This is with PBO enabled during an MT Cinebench run, I don't want them to downclock.
I think these clockspeeds are low for PBO enabled.
Seems to be related to my temperatures, who knows even my bad results without PBO are.
I will take pictures when I remove my Arctic Freezer 360 so you can determine if it was correctly mounted perhaps.
The PBO temps are a bit high if you have a 360mm AIO. I also have a 360mm AIO and my PBO is more aggressive so it draws an extra 40w over yours and my max temp is 10c lower than yours
