Hi Everyone, 

I have a problem: the fan above the CPU position. I don't know what it called. I looked up the Alienware Aurora R4 manual, and there is no information about this part.  Maybe it is a heat-sink fan. It starts to make noise, and I want to remove this fan to replace a new one that can be better and more quite. But, I don't know how to remove this fan on the motherboard.  

Does anyone here know about this part? Please help me out. I attached a picture for you guys to see easily.
