The powerstream is already sitting open on my desk, where it will lay until I get the quieter fans into it. The stock fans use a 2-pin connector, and I've been looking online for a 2 to 3 pin adapter, but I can't find any.

Is it possible to put a 3-pin fan connector onto a 2-pin connector? I don't have a soldering iron, and these Powerstream fans are driving me nuts. I've got some yate loon and panaflo low speed 80mm fans to swap in, but no way to change the connectors.
