That very slight gap I see is easily thinner than a hair between the top of the ihs and the pcb side.
There seems to be a noticeable gap around the IHS when on the die which causes it to ever so slighty sit above the pcb or rather rock on it depending which side gets more pressure applied. I am certain that wasn't there when I installed it originally, at least not to the extent it is now.
It certainly looks like the waterblock bow and mounting pressure from my supreme-hf has caused it to bend the IHS the smallest amount, but enough to kill the CPU after a month or so.
It sure sucks and ill hope that my replacement comes tomorrow so I can see if it was just the cpu that died and hope my board is ok.
That sucks man... I'm definitely thinking the waterblock must have bowed it just enough to crack the die - it wouldn't take much at all. I'm not going to jump the gun on "fixing" mine since you seem to be the only unlucky soul I've seen that has had this happen and my block is perfectly flat. I also used a blade to delid because I was worried about my IHS bowing, perhaps with good reason.
Live and learn, maybe the next chip will be a better clocker
