GS65 High Fan Speed on Startup

Recently, my GS65's fans turn on high speed whenever I start the computer up. This happens from the second I push the power button until a little after the Windows login screen comes up. Then the fans return to normal. I'm guessing maybe a recent Windows update has caused this? Has anyone else experienced this recently?

My computer: MSI GS65 8RF Stealth THIN-053

 

This should be perfectly normal and quite a lot of gaming laptops perform this exact way, im not 100% sure if this is intended as a pre-cooling feature or if it is a self maintenance feature that blasts out any trapped dust to prolong clean heatsink fins.
