My Macbook fan is running very loud

My 2011 Macbook fan is running very loud while my laptop is on, no matter if I am streaming a movie or just typing a Word document. Is there a chance there is something in my activity that is causing this rather than having a bad fan? Additionally the computer is slow, especially the internet. Its only 2yrs old. Here is my activity report;

Welcome to Apple Support Communities


If the fan is working all the time, it looks like a sensor problem.


Run Apple Hardware Test > http://support.apple.com/kb/HT1509?viewlocale=en_US&locale=en_US Plug the MacBook Pro to its charger, choose your language, tick the box to run an extended test and start the test. If at the end of the test you see an error, copy it here.


It's probable that this is a sensor problem, but if the problem doesn't happen during startup, it would be a process which is consuming your CPU. Open Activity Monitor, select "All Processes" above "Show" in the toolbar, and order processes by CPU. Do you see any process which is consuming more CPU than the others?
