[SOLVED] Fan Revving on start up for 2-4 seconds

[Deathbug]

Hi Everyone

I recently instsalled a 3700x+ b450m bazooka plus moba together with my already owned rtx 2070 z gaming+650 W PSU. But upon startup I know hear an intensive revving of what I can only imagine is my gpu for just a few seconds. What can the cause be and is it something to worry about?

Kind Regards

A lot of motherboards do this intentionally for all fans as a dust clearing mode. Many cards do it too, and some can even spin the fans backwards.

Hi BFG-9000, ok I did indeed check and the right fan of my gpu does the revving in the beginning while the left is idle. So this is nothing to worry about right?

It's actually a nice way to know the fan works, especially since nowadays it may not spin at all until things get hot. Think of it like the idiot lights in your car that all light up momentarily when you start the car, to let you know the lights actually work.
