With regard to your broken processor socket heatsink clips. . .
For socket 370, socket 7 and its predecessors; thermal epoxy (i.e., glue) is easy and worth considering. I have a few heatsink/fan combos that clip directly to the processor itself. These are for older 486 systems. I don't know where to obtain them today and I am doubtful if anyone made them for Pentium processors. The heatsink/fan combo on most 586 processors requires the clips to attach to the MoBo. The paperclip idea maywork, but you need to be careful when attaching anything metal to you MoBo. If you accidentally create an electrical contact somewhere on the board, you may fry something. NOT GOOD. If the system is not state of the art, another option is to purchase a new MoBo.
