The reason you cant find any guides for stock 754 and 939 HSF installations is because its soooooo damm easy. They've really got a good system for mounting the stock hsf's.
All ya do is line the hsf clips up with the ones on the board, sit it on the cpu, latch the side that doesnt have the lever in first, then push the other side down untill the opposite sides latch clicks in place. Then you just flip the leaver...and your done
Make sure your HSF has some sort of thermally conductive material on the bottom (eg. thermal paste, thermal pad). You should also verify that the HSF has been seated correctly...although the HSF wouldnt have mounted on properly if it wasnt seated correctly. This is a very easy task...if you ever have to use any noticible force, stop and check that everything is seated correctly.
