Tried using compressed air in reverse to clean a PSU and it backfired hard

So I had this old Corsair PSU that was caked with dust. Instead of blowing it out the normal way with canned air, I figured I'd vacuum it from the intake side to pull the dust out. Worked for like 30 seconds then the fan spun up crazy fast and made this grinding noise. Pulled the thing apart and the vacuum suction bent the fan blade bracket. Learned my lesson - just stick to blowing dust out, don't try to reverse engineer the airflow. Has anyone else wrecked a part doing something that seemed smart at 2am?

Ah man that sucks, I've totally been there with late night computer tinkering gone wrong. The fan blades are way more fragile than they look and that vacuum probably pulled way harder than you expected. Hope the PSU still works after bending it back or you can scavenge a replacement fan from somewhere.
