I am too ghetto for purchasing a shroud
IIRC the BIX has space to run screws all the way through the rad.
I would just get some 3-4" screws and make stand offs for the kaze fans and use duct tape as the shroud (I would try masking tape first cause it is less messy, but I think it would not handle the pressure of those fans)
Fans on the other side would just be for show
I have never had a fan like the Kaze, (reading hte specs) even my Panaflos are not that powerful. My old nidec BetaV was, heavy as hell, but you could lay it on the desk and turn it on and have to chase it lol
I would think the 120.2 would be severe overkill for NB/VRM but if you got it laying around...
JOOC, when is the last time you soaked your rad?
