Uses for 6 Delta FFB1212EHE Fans?

post #1 of 10
Thread Starter 
I've always loved these fans, just for the sheer insanity of them, and I recently was able to get 6 of them new for around $35 total. Only thing they are missing is the 3 pin connector on the end, but I can just use jumper wires to connect them to anything. The real question is, what useful/silly/stupid things can I do with these beasts? I'm pretty sure they would fry most fan controllers, so even powering them may be a bit of an issue.

Well if you ever wanted to have shorter fingers this is your lucky day.

Honestly though, I would just use them as benching fans. Or make some cool slow mo videos of them them shredding stuff for youtube.

I did consider something like this, though I'm sad that they don't quite appear to have enough thrust to lift themselves.

but a couple or one in your rig and play around with voltages see how quite you can get them, Wish I could get them in my country mad.gif

I found them at a surplus store. I could have bought about 20 for only $100 but that was a bit overkill. As for voltages, I hooked it up to a bench power supply, and the lowest voltage it will run at is around 3V, but it needs around 4V to start, and 3V for continuous use. Its actually quite quiet at around 3-4V.

That makes them a bit of a pain in the A** to set up at 3v. you should do some testing, try benching your rig with the stock fans than again with the Delta's at full speed. it would be interesting to see the results.

Keep me in mind if you ever wanna sell a couple

Get an amp meter in the circuit so you can make a good call as to what you face.

Well, they are specced at 3A @ 12V, but I haven't been able to quite run them at full because my bench PSU has a current limit of 2.5A. I'll have to wait to get back to the lab before I can run them at full voltage and much higher limited current.

I have some of these fans as well, amongst the 1000 or so I have here. I'm buliding an AMD AM3+ with an 8 core and it's running warmer than I'd like. How do I rewire the Delta Fan to plug into the PWM 4 pin connector on the Asus M5A99FX Mobo? The only docs I could find mention the red, black and blue wires but don't say anything about the yellow wire. Also where can I buy some of the 4 pin connectors? If somebody wanted to coach me through it, I'd send them a couple of these fans. I'll have 7 left after I use 2 in my case.
