Introduction: Silence of the Fans.
tick tick tick tick tick tick ....... tick......tick ticktickticktick.........sqweek, tick, tap tap tap tap tap....
Man oh man that sound is annoying, it either keeps me up at night or wakes me up at night. Giggling the fan does not work, graphite powder did not work, something must be done.
What I did was line the housing with a inner tube. The housing needed it because there are lots of wires and wire nuts which tap the sides of the housing.
then place other bits of inner tube where metal meets metal.
