Having issues with cyberpowerPC

Hey so I recently bought a gaming laptop (the tracer IV) from my brother. It was 2 years old at the time and is now 2 and a half years old. When I first got it nothing was wrong until recently, why I'm writing this. I noticed that after playing games for about 10 ish minutes my fps would drop drastically from 60 to around 5. I thought these were memory leaks, so I continued restarting it each time. But it kept happening to the point where I started checking my task manager. But everything was fine under the task manager and it was using at most 70% memory. So then I started searching for common causes. When I came across thermal throttling. Which I quickly pin pointed to my laptops fans. Since I realized the fans weren't moving when playing games the I then got a app called HWINFO to monitor it. However inside the app the fans weren't accessible and I could not see them and if they were working. I then looked to see if dust blocked them and restarted. However when restarting the fans turned on and began blasting like they used to when I orginally got the laptop loud and clear. But now I realize they haven't been making any noise at all. I continued researching and tried searching control center in my windows but have no luck the only thing the appears in control panel which has no fan options in it. I went through the whole control panel twice reading everything. But the control center was supposed to be pre installed. And google won't help me anymore and no one else has said anything about this. I might be stupid or very unlucky. But I just want to know do I have to open it up or anything. Again my model is a CYBERPOWERPC a Tracer IV 4070 laptop with 16gb ram, and 19-12900HX specs. If anyone else has had these issues please tell me how you fixed it I'm out of ideas and am starting to freak out.
