Question 5950x running really hot under idle

[rocktrout]

Hey,

I’ve been running a 5950x cooled by an Arctic Liquid Freezer ii 280mm but both my idle and under-load temps have been a lot higher than I expected. Idling in the mid to high 70s in BIOS and under the smallest and largest loads at 90-92. I’ve tried reseating and reapplying thermal paste but it doesn’t change anything. I’ve also tried turning off PBO and it basically looks identical to having it off. Not sure where to go from here.

Thanks
