  1. So basically they lost in what was meant to be their niche of static pressure across the board to a cheaper rgb fan? 😂. Even more embarrassing is in Australia where these are about $65 aud where the shark’s have dropped to $25. Either way ur testing is invaluable for these more niche products especially, cheers.

  2. Hi!
    Thanks for the very cool and high-quality reviews, no one else does that.

    I want to ask you to test noctua nf-a14, a new generation model will be released in the 2024q1, it would be cool to compare
