It sounds like your CPU is running at high temperatures, reaching 80-90°C and running heavy-duty games at 70-80°C constantly. This could potentially be a problem with your computer's cooling system. There are a few things you can do to help lower your CPU temperatures. Firstly, make sure your computer's fans are running properly and are not blocked by dust or debris. It's also important to make sure that the heatsink and thermal paste on your CPU are properly installed and functioning correctly. Another thing to consider is upgrading your computer's cooling system. You could install additional fans, upgrade to a better CPU cooler, or even consider liquid cooling. It's also possible that there may be a software issue causing your CPU to run at high temperatures. Make sure your computer's operating system and drivers are up to date, and consider running a malware scan to make sure there are no malicious programs running in the background. If you're still experiencing high temperatures after trying these solutions, it may be worth consulting with a professional to diagnose the issue and determine the best course of action.
