- this video explains why a poorly adjusted fan clutch will make the fan so loud.
When the new fan clutch is prewinded too tight, it just need a little heat to open the internal valve to fill the internal space between the shaft plate and the clutch housing. That will increase the fan's relative speed compared to the engine, and the faster the fan runs, the louder it gets.
