I have an early 2011 i7 MBP 15". I notice that from time to time the fans are running but for no apparent reason. I haven't run any programs or done anything. When I check activity monitor the CPU is being used at less than 10%. Time Machine isn't on. I don't understand what is causing the issue. Any advice?
