hi,

See attached pictures. This is an old Intel Brookdale 845G motherboard.
HOW to remove fan from this motherboard ???

When I move the white clips on top, sink & fan body moves a bit, but does not come out. Entire body doesnt twist or turn.

Thanks !!

If you are 200% certain the retaining clips have been released, then it is likely the TIM (thermal interface material) has bonded the heatsink to the CPU die. Forcing the HS by pulling risks damaging the CPU and the CPU socket - destroying the motherboard.

See this YouTube video to make sure you have the clips free. If still stuck, what you need to do is get the CPU warm. Hopefully it still works as running it for a minute or two should be enough. Then when warm and with the retaining clips free, grab and twist the heatsink, WITHOUT pulling. Just twist back and forth, back and forth until the cured bond breaks, then you should be able to start pulling, and hopefully it will come free.

Hopefully, the wrong kind of TIM was NOT used on the CPU. There are adhesive TIMs used to attach heatsinks to devices without a clamping mechanism - like chipsets and GPUs.

Make sure the PSU is unplugged from the wall and touch bar metal of your case interior BEFORE reaching in.

That looks like a clipped design. My money would be that the headsink is still clipped. Regardless of the white leavers, many of these clippy ones were used as well.

Entirely plausible the thermal paste is bonded to the processor as well. If this is the case then it will probably come out with the heatsink still stuck in place but this will force the processor out potentially damaging the pins (these 478 processors were the last Intel "pin" based processors - 775, 1155 and 1156 have the pins on the board and a better holding mechanism for the processor).

Thanks mate. You tube link really helped !
