I posted a similar thread a few weeks back but I didn't put a lot of information that I feel was important. So when rendering animations in Blender, my CPU is pretty much at 100% load 95% of the time, and only drops to around 80% when switching to the next frame render. I have had this render running for around 15 minutes. Right now my temps are as follows (this is with the NH-D14 cooler running at 4.4GHz turbo boost):

Core 0: 75C
Core 1: 76C
Core 2: 74C
Core 3: 68C
Package: 76C

These are the MAXIMUM temps. They usually seem to sit around the 71C range and occasionally jump up or down.

I am using the thermal paste that came with the Noctua cooler. I heard it is very good.
My case is a Corsair Carbide 200R. I reused it because it is a pretty decent case.
Cable management is OK, I could probably get it a bit better.
Ambient temperature in my room is usually around 24C (76F).
My GPU is a Sapphire Radeon R9 390 which usually idles around 45C; AMD is always obviously hot.
I have 3 fans. Two outtakes, one in top and one at back. One intake in the front.
Running on 2 monitors (although I guess that's mainly GPU dependent).

As I said, turbo is enabled so any load on the CPU runs it at 4.4GHz. I haven't yet attempted any overclocking beyond 4.4GHz due to the turbo. Good enough for me.

Here's my full PC specs:
Mobo: gigabyte z97x-ud3h
GPU: Sapphire R9 390
CPU: i7 4790k
500GB SSD
1TB HDD
XFX Pro 750W PSU (not modular, part of the reason for messy cables).
Noctua NH-D14 cooler.
16gb ram

That's a little toasty for a NH d14. However even with these coolers CPU's have been noted to hit just over 70 degrees under high load tasks.
Is this the maximum you see your CPU reaching?
Some people have reached up to 80 degrees running programs, such as prime95.

What happens when you increase fan speeds? (do this first)
What you can try is taking off the cooler, cleaning thermal paste with 90% alcohol, And try reseating again trying to get even pressure on the thermal paste spread.

The i7 4790k's still get quite hot. Usually with these coolers under high load above 70. Here is another with a max temp of 72 C under prime95.

Try fan speeds settings...

Try fan speeds settings and reseating to see if that makes a difference, ~70 degrees under a very high load such as blender is acceptable.
Under a constant (gaming) load, usually people hit around 65-70 degrees.

-good luck
