I wanted to know if someone can tell me where can I find a replacement fan for my ASUS ROG Strix Core GL503GE. I came to know that one fan of my laptop is not rotating properly and because of this I can't even set the Overboost option from the ASUS ROG Gaming Centre. This problem started to occur 5-6 months back. The 1- year warrantly of my laptop has also expired in May.
