The ePSA diagnostics passes. This Inspiron G5 5000 is fine. Intel states that the maximum temperature allowed at the i5-10400F processor die is 100°C. Gaming will cause all system fans to ramp up. The idle temperatures are also fine. When installing a game, change the install directory location to point to the 1TB D drive. This way you will not fill up the 256GB C drive. In your case, this may involve uninstalling the game, then reinstalling it on the other drive.
My pc just seems unusually loud. I am also having a problem with cpu temperatures. At idle it is 43 degrees. My bios version is 1.0.5. I played a game for one hour and my CPU was 90 degrees. I checked via AWCC.
