Whilst I play CS:GO on my laptop the game runs smoothly until 10 minutes later where it hits 91°C and it's on 97-100% load. I tried to tune down the clock speeds on MSI afterburner but that didn't change a thing. The GPU normally runs at 800-1000Mhz but when thermal throttling it can go to 200-400Mhz. I checked the fans and they were quite dusty. I cleaned the heatsink and got all the dust out however this didn't change anything, so I ordered a descent laptop cooler (Havit HV-F2056) to try and fix the temps and the cooler only changed the temps on my laptop -15°C on idle however did nothing under heavy load. The CPU also hits high temps of about 90°C.

Here are some of the laptop specs (ASUS N550LF-CK095H):

- Intel Core i5 4200U @ 1.6Ghz (2.4Ghz boost clock)
- NVIDIA GeForce GT 745M 2GB VRAM
- 6GB RAM @ 1600Mhz
- 500GB Hard Drive
- Windows 8.1 (Windows 10 completely breaks my graphics drivers and causes the card to stop working)

Would appreciate some help, thanks!
 
No but I've ordered some isopropyl alcohol to remove the old paste on the cpu and gpu and I'm replacing it with arctic silver 5 paste. Is that a good idea?
 
Yeah, the temps are the exact same, though when i removed the old thermal paste there was paste overhanging the actual frame of the cpu/gpu and I didn't want to remove them since I might've broke something..
