If you think your CPU is running too hot, I made this quick guide to help you bring temps down without spending a dime. When a CPU overheats, it can throttle hard or even shut your PC down to prevent damage, so it’s worth fixing early. I also cover what “normal” looks like: idle temps vary a lot based on ambient temperature, your CPU, and your cooler, but roughly 30–50°C at idle is generally fine. Under gaming load, I don’t want to see you consistently exceeding around 80–85°C. From there, I walk through five practical tips I use to reduce CPU temperature fast. First, I show you how to drop temps in minutes by changing Windows power settings—specifically setting maximum processor state to 80% (I wouldn’t go lower). Then I cover BIOS fan curves, with the trade-off: more RPM can shave a few degrees, but it adds noise and can reduce cooler longevity if you run it high all the time. I also talk about reapplying thermal paste if your build is a few years old, dialing in case airflow for neutral pressure, and the obvious one everyone avoids—cleaning dust from your fans and case with compressed air.
