HP ProDesk 400 G4 SFF
Microsoft Windows 10 (64-bit)

Ok, so I bought this almost new HP ProDesk 400 G4 SFF with i5 7500 and it works just fine while doing office work and so. Even on Youtube on 4k video resolution the temperature doesn't exceed like 60C, but when I open any any game, like Half-Life 2 on default settings and the temperature goes to like 80-85C. It has fabric cooling problems I see that, but I added a second fan at the end of my PC, and it helps a bit, for like 2C less. Then I tried searching for fan speed options to speed it up, but I found only where it said that fan speed is now 70%, but it doesn't feel like it, it feels like it is on 20% all the time. The bios is so simple that user can't control the fan speed. I think even that HP didn't test the airflow with their cooling system of this set of pc-s. I didn't find a solution online that's why I am here to search for an answer. Someone please help, and I know that people have the same issue on this pc as me.....
