So from today morning my fan started making noises and i think one of the fan is spinning too slow so my omen 16 is around 2.5 years old and i got it cleaned 2 weeks back it was working fine but today it started making noise again, so I’m thinking of changing the fans and installing new ones. Is there anyone who would suggest what fans should i buy any links or any other help would be appreciated. Thank you in advance

Also is there a need to back up my data for fan changing and can i use it in the mean time.
