I7 6800k Running hot?

[admrl]

Mobo: Asus Deluxe ii CPU: I7 6800k Ram: g.skill tridentz 32gb 3200 MHz PSU: 750w evga g2
So I have a stable setup at 1.28V for Vcore, overclocked to 4.4 GHz. The only issue is that my temps under full load are pretty wild. I reach about 90C on prime 95 with the blend test on my worst core. My worst core is about 15C hotter than the best. To me that seems a bit high considering I am using a liquid cooled system. Idle temps are good at fans at full blast I get min temps of 19-20C. I have the EK supremacy evo, ek d5 xres pump/resovoir, and ek coolstream xe.
I have also re-seated the block and reapplied thermal paste.
What do you guys think? Did i get a dud? Should I exchange it? any advice is welcome thank you.

Which version of Prime95 are you using? For Haswell-E and Broadwell-E(others as well), 26.6 is the newest version to use, as the newer versions use AVX instructions and can really heat up the CPU and VRM powerdraw goes through the roof.

Wow 4.4ghz at 1.28v that is insane. Mine was crashing at 4.4ghz and 1.35v. Please let me know how your setup is doing now.

Thought I was good at 4.3ghz at 1.28v until I ran OCCT and it decided I wasn't.
My most stable now is 4.2ghz at 1.28v.
