Now my 10-...rules files in /etc/udev/rules.d/ looks like this:
RUN+="/bin/sh -c '/bin/echo 1 >
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/hwmon/hwmon1/pwm1_enable'",
RUN+="/usr/local/bin/nvapoke e118 80000002"

During boot, it sounds as if it gets triggered several times
(noise-silence-noise-silence), but it ends up with a silent gpu fan when the
graphical desktop has started.
Startup logs are flooded with messages like:

nvapoke:473 conflicting memory types e8000000-f0000000
uncached-minus<->write-combining
reserve_memtype failed [mem 0xe8000000-0xefffffff], track uncached-minus, req
uncached-minus
