High temps possibly due to Fans and vents being clogged up.

My unit : PH315-52-5520 is still under warranty.
I'm haven't really done this on a laptop before and am scared of damaging it and don't have all the resources to do the same.
I want my laptops whole cooling unit to be cleaned and maybe even re-paste the thermal compound at the same time.
It's quite clear that it's clogged up as i cant see through the grills, I've tried undervolting (stable at - 0.135V) and all other solutions but the temperatures are still high, peaking at 95 C on CPU, averaging around 91 C. GPU settles at 87 C as that is its thermal limit while gaming/any heavy workload.
So will Acer do this for me?
Will they charge anything extra? 
If yes, how much? (rough estimate)

I know it looks disgusting, it's been 11 months and i move around alot. I live in a very dusty and humid conditions.

    U can give it to acer for cleaning the fans. But from my experience of them repasting it, they did a really really bad job. So repasting u might wanna do it yourself.

    Well.. it's just that i got a month of warranty left probably, if i do the re-pasting myself, i could clean the fans as well right... 
    It's just that i cant get hold of all the resources in this pandemic struck world but acer wouldn't be functioning properly due to the same i guess.

    So i guess it's better i do everything myself then? 
    It's just that its my first time on a laptop and I'm kinda worried about breaking the small ribbon connectors/wires.
    Btw, if i do choose to do it all by myself, which paste would you recommend? MX4 or Kryonaut? 
    I see conflicting results from many people, huge difference only from desktop CPUs where overclocking is being done.
    Will the i5 9300H that i have generate as much heat that i could differentiate the few degrees in performance which most people seem to claim anyways?

    I would suggest u dont open it by yourself if u dont have a pry tool. I ended up doing this and scratches my body in many places(i used a small flat screwdriver). Also there is a high chance u may break those latches if u dont have something thin and strong enough to pry the back case. If u have a pry tool u can easily do the repaste by yourself. Just disconnect the battery and remove the fan plugs. Dont pull the small connectors by the wires and there is no reason to touch the ribbon connectors. Kryonaut is the best thermal paste so if u want best performance go with kryonaut. I have an i5 8300h and even with a bad repaste job, kryonaut gave me about 15'C better temps(once I do it properly ill let u know).

    I've already ordered some driver bits and some Ram for upgrades.

    Thank you for the advice, I'll have to clean this thing though, if i just take it to acer, like you said earlier, they might do a bad job at re-pasting and maybe even cleaning, so i kinda wanna give it a shot myself. I'll make sure to use something plastic/wooden tool for prying. Kinda excited/worried.
    It's just that Kryonaut is really expensive when compared to MX4 and i probably won't have much of the paste left if i mess it up and have to redo or open it up later once again to clean the fans, which i think I'll have to do regularly keeping my environmental conditions in mind.

    Also, what about the pink thermal goop on the vrams? Did you replace them with a pad/paste? Or did you just the panel back on?

    I haven't changed the pads yet. I will be changing them soon. It is better to change them too since u r going remove the heatsink.

    I see, it just seems a little too pricey to get all this stuff for possibly one use
