Mac mini M1 fan noise clearly heard from seated position

Just wondering if it is normal to be able to hear the fan from the desk seated position. My new Mac mini is on my desk next to my monitor. Its by no means loud and there is nothing else in my room making any noise, its a very quiet room.

From all the reviews I just thought I wouldn’t know it was on which isn’t the case, although I do have very sensitive hearing.

If I put my ear right next to Mac mini then I can hear the same noise but also there is secondary noise, this one is intermittent like a accessing high pitched noise, fortunately this cannot be heard from the seated position as its far more intrusive a noise.

If its normal then I can live with, just wondering if its worth trying to get a replacement, I was thinking I will probably put the mini under the desk or further away from me.
