Recently i was gaming as usual on my F516PR and started to notice a loud/quiet/loud/quiet stutter of my GPU fan. Opened it up as usual for a clean, checked if all is good, and seemed okey. Later the same noise started, with a louder noise following - and then dead, not spinning at all. I thought its the fan itself, so I ordered a fresh pair of both fans. Replaced them today, CPU fan all good as previous, GPU fan dead. Is it a circuit issue ? Most likely. I am keen on fixing this myself, but if it needs problem identifying with infrared tools and such, then no can do sadly. Maybe someone had this issue ?
