QFan on all fan connectors?

[Harry Muscle]

I'm thinking of buying the A7N8X Deluxe board for my new shiny Althon XP
2500+. One of the reasons I'm considering the A7N8X is because of the QFan
feature. However, I'm really confused on how it works. My first question
is ... does it work on all three fan outputs or only on the CPU fan
connector? If it works on all three fan connectors, what does it use to
judge the temp in order to control the fans? I'm guessing the Chassis
connector might use the motherboard temp sensor, but what about the Power
connector? Do you need to connect a Power Supply temp sensor in order for
QFan to work on the Power Fan connector?

Thanks,
Harry

On my non-dlx v2.00 board only the CPU fan header seems to be effected
by Q-fan.

The CPU socket temp needs to hit 50C or more before Q-fan will give the
CPU fan full power otherwise it spins according to the ratio you set in
BIOS. Q-Fan Speed Ratio Configurations: [10/15] [11/15] [12/15] [13/15]
[14/15] [Full Speed].

On A7N8X Deluxe revision 1.x boards, Q-fan does *not* work on the CPU
fan header; only on the PWR_FAN1 header. No, I am not mistaken. No, I
don't know why in hell they did it that way.

Seconded.
