Kryosheet on AMD 7900xt disappointing results.

Just installed a thermal grizzly Kryosheet thermal pad on my AMD 7900xt GPU and the result have been disappointing to say the least. Where my expectations to high or am i missing something?

my goal was to lower the fan speed but the junction temperature shows almost no improvement so the fans keep running at around 2000rpm

I used Furmark as a stress test both configurations ran for 20 minutes.
