Dragon center and Core Temp stayed very low, yet the system ran on a high frequency. My computer didn’t lag or become unresponsive, but I was worried it might stop working completely.
In practice, most monitoring tools struggle to accurately track idle clock speeds due to how modern processors manage power. Instead of lowering performance during inactivity, newer CPUs often shut down unused cores completely and wake them up instantly when needed (Race-to-Idle). This can make idle times seem unusually fast—sometimes even higher than when the system is under load. However, some software like HWiNFO can estimate a more realistic "effective" speed by factoring in idle time, revealing details such as: my laptop right now has only three browser tabs and background apps open, yet Core Clocks display around 4.9–5GHz. The key is the "Effective Clock" readings, which reflect actual usage patterns. What’s happening is that cores stay mostly off but keep high clock speeds to finish tasks quickly before powering down—similar to how you operate. Overall, this behavior isn’t typical for your setup, likely due to a bug with 100% CPU usage detection, especially on newer Ryzen models.
