Is this way too high? Room temp is about 78F. Its running on automatic voltage and stock turbo. At 3.9 its at 1.22v ish.
Also the temperature between the cores varies greatly. With the highest(second core) at 77 and lowest(fourth core) at 70. At idle, highest is at 43, and lowest is at 29C.

Is this just how the ivy processors are designed? Or did I not apply the thermo compounds correctly? I used the dot in the middle method as I always did. Using AS5. I know AS5 is not the best out there anymore, but it should still cut it just fine. In fact, this temperature is even higher than my old phenom IIx4 965. That idles at 34ish, and peak at 58C.

Advise please?

main reason i'm concerned is because the temperatures are very uneven. In my previous experience, the cure period only helps dropping it by 1 or 2 C.
Should I consider remounting?

Can't speak for 3770 (maybe HT makes it hotter?), but in a 21C room I idle at ~29-32C. Not sure how idling scales with increased ambient (yours is 5C hotter than mine). I'm also at 4.1GHz maxing out at 1.17V so maybe you are running a little hot from that.

My lowest temperature core shows 29C idle, which is only 4C above ambient(a bit unbelievable considering I have one fan on that 212 evo). And my hottest is showing 42C idle. My core 1 and 2 are significantly hotter than 3 and 4. Core 2 is 3-4C hotter than 1, and core 3 is 1-2C hotter than 4. With over 10 C difference between 1,2 and 3,4. Not sure if this is just a sensor thing, or i somehow messed up the thermal paste application. It feels like my CPU split itself into two...Normally I heard the temp between the cores should only be about 5-7C difference max? And that by design 2 and 3 should be hottest.

Also when I'm running prime95, the temperature would instantly jump to 75C ish and max out at 79C, then as the fan adjust itself, it will come down slowly and stabilize around 76-77. And by instant I mean under 2 seconds. Then as soon as I shut it off, temperatures drops to 51C within a second. In my previous setups, temperature always increased and decreased relatively gradually. But then again, my last CPU was a Phenom IIx4 965, maybe Ivy is just designed differently?
