I can't stress enough, to use extreme caution when installing this HSF. If you thought installing a clip based HSF, with a screw driver that could slip at any moment was scary. Just picture crushing your Athlon XP core like a 57 Chevy in a car crusher. So be very careful. Oh yeah, since your going to be handling your motherboard make sure you're grounded. Some surgical gloves might also be a good idea due human body oils and electronics don't always get along.
