VIII Hero defective?

[Mysterie]

Hey everyone! 🙂

So, I got my new mainboard, installed everything and bootet up my pc, like everyone else.
Played some games with it too, without problems.

A day later I booted it up again, without an error. But every program I looked at was showing me weird cpu temperatures.
Core 1,2 and 4 had temperatures arround 42°c under load. Only Core 3 was hotter with nearly 60°c, even after letting it cool down it was the same, while every other core only had 25°c.

So I thought maybe my thermal paste was bad or something like that, but before I wanted to change it, I restartet my pc.
Well, at least I wanted to. That's where my real problem kicked in.
It didn't boot. No lights, no sound and no qr-code anymore. Like dead.

Plugged my psu off and on again, and by every second try my mainboard shows these red led background light on the left side, but won't start.

Tried to clear cmos, pulled out the battery, tried to recovery the bios, but without any success.

I remembered back, this problem with my hot cores on the cpu. Contacted amazon and they sent me a new cpu. Guess I have to change the mainboard too.
I also noticed, that the capacitor on the left bottom (arround the last pci slot and the sound-chip) is getting really hot.
Means - I plugged in my psu, pressed the start button (which doesn't work anymore, as I descriped above), and noticed temperatures by nearly 60°c there. (shortly after "starting" - 20 seconds or so)

I curios now... what do you think is/was the problem? I'm afraid of starting my pc again with the new components.

Would like to get some thoughts/ideas about that 😮

Edit: Spec

CPU i5 6600k
RAM Trident Z 16 GB (3600mhz)
GPU Asus Strix R9 390
Storage 2x SSD 500GB Vertex 4 (ocz)
PSU RM750x (Corsair - Gold)

Seasonic licenses their PSU designs to several companies like Corsair and many others. I've used Seasonic PSU's in the last 3 builds and have had zero issues with them, I believe the have a 7 year warranty. I recommend the x-series if you're on a budget, should not need more than 750w if you're not running SLI.

I am using this psu. 🙂

I don't think it's available anymore except maybe ebay it's a bit outdated but this is the third pc it's been in. While it's a good psu there are two draw backs with it, one it is LOUD, two it is not modular.

And I fried one of these. 😄

Okay, nearly a week now.

It works! Well, had some problems at the beginning, but who cares.

I tested it with a new psu, all good. Now working with my "old" psu, which I was using at the moment the mainboard died. So far so good, I hope it keeps working in future.
I'm going to change it anyway.

Just have one question -> Why is it so damn hard to get a stable bclk-frequenz (beyond the standard 100mhz)? I only saw people arround 120-140mhz.
Are there any explanation? (in short)
Yes, I used google, but didn't find the informations I want ...
