My custom-built desktop is large, but the Corsair H100 RGB AIO liquid CPU cooler doesn’t actually fit comfortably inside, so it sits on the top of the case. It looks good there, and the pump and dual 120mm fans keep my system cool. Unfortunately, for unknown reasons, my cats occasionally compete with one another to see who can sit in the stupidest place. As I type this, one is sat on the back of my office chair and another is curled up comfortably behind one of my monitors.
It is not unheard of for them to squeeze into the space on top of my PC case, essentially jamming their furry bodies against the fans. They also find the spinning of the blades entertaining, which isn’t great either.
