I still like the ugly ones. Reminds me to old computer from the 90s.

Chromax just launched, so I might disagree that they're all still ugly

Aurora, due to its PSU mounting very close to the CPU heatsink needs a slim model like below; before buying a slim cooler, check the heat TDP rating spec on it relative to whichever Intel CPU you choose so it can handle the TDP heat rating of the CPU

These types can be an upgrade over the whimpy stock Intel kooler they sold u, but not as good as a liqwid kooler

You can also try using Noctua fans. These fans are powerful and silent. The only drawback is their ugly color.
