Some (not all) of the A64 mobos have a 4 hole pattern around the
cpu socket. To get to it you have to remove the plastic/metal hold down unit that the
mobo comes with. Then you can mount your waterblock using the 4 holes. But be warned!!! So far I know for a fact that the 4 holes pattern is in a differnt layout from the mobos for the XP to the A64. I had to have a custom top cut for my RBX to pick up the locations. That was on the ZNF3-150, As for the Abit
mobo, I will find out the location of the holes soon and have another top cut to fit my S-RBX..... Hmm or maybe just have aonther S-RBX made so I can have 2 of em
Or you can use the plastic/metal hold down that comes on the A64
mobo to mount your waterblock/heatsink, but I don't like the ideal of only having 2 points of pressure. This would allow for "rocking" if your are not very careful. And the die on the A64 (assuming you removed the IHS) is very, very fragil. I have already heard of 2 ppl crushing/cracking the die of the A64 after they romoved the IHS. One guy was still trying to apply the 75 ft/lbs of force that AMD recommend (but that is with a IHS inplace) and it just crumbled it. Once you remove the IHS on the A64, I was mounting it with the same sprimg pressure that I would mount my barton 2800. This seemed to be a good solution, since I have already mounted this naked A64 over 10 differnt times now, and still no chip/cracks.
Any case, good luck to all that venture down this path of extream cooling!!! It is a hazardous journey, but can be very good for temps!!! Just removing the IHS dropped my temps by 12 deg C right away!! (excuse my spelling, I have a slight hangover from lastnight........ Oh and Happy New Year to all)
