Finished Looks
Overall, the AQIRYS HYDRA 360, while mostly a high contrast design, will stand out depending on the system due to the stickers on the fan. The color of the AQIRYS logo is striking with its violet and blue hues. Still, it's not an unattractive design since its simplicity means it should fit in most build themes beyond the fan logo which can be easily dealt with by either removing them carefully or just coloring them black to give the cooler a stealthier look.
As for memory and graphics card clearance, there were no issues on either platform.
The individual ARGB LEDs in the fan hub are easily visible and standout from an angled look but from the front they tend to disappear, so depending on your setup the LEDs themselves will either be very visible or not at all. Still, the lighting was bright enough to do the job without being extreme with illumination easily extended across the entire fan surface. I did notice occasional flicker when switching between static colors, but for rainbow or other effects everything was smooth.
