So I'm using an MSI GTX 650 Ti Boost Twin Frozr III 2GB OC graphics card and it's working fine with no problem but its fans only spins when I'm playing a game and even then, they only spin for few seconds with little bit of noise then stop spinning, the game would still work fine and I got no issue but I'm worried that this cycle of spinning then stopping from time to time is a bad sign, is it normal for a graphics card to do that ?
