You're supposed to change the liquid at least every 6 months, and... it can evaporate entirely.
Have fun with that!
I'm the lazy kind of person that likes to just build a computer and the next time I open up the case only being either when I'm upgrading something or something has went horribly wrong. So, needless to say... I'm not one of those weirdos that likes cleaning their computer every week. What is wrong with them!
So yeah, I don't like having to do something to my computer on any kind of regular basis lol.
