so after the release of Horizon zero dawn I realized how pathetic my GPU is (Gigabyte 970 G1) and decided to give overclocking a try. I found out that my GPU runs so hot under the stress test (Valley) up to the maximum temreture, I even unlocked the Power/Temp link and gave it headroom up to 90C and it went all the way up. keep in mind this is without changing anything else.

I noticed also an increase of core clock (35-40 MHz) when I increased the Temp threshold.

is this normal? I'm sorry if this has been answered before over and over again but I cant find any info of a GPU running so hot without overclocking it.
 
Solution
Being an older 970 it may need a good cleaning of the fans and cooler, it may also benefit from replacing the thermal paste.

Good case airflow and ambient temperature also are key factors.
