Well, I bought two 4-pin fans and got the script working. So, now at least I know I can control them. Since my motherboard only has 4-pin connectors, it is my understanding that I really can't use anything but 4-pin fans. I ordered the remaining 4 fans and they should be here on Tuesday. Then Ill run a parity check and cross my fingers. Thanks everyone for your help and suggestions.

Well, that's step 1. Like I said before, Linux isn't my first language. So, once the new fans get here, Ill then see if I can get one of the scripts working.

I think I came up with a plan... since the motherboard has plenty of 4-pin connectors, I ordered replacement 4-pin fans. I wont be able to use the backplane plugs, but thats OK. I also had to order new "hot-plug cables" since they were only 3-wire. I was afraid I wasn't going to be able to find those and I was going to lose the hot-plug capabilities of the fans. Hopefully the BIOS will control these 4-pin fans without needing a script.

You will have to excuse me as Linux is not my first language! So, basically, I purchased a SuperMicro SC933T-R760B and a SuperMicro C2SEE-O for a new unRAID build. The fans in in this case scream (at almost 5000rpm) all of the time. I have tried hooking them up to the motherboard and the backplane. All of the fans in the case are 3-wire fans. In BIOS, there are three options: Default, 4-wire Super Quiet and 4-wire Workstation. I have tried al three settings. My guess is it doesn't matter since none of the fans have 4 wires. So, my question is, where do I go from here? Will any of the scripts on these pages slow my fans down to a more livable speed? I suppose I could get a fan controller, but I would really prefer not to mess up this beautiful case. Yes, I know I purchased a "server" class chassis, but this is ridiculous. All of my HP Proliant DL-series servers (running Windows) slow the fans down after a few seconds of booting. Thanks!
