A few tips before you start!

Enable CPU Overheat/Shutdown protection in your BIOS, say @ 70ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â°C for the CPU, so if something goes wrong with fitting the heatsink the system will shutdown when the CPU hits 70ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â°C, which is a sign of something not right and saves you from frying your CPU!

Enable the CPU Fan detect in BIOS, so if you forget to plug the CPU fan into the CPU Fan socket on the board you will get an audible or visual alarm when booting the PC to remind you!

Also, If the new heatsink has a step machined into the base, make sure this locates with the step on the CPU socket!! Otherwise the base of the heatsink may not sit squarely on the 4 pads on the CPU and may cause an air gap between CPU core and the base of the heatsink and cause overheating!

And don't go mad spreading thermal grease on the CPU core, just enough to spread a thin layer over the entire surface of the core. You can also rub (with a cloth) a little grease onto the base of the heatsink in the area roughly where the CPU will sit so it gets ingrained into the metal base, just press on hard while rubbing along the grain of the metal so it gets thoroughly rubbed in.
