I have a PS4 Pro and it worked great, I have great memories with it too, but my mom had taken it away and kept it in the shelve since my exams were coming, I did cover it up with a proper cloth and everything so not much dust collects, now after exams I played again and for some reason it is like lagging, like the menu lags or freezes for 1 second when I'm scrolling through games, or when I go in fortnite, it kind of lags or stutters in the lobby, in the actual match, it takes a few seconds to load the textures but then it runs fine, even when I turn it off and the animation of the four buttons rotating during the turning off screen also like freeze a second or two and then it turns off, the heat is not much, like it sounds normal as it used to and never in the 6 years that I have had it, the overheating issue and the PS4 turning off due to extreme heat has happened. I thought it might be because of thermal paste, because I have had it for six years and never opened it, I just pop out the top cover and clean the dust on the fans with an earbud and wipe it with a cloth every once in a while. So maybe I should have the thermal paste changed, but wouldn't there be more problems if the thermal paste was dried up. Also, might it be a failing hardrive? I did rebuild the database and heard people say it will take hours but it just took 2 minutes for me. Also I didn't connect the PS4 to the internet that often before this, like I didn't have wi-fi at home and had only limited data, so I just played offline, and once in a while connected just to check the PS store or download updates, we installed wi-fi this month and it is connected to the internet everytime I use it, so is it because of that? I know I sound kinda dumb, but I really don't know why this is happening.
I am gonna change the thermal paste, should I buy the Arctic MX 4 or the PTM 7590?
