Quick question regarding my GPU, I play relatively new titles, but right now mainly PUBG and it reaches high temperatures when the fans are working at 25-30%. Is it normal and safe for me to boost the fan speed, I usually do that always, I boost them up to 50-60% so the temperature usually reaches tops 65C. If the fan speed is down to 30% the GPU reaches up to 80C. So, should I keep the fan speed a bit higher every time I play and does it affect my GPU life span. Also, it's been a few months since one of the fans started making weird rattling noise which annoys me, so does anyone know a site to purchase a new one? Thanks.
