Question Regarding Airflow of Acer Predator Helios 300 (2019)

AFN

My laptop's performance has been degrading greatly and I'm getting 92C temperatures playing any game (like, really, any game) and 50C+ idle temps.

I am assuming it might be an issue of airflow. Turning my fans on max, they do seem to be working (I can tell since they're too loud). The flow I can feel:
- Flow from the right vent
- Flow from the left vent

The flow I can't really feel
- Flow from the back (none at all)
- Flow from the bottom (I would assume this is normal)

Honestly I can't remember if there is supposed to be airflow from the back but common sense tells me there should. If there should, should I just open it up myself to see what's wrong (maybe clean fans?) or get it fixed somewhere?

Here are detailed specs if needed:
Predator PH315-52
Intel Core i7-9750H
Nvidia GeForce RTX 2060

I have the same laptop and yes the hot air should exit from the rear vent and when on max fans should exit quite aggressively. I suspect a dust accumulation. Things you can do:

1. Open up the laptop and clean the fans and the radiator.
2. Repasting is a sure shot way to reduce temps. If you haven't repasted your laptop ever it will greatly help to reduce temps.
3. Use something to give clearance between the laptop and the floor.

Here's a link on how to open up, clean and repaste your laptop: https://youtu.be/6Kl-uiULkVQ

NOTE: DON'T TRY TO OPEN YOUR LAPTOP IF YOU HAVE THE WARRANTY STICKER ON ONE OF THE SCREWS OR YOU ARE NOT AT ALL CONFIDENT OF DOING SO. IF YOUR LAPTOP IS IN WARRANTY TRY TAKING IT TO THE SERVICE CENTER. ALTHOUGH OPENING UP THE LAPTOP CAN BE A BIT INTIMIDATING AT FIRST BUT ITS QUITE EASY.
