....Ten years an AMD fan, but the Fan couldn't keep up. Just returned a
Phenom processor Quad 9500 with Al fan when the motherboard started beeping
at me. Did something I haven't done in fifteen years, Q6600, it not true
quad but doesn't have cache problems. The Fan was undersized in my Box.
Current Fan settings on my new Q66 with ECS G31T-M...
AMT bios
Smart Fan Start PMM value... 0
Smart Fan Start Temp. (C)... 37
CPU DeltaT... +5
Smart Fan Slope PWM Value... +15 (PWM/C)
CPU Fan Full Limit Temp 45C
Being green, slowing the fan down when there is no load is important, these
settings give me at idle,
CPU Temp 38C or 100F
CPU Fan Speed 1070RPM
The fan Tops out 2050RPM at 45C.
Comments?
What Fan setting are you using? I figure full speed at 45C leaves plenty of
padding before my ECS G31.... shuts down at 70C.

A long time ago, I was into overclocking, still fun, but no longer feel the
need to be on the bleeding edge. But, still fun to talk about. On article
on Tom's Hardware on overclocking, he mentions cost of running for a year.
Several hundred for eight hours a day.
Yes, any old fan settings are probably fine as long as it's spinning the
fastest it can when the cpu is the hottest. But, the green part of me like
lower recurring costs, the power bill.
I've been thinking about it a little bit more and what criteria is best for
something other than spinning the fan full speed. I didn't like the default
fan setting on my cheap motherboard. The default was disabled, no variable
fan.
Start PMM value was 50 with a range of 0-128
PMM value of 0 gave half speed on the fan.
CPU Fan Full Limit Temp was 69 degrees, only one degree below 70 (my
shutdown temp) and way to close for me.
Current Fan settings on my new Q6600 with ECS G31T-M...
AMT bios
Smart Fan Start PMM value... 0
Smart Fan Start Temp. (C)... *37
CPU DeltaT... * * * * * * * * +5
Smart Fan Slope PWM Value... +15 *(PWM/C)
CPU Fan Full Limit Temp * * * 45C
I was rethinking these settings I came up with, and think I'll modify them
again with different criteria that is the greenest I can think of, and the
safest in terms of temperature, not running at the bleeding edge.
Smart Fan Start PMM value... 0 ----------- Fan is spinning the slowest
Smart Fan Start Temp. (C)... 37 ----------- Adjustment for CPU Fan Full...
CPU DeltaT... +5 ---------I have no idea what this does
Smart Fan Slope PWM Value... +15(PWM/C) - Maximum rate of change of FanSpeed
CPU Fan Full Limit Temp ??C ------- Temp at 100% CPU w 100% FanSpeed
in the Summer.
My adjustments are Start PMM value, Start Temp, DeltaT and Slope.
CPU Fan Full Limit Temp is the outcome of these settings.
This will give me full fan speed at max temperature for my heatsink and fan,
and will give me the lowest power usage at idle, and will give me the
smallest temperature change of the CPU/Motherboard from idle to full speed
(reduces thermal cycling).
Anybody know what CPU DeltaT does? Should i reduce it to zero?

Dear AMD,,, (Fan settings, what do you use?) 
Linear Mode
