I'm new to building PCs and had this system assembled through a boutique builder a few years ago. Recently I've been playing more demanding games, and after about an hour the computer makes my bedroom noticeably hot—especially with games like Cyberpunk 2077. I'm concerned that the heat could damage the system, although I understand gaming should raise component temperatures.
The system has Windows 11, an AMD Ryzen 9 5900X, 32GB of DDR4-3200 memory, an MSI Pro B550-VC motherboard, an AMD Radeon RX 6650 graphics card, a 700W 80 Plus power supply, a 1TB Intel NVMe drive, and an iBUYPOWER Slate Hako MR case. The BIOS is listed as version I.20.
While testing Palworld, I saw a temperature around 78°C after only a few minutes. I also captured sensor information with HWiNFO64, but I'm having trouble understanding all the readings. Are these temperatures safe, or should I improve the cooling or replace the case?

A hot room does not automatically mean the computer is overheating. The system is converting electrical power into heat and exhausting it into the room, which is exactly what should happen. Modern CPUs and GPUs commonly operate somewhere in the 60–90°C range under load, depending on the part and cooling setup.
The case may have mediocre airflow, particularly if the front panel restricts intake, so a better airflow-focused case could lower component temperatures and fan noise. However, it will not make the room cooler. A gaming PC using several hundred watts works much like a space heater: nearly all of that power eventually becomes heat in the room. Improving ventilation with a window fan, an open door, or a room fan will help more with the bedroom temperature. Also make sure the case filters and heatsinks are clean and that the fans are pointed in sensible intake and exhaust directions.
The most useful information here is the actual CPU and GPU temperatures, especially their maximum values while gaming. HWiNFO64’s Sensors window can show CPU package temperature, GPU temperature, and hotspot temperature. A reading around 78°C during gaming is generally normal and not dangerous, though you should check the peak rather than a brief current reading.
I checked the sensors and saw about 78°C after roughly five minutes of Palworld. I’ll let a demanding game run longer and pay attention to the maximum CPU and GPU readings.
That makes sense, although the room gets hot enough that I start sweating while sitting at my desk. I may have been interpreting the amount of heat in the room as evidence that the components were unsafe.
