Best way to clean the Fan's on a Predator Helios 300?

Hiya, sorry to be a bother, but just wasn't able to find a definitive answer to this question. My Laptop (Predator Helios 300) is sorely overdue for a Fan cleaning, but I don't know the best way to go about it. I have my canned air, straws, and have cleaned fans before, but with this particular laptop I want to take extra care to not damage anything. I can unscrew the back, but peeling it off seems particularly dicey. I just want to know if there is anything I can do to effectively clean the fan without separating the two, and if I do, the best way to go about it so that it doesn't leave any lasting damage. Thanks, and hope to hear back soon

The fan has been reaching upper 4k, 5k RPM while hovering round 80 Degrees. Its also summer over here, so it could just be the terrible heat in the usual room I use being problematic.  Still, its been awhile and I want to treat the laptop with as much care as possible, its served me a good year and I wish to return the favor as best as possible

Just any advice will work, tbh. The user manual didn't mention much about the fan and I may just be paranoid. The strength of the air flow is certainly less powerful compared to out of the box.
