Removing Socket 478 Heatsink

[Waylay00]

Hello, I'm in the process of removing a Socket 478 heatsink in order to replace the CPU. However, I cannot seem to remove it. I found a picture of the heatsink here -

Anyways, I've already read through the instructions on the Intel website to no avail. With this weird retention mechanism, I can't fit a screw driver or anything under there in order to unhook the clips. Any help?

Thanks.

There appear to be thumblevers on one end of each chromed clip. If you push down on those, does it release the clips?

i use a flat head screwdriver between the bracket and the clip and ease off the bottom of the 4 corners. its a pita. if you get 2 on one side it will lift off.

Yeah 478 + heatsink mechanism = PATHETIC.
It's a hook mechanism. So you push down and .... pull out.

BUT! Best way to do it is to use a flat screwdriver. So much simpler
It connects like this

All of my S478's have 2 levers. You just flip the levers and the HSF comes right off.

Thanks for the help guys! Just performed my first CPU upgrade. 1.5GHz P4 to 1.9GHz P4. Thanks!
