I have an Asus P5B-Deluxe (not the WiFi), and I have been able to get
the 80mm fans connected to FAN1 and FAN2 working under fancontrol using
pwm in the winbond 83627dhg. Both fans are controlled by pwm4.
But the really loud fan in the box is the Zalman CNPS 9500 LED CPU fan.
pwmconfig didn't find any sensors correlated to that fan. But the MB
comes with software (QFan) that supposedly independently controls the
fan speeds of FAN1, FAN2, and CPU_FAN. For each of the three fans
mentioned, the BIOS has settings to enable/disable fan control, and to
set a fan control profile (silent,optimal,performance). However, none
of the settings seems to have any effect on any of the fans.
The fan comes with an adapter for the fan connection with a knob so you
can turn it down. But I want to be able to control it programmatically.

But I want to be able to control it programmatically. Yes, Zalmans are nice. They do have an additional knob to turn down the speed. Have you tried manually shutting off all the fans? Write 1 to pwm1_enable, pwm2_enable, pwm3_enable, pwm4_enable, pwm5_enable. Then write 0 to pwm1, pwm2, pwm3, pwm4, pwm5. As you said, pwm4 controls both case fans. So I would expect when you write 0 to pwm4 they shut off. I would expect the same result for the CPU fan when you write to pwm2 or pwm3, but I'm curious what result you actually get. Note that I am suggesting bypassing fancontrol and just go directly into /sys/class/hwmon/hwmon0/device and echo "1" > pwm1_enable, etc. Hope that helps, David ^ permalink raw reply [flat|nested] 4+ messages in thread

I'm following up because I discovered the CNPS9500 LED is a three pin fan. It looks like I should have gotten the CNPS9500 AT. It is the same thing except with a fan that supports pwm control. Has anyone successfully controlled this fan connected to the CPU_FAN header of the Asus P5B Deluxe? ^ permalink raw reply [flat|nested] 4+ messages in thread
