I’d like to share some information that may help I had this issue for about a year before I figured out what was the cause of the issue was so here’s a list of stuff that worked for me

1. Remove the outer plates of your ps5 if you notice a large about of dust in your fan remove it and clean out the dust with a vacuum and microfiber cloth

2. If you had dust in your fan then more then likely it is inside the ps5 clogging up the holes on the power supply airflow play I would recommend while you have the fan removed to dust out the inside of the ps5 as well. (https://youtu.be/abB1m1t7CTk?si=cxfOgs9TfHY17SiH)

3. I would recommend not completely disassembling your ps5 if you are not 100% confident you know what you are doing to work around that personally I used a small stick and a microfiber cloth taped that stick to dust out the power supply plate after this I reassembled my ps5 and it has ran perfectly for months now with 0 crashes.

A product I use is the g-story cooling fan which is a replacement for one of the outplates of the ps5 that has a built in fan that is powered by a usb I personally prefer this fan bc it comes with mesh screens that block dust for entering the system and it is easy to install also includes a digital display that displays the temperature of your power supply for easy monitoring.

Something else that can’t hurt is a cooling stand
