Noctua D14 Temperatures for i7 normal?

The airflow is plenty no doubt. Well, the temps are hot considering you have a top notch cooler and GREAT airflow. But the fact that thermal compound takes some time to settle down for effective performance should not be neglected, wait for a couple of days, maybe 4-5, and you'd notice improvement. 80C on prime95 with that cooler on 4.4GHz is hot no doubt, it should be under 72C.
I'd wait for a couple of days until the compound sets in, you should notice difference.

Yes you should expect temps comparable to H100i, D14 is a beastly cooler indeed. Well it should not surpass 70C on Prime95 and 60-65C on intensive BF4 multiplayer would be fine, it depends on the room temps too, if it's >30C, then you'll expect something like 62-68C on BF4 and <75C full load temps. 4.4Ghz is a slight OC, so you should be good in a couple of days if everything's fine

It indeed is, even after better integreted heatsinks it runs a bit hot, that's well known. But the Prime95 temps are not so good, as you mentioned, 80C is too high.

Try using a different version of prime95, you may have got a bad one.

Those are surprising results, My 4790k with a D15 is at 4.7ghz 1.25v, 27C idle, 64C load, though there is more airflow space in an enthoo pro compared to yours pictured.
Even though case fans make just a few degrees difference (in good setups (adding 3x140mm top exhausts made no difference to my temps so i left them out to aid silence)) compared to the cooler itself, hopefully the 3 front intake fans are static pressure instead of airflow

That kind of explains that your temperature is a bit higher. Your case shouldn't feel hot, though. Try leaving it open (one or both sides) and test temperatures then again.

Maybe i can move heat out better because my case is alot larger, phanteks enthoo pro.
The PSU also has airflow separate from the rest of the case, intakes from grill at base of case and exhausts out back, separated from rest of case airflow by a shroud which encases it. If your case has grills at the bottom of the PSU, try flipping it over so it intakes air from bottom and outside of the case.
Do you have dust issues? I use an airduster weekly, just because dust is visible with the lighting through the window.

You are using a D14, i use D15, shouldn't make much difference in temps but it does use 2x 140mm fans rather than 140+120mm. The core cooling components are what impact temps the most, but ofcourse you need the good case airflow to keep the hot air exhausting and cool air coming in.

Surprised with all those fans you cannot get the air to move out, if the case really is getting hot, (air exhausting from mine feels like a cool breeze you need a jacket for) try switching the front intake fans into SP140's (static pressure) to help move air through those drive cages better, that will get the air flowing to the real components better. Maybe you want to try changing all fans out for quality fans altogether, Mine are intake Corsair SP140 LED and exhaust corsair AF140 Quiet Edition. For LED lighting the windowed case, i use the NZXT HUE.
I did add top 200mm+140mm exhausts (case stock fans) but made no difference to current temps and don't really want to OC passed what i have for now, will full water kit when i want to mess around more

Here is my build, built few weeks ago, will add pics when i finish messing round with case fans and extra internal drives. All fans are controlled through my motherboard UEFI, the 3pin fans too, thanks to a PWM hub included with the case with 3pin headers.

My SSD is fixed to a bracket behind the motherboard, so a drive cage at bottom front of case was not required, then i needed the cage for a SATA drive so used static pressure (Corsair SP140 LED) intake fans there instead of airflow.
Perhaps you can remove the cage and fix the ssd elsewhere? may improve the intake airflow to rest of components
Also seems like the drive cage at bottom is position wrongly, sideways? allowing for least airflow through to the gpu/mobo

Try resetting to stock clocks, see if the case can remain running cool. If it does stay cool, do the OC again or restore it from a saved profile. If not running cool at stock clock, switch out those case fans for quality ones. Which fans exactly are they by the way?
