CPU fan rattling and computer is laggy and choppy
So as I do every 2 months is clean the inside of my computer tower and today after I finished cleaning, I turned on my computer to make sure everything was working. I immediately noticed the rattling coming from the CPU fan and bios gave me an alert about the cpu reaching 190+ Fahrenheit so I turned off the pc again immediately to cool it off, after a while I turned it back on and everything is laggy, my cpu is at average temperature I can still hear the fan rattling but it’s running so I figured it would still be doing it’s job cooling it down. And I know it can’t just be the fan that’s messed up, simply left click and drag on the desktop highlight is laggy, does anyone have any clue to what’s happening? Is my cpu just half way there now?
