Help! My fan is so loud! What is going on?
My HP ProBook 4520s fan is really loud and seems to be running a lot. My laptop is warmer than usual too.
A 15.6" business notebook released by HP in 2010 that replaced the 4510s.
Its a common sign that your computer might be dusty inside. On top of that, your laptop is about 6 years old now.
When your fan starts going crazy, open "Windows Task Manager" (By pressing Ctrl + Shift + ESC key on your keyboard).
When "Windows Task Manager" shows up, go to the "Processes" tab, click on "CPU" and take a screenshot using "Snipping Tool". Once that's done, go to the "Performance" tab and take another screenshot.

Reply to this question and post your pictures here. We might be able to help you out. I have a feeling you might have a lot of programs opened at the same time, thats why your computer fan is going crazy.
if taking away the dust only makes the fan work les often, but doesnt help with the noise it makes when it runs, your fan probably has a liquid bearing. if it is constantly noisy when it runs the bearing is dried out. you should take the fan out of your laptop and use some silicone spray on the bearing to make it wet again.
