Ok, I did some experimenting today. The pinout for the fans looking at it from the end of the connector looks like this: |______| | 1 2 3 4 | where the top spikes are the key tabs on the connector. Pin 1 is ground, pin 2 is 12V power, pin 3 is the Tach sens., and pin 4 is the control pin. I supplied...

I already have these and they are really nice fans. They're Delta fans that are 120x38mm and produce 130 CFM at full speed. If I were to get new decent PWM fans, it'd cost me about $60 or more. So let's see a few dollars for a simple circuit, or $60+ for new fans. I think it's an easy decision. I me...

Hi guys, I found this discussion and thought you guys might be able to help. I have a Mac Pro enclosure and it uses fans made specifically for Apple, but I think I've figured out how they work. Now I just want to get them working with the temp control from the motherboard. Here's the situation: Thes...

Yeah, I hadn't noticed how old the thread was until after I posted. I found this thread from Google.

Hi, I've got a Danger Den (Liang) DDC pump running at full 12V @ 4500 RPM and it's isolated by a square piece of Rattlepad (visit secondskinaudio) that I had leftover from my car install. I also installed an XSPC res-top which made it completely silent. Before when I used a Danger Den acrylic top it...
