Dark deposit from PC on Wall

My HP Workstation is making grey deposits on the wall behind it (about five inches away). No doubt this is coming from the fan.

Any suggestions as to how to minimise this? Can filters be added to the fan?

clean the dust out of it regularly

wouldn't want to do anything that might restrict air flow as this amy case overheating.

As FruitBat but there will always be a certain amount of dust so you could place a sheet of paper or card behind it to prevent it marking the wall.

Is it possible that you have your PC close to the floor. Raise it up at least a foot. That should considerably reduce the amount of dust being sucked in.

Are you sure that the mark on the wall is not the shadow of your PC? I thought the fan pulled air (and the dust) in, not out. You could move the PC further away from the wall!

Air is usually sucked in from side and blow out through the PSU or rear Fans (it is on mine)

It sits on a table 40mm from the ground.

Does the cat sit on it

What cat?

Looking for the more usual sources of dust.

If there is sufficient stour coming out the back to mark the wall, then there is very likely sufficient dust to clog the fans and fins of the heat exchangers. A good clean-out is on the cards.
