Asus ROG Strix G713QR - Replace fans

Hello,

has anybody replaced the fans on the G713 or some equal model? There are a few around an amazon for example, maybe there are some suggestions for quieter ones. My fans have a really annoying whiny noise, i can get around most times with some tweaks in armoury crate, but under load or when i'm gaming, the noise really stresses me out. I was wondering, if there are some people who tried replacing them. Hope you understand what i mean, english is not my first language.

Have a great day, and thanks in advance for any replies or ideas!
