Are you talking about powering the fan or what?
Whatever you do, dont pump current INTO the blizzard via the fan connector from any unregulated source - CSPPC users that did that regretted it.
To ensure you have enough juicem ,ake sure your 1200 motherboad is adquately supplied. As I dont have a PCI bus expander, I opted to use the original connector and the floppy header to feed power into the 1200 motherboard and my system runs fine, and thats with the BVision + 256Mb.
