Hi, This is my first post so bear with me. I have a 650 MHz AMD Duron and my old CPU Cooling fan/heat sink combo had a freakin death grip on my CPU. Attempts to gently remove the clips holding the fan on the ZIF socket failed. The end result of force, (I know, never a good idea) however, was that I broke the clips off the ZIF socket. Frusterating. So, now I need to find a cooler ( I was trying to get a better one in the first place) that clips either directly on to the CPU or one that clips to the remaining clips on the corners of the ZIF. I would like to know what are the best at keeping cool and low noise. Thanks.
