Right after HS installation:
CPU: Intel Devil's Canyon i7-4790K (no OC other than what the MB does by default, manual RAM settings to match advertised specs)
4.4GHz, 1.312 vCore, CPU power: 116W (max)
MB: Asus Maximums VII Hero
Cooling: Corsair H80i 120mm, Push 25xx RPM max/Pull 22xx RPM max (limited to avoid annoying whine sound), stock fans, adaptive fan speed
Corsair Pump RPM: 2209
Liquid T: 42.6C (max)
Ambient T: 25.7C
Paste: AS 5
----- Update ----
~3 weeks after installation:
CPU: 4.4GHz, 1.312 vCore, CPU power: 118W (max)
Liquid T: 43.7C (max)
Ambient T: 26.4C
Looks stable at 75C (twice went to 76C (red color) briefly) in AI Suite 3 after 24 minutes of stress testing. Fans started spinning at max again when temp hit 75C. Corsair CPU temp: 82.3C (max)
----
I took just under 18 minutes of loading all 8 threads using SP2004 by Johnny Lee to reach temperature of 82.1C (Corsair Link) / 75C (AI Suite 3).
A note about other fans in the system. Once AI Suite 3 went over 74C all my fans (connected to MB via headers) started spinning at max speed. I normally have them at comfortably audible rotation. 75C was also reported in red by AI Suite 3, while <=74C were in white.
I took about 16 minutes for the CPU to cross over 80C (Corsair Link), it was between 76-80C during the first 16 minutes.
Once the temp crossed over 80C it seems like it was going higher and higher slowly, as if the cooling was not keeping up with the CPU anymore. I stopped the stress test.
Did I put too much paste?
Are my temps pretty much what should be expected by using mid-level cooler? I know there is a twice as big radiator that can be top mounted which probably would fair better.

Right after HS installation:
CPU: 79C (Asus), 84.8C (Corsair) after 17 minutes.
CPU: 4.4GHz, 1.312 vCore, CPU power: 117W (max) Once or twice 1.328 vCore.
Liquid T: 41.8C (max)
Ambient T: 26.7C
Stayed in 79C for a while until the end of the test.

Right after HS installation:
Appears to have a little more paste than T1.

Once or twice hit 79C briefly.
After little over 3 weeks:
CPU: 79C (Asus), 85.2C (Corsair) after 22 minutes.
Liquid T: 43.3C (max)

Right after HS installation:

CPU: 4.4GHz, 1.312 vCore, CPU power: 117W (max)
Liquid T: 42.3C (max)
Ambient T: 27C
Peak: 77C (briefly about 6 times)
Based on the above tests my conclusion is that very little paste is needed. In the final, 'X', application I could have probably used less paste. Maybe even 2x as less. No matter how much paste, after HS is applied, the paste must cover the entire CPU.
In all cases where CPU was not covered entirely I had higher temps. I expect the 'X' application to cover the CPU entirely. 'X' is the paste application I'm running right now.
So far it seems like the T0 application had the lowest temps, though I'm expecting the 'X' application to have similarly low temps. That is 75C steady with 3-4 brief crossing to 76C.
