Can of compressed air, start spraying
I heard that the PSU dust filter prevents good airflow.. is that true?
If I decide to add the dust filter (after spraying) I will tape the filter on the bottom of the case, just so that I don't have to dismount the PSU every few months.
I have one little concern though (would you please answer?!) :
... when blowing with the air can, should I just flip the case on the side and blow right underneath the PSU? (instead of dismounting the PSU and blowing on its fan?)
