Unboxing and Overview 2

XSPC makes sure you get the product in perfect shape with a bubble wrap cover and then a vacuum sealed plastic wrap over the GPU block as well. Once removed, we see a GPU block that looks a lot more like the short-lived Blade than the Razor, except with an update to the top. Instead of having a full cover aluminum face plate over the acrylic middle section, XSPC has decided to cut the aluminum to fit over the acrylic which gets a polish as well thus allowing the coolant to be visible as it passes through the block. This is an update coming along with the Raystorm Neo CPU block announced recently, which also has an acrylic top over the microfins to go along with customer feedback.

There is an XSPC logo etched into the acrylic top, and the aluminum face plate retains the brushed finish. The other big change is with the I/O port terminal where we now have a much smaller footprint version that juts inwards making this more of a two-slot solution but takes up no room past the height of the block allowing for increased compatibility in SFF cases. There are only two ports now, which is a shame but understandable, and XSPC designed this with rotary fittings, angled or otherwise, in mind. Two of their rotary 90° fittings fit just fine, so aside from the massive Koolance QD4 fittings you should be good as far as port distance goes.

XSPC has never gone with plated copper cold plates, and instead prefer to have a clear coat on bare copper instead. It delays oxidation until the clear coat layer wears off, which is more than a few months in a standard air-conditioned house with ~70% Rh if my living conditions are anything to go by. There are raised sections as well as cutouts to account for contact with multiple components including memory VRMs and chokes, and the cold plate does not have a mirror finish applied via polish. Neither does it extend to the full length of the top and thus there will be some cooler mounting holes in the PCB that will go unused.

As always, disassembly was done post-testing. It requires the removal of every single screw on the front and the four on the back holding the I/O port terminal in place. The screws use a hex 2.0 mm head, for those interested, but you will likely void warranty doing so. Once done, we see the port terminal has two circular O-rings to prevent coolant leaks there, the aluminum face plate is fairly thin as before, the acrylic top is only polished in the visible section and there is a large O-ring gasket around the cold plate to prevent leaks as with any other GPU block.

Examining the fins over the core area, we see there have been some changes here. The Razor RGB (left) has more fins (38) that are thinner (350 microns) relative to those on the older Razor (26 fins, 500 microns thick). The fins on the Razor RGB are also longer as I realized after disassembly, and re-assembly, so I do not have a quantification here. XSPC has new tooling in place for this, with the fin length being limited by the cutting disks used where any further and they may break off. Either way, all other things being equal, I anticipate a higher pressure drop but potentially also better thermal performance with the new design.

Let’s take a look at the installation process now on the next page.
