Fans dont spin all the time and if you have more than 1 fan they dont spin at the same time all the time.  
Hi everyone, just received my brand new PC this week and I've notice that my GPU was running kinda hot while browsing Google Chrome only (45 to 55 Celsius). I downloaded Hwinfo64 and saw that GPU fans were at a big 0 RPM.  Is it normal ? Am I the only one ? Some hot spots were barely touching 70 Celsius without doing anything. Finally I installed MSI Afterburner and played with the settings a little and now everything seems fine !  Do any of you had to play manually with the settings through a third party app to make these fans do their job ? I was starting getting nervous seeing those high temps going on while only watching videos on youtube.
