My fan will be running at 3750 RPMS while idle at 75% fan speed. If i put my computer under pretty much any load it drops to 3570 RPMS consistently. Is this normal? Shouldn't it be higher under load. What could cause the fan speed to drop? I would really appreciate any help because I'm thinking about RMAing the card. It has a lifetime warranty and is going through a heating problem. Not to mention the bios on the 560ti limits my software to 75% fan speed instead of 100%
