CPU stuck to heatsink!

[ginandmilk]

This new build is stressing me right out!

I had a problem with my PSU but thats sorted now. In the process of trying to find the problem I took the new CPU out of the socket. The heatsink really didn't want to come off but when it did, it pulled the CPU out with it.

Luckily none of the pins are bent or broken, but the CPU is still stuck to the bottom of the heatsink. I've read several different methods for solving this problem, and a hairdryer / razor blade combo seems to be the best bet.

Just wondering if I can do any damage to my chip with the hairdryer?

Anyone have any experience with this sort of problem?

Thanks in advance.

What cpu is it, if its an AMD one with pins id check theres no bent ones. Hairdryer should do the trick nicely.

Is a X4 995. None of the pins are bent or broken.

I'm using the AMD retail heatsink that came with the chip which had paste already applied. But it was obviously too much because its oozing out from the sides around the chip.

I can't damage the chip with hot air then?

have you tried twisting it side ways, dont pull it, and hair dryer should be ok, heat the sink first though (not the cpu)and just keep trying to twist the cpu

Not unless your hot air would happen to be way above the TJ Max. It may be Thermal Adhesive instead of regular Thermal Paste.

This used to happen with my old AMD system everytime I went to remove the cooler.

It should come off quite easily once you heatup the HSF.

The old heat and twist worked wonders.

i normally just turn the pc on for 5 minutes before removing it.

Max Tjunct only really applies as an operational temperature. Powered off the chips can handle quite a high temperature.

Last time I had a heatsink "welded" onto a P4, I just popped it into the oven for about 10-15 minutes on the lowest heat level, and then while it was hot gently tapped the heatspreader with a thin screwdriver. Popped right off no problem.

Obviously dont preheat the oven, your only looking to get the cpu up to around 40-50 degrees C. If you overcook it slightly, just be carefull not to burn yourself on the hot heatsink.

For future, if you load the cpu until its hot and then poweroff and remove heatsink, there is normally enough latent heat left so that the heatsink will not pull the cpu from the socket anyway .

I've a slight fondness for the LGA775 socket due to the clip mechanism holding in the CPU but I haven't used an AMD processor in over 6 years since the Athlon XP's, so wouldn't know how the mechanism works on the latest generation AMD parts. Good to see you got it sorted mate!

A tip: Before pulling the heatsink from cpu, just twist the heatsink to brake the seal before pulling.
