Laptop overheating, but the fan won't spin at max rpm

I have had an Acer v3-571G for about a year now. I play a fair bit of games on this thing and it was pretty decent regarding the temps. Right when I got it I tested it by playing nonstop for 2-3 hours and the cpu temps were at 80-85C which seems like alot but from what I've gathered It's pretty standard for a 15.6 media laptop. Recently however I noticed alot of performance drops due to throttling even after 20-30 mins of gaming so I decided to check the temps using core temp and I was pretty shocked to see that it was sitting at 90+ and got to 99C... at one point. The fan however is not even close to spinning at max speed. I can't actually monitor the fan profile or rpm because no software can detect it and it's not in the BIOS either. Just from hearing though I can tell that it's spinning at about it's 3rd fastest setting because earlier I remember this thing sounding like a vacuum cleaner at times, when the temps got really hot. I don't mind the noise, I just want to game at ''safe'' temps. There is no dust on the outside, the laptop sits on a nice flat table and I know that there could be some dust inside after a year but even so, the fan should just be spinning faster more often trying to cool things down. The GPU also seems to have taken a hit in the temperature department as it used to be at about 70C under load and now it's over 80C. Hardly surprising since there's only one fan.

The CPU in question is a i5 3230m on win7 Ultimate x64 with all drivers. Paired with a 730m.

So any ideas on what's wrong and what could be done here ?

Did you try to see if FanSpeed detects your fan? I still use it from time to time.

Regarding the dust, you should open it up and clean it. There might be a layer of gunk under the fan, making it kinda useless.

If you meant SpeedFan then yes I tried, but it doesn't detect. I guess it could make sense that there's so much dust that the fan is physically unable to spin any faster. I don't have much knowledge about laptops so I'll take it to the repair shop probably. If that's the only thing left that could help.
