Sudden and rapid FPS drop in games?

Hey guys, I've recently started noticing huge and rapid FPS drops after a minute or two of gameplay on a laptop that I've had for about a year. Once the FPS starts dropping, if I quit the game and immediately start it back up again, it again has good FPS for a little while only to drop back down again. Also worth mentioning that I haven't noticed this in less demanding games like CSGO (although I get about 200 fps in this game so maybe that's why?)

Here's some screenshots I took for monitoring data-

Before FPS drop:

(in case you can't see the images)
GPU: 78 celsius, 98%, 1038 mhz
MEM: 2506 mhz, 1463 MB
D3D11: 60 fps
CPU1: 53 celsius, 62%
CPU2: 53 celsius, 57%
CPU3: 54 celsius, 65%
CPU4: 53 celsius, 69%
CPU5: 51 celsius, 56%
CPU6: 51 celsius, 57%
CPU7: 52 celsius, 54%
CPU8: 52 celsius, 60%
CPU: 54 celsius, 60%
RAM: 6271 MB

After FPS drop:

GPU: 76 celsius, 99%, 532 mhz
MEM: 810 mhz, 1482 MB
LIM: Temperature
D3D11: 26 fps
CPU1: 50 celsius, 37%
CPU2: 50 celsius, 32%
CPU3: 50 celsius, 32%
CPU4: 50 celsius, 22%
CPU5: 49 celsius, 40%
CPU6: 49 celsius, 17%
CPU7: 48 celsius, 36%
CPU8: 48 celsius, 19%
CPU: 51 celsius, 29%
RAM: 6312 MB

What I've tried so far:

1. Running Malwarebytes in Safe Mode and cleaning viruses.
2. Registry clean up
3. Disk check (says no problems)
4. Updating all drivers
5. Uninstalling GPU driver and reinstalling again
6. Tampering with power settings
7. Use cooling pad
8. Defragmenting HDD
9. Restarting laptop to factory settings

Specs:

GPU: 970m 6gb
CPU: i7-6700 HQ @2.60 HZ
8gb of RAM
Windows 10 home

I still have warranty on it for a few more months but I'm not sure if I should send it in or not. Anyone have similar experience or know anything else I can try? Could opening the laptop and doing a thorough cleaning of its fans and vents help? Any help would be greatly appreciated.

Don't know if I'd call it a GPU problem per se. It could just be an airflow problem keeping the gpu from being able to remain cool. Some report that their 970m's get up to mid 80's (adjustable in card settings). In most cases with laptops, there are vents on the bottom that become restricted and simply raising the back of the laptop a little is enough to resolve some heating issues. I'd recommend finding where the vents are, blasting some compressed air to clear out any dust and elevating it a little, making sure no vents are blocked. If you're still seeing an increased amount of heat, you could contact the manufacturer about it, but in most cases, they won't do anything (doesn't hurt to try though as it is still under warranty)...

*EDIT*

As SoggyTissue pointed out, it does appear to be a temp issue and my original assessment below would be incorrect. Follow their advise on the temperature matter and if you still have an issue after that, then you can check the RAM.

*END EDIT*

Most likely, the problem is that you're running out of RAM and that's causing the problem (in my opinion). Looking at the screenshots and details, the temperature isn't an issue, CPU Utilization isn't an issue, and the Graphics Card isn't an issue. Check what your memory usage is at while playing CS:GO and a few other games and see if you notice a pattern.

IMO
the low fps is because your gpu has halved its clock speed and mem speed.
the temp is less because it is thermal throttling. see that 3rd point? LIM = limiter = TEMP
laptops tend to have a tighter limit on the heat because of how hazardous to your 'lap' it might be. pcs dont sit on your lap, no chance to cook your leg.
have you attempted to clean the gpu pipe-fan? could just be the summer weather means its harder to cool than in winter.

less demanding games require less gpu time = less heat generated.

also: check to see if there is any heat pipe / fan damage as its within warranty too.

If they refuse to do anything, you could try a more "hands on" approach by opening the system, cleaning off old thermal paste, and applying some new thermal paste (and while it's open, a thorough dust removal).
