I just ran across a box of these. Had to buy the whole box to get them. These are 60mm square x 25mm thick, Run on 12vdc and draw .23 amps. They put out 24cfm and have 4600rpm. Rated at 36db and weigh just under 2.5 oz. They have three wires. Two for the voltage and one is an output tachometer signal - these were made for something that had to sense the fan was running. The red wire is positive, black is negative, and whit is the tach output. Asking $1 apiece plus shipping or 5 fans for $10 shipped conus. I have 100 of them. Paypal prefered
I am sold out. I will repost this add in about a week if it turns out that some buyers don't follow through.
THANKS TO EVERYONE WHO RESPONDED TO MY ADD!!
