Extremely Load and Dangerously Close
20 - 30 minutos
The right fan had started to develop the angriest of sounds, think two lions trapped in a blender, with bees! It was so load I could hear it from another room! So I fixed it!
It was stupid simple. In out, less than 10 minutes.
If your fan ever sounds like it's trying to chew up large gravel, don't bother spraying it with compressed air, the motor is dieing, replace the bugger!
