M4500 Fan always on

So my fan is almost always on at 2600 rpm, even when my processor is at 50 C and at a lower multiplier state. The temperature doesnt go lower. Also, I have active thermal management on in the power settings, but I dont think it used to be on almost ALWAYS, as it is now. I have opened it up and blown some dust out. I also have a cooler master elevated stand, but other than that, Im not sure what to do if I can do anything, or should I do anything? Thanks.
