So i pushed my sapphire plat edition rx470 too hard on custom cooling using 1.25v.
Heat wasn't the cause of failure but the current draw was too much for the 4 phase setup.
I've killed one of the lowside mosfets part number mdu1151 h81705gp.

I've tried ebay and searching for this particular mosfet but haven't had much luck in finding it.
What are my options, i bought the card from overclockers, but obviously my warranty is void,
Is there anything sapphire could do, or is it now an ornament?

I'm sure AMD will release a driver update and fix the issue, improve performance too
 
I would contact ocuk im sure they will do everything they can to help, maybe they can send it off to sapphire so they can try repair it before ya bin it.

Good on ya admitting ya broke it though, a lot of people nowadays would just send it back after they broke it hoping it gets replaced at the companies cost.
 
In the ideal world you're either going to want a hot air or IR rework tool to get that off and get the new one on. Such a high power device is probably very very well connected to as much copper as possible to dissipate heat, making casual soldering iron rework somewhat tricky. A quick and dirty option is to drill a suitably sized hole in a metal plate and blow a paint stripper gun through it at the part ;). And of course flux..
