Done lots of searching, but haven't found much useful info on this:
I put a fan/heatsink back onto a good MS-7191 socket 939 motherboard that i brought 2nd hand some time ago, and it just twitches back and forth (which makes me wonder how (or if) it was working on that board in the first place).
So i had four similar sized AMD fans that i tried, and here are the results (including the one just mentioned):
Black Red Blue 0.45A : Just twitches back and forth (and sets of BIOS No fan alarm)
Black Red Blue 0.24A : Twitches once (and sets of BIOS No fan alarm)
Black Red Blue 0.08A : Works OK ~2812RPM
Black Red Yellow 0.1A : Works OK ~3245RPM
Black Red Yellow Blue 0.3A: Works OK ~3125RPM
So, which fan(s) would meet this particular board's specification (the user manual doesn't state this)?
Interesting that the "0.3A" fan works, but the "0.24A" doesn't.
And, on the 3-pin fans, does the yellow wire being in place of the blue wire mean anything significant?
