Why the constant issues?

[RTX3090]

Why does corsair constantly have issues with hardware such as Fans, Commander nodes, and rgb hubs? I've had 2 Ql 120 fans die within a year of building my computer, another fan is about to die soon as well because I can see the red on one of my other fans when it shouldn't have that color on the back side. Noticed one of my top fans not spinning and went to trouble shoot it only to find out that the commander core XT no longer gives power through one of the ports. K100 sometimes freezes making me have to unplug, and plug it back in. Along with a whole lot of other crap. What the hell is up with corsair?
