Fried my CPU. Cooling Recommendations?

Hello. I built my own system, details below, for photo editing - primarily Photoshop and DXO Optics. During conversions from RAW to JPG in DXO Optics, the CPU runs at 100%. Last evening, I was doing conversations, and the CPU was at 100% for maybe 20 mins straight. The programs were starting to act a bit strange, so I shut the system down. Now, no POST, and the CPU is fried. I'm embarrassed to say, but this is the 2nd time I've fried the CPU. The first time, I thought it was a bad MB or CPU, so ended up replacing both. That time was after a stint at 100%, too. So, I'm fairly certain it's a cooling issue (but I'm open to other suggestions). The build was considerably cheaper than off-the-shelf, now not so much.

My first question, assuming it's a cooling issue, is shouldn't the CPU or MB shut down in an overheat situation?

Next question is, assuming it's a cooling issue, what more is needed?

The cooling is CRYORIG H5 Ultimate Mid Tower Cooler, and the stock case fan.

Should I upgrade the CPU fan/heatsink? Should I add additional case fans? Could the MB (ASUS Z170-A) be an issue? Should I change the fan profile to higher RPMs?

Any/all input will be appreciated.

System:
- Intel Core i7-6700K 8M Skylake Quad-Core 4.0 GHz
- CRYORIG H5 Ultimate Mid Tower Cooler
- ASUS Z170-A MB
- Ballistix Sport LT 16GB memory
- SAMSUNG 950 PRO M.2 512GB PCI-Express 3.0 x4 Internal Solid State Drive (SSD) system drive
- Fractal Design Define R5 Blackout Silent ATX Mid Tower Computer Case

I run a i7 2630 for 5 years a few times a week at around 90C 100% load for several hours (VFX frames) and still not fried. Truth is, the only way to fry a CPU would be to increase the voltage to the point the PC wouldnt even boot.

Look into your cooler installation. Plastic leftover, thermalpaste air pocket, lose screws, etc.


All the best!
the Cryorig H5 Ultimate is actually a pretty good cooler
could be it's bad placed on the CPU or thermal paste was poorly applied
could be that the overall airflow isn't good inside your case, although if you assembled it properly the R5 is pretty good
normally there are safeguards in your BIOS that warn you if the CPU gets too hot and should cut the power at a certain point, unless you disable it
it's a strange issue from what I can tell. I think it might me a board issue but it's just a wild guess.
 
It sounds less like a cooling issue (provided the cooler was installed correctly) and more of a problem elsewhere. Unless you're running some crazy voltages or something there's no reason that should have overheated to the point of destroying the CPU. Are you running it with stock settings?

Amaranth - Yes, stock settings on MB, no over locking. Also, did the Asus fan thingy fan calibration.

[edit - sorry azaran, damn autocorrect.]

I was quite meticulous. However, I suppose it's possible that I very carefully installed it incorrectly.

I should add that the system had been running great for about 3 months prior to failing. But this was, I believe, the longest stretch at 100% CPU - 20 mins or so.
