I did some searching on this and realy couldn’t find clear instructions anywhere on how these things should be wired up. If anyone is reading this and really understands how to configure the fan then please post here.

You can get fan cable splitters like this one:

Rosewill RCW-310 12″ /Fan Power Y Cable

In the end I tried a lot of permutations and this one worked the best for me but I couldn’t say I’m completely clear as to why.

Sorry I can’t provide a more definitive answer.

I, too, went with a 3-pin CPU fan and a traditional setup of the rear case fan connected to the SYS FAN connection. No front case fan (yet). Running at 100% the CPU fan was fairly loud. With some bios tweaks (setting it to run at 50% with CPU under 50 degrees C) I was able to make the CPU much quieter. I’m actually going to tweak it a bit more (down to 40%) because the CPU never seems to go above 30 degrees C even under decent load.

But after quieting the CPU fan I now notice the sound from the rear case fan. Don’t get me wrong the Home Server computer as a whole is much quieter than any other PC in my office, but I’d like to hush it just a bit more. I was thinking about daisy chaining the case fan with the cpu fan so it, too, would run at 50% (or 40%) unless needed.

I was wondering if I should just manually splice the wires or go with some kind of splitter. I would assume with both of them being 3-wire setups that all 3 of them should be spliced together? But maybe I should just pull power and ground for the case fan from the CPU FAN and have the display line for the case fan go back to the SYS FAN connection. I guess I’ll test it out a bit and see how things work out.

Thanks again.
