Chassis fan connection on P4C800-E

[BP]

My P4C800-E D has a connection on board for a chassis fan, but my chassis
fan in the Antec Sonata only has a 4 pin power molly coming out of it. The
Seasonic power supply also does not have a dedicated chassis fan power
connection. The fan spins full speed constantly. There are no more wires
left to hook up anywhere. I'd like the case fan to be regulated by case
temperature or have a speed adjustment. I was hoping Q-fan on the Asus would
do that, but it can't if there is no connection. Is there something I'm
missing, or an add on solution?

Q-Fan is for the CPU only. The Chassis and PS Fan connectors are there to
power/monitor additional fans, not control their speed, IIRC. Typically, a
PS with a three pin fan connector only has two wires in it, used to only
monitor the RPM of the PS's internal fan. My Antec TruePower PS has this
feature, as well as the ability to control the speed of Case Fans based on
temperature.

Why not use the custom True Power 380S Antec power supply that normally
comes installed in the Sonata case?
It has the required fan connectors.

I didn't think you could get a Sonata case without the power supply
included.

Directron.com will sell the case w/o power supply. I wanted a super tornado
because of the 120mm, low rpm fan. I'm trying to build a quiet case and
wanted all 120s in it. Maybe I was thinking too much.
