February 17, 201313 yr Hi Guys, Sorry if this belongs in a different area or the data exists, but I've searched and read through many posts without finding an easy answer--and maybe an easy answer isn't possible. I will also say, I know nothing about linux--I simply downloaded the unRAID OS and it worked OTB (which I love!). I have a new build (working well) with a SuperMicro 5x3 SATA backplane...the chassis I used was the AZZA Helios910 which came with four fans all of which are virtually silent. My Corsair CX750 PSU also has a silent fan...counting the CPU and backplane fans, I have seven fans. All of them except the SuperMicro's fan are virtually silent. I'm using a BIOSTAR Hi-Fi A85W MOBO and the 5.0-rc10 Lime OS with three 3TB drives, no plug-ins (yet). I'm using the unit as a simple home NAS, nothing more. The SuperMicro fan is just driving me nuts with it's noise. Short of replacing it, I'd like to find a way to control the fan via software. I'd be happy if I could simply have it turn off when the drives shut down and turn on when they spin up. The OS reads and reports the drive temps just fine. I thought I might use the BioStar BIOS to de-tune the fan a bit by plugging the SuperMicro's fan lead onto [one of] the MOBO fan headers, but the BIOS doesn't give me any controls for fans except the CPU fan (that I can find). And I suppose the best solution would ramp the fan up as the temp increased...but again, I'm out for a simple solution. Is there a simple way to do this? Being a newbie and absolute beginner, I'm pleading for a simple and complete instruction set. Thanks for your help! Mark...

February 17, 201313 yr No can do. You need to control the fans from the motherboard, not the backplane.
February 17, 201313 yr Author Sorry if I was unclear... I have the fan for my backplane connected to the 3-pin connector on my MOBO...so now I'd like to know how to control it (i.e. via software or OS through that connection.
February 17, 201313 yr Ah! Yes, I misunderstood. Did you use the existing 3-pin fan? If so, I dont believe the PWM fan control modules like the unraid-fan-speed.sh script or in SimpleFeatures will work.
February 26, 201313 yr You can use this fan control plugin to control the fan speeds on your motherboard: http://lime-technology.com/forum/index.php?topic=11310.msg153187#msg153187. Obviously, you need to rename the plugin from .txt to .plg.
