I took my macbook pro to apple today because as I've said it's getting super hot and slow and crashes regularly and from advice on here I downloaded a program which seemed to suggest my fan wasn't working (00rpm) and I haven't heard the fan for weeks. My friend spilled water on my laptop a few months ago (this is when this all happened). I didn't tell apple.. but they ran tests and said EVERYTHING is fine, checked inside, said that was fine. They said the apps I downloaded to check fan won't have given correct results. BUT my laptop is not working properly They said it'll be software not hardware.
