HP Pavilion dv7-4180us Excessive Fan Noise

When it comes to excessive fan noise, the general problem is cooling. Something is either blocking the fan from cooling the heatfins of the heatsink assembly or the heatsink is inadequately cooling the system.

A friend was complaining that their HP Pavilion dv7-4180us fan was excessively loud and constantly running. I offered to open up the notebook computer and take a look inside. What I found was the heatfins of the heatsink assembly was blocked up with dust and needed cleaning.
