My compaq presario came with a screw on heatsink made by avc. I even found an upgrade made by avc (open box) at newegg for $7. If you have the knowledge to remove the motherboard to install the heatsink backplate, I suggest you make the switch to the screw on type, since you've already ruined one of the push pin designs. Several manufacturer's make the screw on design.
Thanks. I have one of those I'd like to re-use, but the pins were mangled.
Incidentally, I've had no problems with the pushpin mounting, but then I've always made sure they were securely clicked, and I don't move my systems around a lot. I am not at all suggesting that SupremeLaw and others are wrong, but I suspect the problem isn't as bad as it's been made to sound.
I hate those push pins how come Intel came with such a bad idea to use oush-pins to secure the CPU cooling.
The one on the P4 was better that one can fall down and also you can't be sure if all the pins are locked correctly.
I just hope they will change that on the Nehalem CPU cooling.
Its a waste of moeny to buy another Intel heatsink better go for a third party one which provide more secure solutions like screws which will keep the cooling in place.
