Acer Nitro 7 CPU Throttling Issue when loading CPU

chinnu_1645

I own a Acer Nitro 7 AN715-51 model gaming laptop (Intel i5-9300H). Recently I noticed that while running games or any other benchmarks my cpu clock speed drops from the usual 3.9 Ghz to 2.0 GHz or even lower and stays there. As soon as the application or game is closed or minimized the clock speed comes back to almost 4.0 GHz. I do not understand why this issue occurs. The BIOS is at latest version for this model.

• Temperatures ranges around 75C - 95C which is normal from the time I got my laptop
• And no, my laptop used to run at these temperatures AND AT MAXIMUM FREQUENCY without any throttling although it would show Thermal Throttling in ThrottleStop.
• Clock speed is normal while Idle
• I have not undervolted or underclocked my CPU/GPU
• I reset/re installed windows already and issue still persists
• I have also updated my BIOS to the latest version available
• Related Screenshots
• I tried to disable BD-Prochot, Intel Speed Step and every other major possibility that I found on the internet.
• Maximum & Minimum Processor State is set to 100% (Power Plan: High Performance w/ maximum performance settings AND Fan speed at Maximum)

At this point I'm clueless as to what is causing this issue.

I booked an on-site service and the technician did a thermal repast before 1 week and partially cleaned the exhaust fans. So I don't think that this is related to temperature.

The main problem here is:
The laptop stays IDLE with 92° C temperature and RUNS AT 4.07GHZ (AT MAX) and never throttles down to less than 3.5GHz WHEN IDLE.

The laptop remains at 92°C temperature and as soon as I launch a game (say CS:GO, for example), the clock speed throttles back to less than 2.4GHz and never goes up.
As soon as I minimize the game, the clock speed hits to the maximum possible value i.e. 3.9-4.0GHz. Once I return to the game window, it throttles again.

This is not just for any game but also during stress test. With these temperatures I ran stress test on my CPU before like 2 months, and it hit a maximum of 4.1GHz speed. But now, it doesn't even cross 3. The temperatures are same now and before, but there's this issue.

I've had these throttle notifications when I stressed my CPU when I bought this laptop and still hit the maximum frequency.

I updated my BIOS earlier when I bought this laptop itself, and never touched it till now.

I even tried to disable BD Prochot using Throttlestop, and I still had the issue occuring.

Finally, yes, I tried undervolting before to reduce the temperatures but that didn't help at all. So I reverted them back to default values.

One thing I would like to add here that is very interesting is:
I use ThrottleStop to undervolt my laptop CPU, and the strange thing that I noticed during stress testing today was;
As soon as I start stressing the CPU, the Core Voltage (1.2V) reduces to approximately 0.9xyz and varies upto 0.97x (x = 0..9). When the stress test ends or if I stop it, the voltage goes back again to 1.2xy VOLT.
Another vision is, the clock speed multiplier (41x, 41x, 40x, 40x) comes down to around 32.1 when stressing. If you don't understand what I exactly mean, I could try to send a video demonstration of the issue.
