Random clicking sound

So i got a new ps4 slim and it works fine but because of dumbass roomies it has now been switched off randomly by plugabout 3 times in a month,i have since moved it from a place where they can access it to where i can access it only,it makes a random tiny sound from a different spot every 10 mins that sounds like its settling in,it also makes a double clicking noice when it goes into rest mode,these sounds are extremely unnoticeable and i only noticed it while sitting next to it.Sometimes it makes no sound for an hour or two,am i just being paranoid or is something wrong
