are gpu fans suppose to spin when you boot up your pc?

[chensonnyy]

I turned on my pc this morning and when everything was starting to boot up, one of my gpu fans started to spin (quite slowly) and stopped once everything was booted up. Should i be worried?

Many modern GPU's spin initially but then turn off if the temperature is below a specific target such as 60degC.

As long as the fans startup under heavy load it's fine.
