Overall, the ZADAK SPARK AIO 240 actually matches quite well with the test system's MSI Z370 Gaming Pro Carbon AC motherboard. The pump design fits the angular design of the MSI motherboard's heatsinks. Meanwhile, the rest of the cooler kind of blends into the background because of its mostly black color scheme.
Memory and graphics card clearance is fine with no issues to speak of.
The ARGB LED lighting is where things fall apart for me. I have two samples and both exhibit the same behavior. Neither likes my test system's motherboard. To rule out the test system, I used my personal system, which has the same board, and the problem persisted. The ARGB LED lighting tends to flicker when plugged directly into the motherboard, with odd colors and other issues popping up. Using the included ARGB controller and plugging it into the motherboard header helped alleviate the problem, but both the flickering and odd syncing behavior were still noticeable. While it could just be my particular motherboard, I did try older versions of the Mystic Light software in addition to MSI's latest version to no avail. This could be a problem on MSI's or ZADAK's end, but it wasn't a pretty sight regardless. With that said, when set to a solid color, the flickering wasn't as noticeable, and the lighting effects were pretty good—definitely not unique or amazing, but not bad.
