Broken laptop fan bearing for a really really old gaming laptop

I own this alienware m15 r1 that's been pretty beat up lol. Haven't really taken excellent care of it, the CPU fan broke down like 3 years ago but I've kept using it with no real issues. Until a few months ago the GPU fan also broke, and that wasn't that great of an issue either until now where the bearing is sounding super super loud. I can order new fans for the laptop for like $50 but wondering if it's even worth it for a 6 year old laptop? Could I just take out the fans completely and rely on external cooling..?
