In a word, no. It's common for users to think that a light workload is their "idle".
What is your ambient temperature?
Is "idle" really
idle? Probably not.
What is your % CPU Utilization in Windows Task Manager at "idle"?
Here's the definition: "idle" is minimum activity at 1% CPU Utilization. This means SpeedStep, Speed Shift, C States all power saving features enable in BIOS, and undisturbed in Windows with "hands off". Windows Power Options set to "Balanced", no programs or screen saver running, and off line. No Folding or SETI or DropBox or "tray-trash" running in the background, and just
1% CPU Utilization under the "Performance" tab in Windows Task Manager.
If you're really at "idle" then here's what it should look like:
Since Windows has dozens of Processes and Services running in the background, it’s
normal to see rapid and random Core temperature “spikes” or fluctuations, especially during the first few minutes after startup.
Any software activity will show some percentage of CPU Utilization in Windows Task Manager, where unnecessary Tray items, Startups, Processes and Services that contribute to excessive spiking can be disabled.
