The heat sink on my PC Chips MB is coming loose. Anyone ever have this happen? After many lock ups and screen freezes, I took off my CPU to clean it and low and behold the Heat sink was sliding out of position. Can this be glued on with some type of "High Tech" adhesive? If so where do you purchase something like that? Pushing the Heat Sink back into place seems to have solved the lock-ups, so I would hate to now have to get a new MB. Thanks for any help you can give. People on this board are the best! Joel

You can use thermal adhesive between the sink and the cpu, but it introduces a problem in that you will never again be able to separate the cpu, sink, and mobo. (Because you will be locking the cpu in place under the cpu lever, then gluing the sink on top of that, which prevents any future raising of the lever) It sounds like the heatsink clips are not either not locking onto the socket tabs, or perhaps the clip on your sink is bent such that it is not creating pressure between the cpu and the sink.

You need to use Thermal Paste. You will have to clean all the old off first and then place a bead about the size of a grain of rice on the processor and a thin layer on the heat sink the size of the processor and about as thick as a sheet of paper. This is best done by cutting a square hole about the size of processor into a sheet of notebook paper and then use it as a stencile to apply the paste to the heat sink.

Are you talking about the heatsink on the CPU or one on a chipset elsewhere on the MB?

OtheHill, Its the one on the Motherboard, Its glued on there. Where I think others are confused is when I said about cleaning the CPU. Its the heat sink on the Motherboard. The reason I saw it was because this is a "Slot A" type CPU. When I took it off of the MB it exposed the heat sink on the MB. I then was able to see it sliding out of its place. I pushed it back but it still wants to slide away from its intended position. Joel

I believe that you can glue it back on with epoxy cement. For more details about this I suggest you post a query over at AMBMB.com. in the appropiate forum.
