Paul, is that fact, urban myth or just humour? I was given two redundant pcs which used the FIC VC35 motherboard and both had only two of the loops shown, the chipset heatsink hanging on by one loop. As I found a loop loose in both of the cases I was baffled as to the reason and had presumed that this was someones attempt at making the pcs unworkable before they were disposed of. These desktop pcs were 4 years old and were/are still working fine. I'm no dab hand with the soldering iron and after my first attempt the loop pulled out within a couple of hours. The second attempt was successful after positioning the legs through the holes and bending them gently in different directions before resoldering. I'm not sure that you would be able to use two clips at the same time. If you look at the angle of the heatsink in the photo you can see that it's not square to the motherboard and it has to be twisted even further to get the hooks through the loops. A second clip would require the heatsink to be twisted in the opposite direction and the first clip would seem to prevent this or perhaps the judicious use of a pair of long nose pliers is warranted and hope that the 'spring' isn't taken out of the clip. However as you have much more practical experience I must bow to your superior knowledge. One last point, although I managed to find bios, sound and motherboard drivers when I reinstalled the o/s none of them were needed, XP SP2 found all the devices and supplied its own drivers.

For some reason, the parts here look like they were meant for one another. http://www.xbitlabs.com/images/mainboards/i845pe-roundup/asus.jpg Paul
