Weird CPU temperatures/Is this normal?

I just noticed recently how my laptop's idle temps seem to be higher than normal, especially when plugged in even when usage is lower than on battery. They also spike and drop like crazy on idle too. Here's a picture of the temps 30 minutes after boot.

    So that sharp spike at the beginning of your graph is most likely your laptop coming out of sleep or Predator Sense starting up.

    For example, when waking my laptop I get a spike of temperature from 33 C to 74 C then immediately back to 33 C.
    Considering the laws of thermal dissipation given the size of my unit... that's physically impossible. The system is merely reading voltages and basing the temps in combination with the temperature.

    You're only real concern should be max temperature.

    I do have a Throttlestop upload pre-configured that helps govern the aggressive nature of these CPUs you could give it a go.

    Thanks for clarifying. I guess what I'm trying to figure out is why on battery temps are lower but have high usage compared to a charging's higher temps and low usage. Max temps never go beyond 95 as far as I can remember. I use XTU to undervolt currently but will check out the link.

    At 95 C your CPU will "thermal throttle" meaning it will lower its clock speeds to maintain a lower temperature (which isn't exactly what you paid for lol).
    But yes, the CPU working harder on AC power is perfectly normal.
    Try that Throttlestop configuration, it should help manage temps and energy governance nicely.

    *My laptop is an i5-8300h+GTX 1050 Ti model. A laptop cooler was plugged in during this time.

    Hi,Good Morning! Kindly check the temperature information below.
                        Predator products are engineered to withstand higher operating temperatures than traditional notebooks. These systems include features that help with cooling and heat dispersion. The CPU and GPU are designed to handle temperature spikes in excess of 98 degrees Celsius without causing damage to the components. It is common for PC temperatures to spike temporarily during heavy gaming or graphic usage. If the system encounters excessive temperatures that could damage the hardware, it will automatically shut down to protect the components from becoming damaged.
                  If in case, the temperature is more than 98 degrees, and if you feel that the unit is hot, kindly click the link below, choose your location and contact the Acer Support in your location. I hope it is helpful! :)

    Kindly click "YES" to "Did this answer the question" if my answer helped you!      
    Thank you and have a Blessed Day  :3
  • It's normal bro.

    With the release of Speed Shift technology in Intel CPUs, the CPU is partially governed by Windows Power Profiles. Therefore Windows can designate max clocks, ready clocks (FID), Energy governance (EPP), C0%, idle states and many other aspects.

    The profiles are split between these governances based on AC or battery connections and auto switch between the two as you plug and unplug.

    In fact, I would only be concerned if there was no difference between being plugged and unplugged lol.

    I understand but is the difference between charging and on battery supposed to be this way?

    Thanks for clarifying. I guess what I'm trying to figure out is why on battery temps are lower but have high usage compared to a charging's higher temps and low usage. Max temps never go beyond 95 as far as I can remember. I use XTU to undervolt currently but will check out the link.
