Help me? My pc is overheating and i have fps drops when playing Fortnite?

Hello guys I have this pc but it quickly gets overheated and then the game is over. What should I do?

msi Gaming Pc Intel® Core ™ i5-8400 processor (up to 4.0 GHz), hexa-core

8 GB RAM, 1.128 TB storage, USB 3.0

NVIDIA GeForce GTX 1060 6 Gb graphics (6144 MB)

How about cleaning him up?

Is it clean Got air? Unfavorable airflow?

Run it without a side panel

It doesn't work

More important than you installed components would be to find out what type of housing you have, how many fans and where it is located. A photo with the side wall open would also be helpful.

Did you overclock something?

Then I would change the thermal paste.

Where should I get that. Send a picture

You could attach the picture here or just upload it to an upload page and share the link here. What about the rest of my questions? So it is difficult to help you.

Another question is what kind of temperatures do your components have? So motherboard, CPU, GPU, Ram…
