Help with ASUS DUAL-RX5700-O8G-EVO


I am a beginner to mine eth.
My Asus RX5700

Men temp is always 100C with 128W @58.5Mh/s
And no matter how I adjust, fan speed is only 81%。About 3000rpm.

I modded the BIOS.

And I don’t want to change the thermal pad because my warranty will be voided if I do that.

Please can someone help me with the temp issues? Thanks!
