gpu vrm burnt up

[kainobean]

ok so becuase i was testing diffrent ways to cool the vrms on my old 290x's i had made a metal heatsink that touched the vrms and screwed into the screw holes. well it turns out i should have done more research into the vrms used on the 290x and haveing them grounded like that and bypassing the filter caps was bad and caused a lot of high pitched noises under load. well eventualy one of the vrms burnt up and system shut down. everything is fine except now i have a vrm that is no longer on the card along with a big scorch mark when it was... 

 

this may sound like a bad idea but would it still be safe to use it for somehting like folding whihc dont push the card to its fullest like stress tests or games usualy do... im just wondering if one less vrm would put to much stress on the others or not?

 

it was the smaller vrm not the bigger ones so i imagine it didnt loose out on a huge amount of peak power.

 

lol i feel like a noob sometimes when i make stupid mistakes like this v.v

There is a reason why it comes the way it does and why most VRM cooling solutions just blow air over it.

^that is a closeup photo of the spot where vrm was

it came out better than i hoped and hopefuly its good enough for you to tell whats going on.

 

it dont look like there was any dmg to layers under it just the top layer and maybe when cleaned up a bit more it be fine.
