So I went to check my miner online and noticed it had been offline for 45 minutes, i went to start it again and could smell burning, turned it on and the first gpu caught fire with like a torch like flame where the power connectors are attached!!! Has anyone heard of this? Why might it have happened?!

We are running 4 gigabyte7970's at around 75c and 673kh/s each In an open custom built frame. All the GPU's are on non-powered risers, could this have been an issue? we have a 1500watt psu running them.

Please could i have some advice, this is pretty scary as i also live on the 66th floor of a high rise building and it could have taken the whole thing down!!

Well, first off, let me reassure you that your rig on fire wouldn't take the whole building down ( I think Wink

)

Second, as for the cause of the fire, there could be numerous reason for it, from which the most likely one is that your VRAMs overheated, as those can run very hot. Could also be a simple manufacturing defect, in which case you just got unlucky. I hope you still got warranty.

As far as the risers go, I doubt those are at fault since if it was an issue with non powered risers than your motherboard would have fried, or the pcie connectors, but not the GPU.
