Ive been thier, Enzotech V1 CPU Block, Plastic top broke Spilling water on the CPU Mobo, Ram.
I notice when my Pump was making a empty sound.
So After i stopped then started breathing again this is what i did.
Mobo:
Removed, Used my leaf blower(Only thing i have that blowes, Other then the wife

)
Blew it for 5 mins, No joke, Everywhere.
Flipped it over left it sit face down for 24 hours.
100% working when i was done.
CPU:
I had the same burn marks
I used a NON metal scotchbrite and it clean right up.
Wiped off with methyl hydrate Let sit with mobo.
Ram:
Same as CPU.
Never give up Unless its 100% nogo.
Hope this helps
