I echo this sentiment. It would be good to get verification of what fans were actually bought. So far, this has been the only info provided:
But Brian listed more than one fan a page or two back. It's necessary to know which one is being used.
In addition, it's necessary to know whether the four-pin connector has the standard black, yellow, green and blue wires. If not, it will be necessary to do some more work to figure out the wiring.
