i just got a Card cooler XT from cardcoolers.com, for those of you who don't knwo what i'm talking about, it's basically just two giant 120 mm fans that go over your motherboard and produce 138 cfm to cool all your goodies. However, it's so powerful that when i opened up asus probe i noticed that my CPU fan rmp increased from 5075 to around 5320. It's a delta fan on the swiftech MCX462, just wondering if this increase is bad for the fan, like will it stress the motor or anything, or should i not be worried?
