Radiator touching sound card question

Hi there,

Now I know that there shouldn't be anything touching anything else in your rig but I thought I might just ask anyways. Please don't flame me with -- "um nothing should touch it, dur"

After installing my new motherboard -- the massive video card that came with it is BARELY touching my radiator in my case (liquid cooled) -- the little metal prong things on the back of the sound card.

Do those little metal prong things have a lot to do with anything critical? or is it known that if maybe one gets barely touched or bent its fine??

Can I flip the radiator upside down? so the tubes are running out the top? (hence not touching my soundcard?

I havnt even turned on the rig to see if it works yet because I'm waiting for my waterblock to come in the mail.

Any opinions on this would be awesome! :]
