I was removing the stickers from my Cooler Master Halo2 fans and noticed that this metal piece is loose there’s no glue residue at all. Does this mean the fan is held in place solely by a magnet? I also took the opportunity to turn off all the LEDs 😅 they distract me; I have ADHD.

It is now blocked on my system, and should be on yours. Coolermaster software is just a virus waiting to happen. Fix your software coolermaster. I've been asking for a year now. Just fix it. Your hardware is kinda ok. Your software bites.
