Upgraded to a Arc Midi R2 a ~6months ago. The computer has been on 16/24hrs a day, everyday, barring holidays/random things.
Took the panel to see if it needed any cleaning and lo and behold.....there was nothing to clean....
Warning: Spoiler! (Click to show)
Not the best pics, but you get the idea. I never realized how much dust those filters keep out
Not bad at all. Did you get a pic of the dust covers themselves? They must've been full of dust.
I still remember opening a laptop 3 years after buying to find a solid block of dust blocking the heatsink which explained why it was overheating every ~2 mins.
