everything was as perfect as we would have liked, but it is up and running on the test bench tonight showing very good results. Our G1080 unboxing video is here should you want to see it unmolested.

Phanteks Glacier G1080 GPU Water Block Flow Pattern

The last time I shot a flow pattern video, I literally did it as a second thought with my phone after I had already started to pump coolant through the block in order to leak-check and get all the air out of the system before testing. More than a few folks really liked that so I decided we would do it again, only better. With air bubbles in the system, you can see exactly how the coolant flows through the block. This time around, I set the camera up and got footage from the moment we started it up. You easily see exactly how Phanteks has designed the G1080 to flow coolant.

The G1080 is a directional block meaning that it is designed to flow in a specific direction. Once the coolant enters it is immediately dispersed directly onto the microfins that cover the GPU. From there the coolant flows two directions to reach the VRAM and VRM modules. If nothing else, it is fun geek stuff to witness.

We are pulling data now and the full review will be published this week.
