Thinkpad T410 fan control

Isimsiz
Hello.
I've installed OpenBSD 5.6 on my Thinkpad laptop, everything looks fine,
but i have problem with fan. His minimal speed is 3500, even if i use apm
-L (or apm -C).

http://pastebin.com/wUY8MqjX - here is my dmesg output.

sensors:
 sysctl  hw.sensors
hw.sensors.cpu0.temp0=33.00 degC

hw.sensors.aps0.raw1=505 (Y_ACCEL)
hw.sensors.aps0.raw2=519 (X_VAR)
hw.sensors.aps0.raw3=505 (Y_VAR)

$ apm -v
Battery state: high, 99% remaining, unknown life estimate
A/C adapter state: connected
Performance adjustment mode: manual (1199 MHz)

How can i decrease my fan speed? because laptop works in the night and its
too loud.

It's 59 degC at the PCH, I think the fan would likely run that fast if
the PCH were that hot.
