So the standoffs for the bracket from the CoolerMaster 240M have pushed into the back of the Mobo and cut track? Did they not alight to a backplate of some sort? Either way totally gutted for you
Are you testing the components on this board or a completely different PC?
Not the back, at the front, upper right CPU block stand off. The copper tracks on my motherboard are like many, slightly raised. I tightened these by hand, and it looks like the edge of the stand off just cut through the motherboard insulation, creating a short, and destroying the motherboard when I powered it up.
It all looked fine, the CM backplate is great with little plastic clips holding the bolts in place etc, it just wobbles a bit when I tightened the stand off's as there was not much room, and when I screwed the CPU block in place a couple of the stand off's turned a bit.
The cooler itself seems great, very quiet, it's just the stand off insulators and instructions that are in question.
I will try an add a picture of the motherboard damage later, you can see a cresent shaped abrasion line on the tracks I mention.
It was looking rather nice for such an old system, I had added a Samsung 840, but just an old GPU and PSU for the test, with the RGB lighting with a remote, it powered up, nice RGB led showcasing the interior with a white glow, then a pffft noise and smell of burning.
For this I had also decided I was getting a new EVGA 750w G2 PSU and white Cablemod cables, with a 250gb and 500gb Crucial BX SSD pairing, two Samsung F3 1tb may have been going in too. And one of my old MSI 7950's.
I had the PSU and SSD in a basket, as I was going to add an item or two, but had been distracted with working on the PC. Lucky as that would have been another couple of hundred pounds worth of PC parts joining the now not needed NZXT case, Phobya RGB lighting, and Nepton 240M
I feel that CM's stand off's are at fault here, whether I am right or wrong I do not know, but it is certainly CM's fault the instructions do not mention stand off orientation as this could lead to exactly what I have experienced. Their little plastic insulator on the stand off is very small and thin, and held on by gum, it also moves when tightening, as I had to reposition one of mine.
Sadly when I wrote an email to Cooler Master UK looking for some sort of feedback or advice, they never bothered replying
