[SOLVED] Laptop GPU behaving weird

Hello. I'm having issues with my laptop, unfortunately it fell off my lap when I dosed off recently and landed on its back. Initially after turning it back on, the display seemed off, so after disassembling it I found out that it was just the display connector that went loose, and after plugging it back it was fine. I can enter Windows and roam around just fine. However, I've also noticed that one of the fans got damaged, several of those "fan wings" or whatever they're called are broken, so there's quite a gap in the fan now. (I suppose it's a GPU fan.) Also it's a bit louder than usual. But the main issue is that the GPU doesn't seem to behave properly anymore.

Specs:
Asus ROG Strix GL703 GS
i7 8750HQ 2.20GHz, 6c/12t
16GB RAM DDR4 2666MHz
GTX1070 8GB GDDR5
Samsung NVMe 256GB + Transcend SSD 512GB
17.3" Full HD, 144Hz, Anti Glare IPS, G-Sync
Win Home 64bit

So, the first thing that I've noticed is that the Asus Gaming Center tells me that the GPU Perf Limiter is now always set on Power (used to be on Utilization), and the clock core is variable, but mostly way lower than usual. With Apex Legends being my so-called main game, I've done some tests with it and got several different results. I have also installed MSI Afterburner simply to get the GPU performance stats via its OSD.

1- First test seemed fine initially. I have been able to play the game just fine for about 10 minutes. The initial FPS was 144, but something did seem wrong. The FPS started descending slowly, and had regular hard drops (from max to about 60-70 for 2 seconds, then gets back). However after those 10 minutes the frame rate sudddenly drops and stays below 10. This is where I quit the game and wait some time before new test.
2- The next test ended in the main menu of the game, where I had 10-15 FPS. I checked the Gaming Center which told me that the clock core was 139MHz and the Perf Limiter set to Power.
3- After re-booting, I have instantly opened Gaming Center which told me that it was now on 1300+ MHz (the usual) and Utilization. I started the game, and got the same thing as in case 2; suddenly it was back on 139MHz/Power.
4- After another re-booting, and running the GC instantly, it was 1300/Utilization for a whole second, then reverted back to 139/Power.
5- This is where it stayed at 139 for several tests. The game runs around 10 FPS.
6- However, during my last testing, and at the time of writing this text, the clock core somehow stays at 645MHz, still on Power. This is enough to have 25-30 FPS in-game.

During all these tests I have to note that the GPU usage was ~99%, but the temperature was ~50-55 Celsius. CPU usage varied from 10-25%, temperature was 60-70 Celsius. Under normal circumstances CPU is cca 80, GPU cca 90 Celsius. I didn't mess around with the settings in MSI Afterburner. What I did mess around with are the "usual suspects"; the performance plan (which is high performance), Ge-Force Experience and Control panel settings, etc. Also I've tried disabling/enabling the NVIDIA adapter via Device manager, when I re-enabled it, the screen just went black, and I had to re-boot it. I haven't tried re-installing the GPU drivers and software. I can't really tell whether it's a software or hardware problem. Any advice?
 
Solution
You have a broken GPU fan. That fan will have reduced life span until the bearing wear out.

Also, the GPU/CPU would not be able to get rid of heat as before, and therefore the drivers (or other software) will try to compensate for that. This is what you see the results of now.

It may be more that is broken, if not everything you listed up make sense as being a direct cause of a bad fan.
