I need to replace the whiney and failing northbridge fan on my mother's old Athlon PC. She will probably be slightly worried about me removing the motherboard to fit one of the blue Zalmans... so, as long as I can snip the pins and remove the old heatsink and fan, will using 100% of this thermal epoxy provide similar efficiency to normal AS5 plus ensure that Zalman will never become detached ? That's my understanding, can someone confirm ?
