hi guys, i posted before about getting a replacement chipset heatsink and fan. i've got one now, but i need to remove my original heatsink from the chipset. any ideas? i've got an asus a8n sli deluxe and i have successfully removed the fan, but now the heatsink is pretty well stuck on there. i have tried pushing the two black plastic pins with springs down whilst twisting and pulling gently to release from the thermal compound but to no avail. anyone else have an idea? i'm slightly worried the chipset might come off with the heatsink if i pull too hard.
