XSPC Razor Neo GTX 1080 Ti Waterblock Review

If you are thinking about delving in water cooling your high end NVIDIA GTX 1080 or 1080 Ti video card, the XSPC Razor Neo is certainly worthy of being on your short list. Outside of its incredibly good looks, Frag Harder Disco Lights, and easy install process, does it work well when it comes to overclocking and cooling your GTX 1080 Ti?

XSPC Razor Neo Waterblock Assembly

Of course, the one that must be done before you install your Razor, is that you have to remove your stock cooling device. The Razor block we have is specific to the NVIDIA Founders Edition GTX 1080 Ti and GTX 1080. Below you can see the process of breaking down the Founders Edition cooler.

After we get that all broken down, we get to the fun parts. Let's put all of this together! The video below goes through a few steps that you don't truly need to do at home, however there were some things we wanted to check before we started testing temperatures and clocks.

While you do not have to, I would suggest that you surely check the GPU and coldplate mating surface before making your installation permanent. If you do not have a good contact patch, all your money and effort is simply wasted, and we don't want that. The odds of these mating surface being "off" is extremely small, but again worth checking. What is most important here is making sure that your TIM application is good. We use Prolimatech PK-1 TIM. Your mileage may of course vary depending on what kind of TIM you use. Should you wish to go with a liquid metal TIM like Coollabs Liquid Ultra, I would highly suggest that you insulate the surface mount devices around the GPU die with something. I like to use Red RTV Silicone gasket material. It is easy to apply and easy to clean up, and is not permanent should you wish to remove it later. We got great mates with the Razor block as shown in the video below.

Second is that we wanted to check our thermal pads for contact and compression. I have used kits in the past that included pads that were of the wrong thickness, and if your thermal pad is not touching the block or the IC, then it is likely doing more bad than good. All the pads included with Razor worked perfectly and gave us good mates.

The instructions for the Razor block are very well done and straight to the point. No instructions were included in our box. There is however a product manual online for the previous Razor RGB block which is a bit different in construction. The build process however seemed to be identical.

Update:. The Razor Neo manual is now available online and paper instructions will be shipped with retail blocks.

If you are wanting to install the Frag Harder Disco Lights that are included with the Razor, you will want to make sure and install these BEFORE you fix the block to your video card. While it is not impossible to install these afterwards, it is not an easy process at all due to how the mount points are not easy to reach.

Coolant Flow

Before we got all of the air out of our system, I shot a quick video that will give you an idea of the flow paths through the Razor block.

System Installation

The XSPC Razor block is very heavy as you might expect from a sizeable piece of copper. One thing you need to be aware of it the weight of the card once assembled. It will very likely need to be supported if you are using a typical tower case.

As you can see from our scale, our card weight is coming in at 1427 grams, which is a bit over 3 pounds. I personally would not leave this card unsupported and "hanging" in the slot.
