my temps shoot up to ~100c and Core Temp starts warning me...
I am guessing this is a problem...
At idle the temps sit around ~33c

adding a 2nd fan to the cooler so one blows and the other pulls air through it might help but such a huge spike in temps is concerning.
Civilradiant when you do the load test does the temperature spike or does it just gradually keep slowly rising until it hits 100.
if it's gradual and unmanageable then the cooler is most likely mounted properly.

I did that with my new 4790k when installing my aftermarket tower cooler (Phanteks PH-TC14PE), but I realized as soon as I had finished installing it and hadn't connected the power supply yet, so I just had to take it back off and remove the film, then reapply a dab of thermal compound and put the cooler back on.
For comparison, I ran the same test with the same programs you indicated. My idle temps are ~36 C (room temperature is ~25 C), and for most of the burn test the cores are all ~60-65 C. Midway through each run on the burn test, there is a very brief temperature spike up to 78-80 C for cores 0 and 3, and 81-85 for cores 1 and 2. That immediately drops back down to the low 60's for all 4 cores, while still showing 100% load. The full 10 runs complete successfully.
This is also while running a very minor overclock, set automatically by the BIOS to 102.0 x 44 = 4488 MHz.
Our i7-4790K is actually one of the lower performing CPUs from what I have heard from other reviewers. Using a Corsair H80i (the 120mm double thickness CLC), our CPU hit 4.6 GHz at 1.300 volts, with 86ºC peak temperature under OCCT load, and 4.7 GHz at 1.450 volts with 98ºC peak temperature under OCCT load.
@ Idle my temps are hovering around 40c but when I initiate the stress test my temps shoot right back up to 100c
Notice that in the second pic above, the VID ( cpu voltage ) shoots up from 0.95 volts in idle mode all the way to 1.27 volts under full load!! That is way too high for this cpu imho!! Never go above 1.20 volts, and preferably 1.1 volts or less... check your cpu voltage setting in your mobo BIOS.
that fact that your cpu is spiking to 100 so quickly is very concerning.
