Xbox one X fan noise

So I bought an xbox one x and I recently noticed that sometimes while using it that the fan sometimes sounds like itäs slowing down. To better explain, I haven't noticed anything weird with the console, it's working as it should since I bought back in november
and not a single problem so far. But I just noticed in the past days that sometimes when you hear the fan working to take out the heat, from time to time it sounds like it's about to slow down on the rotations, but that only lasts for a second and then the
usual sound comes back. I only noticed this while being in a game, when I am on the dashboard or on netflix the xbox is whisper quiet. And another thing, sometimes while playing 4k hdr games, after a few hours of playing every 20 minute I start to hear to
fan revving up a little and the going back to normal.

So I was wondering if somehow the unit is not ok, or if I am just paranoid?

Xbox one x fan

So hey, i recently bought an xbox one x and the fan makes a weird grinding noise when im playing games, is this actually normal?

 

Xbox one X fan noise

Wolfenstein II: The new Colossus and Warhammer: Vermintide 2 are both Xbox One X enhanced games that are being rendered at 4K, which is more taxing on the graphics hardware, and therefore produces more heat.

And therefore the fan of the console has to run faster to get rid of the heat. So the fan being louder compared to whenever you play a non-Xbox One X enhanced game, is normal.

I don't know your actual speaker or headset setup, but whenever I play on my Surround Sound system or through my headphones when my wife is asleep, I don't hear the fan on my console, no matter what game I play.

While the console is quieter than other consoles when you play "normal" Xbox One games, watch Videos or have the console idling on the Home Screen, games that demand full processing power because they are Xbox One X enhanced, will cause the fan to spin faster,
and therefore being louder than normal.

 

As far as I could tell with mine, it's normal since it has a different kind of cooling system (liquid cooling) compared to the other Xbox Ones.

My One X is typically dead silent. Only during games does it start to have that ebb and flow of a very occasional, brief burst of "swoosh"!
