Recently while gaming my gpu has been getting to temps of 90C max.
Where it used to get to 70C max.
I have had the card for about a year, drivers are up to date and I have cleared out the dust.
My cpu maxes at 40-50 and my case is not getting very hot.
I have had the card for about a year...
drivers are up to date...
I see two possibilities just from that, the fans are wearing out (Do they sound any different?), or when you updated drivers, the fan speed behavior changed (Have you checked to make sure they're still set to a "cooling" profile, rather than a "quiet" one?)
