yeah....You will be fine....just be carefull and test the h3ll out of it b4 you put it in to make sure it isnt leaking. There are enough people using them so I would guess that it should be pretty safe.
as for the fluid....even if it isnt conductive....I couldnt submerge my mobo in it.....I think that is just insane!!.....in the end he still ended up frying it anyways and still just missed the record. That is some serious overkill but its cool to see.
no doubt....he must have a contact or job where he can get it for free b/c that would just be plain stupid to throw money away like that....I'm all about overclocking but to go that far is just a bit to much.
I don't see how 4333mb/sec is even possible being that DDR433 isn't a very big increase at all unless the onboard memory controller really makes THAT much of a difference on 64bit systems.
