12VDC 80MM COOLING FAN, DELTA FFB0812VHE

Great Little fan

I bought about 20 of these fans for various projects and was quite impressed with them. They are thicker than most 80mm fans on the market and may not be suitable for all locations and they do draw several times more power than most 80mm fans. If you have intentions to plug them into a motherboard make sure it can handle the extra current. Compared to a typical 80mm fan these move way more air. I have no testing equipment to gauge if they meet there claimed CFM specifications so this is just my opinion but it would not surprise me if they not only met but exceeded their CFM specs. The construction is good and feel solidly built. Overall very pleased.

My crazy project using them:
After my first purchase I ordered another 40 of these. I had this kinda silly idea. I connected 36 of the fans together making a rectangular window fan for my basement. I hooked them up in series pairs so I could use a 24vdc power supply for them. I figured 18 sets at a bit over .5 amps each was as much as my 24VDC 10A supply could handle. Moment of truth, on my bench I plugged the PS in,they kicked on, and sent things flying, quite an impressive breeze. Just as matter of course I put a meter to the PS, it was set to only 23vdc. I had to see so I cranked it up to about 26vdc. The fan's immediately picked up speed and the breeze turned into a small hurricane. Really kinda fun. I also picked up a couple of small low speed motors here. I'm rigging them up so one button push will unlock then open the window. Then lower the fans into the window and turn them on. Like I said, a kinda silly, yet fun project. -Eric
