AN515-58-GPU temp-Why did the CPU temperature decrease, but the GPU temperature increase?

Hi, I have an Acer Nitro AN515-58 laptop with an Intel 12th Gen CPU.

I recently replaced both the thermal paste and the thermal pads.

I use arctic mx4 for thermal paste and 1mm for pad

Before the replacement:

Max CPU temperature was around 91°C

Max GPU temperature was around 71°C

After the replacement:

Max CPU temperature dropped to 71°C (which is great)

But now, the GPU temperature reaches 88°C, and sometimes even hits 90°C

I also cleaned both fans during the process.

My question is:

Why did the CPU temperature decrease, but the GPU temperature increase?

Is this behavior normal?

For additional context: these temperatures were recorded while playing Genshin Impact.

    No, You might have done any mistake while applying paste on GPU chip or thermal pads on Vrams. You need to do thermal pasting again but this time do it in my method. Check my comment in below post I shared for best results and application.

    (My comment in post show how to apply paste, clean properly and what not to do)

    You can use Arctic MX-4-it’s very good-but I recommend getting TG Putty for VRAMs, as it eliminates the risk of incorrect measurements and gaps, and is more effective than thermal pads. You can check youtube video for instructions if had difficulty in apply putty on vram chips.

    A decreased CPU temperature with an increased GPU temperature in an Acer Nitro 5 could be due to a few reasons, including:

    1. Shift in workload:
      If the user was previously performing tasks that heavily taxed the CPU (like complex calculations), then switching to tasks that heavily tax the GPU (like gaming) could cause the GPU's temperature to rise while the CPU's temperature decreases because the CPU is less actively working.
    2. Overclocking or thermal paste issues:
      Overclocking can cause the GPU to work harder and generate more heat, especially if the cooling system isn't designed to handle the extra heat. Incorrectly applied or outdated thermal paste can also lead to higher GPU temperatures.
    3. Airflow issues:
      Poor airflow or blocked vents can trap heat within the laptop, especially if the GPU is positioned where airflow is restricted.
    4. Dust and dirt:
      Accumulated dust can block airflow, reducing the efficiency of the cooling system, and leading to higher temperatures.
    5. GPU workload intensity:
      The type of task being performed on the GPU can influence its temperature. Heavy workloads, like gaming or video rendering, can cause the GPU to work harder and generate more heat than lighter tasks.
