I was seeing very high NB temperatures. When I purchased the cMP I was told one of the clips was replaced with a bolt. I have removed the two CPUs and found the one original clip broken and the heatsink was loose. I have ordered what looks like the (based on the name) correct replacement heatsink mount clips from eBay however they are much larger. Please see the attached photo: L: metal bolt (no nut, I think the previous owner had to tap the cpu tray) C: original clip broken off R: new eBay replacement clips When I install them do I need to mod them?
