Are you using prime95 to test? If so and you're sustaining 74-76C then yes your temps are fine considering you're using a Noctua air cooler with 1.33v on it. I for some odd reason don't believe your idle temps though.....I smell a miscalculation on your part or a lie. I could possibly see 25-27C idle temps but not in the teens.
I was using real temp and ran prime 95 with it. Idle temps on real temp were bouncing between 15-17, with no load... And then the max temps were
Around 75. I thought idle was low but I wasn't about to complain... I'll have to try again and get a picture of it if it repeats. I did run prime twice though with similar results for both idle & load.
