The radiator comes packaged in a sheet of bubble wrap, and then there is another plastic sleeve over the core to ensure it is completely pristine and devoid of dust out of the box. As we saw before, the incredibly low-profile nature of just 20.5 mm is the main selling feature of the XSPC TX radiator series—over 5 mm less than competing options from direct competitors as of this time, it is nothing to scoff at. Helping further with case compatibility is a width of 125 mm, which is barely over the 120 mm of the fans themselves, and the end tanks are also not huge, which helps get the TX360 to within 400 mm in length (398 mm, to be more specific). The radiator also has a matte black finish on the frame with a light coat of black paint on the fins. This helps match it with just about any color scheme for your watercooled PC you may be thinking of and lets the other components shine against the black background. The XSPC logo, in white, is located on both of the longer sides, as seen above.
The fan holes are threaded perfectly and perpendicular to the radiator surface at a standard 15 mm apart to coincide with fan holes on modern cases and radiator mounts. XSPC has offset the coolant tubes here such that, even if you use longer-than-appropriate screws and do not know when to stop, the screws will only hit the fin stack and not pierce any coolant tubes. This means there is little room for the radiator to leak due to user error, and XSPC also gets away with not having to have screw shields, which also helps keep costs low. The end tank on one side has two threaded BSP G1/4" ports, again without any complaints, that come with dust caps on them, which you should definitely not use as stop plugs in case you want to clean out the radiator prior to use. We can clearly see the brass end tank in use here, with brass tubes and copper fins making up the rest of the radiator as far as material composition goes. This is a single row U-flow radiator with inlet on one side and outlet on the other, but no specific preference over which has to be which. Given the nature of the radiator's low profile, I can understand the absence of more ports here more so than on other radiators.
The radiator core is where XSPC spent most of its time, using thirteen coolant tubes, six tubes in one direction and five in another, to offset the tubes as seen above. The tubes are also 1.5 mm in diameter on average, which is on the smaller side of average as well and helps with having more fins in-between. As it stands, the radiator is rated for ~132 mL coolant capacity, so account for this when estimating how much coolant to have for your entire loop. Though also lower in height than average, the fins themselves are of the splitter type, which helps add active surface area for heat dissipation. They are dense at 22 FPI and lightly louvered for a performance balance across the airflow spectrum XSPC designed this radiator for.
