Fans are running on full blast and laptop is overheating.

Hey guys, so here's my issue:

Randomly yesterday, while browsing the internet, my laptop's fan started getting pretty loud for some weird reason, like there's something stuck in it. This happened on my Windows partition.

So, next thing I do is just clean the internals of all dust.

After that, I tried resetting the SMC, but either it's not working or it has no effect. My Magsafe charger doesn't change light colours like other people's do.

I'd really love if anyone knows if this issue can be solved, since it's causing a lot of overheating and my fan is running ridiculously slow after this.
