That's seems too low for a laptop, I don't think it can be trustworthy :-)

I see two problems here:
1/ First thing to do is getting the real temperature values. If the
computer is really hot, the fan should be on to avoid damages. If you
reduce the revolutions of the fan because is too noisy, you can break
your notebook.
2/ If temperature is okay (and computer is not hot), then the fan should
not be activated. Then, why is on? I dunno, maybe a bad ACPI or a buggy
BIOS that provides wrong/fake values to the system or it can be also
because the replaced fan is not fully compatible with your notebook's
motherboard (I hope you have purchased an original spare part).
What's you notebook brand and model?
I ask this because every manufacturer provides a different set of tools
aimed to control fan speed but be aware that manually tweaking the fan
speed can have severe consequencies for you computer.
