CPU Idle Clock, Voltage and Temperature Concerns — Warranty Says It’s Normal?

[Qyueeon]

I wanted to get your opinion on my ASUS ROG Strix laptop’s CPU behavior. ASUs rog Strix scar g18 rtx4090

While idle, the CPU clock speed fluctuates between 2000 MHz and 4000 MHz, and the voltage can go up to 1.4 V. Despite being idle, the CPU temperature sometimes reaches 70°C.

I sent the laptop for warranty service, but they told me this is normal.

Is this really within normal ranges? Does anyone else see these idle voltages and temps on their machine? Any advice or experience would be appreciated!

Thanks!

When I first got the laptop, the idle CPU usage was around 5%, but now it shows about 11% on the main screen.
