couple of months ago i heard a sound in my case it sounded like something shot into one of my fans but when i looked inside i didnt see anything. few months later i took apart my computer to clean all the dust out and one of the clips on the northbridge i think? heatsink was just hanging. i also found this other U-shaped metal piece in my case i'm not sure what it belongs to. is there a way to attach the heatsink back to my motherboard? right now i just put some arctic silver 3 on and pushed the clip back through the motherboard, but when i look on the back of the motherboard it looks like the clip is not going through all the way compared to the 2nd clip thats on there really good. heres a picture i did in paint if its too confusing ill take some real pictures.
