I just bought an SK-7 and plan on putting it onto an MSI-K7N2G-ILSR. The possible problem is that the motherboard came with no mounting holes to give extra support for a heatsink and the SK-7 weighs in at 485g without a fan. Will the socket on the board be able to hold that much weight or am I in for an adventure. I would appreciate any input on this matter before I start lapping the heatsink just in case a return is inorder. Thanks very much.
