Pentium 4 Heatsink Stuck
Posted 26 April 2012 - 02:01 PM
I am running a Pentium E5200 with the stock LGA775 heatsink (you know, the ones with the black pushpins). I want to remove the heatsink to clean it out and apply new thermal paste, but when I try to remove it the white grips remain stuck in the motherboard. Although I have rotated the black pins 90 degrees (in the direction of the arrow) and pulled them up, the white grips don't bulge when I try to pull the heatsink out. I can lift the heatsink about 5 mm off the CPU with the pushpins unlocked, but the white grips don't let me lift it off completely. I don't want to use excessive force because I am worried that I might damage the pins and/or motherboard. I've seen videos of other people pull the white grips out with ease, but for me they seem to be "locked" in place.
Any help will be greatly appreciated.

If you can see the pin from the bottom, try a paper clip or dowel of some sort to push it up from the bottom, don't use excessive force, just keep pressuring and you'll get somewhere with it.
Pliers are recommended for these projects if you use them with care, minimal forcing is always recommended!!
In the typical white Mobo stands (used to mount mobos to cases without screws) that lock through holes in the same fashion, a plier is used to squeeze opposing sides toward the center, or where the hole is that you must extract, if they are unable to squeeze back in, it would prove locked in the method that the HSF uses, as an example that's related
In Stinky's post, you just turned the locking mech to lock and tried to remove the heat sink, which is a simple correction

Another area of concern is always the thermal paste, it can harden to a cement like grip between CPU and HSF. For this normally the best procedure is gentle side to side twisting, as it become pliable, you can pull with added force in both directions
