Yea, i know what you mean. My fans constantly turn out and when they do, it sounds loud as hell like i have some aftermarket cooling system stuff. People always wonder that cus you can be at least 10 feet away and hear my fans spinning. Well the only thing i can tell you is to check the wiring to the fan relay. It might of gone bad. In the worst case, you might have to replace the whole fan unit but most likely its a wiring issue.
