i notice the same for my vega pulse.
in ur example im pretty sure the fans are even off.they should at such a low
temp. the rpm information seems to work as long at it goes up. but when the
temperature falls below 55=C2=B0C the fan are going to stop and the rpm inf=
o doesnt
get updated anymore and stays there.
